I have a 48” turf tracer (model tts481ka483). The belt that runs the hydro pumps broke. Does anyone have some kind of diagram or explanation for putting a new belt on? I called exmark to see if they had something they could email me but they didn’t. I tried to just figure it out but got stuck and about went crazy. Also, the little chain that attaches to the hydro idler pulley arm broke off a long time ago. I got the feeling that is an important part for replacing this belt.
