I have an old rear engine Snapper that was part of a clean-up project, not sure how long it had been unused. I gassed it up, changed the oil and plug, filled the battery and charged it, replaced a starter gear, and pretty well took off mowing. It pulled quite well, and mowed like a champ. Didn't cut straight, but I used it for "bush hoggin" in places that hadn't been mowed for years. I even took it over in the back pasture and mowed along a little drive path, and the only place it needed help was crossing a drainage ditch that runs across our place. The banks are a bit steep, and I had to help it up each side.
It was starting to not pull as well in forward, but still strong in reverse. I'd have to nudge it a bit to get it moving in forward, but it would keep on pulling and mowing once it got moving. I've hesitated trying to break the bolts holding the frame extension, that's how the cables are adjusted I believe, although I'm not sure that's what it needs. I have the service and parts manual, I believe that's what got me signed up here was in looking for those, and I may still owe the uploader a great deal of gratitude, when I can relocate that post.
Anyway, I once checked the driven disc measurement and it was near exact. The old belt broke and I ordered one online. When I get that, or while I'm waiting, before putting it back to mowing, I'm hoping to find suggestions on how to either get the drive discs or cables adjusted, or possibly find if it needs to be replaced. The disk still appears to have plenty of rubber on it, but I don't recall finding a measurement for that(simply a photo drawing of one looking rather worn)
Any suggestions for getting this mowing again would be much appreciated
