Turn off mower blades the electric clutch spins and the two green
Turn off the mower blades the electric clutch spins and the two green wires wraps around the electric clutch pulley? It started when the belt shredded into pieces as i was cutting tall grass and it snapped off both green wires from the electric clucth. SO I got a new belt from sears and same gauge wires from auto store. I turn on the mower blades and it spins normal (everything perfect until) but when I turn off the blades the elctric clutch spins and sucks up the long green wires??? i tried everything whats wrong when you turn off the mower blades and the clutch spins also sucking up the wires??? i tried also turning off the lawn tractor with key while mower blades is engaged and it stiill sucks up the two wires as it wraps around the elctric clutch pulley???
I thought I was ready to mow until this crazy problem!

Re: turn off mower blades the electric clutch spins and...
There should be a metal "anchor" that bolts to the chassis or engine. It has a rod that sticks downward, fitting into a notch in the clutch to keep it from turning. It must be missing or broken, or maybe the clutch is the wrong model, and that's why the clutch itself spins and rips out the wires.
Good luck! Please rate if you found this helpful, thanks!
Re: turn off mower blades the electric clutch spins and...
I have a dys 4500 24 HP 42 inch model 917287251 when I ingage the blades they make a loud clanking sound. Also the right blade (when you are setting on mower) continues to freely spin when you stop the blades. That blade and the pulley above on deck seems very loose.

To engage the blades is it a knob to an electric switch that you pull?
If so does the wire from the switch activate a electric clutch?
Is the wire damaged and shorted to the frame, is the clutch shorted. If you provide the brand name and model number I might be able to find a schematic for your mower.
Sounds like either the switch for the blades is not shutting off the power to the electric clutch or the clutch itself is not disengaging. I would shut the mower off and unplug the wire to the electric clutch and then start the mower and make sure the blades do not turn you may have the belt for the blades on the wrong pulley and it might be causing the blades to turn. Hope this helps.
Check that the blades turn freely. With the engine off check that no blades are spinning visually then try to turn each one by hand. Visually check that none have wire, trash, rope etc wrapped around them. Also check that any pully's on the deck are not frozen rusted in place. Also check that no pully's are broken off from their mounts and sitting at crazy angles.

first unplug the switch and see if it still operate then disconnect the spark plugs then turn the blades threw the discharge opening and see if the engine rotates when moving the blades this will tell you if the clutch is stuck then connect the spark plug wires back on and next to the engine base you will find a 2 wire connector that feeds the clutch power and ground unplug that connector and start the mower see if the blades turn this will tell you if you have a mechanical failure if it does not operate with the wires unplugged its a electrical
If it were me I would check the PTO switch with it running and use a dvm or test light to see if switch is working or defective , you could just have a bad wire connector at the switch or at PTO clutch ....look for discoloration or spread terminals, good luck
The tab sticking down fits into one of the groves on the cluthc to keep the clutch from spinning while the engine is running, as well as when you engage it. The wires are broken due to the clutch bolt backing out, or the belt or part of the belt could have broken or lost some of the chords that have spun and wrapped around the wires and just broke them off. You need to verify that the bolt is tight first. The tab should not be bent, if it is you need to straigten it before you reinstall the clutch. Next reattatch the wires. Dont put the belt on yet. After you have reconnected the wires, test for 12 volts. You can do ths two different ways, the first is sit on the seat with the engine OFF. Turn the key to the RUN position, then engage the PTO (turn the blades on), you should hear a CLUNK. Do this two or three times. Or you can sit on the seat ( or have someone sit there) and use you volt meter set to DC volts and check your connector for 12 volts and ground. Then put the belt back on and try it out.
If it's like mine (MM 875), it has a plastic "clutch" that has little edges on it that broke off when I was chopping sticks with the mower ;-) Went to the local B&D place and got a new one for less than $3.
But now I'm worrying about the nut holding the blade on -- if I try to get it good and tight, the plastic "clutch" spins around off-kilter... Funny how I never even looked at the blade after I bought the mower used, but never worried about the blade being loose and flying off.
