Hydrostatic mower goes in reverse but not forward. Only 73 hrs on it!
Mower just came to a stop. Engine still running but will not go forward. Goes in reverse fine but when I put it into forward it will not move. I checked belts and made sure the free wheeling lever was in the right position. Please help
Re: Hydrostatic mower goes in reverse but not forward....
On my hydrostatic there is an adjustment on the forward/back lever which can be made to run all reverse or all forward. Normal setting gives both of course. Look at that adjustment. Maybe something let go.

If this is a hydrostatic transmission, one of 3 things:
1. Drive belt off pulleys (recommend replace belt if so)
2. Belt broken (obviously, replace)
3. Hydrostatic transmission failed (least likely, but this is an expensive repair shop issue if so)
This happened to my GT1554 two weeks ago - fortunately, replacing the belt resolve the problem.
Hi, remove the battery and battery support tray and clean all debris from around the hydrostatic drive, fan and cooling fins. Your problem is caused by the hydrostatic drive overheating. Hope this helps, regards Phil
Use hydrostatic fluid. Consult your owner's manual for information. Do not use hydraulic transmission fluid. If you do not have your owner's manual, you can find one on www.managemylife.com Just go to that site, click on manuals and enter your make and model number.
Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,
if the engine is running, but the mower is not moving generally you have a problem such as:
1) the main drive belt between the engine and transmission has failed
2) the main drive belt is good, but the hydrostatic transmission has failed.
first issue can be resolved by about anyone with a good selection of tools, a twelve pack, and a couple warm sunny hours. second issue means you are going to get a new mower unless you have an expensive mower and it is worth spending 1500 dollars to get a new transmission for it.
Assuming the engine is running and sounds good, you need to check the drive belt. With the engine OFF, make sure the topmost belt which goes from the engine to the top of the transmission is in place and snug. If it is there and in good shape, then I would suspect the hydrostatic transmission has failed. If the belt is not there, replace it; if it is loose, replace it. AGAIN DO NOT ATTEMPT TO PUT YOUR HANDS UP INSIDE A RUNNING MOWER.
Does it have gears or a hydrostatic (automatic) transmission?
If it's a gear model, sounds like a loose drive belt.
If it's hydrostatic, it could be a belt problem or a problem inside the transmission. If it's a tranmission problem, this is not good. Many of the transmissions on riding lawn mowers are not serviceable - they are just replaced.
In the back of the mower...probably under the seat, there should be a lever to release the transmission, or it is on the back plate. As far as the noise when trying to move drive the mower, the brake in the back, next to the transmission is jammed, use a 1/2 inch wrench to loosen it maybe 1/4 turn and this should unlock the brakes
Check for a worn belt first.Then check the linkage. Next jack the unit up and try to run it forward and reverse with the engine running.If there is any movement at all in either direction then check the fluid level to see if it is up to the top.The worst case is the hydro. unit has a stuck check valve or something broken inside.Hope some of this helps. donnyb60
