Hi, Folks. A grader will do a LOTTTT of the work for you if understand how it works and let it 'do its thing'. What do I mean by this? A grader works on 'the law of the lever'. If one front wheel goes over a rock 1 foot high, that movement is halved to 6" by the time it gets to the center of the front axle, It is halved AGAIN, to only 3", by the time it gets back to the middle of the blade. So. if you don't do ANYTHING, all you are going to have is a 3" bump at the middle of the blade. Go back and do another pass on that same line and you will reduce the bump to 1 1/2" to 3/4" of an inch. FIND the bump. Have you ever heard anybody else describe operating a grader thataway? Operating a machine, any machine, earth moving or otherwise, is ALL about being able to THINK the machine, understanding its capabilities AND its shortcomings and being able to set the machine to get the best possible results. In earth moving, that means being able to set your blade/bowl/cutting edge/bucket to take the material from where it needs to be taken to where it needs to be placed in the condition in which it needs be when placed with the least possible number of passes and the least possible damage to the machine and the environment in which you are working. Where the REAL skill set lies in operating a grader is partly in being able to set the machine to achieve the desired results and partly in understanding the materials with which you are working and how best to handle them. It is best to remember though that, unlike most other earth moving machines, a grader is a 'finishing tool', more of an 'instrument' than a 'brute force' machine like a bulldozer. But what would I know? I'm just an apprentice - - - with a mere 58 years in the saddle on most types of earth moving equipment. I'm still learning. Just my 0.02. You all have a wonderful day. best wishes. Deas Plant.

I’ve never reversed Down a steep pile with a load. I’ve never felt nervous driving down a heap. Most of the time I’m going downhill empty anyway, but the bucket In front of you gives you stability. You can always drop the bucket to the ground if you start sliding or something.... even tipping the bucket back out and pushing your way down the material making a new ramp as you go. I’ve never rocked the bucket when loading the bucket either and never locked the lift lever in when going into a heap. You should be able to approach the heap, lift slightly and crowd back while moving forward all in a smooth motion and getting a full bucket. All those jerky movements just throw you around in the seat. I guess it’s the difference between being taught by an instructor, and being taught by an instructor that’s spent time actually operating them for a living first
But experience operator teache me Bucket level may be bucket edge plate well damage he though me this we do it again and again He told me to open the bucket little bit And make take the cargo
You might want to add to shift into first gear when you have a load on the front tires, so you dont overheat the torque converter and transmission in 2 nd gear,,, You will burn it out 2 nd gear is not meant for filling bucket pushing into a pile ,,, look it up in any owners manual.
Hi Peops, I'm just a regular guy who takes an interest in all things that's machinery related, in esp.vehicular prime movers of evry types. To all U Guys who work these Loader things like maybe day-in - day-out & knowin' 'em practically like as-if they were the figurative "Backs of Yer Hands" adage, I suppose it's safe to say. There's this 1 question that's been gnawing at me all this while & I've been meaning to forward this to all U Guys who is in the know. Why do Loaders of today or recent makes, all have cabs that sit with the engine on the rear segment of this articulative-steer system ? From what I learned, it seemed there was a certain survey held, some time way back in the 70's for the specific purpose of finding-out wic of the 2 segments, operators as Yerselves, wud rather the cab be on & Yor predecessors of that time by a majority, largely favored having the cab placed at the forward segment. So it then came to pass & was for a time thoughtful Wheel-Loader manufacturers then built quite a number their product based in accordance with that decision, with the likes of International Hough Loaders. I thought the same with likeminded loader-operators, the cab shud somehow be with or on the front-section of things, but it now seemed that that was not to be & that design had totally been altogether abandoned. I hope summa U pros in the know, who so happen to read on this article, coud maybe enlighten me a little on the pros or cons of why it is or not better for the cab to sit on the forward section & share Yor opinion on this subject. Please allow me to Tnk U Guys in advance fer yer time & attention in reading this commentary. Ave a good day or a nice evening ahead.
When the cab is on the front of the machine you then have to have a lot more hoses and wires going from the engine compartment to the cab and such. With the cab behind the articulated part you'll basically only have the 4-6 hydraulic lines that need to cross the articulating section.
Its called submarineing aproce pile as bucket arives at pile roll bucket out diveing (submarining bucket and as result filling buket to capasity faster
The loading method is wrong. Lift the boom a little, then start to curl the bucket. Depending on how hard the bank is, you may curl all in one step, or curl, pause, and then curl some more, repeating until fully curled. You may also need to continue raising the boom, but it depends on the material. NEVER "pump" the bucket by going back towards level. This unloads the tires and creates wheel spin, as well as unneeded wear and tear on the loader. Locking the boom in raise takes power away from the tires. In soft ground, you need to do that. On a hard floor, you need the power to drive into the pile, so that is why you don't lock it in, and pause in the curl, to drive in harder, but curl again before you get tire spin.
Some materials you have no choice but to pump the bucket to get a good full bucket without taking forever. And if you let of the throttle while"pumping" the bucket you don't get wheel spin and it's not violent.
Noel is correct in saying that this video is teaching incorrect procedures. One should never "pump the bucket" as stated add this puts unnecessary and damaging force in the front end of the machine.
If you want a stock pile just dump and create a ram .Lifting a loader bucket up full takes time and danger .Plus loose material now and then if the heap is set .It makes for easier bigger scoops .Don t forget the knocking the loaded bucket before travelling to avoid dropping material on bumps .
