Problem with brush hog - need advice.

[Crown & Roots Farm]

Hey all - Looking for some advice regarding a brush hog.

We recently bought a 1962 Ford 2000 that came with a brush hog that is giving me some problems. The brush hog spins fine but when I lower it to start cutting it will cut for a second then loses power and the spinning slows way down. PTO continues to work, just the blades stop. It has the proper amount of fresh oil in it. We are thinking its got something to do with this old slip clutch.

Anyone know anything about this one? Should i just try to find a replacement part?

could be that, as you put force on the shaft changing length it slips? i would replace the slip clutch and check and grease the u joints.

I speculate a bit of tightening will put you back in business.

Thanks for the reply, will see if i can tighten it next couple of days. it doesnt seem to be budging at all at the moment, could be rusted together pretty good

The blades stop completely but the PTO is spinning? That slip clutch doesn't look like it's slipping to me from that one picture, did it make a noise or smell?

What happens if you spin the blade manually (engine off, PTO off)? Does it spin the PTO shaft? Slop? Have someone else hold the shaft and spin it again.

Is it just me or does it look like the PTO shaft has been spinning on the clutch shaft? It likes bright and has circular marks.

If rusted together solid, it is unlikely to slip.

Pay attention to what parts of the PTO shaft clutch assembly are still spinning when the blade stop. I agree with K5L that it looks like PTO is spinning on input shaft to slip clutch and like others say that clutch looks rusted solid.

what holds the PTO shaft onto the input shaft of the clutch? Is there key sheared off?

thanks for the reply, i just spun the blades by hand and it does spin the pto shaft. also spun it while someone was holding the shaft and it moved with the blades spinning

I think you are exactly right
