Craftsman Riding mower problems with pto engaging and handle bars killing motor...

I am helping my grandfather fix his craftsman zero turn mower model # 107.277740.. I think I am having multiple issues.. First he had to jump start it.. he says it is a brand new battery, but it could need charging.. we get it cranked and engage the blades and I am off and mowing.. It mows 10 feet and the blades disengage automatically, furthermore the switch will not re-engage the blades.. at this point I kill the motor and check wiring for shorts or any obvious problems.. none to be found. The only thing I noticed was that while the ignition was turned on and the motor not running the switch did in fact cause a popping sound from the rear of the tractor as if it was trying to engage while not running. I jumped it again and got it started.. blades engaged.. I mowed about 10-15 feet and same thing happened.. blades just stopped working while motor running and switch pulled out. this time I tried moving wire while engine was running.. It did no good.. I did notice something really weird.. if you lay the right handle down while the left is up it kills the motor but if you lay both down or leave the right up and lay the left down it does not kill the motor.. Finally I jumped one last time and this time mowed about 130 feet and it ran great then all of a sudden started to disengage and re-engage the blades rapidly maybe 4 or 5 times .. so I parked it and have no clue where to start trouble shooting.. I am at my wits end.. please help...

It sounds like you are having a hard time getting the lawn mowed with the Craftsman lawn mower that just won't stay running. I found some links that may be of some help with the problems you are having with your tractor.
