Help John Deere lx188 Transmission Problem

I'm going to get an lx188 from one of my dad's friends that has a good running FD501v in it and a good deck, however, there is a problem with the transmission.

Transmission will not engage (at this point I'm pretty sure it's not the bypass lever, but I haven't seen it yet), I'm thinking it could possibly just be the level of fluid in the transaxle because I used to have a Husqvarna hydro tractor that would't engage either, and I added fluid to the tranny and it fixed everything.

Just wondering if anyone's experienced this before and what to do next, and if I should bother picking this up or not. Any help is greatly appreciated, thanks!

I can't say I have had this problem. But you have the right idea what to check first.

Re: John Deere lx188 Transmission Problem

Typically with that transaxle, once the pump cylinder bores start to stretch, they still run very well cold. Only once the oil heats up do they tend to start slipping, which is the clear indicator that a rebuild is necessary. It's almost impossible to keep running them to the point that they will not move at all, so I'd be inclined to believe that it probably is related to the bypass. Or the drive belt, or the drive belt pulley on top of the TA. Those have a notorious issue with the teeth wearing out, and you can actually hear and feel them vibrate but the tractor on't move. If the oil is that low to cause this, I'd be concerned of bigger issues.

So check the bypass and linkage. Then that upper pulley. That is a known issue as well.
