I have a craftsman 91725251 lawn tractor, w/42"QC System mower deck. The mower deck wont disengage whether tractor is running or not. Can you tell me what the problem is and how to fix? I'd appreciate your help. Thanks

Lower the mowing deck to the lowest position. Don't start the tractor engine but put the gearshift in neutral and set the parking brake.

Look at the idler pulley while someone engages and disengages the deck. When the deck is engaged the linkage should move the idler pulley to tighten the deck belt. When the deck is disengaged the return spring should pull the idler pulley away from the belt so the blades will stop turning.

Look for item 72 in the parts diagram, this is the spring that disengages the pulley from the belt.
