A test drive will tell you much of what you need to know. Three speed trannys tend to get water in them if the owner washes a bit too aggressively. If it shifts good, then it is likely fine. People loved them.

At 160 on CL it should be in reasonably good shape. It should have a rear bagging assembly with it.

I use the non bagger model 10515's semi commercially and they are nice versatile lightweight 21" mowers and a pleasure to own.

The only buggar with them is the coils suck and like to die every few years so stock one up to have on hand.
