Electric PTO Woes
 

Today I started my 2084 and realized the snow blower was running. Looked at the switch and it was off. I turned it on and heard a click like it always does and turned it off and it sounded like it always does but the pto was still turning.

Couple of questions: Are the electric ptos all pretty much the same or are they diff for diff models.

Could my problem be from a bad switch or a malfunctioning seat safety switch.

You may need to check the air gap setting for your PTO. Sounds like it is too close and allowing the PTO to turn with the crank. :bigthink:

You either have one of two problems. It will be either electrical or mechanical. If there is a electrical issue as you describe, then simply "unplug" the PTO and see if it stops. If it does, then you will have to trace back where the problem is. If the PTO still rotates (mechanical), then it is time to pull the PTO off and apart and see what has froze up the movement of the magnetic clutch.

Or you have a bad bearing in the PTO. If it's a bearing they can be replaced as long as the rest of it is still good.

Many thanks guys this gives me at the least a plan of attack. I may be able to check the pto out this evening. Stand by I may have more questions.

EricR and I went out and pulled the wire out and I started the machine and the pto still turned. I shut it off and just turned the key to the run position and flipped the switch and got a click and when I turned it off I also got a click so electrically my clutch is working but it is definately stuck in the on position as it runs my 451 snow blower whether the switch is on or off. I have not worked on the electric clutches so this will be a first for me. It is a 1993 2084 and me without a service manual so please stand by for more stupid questions.

No such thing as a stupid question. We are here to help if we can. :beerchug:

Eric and I went out to the garage tonight and proceeded to remove the hood, grill, upper and lower metal around the muffler and finally the muffler itself. The plastic grill need some attention due to a couple of cracks. Will a quality 2 pt epoxy work on that. Finally we got down to the PTO. We got it off fairly easy and it got too late to go further as it needs cleaned up before attempting disassembly. I presume the three bolts with the springs under them when taken off will allow access to the interior. the pto shaft looks good as does the key groove and the key.

I think I have a PTO that will fit your tractor. It came of a Kohler M12 in my 1210, it's good. I had replaced the original one that failed a couple years ago so it only has about 100 hours on it. I'll post some pics of it. Take the 3 nuts off that hold it together and see if you have a bad bearing in the part with the pulley. As far as the cracks in the plastic if you can post a couple pics I'll try to give you some ideas on how to repair it.

First a couple pics of the PTO that I removed from my 1210. This style only has one bearing because it bolts to the front of the engine.

Second are a couple pics of the bad PTO that I removed from my 2182 to show you a some things to look for on your PTO. If all that is wrong is a bad bearing it can be pressed out of the pully and replaced. Much cheaper than buying a new PTO. This style has two bearings and mounts on the shaft but the coil is held by a pin that screws into the front of the block or by a rod on the Kubota engines that is bolted to the front of the engine. Hope this helps.
