Hi, I picked up an old '83 Toro, model 58170, rear tine 8hp tiller; however the tine drive belt is loose when engaged. Anybody have a service or owners manual that has adjustment instructions?

This tiller is similar to the Gilson 51135 except mine has a total of four (4) belts instead of the three on the Gilson.

Any help would be appreciated.

thanks, Joel
