I Bought an 80,000 lb Excavator for ONLY $7,500! What Could Possibly go Wrong? 

Two free tips on the DEUTZ engine. Hot pressure wash completely the interior of the engine, cylinder liner fins, oil cooler and cooling fan. This is a MUST to keep the operating temperature of the engine under control and not to size a piston. All should be completely clean 100% without any grease, dust or paint.. Second tip: when you operate a DEUTZ engine you should keep the engine speed ALWAYS above 80% of full throttle rpm. If you operate it to slower peeds, the engine cooling fan will not provide enough air to cool it and you will overheat the engine and seize a piston. Bonus: always keep all air cooling compartment covers and seals correctly positioned for not to escape any cooling air and all the air goes through the liners and cylinder head fins. Enjoy your Liebherr.

There is a “no spill” adapter that threads onto those fittings, that has a hose on it, so you can eliminate the mess, as you thread it on, it opens the valve up, they are crucial with nasty diesel oil. Not gonna lie, watching you take an oil bath had me laughing! Great video!

As mentioned about keeping the engine clean, there is an access cover on the side of the engine to clean the cylinder liners . Secondly Always keep a spare fan belt as they take a lot of abuse . Also, ALWAYS ALLOW THE TURBO TO COOL DOWN AFTER A HEAVY USE ! you should idle the engine at least 5 mins .Always change the inner air filter with the outer .

Our obsession with lawns has reached the point where we now buy excavators to remove boulders

as a German and a mechanic, daily working on excavators and sometimes old Deutz motors this video has me smiling. keep up the good work you have a very reliable machine there

I am an old Diesel guy, heavy duty lubricants guy. Story: In 1990's on Long Island, an air cooled Diesel same as yours in a rock crusher was turning motor oil to tar. They first blamed our motor oil (of course) we went out to have a look. We found that the plasic blade cooling fan had passed so much grit-filled air that it widdled down to nothing it no longer passed much air and the engine was toasting it's oil. (Before hydro cracked base stocks I guess) So, have a look at your cooling fan and make sure it is good as new. Maybe depends upon the region. The ducting/sheet metal shroud is also very important to force air to coolers. Don't let anyone run the motor without it. Seal any gaps to force all the air through the coolers. Also, feel the exhaust manifold near each cylinder during a cold start to see if all reach temperature similarly and you can tell allot by that. New hydraulic fluids are better and so are greases. A good moly or graphite grease matters, high tack helps too. Seal conditioners in some hydraulic fluids can help restore valve seals and piston seals. Tranny fluid works pretty darn good too. Some folks even use motor oil in the entire machine. Manufacturer has recomendations but those are long outdated. Synthetics are a great way to go whenever possible especially in a machine that sits. Keep a 55 gallon drum of hydraulic handy. Also order hoses ahead of time, maybe learn to make your own. Check any rubbing points. Make sure you reinstall clips and isolators and and ad if you have to do any wiring. Anything touching the motor or frame can be short lived. Diesels will vibrate through wire insulation, hoses and fuel lines quick. Thats why so many clips on those fuel lines, there for a reason!

Where’s part 2?

When you change out the teeth. You aught to consider hard facing the side of the bucket. This will help give longevity to the bucket, and it’ll give you another skill in welding. Plus with all the rocks you’re going to have to move it’ll certainly keep the bucket more usable longer. There is actual hard facing welding filler, but I’ve also seen folks just use a standard 70 series rod/wire. Hope this helps! Love the video

Name the excavator Hans, because Liebherr was founded by Hans Liebherr in 1949. Greetings from Germany. Btw love your channel.

Hey so I’m a apprentice in the heavy duty mechanics field in Canada and whilst I mainly work on semi-trucks one thing we learned in class whilst learning about tracks and undercarriage for equipment such as yours is that it’s a common misconception to dig on the side as you were. The machine is actually meant to dig from right on top of the front idlers. Whilst you can’t do that in every situation and I’m not bashing any operators who do dig that way it’s been proven to accelerate wear on the undercarriage components such as the bottom rollers and sprocket. Just good for thought. Cheers

Great video! Looking forward to part 2!

Luv the video... Cant wait to watch part 2! “Big Bertha” or "Fritz Vator" are 2 names that come to mind.

