This is a weird one.
From your description it is a faulty cutch relay, which would be fine but the wiring schmetic does not show a clutch relay.
However yours might have a clutch relay and I might be looking at the wrokg diagram as yo have not included the full description of your mower so I can not check to see if I am looking at the right diagram.
All of the wiring diagrams I have for Hustlers are basically the same.
Now if whne you get off the seat with the blades running, the blades turn off, then you have a blade relay and it is faulty
If when you get off the seat with blades running the engine shuts off then the kill relay is faulty
Have a look at where the realys are.
If there is only 2 then the PTO switch and/ or the kill relay could be the culprit
Start with the relays.
Std 30A headlamp relays available from any auto parts store for $ 5
That switch is $ 35 and is highly unlikley to be the problem as it is a plain sliding contact switch.
If you download the Hustler service manual ( it free ) and check the wiring diagram it shows the contacts.
Buy 1 relay and progressivly work across the bank of them.
You still have not provided the model numbers nor answered the question about how may relays are there ?
Most of the relays work on the ground circuit so if one shorts to ground it will remain active
I'm inclined to look at the wiring in the PTO curcuit as the problem, not the clutch. If the switch was working properly, when you push the button it should shut off power to the clutch, releasing it. Something is send power to the clutch after the switch is opened. I think you replaced the switch, which would then lead me to tear open the wiring harness and follow each wire through each component, looking for nicks, cuts bad connections, etc. I know that this is not easy and a VOM or a voltage reading test light will help. Long slow tedious task. To tell you the truth, this is a problem I like to work on, because it makes you use every skill in the tool box to solve. Customers hate it, because they think there is a magic tool in my box, which will allow me to diagnosis the problem in 5 minutes. You best tool is make NO assumptions. Test and verify everything twice, don't forget the safety switches, then move on.

Not to hijack this thread but my issue with the Raptor SD is I pull up the PTO switch to engage, mower works fine for 10-15 minutes then blades stop turning. Up and down on PTO switch, no go. Problem just started at 65 hours. Tested PTO switch with ohm meter and shows good. Might switch out the two relays. I hate these wiring gremlins Rivets but give you a lot of credit for trying to help here. Stanley
Switched out my relays to no avail....as you probably read. The good part is - they aren't expensive. Good luck. I am hoping to get around to narrowing down my issues this coming weekend.
SRS, you have a totally different problem and should have started a new thread. Please do so, because trying to help on this thread is going to confuse everyone. Sorry, I won't post any possible solutions here, as it will be a nightmare in no time.
I had that happen on he electric clutch on my sears tractor---the clutch it self may need adjusted-may be to tight-will keep running. if to loose it won't run--adjustment slots are on the bottom of the clutch--I think you have to use a feeler gage to set -when you tighten the spring screws.. You may have to ask your dealer how to set it.(I am starting a new thread as the last one is a tad off topic and 3+ years old)
Just this last week....depressed my deck clutch switch to kill the mower blades while operating and blades won't shut off.....they keep running. I shut off engine (with depressed switch) and when I restart, deck is then now disengaged and not active until I need to lift switch again for mowing. Also, with switch in off mode, and I get off the seat, the blades keep running too, which is a major concern with my 2 teenage kids mowing the lawn on alternate occasions.
Anyone else have this issue ?? Checked fuse and it looks fine...will replace anyway. Is there another fuse I am missing maybe?? This seems too easy for me to haul 40 miles in for service.
Thanks for your assistance in advance...cool site.
Sir: Have you ever adjusted an electric clutch?? I was lucky-my sears manual showed how to do it.Sub'd
