Tires do not spin

[3gunr]

It should spin those tires in low, My 2538 with loaded tires will spin on any surface other than concrete, I dig a lot of dirt repairing our creek crossings.

The good news is it is best not to spin the tires. When you spin you lose traction and that is when you get stuck. As long as it pulls what you need it to pull probably is not a issue. But I suspect pressure is low. Might get the service manual and follow the directions for checking pressure on the HST.

I believe your tractor is "broken" From what all you have said, and I read it wont even spin the tires in low range on dirt in 2WD. Your tractor needs service. Take it to the dealer and have pressure tests done on the hydrostatic transmission.

My Kioti will spin the tires on a loose surface (like your dirt) in low OR medium range. Not in High range. And that is with loaded tires, and an 800+ lbs ballast box on the rear.

It just bog's down and doesn't spin

No squealing from hst relief valve. It will not spin at all. Rpm from idle to wide open. It's the same no matter what I do.

What exactly bogs down? Does the engine load up like it's going to stall?
How old is it? Did you just get it?

I've had it about 2 months it's about 4 year's old. It doesn't load up or stall it just stops moving forward..it will stall out if you hold the brakes.. 330 hours.

Boy not for nothing but is it possible your rim is spinning in the tire? This does happen and has fooled quite a few people. Maybe mark the tire and rim try to spin the tires and see if the marks move.

Yep, this fools quite a few people.

I forgot about that. That is an excellent idea, especially if his tires are loaded with Rimguard. That is slimy and if you don't have enough air in the tires the wheels can spin in the tire. I guess we have established that nothing "bogs down", in other words the engine RPM does not decrease to the point of stall. TO the OP Words have meaning. Use more of them to describe your situation and be precise as you can. This will help us understand what may be wrong. So if the engine does not stall, and you seem pretty sure the hydrostatic transmission relief valve is NOT opening, then it must be something else. And the wheels spinning in the tires is certainly a possibility. Please also if you do find and solve the issue, come back here and let us know. Thank you in advance.

Thanks to all you folk's . I will try the rim spinning theory

 

[JoelD]

Odd it will stall with brakes and not under load with no tire spin. Rims spinning in tire sounds like it would explain it. Any other reason why brakes would stall machine and load would not. Wouldn’t relief valve kick in regardless to avoid stall?

Rimguard has shown to be a good bead lube. There are/is threads on TBN documenting the phenom. But the fronts that are unloaded should spin on the ground.

I remember a few threads that had people saying the 4x4 was broken since the tires were not spinning (turn out the rims were spinning).

This would be the first time that front AND back tires are doing it. Also the OP could lock the rear diff. (force more tire grip).

Going to pop some popcorn and see how this turns out!!!

If it is a hydrostatic transmission check for the optimum rpm for the engine while working. If the Rpms are too low the hydraulic pump will not be pumping enough fluid for it to operate correctly. Will it operate at low rpm? Yes. Will it operate correctly in a high demand situation? No.

that said, if at optimum engine rpm it should spin the tires. Wheel slippage or the engine lugging down and going dead should occur if the pump and transmission are good.

Unfortunately, it's probably working as intended. Got rid of my Mahindra Max 24 for this very reason. In my opinion, the HST relief valve on those machines is set too low. Bought the machine new and was beyond disappointed the first time I tried going up the hill to access the back part of my property only to have the paperweight quit pulling 2/3 of the way up the hill. Had several go arounds with the dealer and even got in touch with a product development guy at Mahindra that stated that is how it is designed. High range was completely useless on anything but flat ground. Got the dealer to bring another Max 24 to my property and mine actually performed better than it did. "Push more, pull more" my butt. There's no point in having the power if you can't put it to the ground. My L2501 w/ FEL & BH and ag tires will spin all 4 (or stall the engine if enough traction) in low range. I'm guessing my BX2670 would pull nearly as much in high range as the Max 24 did in low.

I'm guessing if the pile of Dirt or Gravel is rock hard and the tractor is not pushing in any more . Try moving the bucket up or down a little to brake up the pile . Or tilt the bucket back and forth a little. If the pile is hard best to raise the bucket over the pile and back drag a load of gravel down first .

Low . Barley pressing the pedal down

If you are barely pressing the pedal down you are not in low range. Shift the transmission into a lower range so you can push the pedal down more and yes you should then spin tires

 

[Garson]

Hydrostatic drive transmissions are sacrificing 20 to 30 % of your engine power. I used a friend's John Deere (about 30 HP) hydrostatic tractor (vintage about 10 years ago) to pull a cord of wood up my mountain. In low range it would rev up, move forward a bit and the engine would die down and forward motion would stop. I disconnected the trailer, went home and got my little 24 HP International 254 with manual shuttle shift transmission. It pulled the load over the mountain with little effort.

 

[Larry D Johnson]

I have the same machine and it will spin the tires in low range. Could be something as simple as hyd pressure too low.

Refresher needed:
Pressing pedal down less will more likely spin tires than pressing it more. Just like when trying to pull wood up a hill, less pedal is the hydraulic equivalent of being in a lower gear, very different than mashing it down like it’s a throttle pedal.
