Belt slipping on Troy Bilt tiller 8 hp

Got a 8 hp Troy Bilt rear tine tiller, tried to engage tiller, belt slipped, sprayed with belt dressing, worked great 5 minutes, slipping again, thinking about spraying again, if not any suggestions. Thanks

how old is the machine. either the belt is worn out or there's a pulley issue. can you post the machines model number along with the engine model.

The more belt dressing you put on it, the worse it will be, and you'll have trouble with new belts if it gets on them. If the belt is slipping, it either isn't tight enough or the belt doesn't fit the pulleys properly.

Throw away the belt dressing!! That stuff softens the belt making the belt dangerous as it WILL come apart while in use.
You need to buy a new belt for it. You also need to clean the pullies with BrakeKlean to remove the belt dressing residue before installing your new belt.

The small block that is at the bottom of the shift rod where the little bearing pops over to hold it in gear can be adjusted to tighten the belt. The procedure is described in your manual.

OK... no manual. If you look at the bottom of the shift rod, you will see a roller that rolls downward as you push the rod into gear. You will see that roller kinda hop over a small steel block attached to the tiller, and that is what holds the roller down to keep it in gear. With the engine off, everything in neutral, loosen the bolt on the back of the block and slide it down maybe 1/16" of an inch and retighten the bolt. 1/16" of movement accounts for 1/8" of belt length (both sides). Now start it up and try to shift in gear. If it takes a LOT of effort to get that roller past the block or it won't go past at all, you moved it too much, if the belt still slips, you didn't move it enough. If the block is all the way to the bottom of its adjustment and the belt still slips, then you need a new belt.
