Leaking tine shaft - Troy-Bilt Troybilt Horse 6, 7 And 8 Hp Tiller Reverse Disc

The PTO unit must be damaged.

You have not shared which model and make of tiller you have, but many of them have a set screw or two holding each tine on.
You would need to loosen the screws, and maybe polish the shaft with sandpaper and oil it to get each tine off in order.
Some tillers use a different method of tine installation, since this can be patented or trademarked.
For example, some have the tines permanently attached to the shaft, so the whole shaft must be replaced as a unit.
God bless your efforts.

-Check the locking bolt that hold the tine shaft to the main shaft. Possibly it's broken. If so replace new bolt. you should be good to go again.


Good Luck

You could try putting the tiller to use, preferably where it will have to work hard to till the ground it unsuccessful you may need a torch and some good old fashion luck to loosen tines from shaft. Now consider this; if the bearings are worn so that the shaft is loose new seals will not hold up and you will risk doing further damage to the worm gear located on rear shaft and possibly other damage to your transmission from contaminated oil.

IF THIS IS A WALK BEHIND TILLER OR FRONT TINE TILLER. THERE SHOULD BE PINS OR BOLTS HOLDING THE TINES ON THE DRIVE SHAFT REMOVE THESE AND PULL THE TINES OFF THE TILLER. THEY MAY GIVE YOU A HARD TIME GETTING THEM OFF SO DON'T GIVE UP. ONCE YOU GET THE TINES OFF YOU SHOULD SEE THE SEALS YOU CAN POP THE OLD ONES OUT WITH A SCREW DRIVER CLEAN OUT THE SOCKETS WHERE THE NEW SEALS WILL GO REPLACE THE NEW SEALS GENTLY WITH A SMALL HAMMER TAPPING THEM IN EVENLY AND TRY NOT TO BEND THE SEAL

I had similar problem recently with 2007 Huskee MTD series 410. The shift assembly bent and couldn't move the clutch collar all the way over on the drive shaft.

Your worm shaft or tine shaft and gear assembly are probably shot. Welcome to the club. Long live American manufacturing.

on my pony the disc came off when i removed all of my tine shafts. then i pulled the old seals out an drove the new ones in

sounds like the shaft is either bent,or the inside diameter is worn and the shaft tube needs to be replaced.
