Pulley Swapping a Hydrostatic, How Fast? 

the reason they say you cant pulley swap them is because the pump in the trans will burn up, killing the trans for good. Good test though, I didnt think it would go THAT fast. Pretty cool!

10 mph is impressive! And it's a good mudder!!

racing lawn mower - the most senseless hobby I can think about wasting the free time but - man I loving your channel for this exact thing 🙂

Pretty good,quick build. I always forget the lever that releases the hydro too 😂. Most hydros whe water is deep enough for the fan to contact water....the fan blades act like a propeller slowing it down and making slipage easier. I trimmed the blades down on my old husqvarna,it helped but still slipped when water got over the fan.

thats really good for a hydro, i put the belt on the deck pulley on mine and did about 8 mph

Thanks for another video!

Great job 👍🏻 👏 👍🏻 👏

KEEP IMPROVING THE UPGRADES.

That mower would be awesome with a Lift kit Straight pipe And truck tires I might try to pulley swap my hydro just for laughs

Hey! I think thats my old mower! 😂. It's about time you did something with it.

I really really like your videos

Can't wait to see a video on that soon I wonder what happens if you pull swap a hydro

Awesome test run. I have been wondering about the hydro pulley swap. Good to know it does work. I wonder if the engine had a little more power if it wouldnt bog so bad but may could get some more top speed with a taller tire too. guess we will see what the longevity will be. thanks for the video!

Very good video thank you for the video

I’ve put some amount of thought into pulley swapping a hydro. The limiting factor to speed on a hydro is the maximum flow of oil in the transmission, which may or may not be achieved above the stock pulley setup. If you pulley swap it too high, you are achieving maximum flow at a lower engine rpm- giving full speed at lower engine power, causing it to bog. Give it more throttle in that situation and you don’t gain any speed, and only make more heat because the trans is trying to pump more fluid that it can use. If you can find the max speed that the hydro will do and tune your pulley swap to make that max speed at your engines peak power making RPM (usually the governed 3600), you will be be able to use your transmissions best speed, at your engines best RPM, and hopefully without overheating your transmission. Hot Lap Garage on RU-vid has several hydro Wheel Horses, they are stout units and proven to be very capable in rock crawling, even placing well in TTC. I saw his Ghost pull a dead wheel horse up a crazy rock crawl. He’s starting to have problems with them overheating and I believe he’s planning on installing a oil cooler on one. Hydros are something that I think need more research and trial and error!

I pulled swapped my 20 hp briggs vtwin wizard its hydrostatic and that thing moves pretty good. Haven't had any issues with the trans yet . It does get pretty warm if your running it hard though so it might end up taking a shit at some point.

Pretty darn cool.😎

my new build is a 1972 Massey Ferguson Hydra speed. It does 13 mph Stock in high gear, I am putting a Kohler Command Pro 37 HP on it and building it as a tractor recovery rig...

Pulley swapping a hydro overclocks the hydraulic pump in the transaxle. You get more hydraulic pressure at the expense of more heat and fluid cavitation.

Awesome build chud, i got my 21 hp briggs in my mower, but i got a flathead 10 horse that i could swap on there to do this swap, still need a pulley for the rear end. I think also if you used i think transmission fluid, you'd get somewhat better cooling, cause the heavier gear oil heats the transaxle really bad. at least, so i've heard.

The key to a fast hydro is using a live axle and sprockets on the axle shafts of the hydro to changing the gearing. The bad part is engine braking/slowing down, not sure how the pump would react to that.

I have pulley swapped several hydros and never had a problem with them and I have a pulley swapped Mud Mower Hydro that goes 14 mph

I especially liked the part where you thought it was an atv:)

Cool, I love your video, I'm only 15 but I love tractor mowers and I love riding tractor mowers and if I had known you in real life, I could have ridden your tractor mower with you.

Looks like it'd be a good Wheely machine. Like standing still with the forward and reverse

Almost took out the angle grinder

westport wa.state here and listening watching and learning sir. thank you for showing me that. if i get in that situation next summer. do believe i will put a hole in the bottom of the tranny. in line small pump. and get a small cooler. sure something for me to think on.