Word of advice, when prying on big rocks always try to keep the bucket on the ground and pry by curling, prevents unnecessary strain on pins and is easier on the machine, absolutely loved the video 👍

$7500 for a running machine, no matter the size, is amazing. I'd have expected bad engine, failing hydraulic pump, cracked boom, and a half dozen other issues for that price.

Good that the parts are still available, and the machine is of a vintage that doesn't get obsoleted for lack of electronics and software :-)

Hanz for sure. Very entertaining especially because I’ve never watched anything like this before. Thanks!

As someone who’s been around large equipment all my life I can say you are doing exceptionally well for your first time👍🏽

Because of fluid mechanics (of dirt lol) that boulder will rise back out of the ground over time. I would recommend moving them rather than just reburying them. or put them a little deeper into the ground.

I use to work at liberty international in Manchester, those valves on the oil pan are called no spill, you can get an an adapter and a hose that will plug right into that fitting, presto no mess. I use to sell those things.

Thanks for making this video. It was very informative.

Whenever you can, you should dig with your tracks in line with where your digging with the track idler's in the front. Wont wear out your tracks and sprocket as quick. Happy digging from the 603 aswell!

There’s nothing quite so satisfying as taking something that is old and needing work, and fixing it up to workable condition again. Great video!

What an awesome video. My eyes were glued the whole time. Instant sub.

When is the part 2 going to come out?

I am 74 now. As teenager i was equipment operator an did some repair. When in my mid twenties to mid thirties, I was a heavy equipment mechanic. I bought several pieces of heavy equipment and repaired them. Wonderful hobby, repairing my own equipment. In mid thirties I realized it would be very hard when I got older it might be too hard to continue. I went back to school and learned computer programming. I retired with twenty plus years in computer automation. Since my retirement I learned to buld apps. I freelance now.

A bit of advice, when excavating something as large as a bolder have your track facing it straight, and not sideways with it, you can tip over an excavator that way, it jumps a lot and, also, the idlers to the back to keep the weight behind the machine. PS: Just noticed that the excavator is also leaning towards the bolder as well on a slope which makes it even more prone to tip over or bounce a lot Happy excavations to you, these are fun to run...

5:50 Geez, that really puts it into perspective the size of this unit. So far, it looks like you scored on this one, no blown hydraulic lines or other obvious major issues. I'm used to seeing the stuff Matt (channel: DieselCreek) buys. I really like the metric units you add to the video. So I was right; it is turbo charged. I kept hearing what sounded like a turbo every time you stopped moving the excavator.

Two Tips: 1) get an electric grease gun if you don't have one already. I know Milwaukee has two different ones. I assume most other companies like DeWalt and Riobi probably have them too. 2) You should look into selling the rocks. Where you live everyone has them in their yards, but in other places that is not the case. I live in South Jersey and it's flat and rockless, so if we want rocks of any size we have to buy them. Just something to think about.

Yay Deutz! My late father was the second Deutz dealer in the US! They can use 10-15 seconds of glow plug pre-heat and will start instantly regardless of temperature. Use a pressure washer (or steam washer) to blast off that buildup. The 913 deutz engine line is ultra reliable and can give you 40,000 hours of use if you keep it clean (cool) and feed it clean diesel fuel (good filters). I had one irrigation pump that I overhauled at age 18, and many years later, the owner brought it back with over 50,000 hours more runtime... The big air pre-filter can be cleaned by tapping it on the sides on a flat surface. Rotate it around, gently tapping the filter on the surface.

Great video. First time watcher here. I’m a heavy equipment mechanic in MD. If I could give you one piece of advice whenever digging especially something hard like a rock position the tracks so you are digging over the idlers and not the side. You don’t want to dig over the final drives (planetary gear boxes with the sprockets) because that shock can hurt the bearings and gears and they are not cheap. Keep up the good work

Super clean in a sprayer and a pressure washer...did this on a 1953 ford NAA tractor before painting. Works good.

