Riding lawn mower repair help?

Might be reaching but maybe there's a Boglehead on here with some experience fixing riding lawn mowers. Was mowing this evening, hit a bump and the blades stopped spinning. Made no noise when switching the electric clutch on and off. Pulled it into the garage, looked underneath and saw the two wires going to the clutch were split and the blade drive belt was displaced upward off the drive pulley. I crimped the clutch wires back together, started it up and it worked, blades spun all seemed well. However, when I hit the PTO for the clutch to disengage the blades I quickly heard a "slapping" noise that was not normal so shut it down. Looked underneath and the clutch wires had broken at the crimping point. I noticed that when I manually spin the drive pulley for the blades, the entire silver housing moves, that allows it to hit the steering arms when the wheels are turned rather far. Not sure if this is supposed to happen or not but I think part of that housing is spinning inappropriately and ripped the wires? Any thoughts?

I would first check if it was still under warranty, if not call the manufacturers service line and they should be able to troubleshoot/walk you thru the repair. Out of curiosity what's the brand name?

I would recommend calling the dealer or a repair shop to determine what is the matter and to repair. There are some things a user can repair and others that require a professional. In my opinion, this is the latter. Good luck

Which housing is spinning? A cover over the PTO clutch?

Look at the housing and mounting bolts to inspect for damage.

Does the part you think is spinning inappropriately look like anything seen in the diagram here (as a fairly generic example):

Yes. To others, the brand is Husqvarna and out of warranty

Always surprised where people choose to ask questions. Lawnmower repair forum...

Good places for parts are www.repairclinic.com or www.jackssmallengines.com. Both sites have diagnosis aids and / or videos.

It's annoying to start a new forum and experiences on Bogleheads are varied. Hoping maybe someone here knew before I expose myself to the onslaught of newbie hazing at a new forum 🤣

Eureka! I solved it! The clutch is the silver and black section in the middle that's spinning inappropriately (bumps the steering arms so you know it's not supposed to spin). Looked at the parts schematic for the engine/clutch and there's nothing that seems to hold it in place. But there's that small silver vertical rod on the picture. Found that on the frame diagram and bingo, it's a "clutch anti-spin bar" rotate the clutch around to the hole you can see in the picture and it pops right in. No more clutch movement. Reconnect the wires with screw caps and a healthy dose of electrical tape and voila!

Something must have bumped that anti spin rod out and allowed the clutch to spin and tear the wires.
