check all your pulley's including idler pulley's for smoothness and free turning,also check any spring tensioners for workmanship.try this first if this doesn't help let me know and we will go from there.

It could be a number of different things. The starter switch has 2 different positions for safety. One will kill the engine while backing. Have you tried engaging it with the switch in both positions? I would check that first. If it doesn't kill the engine while in the safety bypass mode for backing, it would probably be a bad or stuck limit switch on the reverse linkage.

You should have a two wire plug that comes up from underneath near the front where the machines engine crankshaft is. Normally the wires are one colored red the other black with the key in the run position engine (OFF) there should be battery voltage or close to it. Which can be measured with a voltmeter. With the PTO switch in the on position. If you have voltage you have a bad electric PTO if no voltage then you'll have to check voltage to and from the switch itself. Someone should be sitting in the seat to perform the test for on many machines the safety switches won't allow the PTO to be engaged unless someone is on the machine. A wiring diagram would help you trace the wiring to the switches and PTO much easier.

I need a little more information such as the engine manufacturer and the numbers off the tag on engine and what do you mean it purges do you mean the engine changes speed without you moving the throttle. This could be caused by restricted air cleaner or loose carburetor or either partially clogged carburetor

sounds like a broken belt.or it has come off the pulley

That depends on what locked it up? I need more info.

If there is a cut out switch under the seat it could be faulty and also if the foot brake has a cut off switch on it that may need adjusting. hope this helps
