PTO Shaft

[goatman]

I have a KK 5ft bush hog and hooked up for the first time yesterday. And when I tried to attach to the tractor the shaft about 4 " too short?? I thougt the thing woud pull apart to fit but as hard as I could pull would not seporate?? The entire shaft is encased in hard plastic cover so I can't tell if it comes apart or not??? Also the attachment at the hog has a resptable sized bolt holding it on?? I thought it was suppose to be a shear pin or removeable clip?/ As you can tell I don't have much experience with bush hog but was planning on getting some this week weather permitting.. I plan on removing the shaft to night and return to where I bought the hogand have them look at it , it was getting dark when I did this.. Thanks for any advice /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

You need to pull on it real hard. It's probably been setting for a while and the two pieces have somewhat rusted together. When you do get it to slide apart, slide it all the way apart and give it a good coat of grease.

Also, the bolt IS the shear pin. That's what they call it because of its use.

The shaft should definitely slide apart. As BillyP stated, it is most likely just stuck. If you can't pull it apart by hand, it may need a little "friendly persuasion" /forums/images/graemlins/shocked.gif. A few taps with a hammer may do the trick. Or, back up close enough to it to hook up JUST the PTO shaft to the tractor, making sure it locks onto the tractor PTO. SLOWLY move the tractor forward. This should pull it free. I have done this a couple of times with success. Once fully apart, grease, grease, grease and re-assemble and you should be trouble free.

Make sure there are no shipping screws in it before you spend too much time pulling on it. Sometimes they come locked together with a few small screws through the plastic tube.

Thanks for the advice will look closer for screws and try again tonight.. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Make sure you pick up some extra shear bolts. You will probably need them if this is the first time you will mow your acreage. Don't ask how I know this /forums/images/graemlins/wink.gif I prefer to use the actual shear bolts, because I had a hardware store grade 2 (hasty replacement) bolt not shear and only bend. I didn't damage anything, but do not want to take any chances on the failure to shear ruining something.

I had a similar problem with a pto shaft not to long ago. Like others have said mine was stuck due to rust from sitting up a while. I had to use a little heat from a torch and alot of persuasion from a pickup truck to finally break it free. Also use alot of wd-40 to help loosen up the rust. If you try using the tractor be carful when backing with the shaft attached to the tractor. I tried using that method and pushed the shaft back to far on the tractor PTO. It took me an additional 30 minutes to get the shaft back off the tractor PTO shaft.

Good Luck

I don't necessarily recommend this solution, but I was desperate and it worked for me. I had a 50 HP Ford tractor at Grandpas, and sitting uncovered in the pasture for TWENTY YEARS was a brand new 6' rotary mower.

I brought it up from the pasture, checked the gearbox for oil, greased it, and tried to hook up the PTO. It was 20 Yrs stuck! No amount of penetrating oil seemed to help. Bashing it with a hammer wasn't working.

What I finally did was hook a come along to the pto shaft front half and the other end to the front axle of the tractor. (Mower was on the 3PH). I pulled on the come along as much as I could, then I'd go bash the front yoke with a hammer.

Finally, it gave way and came apart. More grease and it was good to go.

Like I say, I was desperate. Don't think I'd do that on my Bota!

I took the shaft off the mower tonight put penetratong oil down both ends?? Which end should move? the part tht attaches to the tractor or the part at the bushhog?? I like the come along idea.. I'll try it tomorrow.. I was going to try the hook up to a tractor a an attachment but my neighbor has his tractor in the shop and after taking at least 30 mins of backing up going forward Pulling my guts out to move the mower, I didn't want to take the mower off my 3 PH.. I am definantly going to order a Pats quick hitch before I go through that again..Thank for the ideas.. /forums/images/graemlins/smirk.gif
