I have a K2 that I ran this year and it got me through the season. I'm a young farmer just starting out so bear with me. When I was finishing up this past year the nut backed of the drive shaft/input shaft into the transmission and threw the drive belt. After getting the belt back on sheave when I let out on the clutch the shaft slows way down almost to a stop and the combine will not pull itself. Does this mean the clutch is busted? The tension idler on the drive belt is all the way out so I assume I am going to need a new belt as the old one appears to be stretched.
