Craftsman ZTS 7500 dies when engage blades or when engage transmission

Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.

The seat occupied switch energizes the operator presence relay. This relay allows power to the PTO clutch from the PTO switch only when energized (operator in seat).

A simple test

1.PTO switch OFF
2.Ignition switch to ON position.
3.Engine not runnjng
4.Operator in seat

Pull PTO switch. You should hear the the clutch engage with a notable pop. Then turn off PTO and it will make another pop or clunk when it disengages.

Similarly with PTO engaged, if you rise from the seat it should disengage.


Also a failed charging system may allow the engine to start and run but not provide enough current to properly engage the electric PTO clutch. With engine running check battery voltage is greater than 13VDC.

Sounds like a problem with the governor. Start it up. Don't engage the blades. Drive to a hill. Idle all the way down. Try driving up the hill. The motor should pick up when it slows while pulling up the hill. If it doesn't, the governor isn't working right.

The first thing to check is the fuse,it should be located underneath the battery.

There is somthing in the PTO that is binding up. I am assuming the PTO is for the mower blades. The belt(s) could be binding up, not on the pulleys, etc. The blades should turn by hand easily.

check your blades to make sure that they are not hitting the deck,, this would cause the knocking sound

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

Cody,
Yes, I am sitting when I do engage the blades on my craftsman zts 7500. All you do is pull/push the engaged button to your left well you are seated.