Thank you for showing

I use to be from NH built in MASS, Excavating contractors use to give estimates off of the site plan for septic, material needed, stumping, cella hole and back fill, utility lines, driveway, basement prep et-cetera. The only additional would be the unknown boulders over a certain size and if ledge needed to be blasted out. Then someone somewhere somehow started the idea of " Hourly rate per machine plus trucking." Tried another contractor and realized it was the "New norm". I once showed up on a job to meet the operator, 7 am as we drank our coffee (pre-cell phone days) we went over what needed to be done. I left after about 1/2 hr (hr meter running while machine warmed up) and an hr and a half later forgot to mention something so I drove back he was still in the same place talking with another contractor that was working next door still drinking coffee. That was it for me besides. They also charged per yard for material and for kicks I calculated a dropped load and low and behold short of what I ordered. You never got what they charged. I once mentioned, pissed off to one site contractor that I was going to buy my own machines. His reply HA I would not. Do you know how much the parts cost? So I did what you did I found an old Hitachi ex-120 Had no clue how to operate it and figured I made a mistake but I stayed with it and in 40 hrs I was efficient and confident enough to have at it. Your machine can pay for itself in a week. Great job great vid.

I'm not exactly sure why RU-vid recommended this video to me, but I LOVED it and can't wait to watch more videos on your channel. I think the last thing I needed was another channel to be obsessed with, but here we are!

Good buy! Sounds great. It will really co.e in handy

I would definitely use some kind of engine flush or atleast a bittle of mystery oil to clean up everything inside the motor thats sludged up. Mystery oil helps so much when it comes to cleaning sludge and stuck lifters.

Waldo, please install some plexiglass or wire meshing between you and the material you're handling. That thing has a lot of power and if some of the stone breaks off, the chips could hurt you. At least use some glasses. A friend of mine has lost an eye using digging equipment. A small metalic chip broke of somewhere and screwed up his left eye for good while working with the windshield open and no eye protection. Don't take it the wrong way, just a heads up, can happen to the best! Good buy, have fun with it and be safe

Always worth running drop of oil around the seal on a new filter, and don't use the filter wrench to tighten the filter - you can see where you damaged the new oil filter in the video!

Love the video and instruction. Marvin❤

Theses are all over the place in Québec. Since the frost line is 4-5 foot deep, we need to move a lot of dirt when building of updating water and sewer pipes. There's also the fact that the Canadian Shield and the Appalaches cover most of Québec. In my area, there's rock outcroppings all over the place. If you dig 5-6 feet deep, you are almost guarantied to find rock. Most construction compagnies have a hydraulic hammer lying around on most jobs and having a big machine to run it helps a lot.

Nice work, good machine. You’re gonna want to make sure the top of the bolder is at least four feet below the surface below the frost line. We have a saying in CT, rocks grow best. The water gets below them and freezes, then pushes them back to the surface. I cut over 100 trees in my yard, about 36 of them were between 100-125 feet tall. Stumped it all out to make a field, and all the boulders I left in the soft soil I disturbed have poked up to the top. Also learn Fromm your mistake and try to keep your top soil and fill in separate piles when you dig the holes so when you fill them back in the top soil remains for grass to grow

I just came across this video and it is the first video of yours that I have seen. I own my own excavation company and can tell you that a hot bath is not necessarily the best thing to remove grease. If you get a pump up pressure sprayer and put diesel in it and spray the entire tractor off with diesel, it will remove the grease instead of spreading it. If you repeat the process twice, you’ll be pretty clean. Hope this helps.

Fellow New Hampshire resident too!

I only wish that i had your time and patience, congrats on the find!!

Congrats on the machine! Liebherr makes great equipment. Just note that those should be ran at high throttle to get the fan to move enough air to keep it cool. 👍

Here's a tip for oil filter change with less of a mess. Once you get it turning put a plastic bag over the filter then unscrew the rest of the way with your hands and work area protected from any spills.

the oil bolt has a no spill you can attach , also when i was an apprentice fabrication engineer i made a aluminuim box funel with 1and a half inch pipe for runnng oil straight in the waste drum which either bolts on or uses rare earth magnets depending on acess!

You should keep the boulders for landscaping instead of burying them. Always enjoy your videos. Hopefully we get a part 2 follow up.

