Last year I purchased the wallenstein bxm32 and running it with a 1025r. I'm concerned about the PTO brake on the tractor as the PTO continues to spin for a few seconds after disengaging the tractor at low RPMs. The wood chipper rotor weight is 70lbs, seems like a lot of inertia for the PTO brake.

Should I be adding a overrun pto clutch, similar to the one below. I've asked the dealer and they thought I'd be okay without; of course they're not paying the repair bill.

Pretty sure most farm equipment that have large inertia loads (haybine, hay baler and etc ), have a built in overrun clutch.
What are other members doing - am I just over thinking it? The cost of this overrun clutch is $100 cdn; I assume the PTO clutch would be much more. :)

I see no downside to them other than having to cut the PTO shaft that much shorter.

I have one similar I use on my 2025R with the rotary cutter and hay tedder, both keep quite a bit of inertia after the PTO is shut off. I don’t know if it helps but it definitely doesn’t hurt. The only watch out is that the attachment keeps running even after the PTO is shut off so be extra careful around moving shafts and cutters.

I have the same one........fantastic for the chipper ,Blower and brush mower.

The ability to remove it with one hand is great.

With the quick hith all my drivelines have penciled out perfect . They were cut in some cases by the previous owner.

Most tillers I've bought had driveshafts that were borderline too short so this ORC fixes that issue in a snap.

I've found no downside yet and have no desire to deal with replacing my pto brake.

I use the same one as well, added a quick hitch at the same time, which eliminated the drive shaft length issue.

I'm surprised those chippers and blowers don't have free wheel. My Maschio flail mower has free wheel built in. That thing spins a good minute after the PTO is shut off.

I had been wondering the same thing I couldn’t really find anything too easily and hadn’t gotten around to more research. I just got a chipper and didn’t even know about or think about the wear on the PTO brake. I’ll check out the one in your link; thanks!

I was thinking the same thing, my flail spins for a good bit after I disengage.

Cutting the shaft is easy. Takes 5 minutes. Getting those guards off and on however is a 2 hour job.

If it has free wheel, the drum spins for a minute but the PTO stops immediately.

Stupid question; but before I order that one in the link; safe to assume PTO shafts are a standardized size and that fits/works on my 4066R?

Should be all the same. 6 spline x 1 & 3/8th"....iirc

Old 2N & 9N were a touch smaller.

There are Fine spline pto"s but they are 1000 rpm iirc........They do that so you don't get confused is the theory I'm guessing

Thanks! I’ll order it then. You had mentioned on my thread about my new WC88 about getting an ORC and I was trying to figure out what to get!

Remove the guards permanently and that problem is solved. Although there is a new issue created of course, and the safety police will be along shortly to issue citations for it.

Three years ago my nephew was brush hogging our two track with the 420u when it started to rain very hard. He tried to quickly get into a higher gear and because the brush hog was spinning when he dumped the clutch it broke gears in the transmission. $2k later we all learned a valuable lesson. It is one of the most valuable attachments you can buy.
