Default PTO Fun
The PTO on my 1541 with a Command ECH23 started failing 5 or 10 minutes in cutting the grass. I do the usual trouble shooting and find that the field in PTO is an open circuit. My old one was just under 3 ohms. So I proceed to take the PTO off. (Does anyone know a fast way to get the inside nut on the exhaust off on the oil filter side. It is a pain to go one twelve of turn at a time).
I pull it apart and the clutch and find the wire in field are being eaten by the rotor. The field coil is sticking out over an eight of an inch from the cup it is set in. In the old one I have laying around the field coil is not sticking out like this. The bearing is also shot. Hard to believe, this was purchased from Cub Cadet just five years ago. My old one lasted over a decade.

Here is the problem. Two of the bolts on my the old field I have laying around are bent pretty good. Can anyone think of a way to straighten them without making them too weak?

Maybe it is time for a new Extreme PTO.

It's not a nut, it is a stud (unless I'm not understanding what bolt your talking about). Remove the muffler, then remove the bolt.

Sure can. Throw them in the trash and buy new.

Sounds like it.

Took the advice and got an Extreme clutch. Count me among the converted. Easy to install. The only issue I had was wiring a diode into the circuit. Kohler specifies it for their EFI engines.

Old stuff is where it belongs, in the garbage.

You know the drill, we need pics.

I don't understand the need for a diode, please explain.

Sorry there are no pictures. It was a rush job, so I did not get the camera out.

I did have to go a long way up the line to get to wires where the insulation was not broken. Time to rewire this thing. I will document the rewire job when I do it.

Things like the PTO or a relay usually have a diode across the power feed. The coil will send a spike of power back down the positive line when the power is cut and the magnetic field collapses. Not a big deal if there are no sensitive electrical components involved. The EFI engine does have delicate electronics hence the need for the diode. The diode allows the power to cycle through the coil. In hind site, it is probably not needed since there is a relay in circuit, hence no way for the spike to go anywhere. Still not a bad idea. I probably should put a diode on the relay power.

WHAT......?????


The Electric PTO's on my 1450 and 784 have been on since they rolled off the assembly line (30-40 yrs) with no diode.

Maybe I did not explain the need for a diode very well. The diode is not there to protect the PTO (or other coil), it is there to protect other things that are connected to the same positive supply. This is only needed if there are delicate things like integrated circuits being used. Nothing like this on Cubs up and through the Cyclops tractors. Not sure about tractors after that. Do a search on diodes and coils for good explanation.

The OP has a replacement EFI Kohler engine in the tractor. He said Kohler recommends the diode to protect the EFI system for the reasons he stated. I agree, with the relay, it isn't likely needed, but not a bad idea.

No, the old machines don't need or use them. Neither did his originally.

In this particular situation I agree with the OP as far as the diode. Why take the risk of smoking the computer for the EFI. For the older stuff no problem just install the new PTO and be Happy.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