Those Deutz air cooled units are great engines, easy to work on, But replacement parts are vary expensive so take good care of it. I worked for Atlas Copco Wagner Mining Equipment Co as a diesel mechanic for 18 years and we put a lot of Deutz engines in our machines. Those batteries you used should more then ample in that machine, no need to upgrade to the larger battery if everything works fine. Also the next time you change your oil you can install a remote oil drain on the engine, simple to do, we did it all the time on our machines for that simple fact. Also you can steam clean or low pressure power wash the inside of the engine to keep clean the oil coolers that’s important. The oil is the life blood of the machine. While I’m talking about oil have you heard of IXL Oil Conditioner products???, I’ve been using this brand for over 30 years in my personal gasoline car engines, axles, transmissions. You’ll have to go online to the IXL store or maybe a diesel truck shop. They have a great line of products. You might want to install a oil temperature gauge and maybe a pyrometer gauge in the future. Also if and when servicing the hydraulic filter and system when refilling and I’m not sure of the hydraulic system design but pre-fill the hydraulic filter so you don’t run the hydraulic pumps in a dry state on restart after service. Then when the machine is not in use have the boom n bucket in a down position that all the hydraulic cylinder rams are retracted into the hydraulic cylinders to protect them from external damage, you don’t want to have to replace one, Probably over 1,000.00 dollars. The big thing to remember is if you break something on that machine you could be easily over the original price you paid for the machine, just don’t do anything stupid. Happy digging👍👍

the only issue i see with burring the rock is the frost pushing them back up.

Nice insight! I'll probably never need one but it's nice to know there are working models for the price point.

Having run a variety of Leiberr's from 912, 942, 952 to a 972, they are great machines. As somebody already mentioned, keep the engine free of oil and dirt.

I like Hans as a name! And if you ever get a small excavator of dozer, you can name it Franz. As for the way it operates, it sounds like it's really laboring when you use more than one function at a time. That is usually from clogged fuel filters, so hopefully when you get the primary filter replaced, Hans will operate smoother.

I worked at this type of equipment for my fathers farm and wold make one comment when dealing with older stuff like this. We bought a steam/ hot water power washer and it changed my life. The accumulated oily grime that infests every inch of machines like this can be cleaned off with relative ease making working at them a much more pleasant experience, it also reduces the risk of grit and grime getting into important parts during maintenance and helps stop you getting a thick coating of greasy grit on arms and face. Nice machine looks like it will respond well to a little care. One other point check all the major hoses and replace any sketchy ones before they let go on site, it can save aeges of wasted site time.

That's one of the most wanted and awesome versions of this engine. Well done.

Very cool best of luck thanks for the video!

Hey Waldo, I like your show and admire your skills and guts to tackle big jobs. One tip, tie shop rags around your wrist's to stop liquid from going to your armpits during overhead service. LOL. I really like the projects you share. Keep up the great work.

That engine is a gem. Had an old worn out one back in '95 used in a scrap yard....got that 6 pot air cooled diesel running a treat......tighten heads...they work loose and reset tappets.....easy! loved it

did learn alot by watching 🙂 looking forward to part and what they found in that old oil that you send in for a test.

Who do you use for your oil analysis? and what are you looking for on first one. I drive semi. I see getting analysis over many. I started doing on my truck when I bought it. I use Blackstone.

What about part 2? When will that be released? Really curious how it performs after some time... and the lab results of course!

Tip on that oil drain plug: Install a short hydraulic hose with a valve or a hydraulic coupling at the end. This will provide better control when draining, and the latter option gives you very low spillage and also provides a way of draining into a sealable container.

Approach with he tracks facing what youre digging in, not sideways. An excavators power is in the bucket when trying to move something big and heavy like rocks curl the bucket instead of pulling the arms up. Once warmed up keep the throttle at or near 100%. Give it a litle while to cool down at idle speed when youre done. Its nice to see someone admitting they dont know how to something. You learn by making mistakes too. I had no idea these things could be so cheap but theres an auction near me im going to have to check out.

Is there a Part 2 to this video? Looking forward to it :)

Definitely check out your hydraulic system, check level and strainer/filters Tighten the tracks, not overly tight but those are pretty loose. And the exhaust dumping in the engine compartment will cover everything in soot, any work you do and you’ll look like you just clocked out of a coal mine. You seem competent enough to just make repairs there so that will save you on parts. At the end of the day it’s just a machine if you keep up maintenance on one they tend to keep lasting, try not and side load your boom where you can help it, excavators are the most powerful in a dig to you motion around a 90° boom angle but as an operator myself you’re not bad at it, Smooth is fast, even it it doesn’t seem like it. Reduces wear and operator fatigue over bouncing around. Just remember the farther you are out the less control and power you have. Grease it regularly and keep the fuel tank full to lessen tank rust and moisture buildup in the fuel and the experience will come with hours put in. It’s always fun to see what Waldo is working on. ✌️

Tip: you crushed the filter while tightening it with those pliers. In fact oil pressure is not as high as you may think(cat c15 manual says dependent on rpm between 40-80 psi). This means if you have properly cleaned and lubed the surface of the filter and the filter housing, hand tight is usually enough (depending on grip strength). If not a filter socket or the metal band style filter wrench are best. Pliers are for taking off not putting on.

