I just got a 5' KK rotary tiller and the pto shaft fits onto the tractor just fine with the button lock. The other end doesn't want to slide all the way onto the tiller gearbox drive shaft. It only goes half way and is unable to slide completely on. Is there supposed to be a push button lock on that side of the pto shaft as well? There is just a bolt. Is the bolt the source of the poroblem? Thanks!

You checked for a piece of post or rock stuck in the tines?

You should be able to turn the PTO shaft by hand. Suggest you disconnect the PTO shaft from the tractor and make sure the problem is the tiller.

The tiller end of the pto shaft has both a slip clutch and a shear pin to protect the gear box and tine shaft drive gear. See attachment.

If you are unable to turn the PTO shaft by hand with it disconnected from the tractor then likely there is something jambed in the tines or internal damage to the gear box or tine shaft gear drive.

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.

My motor was turning but the flex shaft wouldn't. I took the flex shaft loose and spun it inside. Works fine now.

are you sitting in the seat or have you jumped the safety switch under the seat before you engage the PTO I believe our tractors use an electric solenoid to apply hydraulic pressure to a wet clutch inside the trans axle I would think it would be OK with your chipper I have a 450 tiller that was built for the older 400 models 425 445 455 that I now use with my 2210 If I hit a large root or stone when using it with my old 445 it would stall the tractor at full power. Now with the 2210 it will actually slip the clutch on the tiller s PTO shaft I think the correct approach would be to increase your RPM s gradually or start increasing the power just as you trip the PTO switch. You want enough RPM s to create enough hydraulic pressure to run the PTO circuit so that you don t slip the wet clutch anymore than necessary and you want the RPM s low enough so that you don t shock the mechanical systems too severely at start up
Let me know how it works

It doesn't attach anywhere, that's why it popped out. It should just fit in a recess, pushing the lock button outward.

Sounds as if you might have destroyed the gearbox or cooked the internal clutches or both....nothing to do but disassemble the gearbox to find out...you may have a broken gear tooth or teeth jamming the pinion...the FIX may be more expensive than the cost of a new tiller...call Tractor Supply to see if replacement parts are even available...sorry to be the bearer of such bad news... ;-(

USE SAY A BROOM STICK AND ON THE OUTSIDE ON THE DECK YOU CAN USE IT LIKE A STETHOSCOPE AND PUT IT TO YOUR EAR AND LISTEN TO DIFFERENT SPOTS ON THE DECK TO HELP YOU ZERO IN ON THE CULPRIT .. IF'N I WAS ANY HELP VOTE FOR ME ...THANKS.. JAY

Grasp the chuck and twist the sleeve counter clockwise and pull up.It will come off. To replace the chuck slide it back onto the drill shaft, grasp the chuck collar, twist it counter clockwise and push down on it, it will slid back onto the shaft and lock into place.

At least once a year back the clutch bolts out at least 3 turns and engage PTO at operating speed a couple times.Once thats done turn bolts back in the same amount of turns.By doing this you burnish the disc's and prevent them from rusting/seizing together with the plates.

slide the orange on/off switch all the way back then push in the black button the switch slides over. This will lock the shaft-then use small wrench provided w/ tool to turn the collet nut
