Hi guys. A family member has a Cub Cadet 33" walk-behind self-propelled mower. I replaced the mower deck belt recently. Since then, the belt has become very loose, with a lot of slack in the tension of the belt. Any suggestions as to what I might look for? Thanks!
 
Did you compare the belts before installing? The belt could be longer. When you installed it, did it seem to be the same tension? Where did you get the belt? Generic auto parts belts are not the same as mower belts.
 
Idler/tensioner pulley spring jump off?

Belt routed proper?

Definitely size the belts up. No two are the same even from the same brand.

Agree with Mark, did you shop at an auto parts store for a MOWER belt?
