My mower wont go. Riding Mower w/ Bad Transmission?

My mower has had some forward motion issues for as long as I've owned it. This is just my second season with it.

Last year the mower would stop moving after running for a while. A few wiggles in the seat and it would start moving again.

This year has been a little worse. I've had a harder time getting it to go at all. This past weekend I was riding for less than 5 minutes and the forward motion just stopped. No pushing or wiggling could get me going forward or backwards. I let it cool down and still no go.

The belts are in good shape. I'm guessing that the transmission has gone bad somehow. If that's the case, is it worth fixing on this old machine? Thanks!

If you put it in the highest gear will it pull? This is what mine was doing and kept getting worse. Finally got where for it to pull itself it would be going too fast to mow efficiently. Purchased a belt from local co-op (the one they said went on it) and didnt help a bit. Left the mower sitting all that year and decided to try it again this year, but I ordered both the belts online using the part numbers from MDT. As I was puting them on I noticed my new belts were much wider than the one I bought locally. One of the belts I had put on by the co-op a year before I started having the puttling problem. Both belts combined being too narrow made it where the one pulley wouldnt spread apart correctly so it would get grip to make it pull.
When I had given up on the mower the first time I was told it was the transmission, but furtunately it was not the case.

The first thing I would check is the wheel drive keys. If you find the transmission is bad I would say the next step would be the local mower salvage yard for a used trans.

I have the same problem with my 10 year old Murray with a hydrostatic transmission. It simply stopped pulling. I've attempted to check fluid level, but can't find a stick or drain plug. I'm not a mechanic and don't know if I should junk it and move on or try to repair it. It's been a real work horse and I'd like to keep it going if I can. Can anyone give me any suggestions as to how to determine what I should do?

That's exactly what it was doing? For a while it was working at higher speeds. Now it has no pull at all. I'll check the belts closer and look into replacing them. Thanks.

Sounds like you put to much oil in the transmission and the oil has messed up your fan belt. There are two shafts sticking out the side of the trans. The oil level should be about a 1/4in from the bottom of the shafts. You should be able to see oil dripping out the shafts. If you do not then you have log grease in the transmission. This grease has dried up clean out the trans and put 90weight oil in it. This is a strat of trouble shooting. Some of. The companies put grease in these trans and this would run dry in a few years. Good luck

Yea there is a fan belt under the plate that the transmission sits on. You need to have a way to transfer the engine power to the trans. Most of these models do it this manner

So can you give me the part number for the fan belt?

No fan belt # I would think it could be called a drive belt or pump belt take your pick. It has a fan and the belt drives the fan so lets call it a fan belt. Who in the world cares what you want to call it. No I don't have a belt part number and not going to get one. The money for the repair job is in the bank and the customer will be cutting grass as soon as it quits raining I think??

:smile: I doubt that it is the tranny. That is a variable drive system. I have found that working on MTD LT's, that aftermarket belts just do not get it. MTD belt #'s for the that drive: 954-04001A and 954-0241A. I would pull the battery and the battery box, and check the drive pulley on the tranny. It has a serrated center hub, and I have found the teeth seared off. Also check the variable speed pulley, I have found them froze up. The tranny is a single speed unit, with forward, neutral and reverse and very seldom gives you any trouble.

That is what my picture was of but on a John Deere seeing that what I was working on at the time. Now as far as Carscw wanting part numbers I took it as he was pulling my chain calling it a fan belt so I was just giving it back. Just having a little fun.
