Bush Hog Removal

Hello. I am completely new to this board and have a really basic question. I purchase a JD 1050 tractor with a Bush Hog 6' mower (attached to the tractor's PTO when purchased). I just bought a scraper blade and need to remove the Bush Hog from the PTO.

The PTO connection on the Bush Hog has a little spring loaded pin that I can push in. However, I cannot seem to pull the Bush Hog off the PTO while I am pushing the pin in. Any suggestions? Has anyone here encountered this type of problem before? Like I said, it's the first tractor I've owned, so mayble I'm not going about this the right way...

Many thanks,

Just pull tractor forward shaft is 2 piece it will make it easier to beat off. they can be a real pain and then you can get a better grip where you can push button with 1 finger and grab pto shaft with both hands and pull like theres no tomarow.

Well, you're doing the right thing. Assuming you're pushing the pin in far enough, the problem likely is that it is stuck on the shaft.

How long has the brush hog been connected?

Start by squirting some penetrating oil around the shaft so it lubes between the PTO shaft and the coupler. Then I'd likely try tapping it while pulling on it.

Good luck.

Thanks for your advice. The Bush Hog has been on there for probably two years. I drenched the whole connection with WD40, thinking that it was just stuck. What I don't understand is how the spring loaded pin connects to the PTO splined-shaft. It can't go through the shaft, can it? If so, what good does pushing it in do?

The PTO shaft has a groove around it that the pin rests in. When you push the pin in there is a cut out portion of the pin that allows removal from the PTO.

Thanks! That was the missing piece of the puzzle for me. As I said, this is my first tractor, so everything is trial and error. Incidently, when the pin is pushed in, where is the best place to grip the Bush Hog to pull it off the shaft? If I have one hand pushing the pin in, that means I only have one hand to pull that heavy piece of machinery off the shaft, right?

That's why you use the hammer! If a pto machine has been hooked up for a great length of time, gone through ups and down, peaks and valleys, flat ground and ditches- there is a tendency for the connecting points to mushroom a bit- that would be the pin vs the pto shaft groove. Might need a bit of 'persuasion' with the bfh to pop it loose after the lube has time to work. One hand pushes the pin and pulls to the rear, the other one taps with the hammer. Then you beat on it and curse.

You are not trying to pull on the machine- you are just pulling on the shaft, which telescopes into itself so it can be removed from the PTO. Put another way, when everything's working right, you should be able to unhook the PTO shaft before you remove the two lower arms and the top link (which together, make up the "3 point" hitch).

Another problem you may be having is that the grease in the telescoping shaft may have dried out and set up, so the shaft won't telesope like it should.

I've already unhooked the "3 pts.". I guess it's possible that the weight of the mower is putting pressure on the shaft as I try and get it off...
