Rotary Cutter Bush Hog cutter issue. Help!

[sawtooth]

So I have a lightly used 6’ BH 286 cutter. Never had issues with it but today tried to slide the quick coupler onto the pto shaft of the tractor. I can get it started to where the first de-tents are on the shaft but then it won’t go any further. The pto is well greased and I don’t see any damage on the male or female ends. Anyone know what could be causing this? Just had it hooked up two days ago with no issue so not sure what happened?

I find sometimes rotating the pto shaft a bit can help ( by hand, with the pto shaft in neutral and the engine off). Lifting the brush hog so it’s level as pissible with the pto may help too; don’t have your feet under it though.

I did already try that but good idea. One thing I did find is that none of the 3 little bearings presses in. These are the ones located on the cutters quick coupled. Should any of them press in? It’s like I can’t get pass that point.

Yes, spray PB blaster or whatever you have handy. As you push in the collar it should unload the ball bearings and drop into the detents. Spray in there also.
Oh, forgot, first make sure the PTO collar can fully slide back all the way. So a good soaking may be in order.
Hope that helps a bit....

+1. I have a Rhino RC that got stubborn and little PB Blaster solved the issue. Years of grime and grit can get packed around those bearings.

AND, quit greasing it!!

Wipe that sticky crap off everything, and then spray "everything" with WD-40 (or similar) EVERY TIME you put anything on that pto! (pto/coupler/shaft where it slides ect.)

I've been doing that longer than most here are alive, never used dirt grabbing grease and have NEVER had a pto problem.

Yessir...good ol hard dry grease, lots of threads here now on how to take them apart...lol....

I pull the collar back all the way, and use a screwdriver to push the stuck ball bearings into the detents, then slowly slide the piece onto the pto shaft keeping the collar pulled back. It works for me.

I use a wax based motorcycle chain lube where I need a lube that will not attract dirt and dust.
You may have to use carb cleaner if its got grease and dirt packed in the joint.

Had no idea but makes total sense. This will sound funny but my grandfather always greased the pto and coupler so I have done the same. Seems totally stupid now that this issue has came up. Lol

Thanks guys.

Sawtooth,

Your grandfather probably used it 3 times as much keeping it from hardening up as well! :laughing:

I had a coupler that hadn't been used in decades. It hung up about the same place yours is hanging. I couldn't see any definite obstruction among the spline slots so I fook a file and worked on places where I thought there 'might' be obstructions. It finally went on and I still don't know which spot where I filed did the trick.

I had an old cutaway harrow when my grandfather was in the way out. Dementia must have been taking over when he took his oil can, filled with used motor oil, and proceed dribble it all over the part of the tongue I had to handle to hook up. There was no moving part on that section of the tongue. I can see him now, flexing the bottom of the can and grinning like a possum. Used motor oil is nasty stuff.
