See link above, the tractor has a single belt for both transmission drives. Is the belt tight? Has it ever been replaced?
Is the belt tight? It should be tight enough that it will not slip on the pulley. # 37 spring on the idler is the tensioner.
Is forward ok? Just won't steer right/left, and reverse?
OK, Let me opt out and see if anyone else has seen this. Please do not respond to me or it will lock the question. Sorry.
