I have a John Deere L130 lawn tractor and when I pull the PTO switch to engage the deck the mower tries to die and won't engage the deck. Could it be that the PTO switch is faulty and needs to be replaced or is it something else that's wrong ?

Could be the pto switch or the seat switch

Well, I have tried unpulgging the seat and when its plugged in the PTO switch does nothing and unplugged seat switch the mower tries to die.

Found the harness wire on the plug in was broken, hard to detect, but found that had to continue to repair, would like to have a solution

Have found the answer to my problem of blades not engaging on my Deere L130, The harness wires were broke although there was no indication they were broke. The other fix was the bracket, that holds the plug in area steady, was damaged.
