If I was an electronic nerd

I would install a device on my flail mower shaft to let me know when I picked up something, that stopped the mower drum. Like a couple days ago. I got a piece of chain link fence wound around the drum and stopped it. By the time I figured what happened, I burned up the slip clutch disks. At least the slip clutch works.

I bet that would happen so fast either way, electronics could not stop it.

The 7700 John Deere combines have a low shaft speed sensor on them so you can see when something is about to plug up or has plugged

I know the feeling, once I looked back to see the smoke rolling off of mine! When I was young we had an IH trailing sickle mower that had a noisy slip clutch, no fiber discs. It made a brrrrrp noise!

The real fun is when you snag about a 50 foot piece of Gaucho barbwire with a flail mower that does not have a slip clutch. A torch would have been handy, but I did not have one, and wore out a set of big side cutter pliers, but got it out. was mowing some weeds along a neighbor's fence and grabbed a tail end of Gaucho that jerked reel about 1/3 full into the mower. Rather than laying down in the ticks, chiggers, ants, etc. I drove back to the shop with the reel hanging under the flail. I now carry a pair of these on the tractor the flail is used on.

I carry a big cutter in my truck. I found what ever winds up will unwind, by pulling it out. I did that with a long piece of chain link a couple years ago. Stan

My combine has a couple clutches like that two sets of jaws held together by spring pressure. An awful racket when they slip.

I dunno about, technology exists to instantly stop a 4000 RPM saw blade 'fore it chops your finger off, seems like this would be simple compared to that?

That would be easy enough to design/build. But if I understand your dilemma correctly, I?m trying to understand why you would need one because of several reasons; First, I would think the tractor would pull down, second, the change in noise, third, the output of the mower should change, and fourth, the feel of the tractor should change.

If nothing wakes you up, such clutch WILL. LOL

How long did it take to burn up the slip clutch? Or was this the result of multiple stoppages?

I usually notice within a few seconds when my flail mower stops. No slip clutch, but the drive belt serves as one.

It wouldn't be that difficult to put together a PTO shaft speed monitor, but it would be one more thing to deal with. Maybe you could mount a mirror somewhere so you can check the mower shaft without turning your head. (I'm guessing that like most of us old pharts, you find it tough to keep twisting around to check your implement.)

I think what happened is the first time the clutch loosened up some when it spun from the wire. When I removed the wire I should have readjusted the clutch again. I started mowing again, and it weas slipping a little all the time, until it was gone. I like to see the speed when I am in tall weeds to slow up some to get a good cut. Stan
