My neighbor has a Hustler model 935916 serial number 16124755 zero turn mower with 200 hours on it. He said he replaced the PTO clutch last week. Today I heard it stop when he was cutting grass. He asked me to take a look. It wouldn't start. I found the 15 amp fuse blown under seat and replaced it so he could get to my basement. Don't ask me why I get into things like this but anyway they are good people so I am trying to help.
I removed the plug in from electric clutch and it showed 2.8 ohms which I think is in specs .
He has bypassed the seat switch . With key on, engine off and I pull PTO it pops that 15 amp fuse . I had plugged the wire back in electric clutch when checking. If I remove the fuse and put a wire across where fuse goes just for a second its like a dead short. Much better than blowing fuses. I can tell pretty quick doing that.
All looked good at PTO switch but I didn't test it yet . The clutch does Ohm correct. Wire shorted maybe ?
He did mention to me that it has been breaking the bolt that holds the clutch on. He said he got a grade 8 bolt to cure that but I would think this mower came with grade 8 .
Before I start on this tomorrow anyone got any tips on what might be happening to cause it to blow that 15 amp fuse. I did notice when we first replaced the fuse this morning to get it back running it sounded like the starter was dragging but it did finally crank and run. He engaged the PTO and it blew that fuse and wouldn't start back until he put another fuse in.
I would think it the clutch was bad it would have high resistance when testing with meter but its normal or within the correct range at 2.8 ohms. Thanks for any info.
