Toro Wheel Horse 12-38 XL, mid-90's I think. Plastic engine cover and all (apparently Wheel Horses from the 80's were all metal and something pretty decent?). Anyhow. It was given to me years ago and I have been using it more recently, but, it's developed a problem where it will just stop moving. As in, I'll be driving forward and it will just stop. Won't go into reverse or go forward, something sound like it might be dragging/disengaged, but no clunks or bad noises. Fiddle around, bang on things, and eventually it will decide to move (usually after a good length of time). At first I thought it was pulley that applies tension to the belt that goes from motor to transaxle. I have not been able to verify that though, and it seems kinda weird that it'd just suddenly pop out and get stuck while in actual use--first time it happened I was changing direction and thought it had to be that, but now it's doing it at random times and while moving. Maybe it is this and just needs some lube or something? It seems free to move and apply tension. It does seem to only do it when I am moving my utility trailer. It is empty and I don't think overloaded in any way, but more load than usual. One other thing. The pulley on top of the transaxle has like a quarter turn of play in 1st gear. Is that normal? Seems like a lot of gear lash.
