I have a yard-man 50" cut tractor. The model number and serial number have both been removed so I can't quite figure out what year it is. I'm thinking it's a 1994. I bought what I thought was the correct deck belt but now can not figure out how to put it on. The tractor has a hydrostatic transmission and a 22hp kohler engine. The belt seems way too long however it is the same size as the one that came off.
