Working on a 42" Hustler model 927368/ SN 05011533

Helping a friend with his issue: When he turns blade clutch on the engine dies.......mower was operational until this problem developed. I would appreciate help with where to begin the problem search. Fuses are good.

Thanks in advance,

How did you test it? Some seat switches need a jumper to test.

If you’re positive the seat switch is good the next thing to test is the PTO switch.

Sorry Rivets this mower's seat uses a NO switch. So with the OP wife sitting on the seat it should a closed circuit; not an open circuit. Provides 12v to the kill relay to open the kill circuit whenever the PTO is on or one of the lap bars is not in neutral position.

Please refer to the Hustler FasTrak General Service Manual for wiring diagram and the IPL for the seat switch PN.

Note: Switch color is a hint. Its should be a black switch. If grey/gray it is the wrong switch.

I am not getting 12volts between the wiring harness connections from the seat nor the steering lever(s) switches. I see three relays on the mower...two in the instrument panel and in the starter motor area on the engine. The wiring diagram I have from Hustlers online parts manual only indicates two relays...

Am I looking at the correct diagram (s/n 05011533)?

The owner says he lost the key so he started the motor by turning the key switch with a knife. I have replaced the key switch with a new one...no joy. Battery is new, 12volts strong.