Waldo I don’t know if you will read this but man you sure know a lot about everything !!! You don’t find many that knows how to fabricate and mechanic, weld and rebuild just about anything!!!

Liebherr crawler excavators are made in Colmar, France, not in Germany. The Deutz engine which powers this excavator, was made in Colgone, Germany. So Gustav might be a suitable name as this name is used in France and Germany.

You got one heck of a deal there Waldo, Beast mode love it. Otto is going to look great with a new paint job.

the tool you used to remove the old oil filter is only for removal. Using them to tighten a oil filter can damage the oil filter and cause it to fail. there are other tools specifically made for the thin walled oil and fuel filters. that evenly grabs all the way around the filter helping to prevent damage from occurring. other than that even those are not required due to oil filters being perfectly fine hand tightened. (Not a weak hand tight, tighten it like you would a 2 week old carton of spoiled milk that you can still smell when you close the lid so then you go a little more.)

Bertha. Call it Big Bertha. I like your video. You did a great job getting her ready to go and I thought were pretty smooth on the controls.

Suggest changing hydraulic hoses as a preventive measure. You do not want a breakdown in the middle of a project. Check hydraulic pumps , final drive on tracks and transmission.

Nice machine! Lots of iron for the price. When you’re digging something like that out, try to do it with the idlers facing the rock. It’ll be a lot more stable and you’ll be able to put more power into what you’re doing!

Great video. As a general rule, always dig over your track idlers. It is the best for the track frame and final drives.

Man what a great video. Good job.

Fantastic, high quality video.

All Liebherr machines have this type of "valved plug" on all their oil drain locations. You need a special Liebherr tool fitting that comes with a piece of hose, and when you tread it to the drin valve it opens the poppet inside and allows to drain the oil through the hose. Is a must tool if you own any Liebherr equipment. Ask your local Liebherr dealer for it, the oil drain adapter and hose.

Been running excavators for 20 years and you did very well for your first time .. you'll be a good operator because you're pitcular and pay attention to fine detail 👌 keep it up!

I'm loving the mental image of an operator getting frustrated with the seized throttle lever, putting more and more force into it until it just snaps off with them holding the broken piece up with an 'ohh shi-' look on their face lol.

In Bradford, we took the stones out of a two acre pasture. We were able to build a stone wall four feet high, four feet wide. The wall went atoung two thirds of the pasture.

Check the grease fittings, you will need a grease gun and probably around 5-10 tubes of grease to make sure there is no metal on metal grinding on the machine.

South western PA equipment tech here. Those are the best damn engines you could ever ask for. They are almost bullet proof. Soooo easy to work on. The only thing to watch for is the timing belt. They are interference engines. If the belt breaks or slips it will bend every push tube in it. However, still super easy to change because it’s oil cooled! No mess taking the head off. P.S. that Stauffer diesel that rebuilt it is the authority on these engines on the east coast. If they don’t have the part, it doesn’t exist. Good luck man. Enjoy

One big issue with those Liebherr classics before the Litronic came out is the hydraulic oil cooler mounted on the top and filling with dust and dirt along with leaking oil. The hydraulic system runs so hot that they leak like crazy and the hoses don't hold up. Very problematic if run steady. Parts are very expensive if available, especially from Liebherr. There is a guy in Erie Pennsylvania that sells reman pumps etc for many of them.

Fun video! Thanks!

Hello Waldo, I've scanned a few comments below and I'm just going to dump on a few more. 1) that's a hydraulic machine and needs more throttle. 2) bury the rocks deeper or you'll be seeing them again. 3) suggest buying a few hours of an experienced operator's time to give you some training. That thing is large enough to hurt you and break things. 4) keep an eye out at auction for another bucket. Might be cheaper than any repairs. 5) another reason it was cheap is it has no "thumb". 7) buy a big pressure washer. Spend a day washing that thing down. The next day, do it again. My experience is that the third time you will still find major dirt. A clean machine will much more pleasant to work on when you have to change hydraulic hoses. I have a BE 13 hp., 3500 psi, 4 1/2 gallon that works great on big iron. A clean machine also makes it easier to spot cracks, loose bolts, and other broken stuff. 8) put money aside. Hydraulic hoses aren't cheap.

