That was happening on my Craftsman lawn mower, similar model. I had a Sears maintenance plan on it, so I had a repairman come out. Wasn't the PTO switch -- it was that the little air intake hole on the top of the gas cap was clogged. The engine was getting sufficient air to run fine while not under load, but as soon as I'd try to engage the blades or the transmission, it would die. The repairman cleaned out the air hole, and the tractor ran fine. (Sure glad I didn't actually pay (extra) for that house call!)

Cub Cadet-Blades won't stay engaged


sounds like either a saftey switch problem or a bad drive clutch on the pto. usuallly the mower shuts down,not the blades, they may have changed this though. my best guess would be a safety sensor try calling your local cub dealer and talking to the repair person he can shed light on the problem.

Craftsman zero turn - blades won't engage


The PTO switch contacts to operate the clutch that starts the blades is defective. I have replaced mine and the new one just failed again. Sears must know this is a defect problem but so far they are quiet about the problem
