Blades do not engage but can be turned manually. What are possible issues?
Jim, I believe your tractor has an electronic knob for engagement (if I'm right in you having a matching post about a husqvarna with a knob for engagement. And it also has a PTO clutch off the motor. Having a little slack in the belt is not bad if it's not so much that it doesn't grab at at all. Does anything happen at all when you pull the switch? If nothing happens at all, the switch could be bad, the PTO clutch could need adjustment or be bad, OR you may simply have a very weak battery that isn't supplying enough current to engage the PTO properly under loads. Sometimes the batteries and charging units in riding mowers are very borderline in being able to handle the loads and a weak battery can cause unsuspected problems.

Lever that adjusts height does not make blades turn. You need to engage the blade lever and if you can not tell if the blades are turning then they probably aren't. check belt it could need replacement.

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK

craftsman decks have a positive stop adjustment for the decks. A spring atached to the blade ingadgement arm pulls the tension pully into position if the cable is rusted inside the sleeve it wont put enough pull on the ingadgment pully and thus the blades dont spin full force the belts on the mowers have no adjustments only the pully . second thing is you may want to drop the deck and clean around that pully by scraping any rust off the surface under the pullys slide good luck

maybe the safty switch under seat might be starting to go out if that switch doesn't work the blades wont come on at all for safety

Sounds like you electric blade clutch is bad. I just had the same thing happen to my exmark mower. I was cutting grass and the engine just shut down. It would not crank over. Checked the fuses and replaced one blown fuse. The engine wanted to crank over but it was locked up. I looked the engine over and seen that the bearing in the electric clutch seized up causing the clutch to melt.