Been away from the excavating for many years, but after 30 yrs owning I suggest 1) grease every fitting regularly and replace/repair any that don't accept grease (sometimes just raising to remove weight from pin hydraulically will allow fitting to accept grease 🤞, other times untreated impacted grease/dirt requires pin removal) one reason it's inexpensive, but you did a good buy it seems. Many experienced responders on here. 2) I don't think new teeth are a priority (won't help) for your application as long as they aren't worn through to the shank inside tooth. Your smaller backhoe loader will level up and grade for you once you get the touch.

You're funny. And being that you rise in my esteem, because you are not afraid to show. In this respect you are at the same level as Diesel Creeks Mat. Good work.

Hell of a buy for the money!! I was looking at old backhoes that cost more than that. Need one of those on my farm! Gunther or Fraulien is catchy😮

Since the cab doesn't have any glass on it, unless you've added it since this came out, it would probably be a good idea to wear eye protection along with your hearing protection just incase a shard of rock gets launched at the cab when you're digging.

Oil filter installation tips, wipe the o-ring with fresh oil and install by hand, only use your hand to tighten the filter. Never use a wrench to tighten oil filters. You can bind the o-ring and ruin it causing leaks. Also if you get lucky and don't ruin the o-reig they will be over tight and much harder to get off the next time.

This just came up on my recommended and loved this video. I want to show my nephew. Very surprised after 10 months no update. Giving a follow so i can get an update.

Hans is an excellent suggestion since Otto sounds a bit corny. I agree with the previous entry about Hans Liebherr founding his company in 1949. Since many people don't usually just go out and buy an Excavator, and you have a wonderful piece of property, preserving History, in your equipment story, may be helpful! Tip:. An equipment diaper is available to attach, with strong magnets, to the area under the access hatch - to your Oil and Water separation filter area. It will keep the filth contained in this spot below your engine - so that you don't get dumped upon, in the future, when doing maintanance. Excellent video!

1. How much per mile did it cost to transport to your property? 2. What was your “pre-anticipated” budget for maintenance and servicing it for the first time? 3. What was your total on replacement parts? 4. What preinspection have you done before bidding? 5. What happened to part 2?

If you live in an area with underground frost during winters and bury boulders back into the ground you should ensure that the entire boulder is well below the depth where the soil still freezes if you really never want to see it again. I even a tip of the boulder is in the soil region which freezes during winters the frost could proceed through the boulder and start a pumping action below the boulder, rising it by a very small amount every winter. It may take many many years but eventually a hump starts to appear on the lawn and then finally the boulder is revealed.

not a heavy machine guy but reallyyyyyy enjoyed your journey with your boulder issues..just curious what the charge was for transport?

Those boulders are fantastic for landscaping! They are 10 cents a pound here in Los Angeles. My heart sank when that BEAUTIFUL NATURAL SCULPTURE WAS BURRIED! I'll give you 5 cents a pound for it! Love your channel. : )

Man, I thoroughly LOVED this video you made! You were humble enough to show your oil change goof and to admit you were an inexperienced operator. But you showed all the common sense steps from initial transport prep to actual transportation which was really interesting. Although I am curious how much these oversize and overweight permits ran you plus delivery costs per mile. I think one other problem you'll run into sooner than later will be finding industrial replacement parts for this 1986 LIebherr 926 excavator. I sure hope you post more videos of GUNTHER. Yes, in Deutsche, “hard, strong man" is befitting this 40-ton beast.

Going round in circles is known as slewing, curling the bucket in is crowding and the short piece is the dipper, the next piece is the boom connected to machine at the boom foot, hope you have many years of hard work and pleasure from your purchase. When moving a boulder of unknown size best practice is the tracks pointing at it not digging over the side like you were, happy digging 👍🏻🏴󠁧󠁢󠁳󠁣󠁴󠁿

liebherr was and is mainly a rock quarry demolition scrab yard machine is where they specialized the most they put the valve on the oil Incase the pan and first bolt get knocked off it was there attemp to stop the oil from pouring out

I live in NH too and removing rocks is always a pain
