I mowed over a large rock that was hidden in long grass. It made a loud noise and the engine stalled but restarted with no problem. Now, when I engage the cutters the engine stalls immediately. All looks ok underneath and the blades can be rotated by hand. Any ideas please?
SOURCE: lots of smoke when I engaged stuck blades - now runs roughly
Most likely what you did was burn one or more spots on the belt. When the blades and belt stop turning, like in tall grass, the engine doesn't stop and will burn flat spots on the belt at the engine pulley. Every time the flat spot hits a pulley, it will jump and can set up a bad vibration. Run your hand around the sides of the belt or take it off and you will feel or see the thin spot(s) on it. Replace belt.
SOURCE: Mower blades engages but when I stop to empty grass they will not
yes it is there is one under the seat & under the dash & there is also one connected to the clutch/ brake peddle which is more than likely the one giving you problems is the clutch/brake peddle switch
SOURCE: engine stalls when blade is engaged
the best way to check is to run the engine with you on it then lift off the seat and see if the seat sensor is cutting off then put a bag with some weight in it and turn on the engine it should run ok if the sensor is working and lift the back box to see if the sensor works there.. the other cause could be a build up of grass in teh cutter area stopping the blades fron moving this can caus a stall if you get a hose and blast under the cutter guards and make shure the grass shute is clear for the grass to exit this may help to mine cuts out if there is a blockage here and the grass cant get out after it has been cut it builds up at the exit plates.. Hope this works AB
SOURCE: 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

Ouch! Is the clanking sound coming from the blade / deck or is it in the engine. It sounds like you hit a stump or a rock in that tall grass and stopped the blade. Under normal operation, what is suppose to happen is that the timing key will break off and you can replace it. If not, then usually the crank shaft will get bent and in such case, you probably need to replace the engine. It is also possible that on the lighter side, something got knocked out of kilter and the blade is hitting the deck on one side. Look underneath and turn the blade AFTER YOU REMOVE THE SPARK PLUG WIRE!!! NEVER EVER TURN THE BLADE WITH THE PLUG WIRE ATTACHED; THE ENGINE COULD START AND CUT OFF YOUR HAND!!! See if the blade is hitting anything in its full revolution. If it is, it'll make a hell of a racket. Good Luck.