Idk it might blow it might not btw chud I love your videos

Hey chud. I have a 2005 Murray mower I was gonna swap I plan on putting a 2inch on the transaxle and do the pulley flip locking nut trick on the front. On the transaxle should I put gear oil in it or run it like it is? because they come stock with grease and I dont think that would be good for higher speeds

those wheels at 9:46 could be some big front wheels for something like major dan whenever it gets rebuilt

Heyells yes nice. What do u think would be good replacement motor for cub cadet 2542 with locked up Kohler command horizontal shaft. Try get this one i got for my pops to cut grass with. Hes getting up there in age andhes one of them guys that's gotta be doing something so you cant even cut ot for him he'll do something else.lol so minds well get him on a rider. Our ole huskee is about on last cut. And that was few years ago. I got nice cub looks new was always cleaned after it was used and has captian seat atm rest and its not cracked. Lol. Thanks love all the videos had to resub my phone been acting crazy. From ur ole hillbilly buddy stay safe.

Im building a murray pulling tractor for rc track maintenance will 20x10.00-8 fit on a 8.00-8 rim i got clearance between back sidewall 20x10 tires seem more available and better tread options. Its hydro auto but im dragging stuff behind it so no pully changes for me but a 11 mph lawn tractor would be cool i definitely think my 14.5 briggs would move but don't want to hurt the trans shes a old murray from 96 so im sure parts are hard to come by

That’s cool! I was always under the impression a hydro can’t be swapped because it’ll burn up. Do you know what company manufactures that trans?

be curious to see how long it lasts. i did this a while back ago with a wheel horse hydro i built for my sister (so she didnt have to having to worry about shifting). she ended up sinking it up to the rear seat and blowing the transaxle. ended up having to leave it. it ended up raining and where it was at it got fully submerged and that was the last i saw of it. so long story short im curious to see how long yours last. that one lasted a week and it was a more beefy mower, it also did about 10 like yours.

So this is the first mower that you put a pressure washer engine on?😊

Is the 18.5 Briggs good on a mud mower mine has one and should a straight pipe it?

My wife has 2 j.d hydro mud mowers with 26 inch atv tires thay will do 12 mph she has run them for a year no problem

I just got a craftsman ys hydro drive lawnmower and work on it to get it cutting grass again

Are you going to try to put a zero turn rear end on a front of regular mower

I didn’t know hydros could be swapped

Ee erre eee errr eeee errrrrr eeeeee errrrrrr eeeeeeeee errrrr eee ehhhhhhh. Gold

Have you ever used a pressure washer engine on a mud mower before

Are bed frame great for wheelie bars

2 things, bigger fuel tank and a cab! is that possible and are you planning on it?

DUDE I LOVE THE VIDEO AND I REALLY LOVE YOUR TRACTOR OR WHAT I DON'T KNOW WOULD IT BE CONSIDERED A TRACTOR OR LAWN MOWER I DON'T KNOW CAN YOU I DON'T KNOW MY BRAIN IS JUST MESSED UP BUT GOOD JOB LOT LIKE HEY AT LEAST YOU DON'T HAVE TO BUY LIKE A 1 MILLION DOLLARS TRACTOR

Everyone wake up daddy posted 😍😍

moin wo hast du die reifen gekauft ????

I really want to see this mower do a sand test? Sand test coming soon...?

How’s the weather in Florida??

What are the best tires to get?

How is that mower going

👍

👍👍!!!!

"slitly metric" 😂

i'd like to see electric motor say from golfcart on mower curious of the speed would be like.

At 9:02 it was a cold start but you can see the frame switching 🤣

Chud, this is a joke but if someone wanted to by everyone of your mud mowers what price tag would you put on all of them together? 😂

What happens if you pulley swap a hydro

Is the trans still ok 😅

#TRUFAN

It would of been faster if you would of put a more powerful engine tbh but thanks for proving haters wrong

How are you 😊❤

that might be " slightly " , metric ? .. Either it Is , or it is Not

i understand the test but not the way to do it... it could be so much easier!

Doesn’t make much sense as to why you would swap from 18 horse to five and a half.

just buy an ATV

Silly 🙄 buy an atc boy

10mph is pretty impressive for what it is!

Is the trans still ok 😅
