Scotts riding mower transmission won't engage.
I have an older Scotts riding mower model 42531x7a or x8a, I'm not sure which, and I took it out of the shed for the first day of the season and to my surprise the drive transmission won't seem to engage, not for any of the forward or reverse speeds. I've checked all the connections I know of and they all seem fine and in fact it was working well when I put it away months ago, though the transmission did slip a little. The belt is intact and turning, the speed shifter is a little loose but still connected and moving the joined parts. The clutch moves and tensions the belt still but still it seems as if it's not engaging. Any help or redirection would be greatly appreciated.
