How do I repair/replace the Quick disconnect pin on the PTO shaft of a rotary mower (bush hog) ?

Will the pto engauge with out the brushhog hooked up to the pto . Can you turn the drive shaft on the brushhog when it is unhooked from the tractor is any thing bound up around the shaft for blade .if the tractors pto will ingage with out the hog hooked up i would say u may have a bearing locking up or something bound up under neath the hog if not bad bearing mor than l?kely

Have someone help you rock the tractor back and forth and see if it lets go ,if not jack up rear wheels and rock them back and forth.

Most PTO shafts are a square shaft inside of a square tube to allow for it to go in and out of itself as the mower goes up and down across the ground. You should be able to unhook from the tractor and the gearbox to remove it. In the USA we have farm stores that we go to for the U Joints and halfshafts and connectors to repair them. Some of the parts are also used on trucks so Truck Repair places also. Any parts house can get you a u joint if you bring them the old one to measure.There is also round shaft models but there has to be a slip joint in all of them so no to removing the gearbox off of the mower deck.

I'D CALL JOHN DEERE DEALER ASK FOR SERVICE MANAGER HE SHOULD HELP OR WILL GET YOUR ANSWER

pto is on the tractor, not on the bush hog, if it won't engage you have pto problems on tractor, needs to be serviced

Hi Lynn:
The speed of the PTO on every tractor I've owned has been directly related to engine RPM and there has been no other way to change it.
Did your bush hog work with it at one time? If it did, what has changed since then? That might give an indication of a possible fix. It may be that the tractor and bush hog are not compatible.

lift The brush hog up and place on blocks or other foundation that wont fall over. disconnect the power take off shaft from the tractor. Now look for two round openings in the middle of the deck one on ether side of the gear box (the thing on the brush hog that the pto shaft from the tractor hooks up to to make it spin there might be a slip clutch on the shaft but go to the box in the middle) Now turn the shaft till you see the blade nuts in the hole These could be castle nuts with a small carter pin locking them so they don't unscrew. Remove the pin and with a large socket set unscrew it from the bolt then knock the press fit bolt down and the blade will come off, do the same to the other blade if you need them both off. To put them back on use something under the blade and bolt to hold it up so you can start the nut then reverse the order and put everything back on. The blade bolt might be stubborn to get out just take something that fits through the access hole like a wood doll or long punch and drive the bolt down till it comes out as it is press fit and is jammed up to keep the bolt from turning, when putting it back on you will need to make it tight so the bolt can repress back in. Be Careful when reaching under to set the blade and bolt back in. There is not much you can mess up it is just a big nut and bolt Just make sure you put the blade on the way it came off if you do one blade or one at a time you can look at the other to see which way it goes.

I take help from online websites

Reading on line, I see your tractor has a PTO clutch. It must be slipping. It either needs adjusted or replaced. A slipping clutch disc will make a bad smell.
