Troy-Bilt tiller question

I have a question for the Troy-Bilt experts out there. I have a 20 year old Troy-Bilt tiller, one of the larger models powered by an 8 HP Tecumseh engine. I am having problems with the belt drive. I cannot get the control lever adjusted to it stays in the down position and the drive belt tight. I have played with the spring and adjusted the ramp up and down.

I am thinking I may have a wrong belt or just plain do not know how to adjust it. Any suggestions?

How old are the belts??? They do wear out over time and they are a real pain to replace. Not 100% sure what your asking since you do not explain things well. If your saying when you push the lever down which in turn tightens up the belt then you have one of a few problems. The spring is getting weak I know the one on my 1972 model one has that problem and I have a boogie cord on it for extra hold. Or your linkage maybe binding up and not moving like it needs to so that the wheel on it locks down. Also that wheel need to spin a little when put down.
 
You may need a new belt adjusting block. It's item No.19 in my parts manual. Your local Troy dealer should have them. I've taken several pictures of the spare block I have. I use Gates greenstripe belt No.6822 they're made to withstand the clutch and declutching. Hal

In my experience, the suggestions by both old and El Toro could well be your problem. On the other hand, on my Troybilts I've found that the belts wear out more frequently than the hardware.

If I understand your problem correctly, I've found that the inability to tighten the belts properly has been because the belts have stretched beyond the adjustment capacity.

I've learned to start there.

Best of luck.

I've been down that road with my '81 7-HP Troy-Bilt Horse. Sometimes it takes more than one try to get the belt adjustment just right.
If you still have the problem after adjustment according to the manual as posted, you might need to closely inspect the roller for out-of-roundness or wear down and that it rotates freely.

Check the sliding adjustment cast part on its lower angled end for flatness where the roller moves to in the "Go" position of the shifter. The roller may have worn a depression where it contacts the adjuster due to small movements during operation caused by belt rotation.
My spring did get weak so I "farmerized" it with a second spring from the junkbox for some added tension.
 
I've haave the same belt on my tiller since 2006 when I installed a new engine. It's the Gates 6822 belt They're around $15.00 give or take a dollar or two.

Keep that area where the rollers roll up and down on that adjusting block well lubed also on the pins when you raise and lower the engine. I drilled and tapped mine and installed alemite grease fittings with 1/4-28 thread. Hal

I bought a very well used and abused Troy-Bilt Horse model at an auction 12 years ago. It has the 8 horse Briggs I/C engine. I replaced the belts when I purchased it, made a few repairs, and used the heck out of it for 12 years now. Just yesterday I had to replace the gasket between the carburetor and intake tube. Other than that, I've never had a problem.
 
Those parts are still available from Troy Built, I put new ones on when I changed the motor out.
 
Yes to all of the good advice. When you mess with these adjustments go for the roller the block, belts, and the reverse piece. "drive disk" You will find that the notch in the block is worn and or the roller too. Very good little machines. They are now part of MTD if I am correct. Something like three or four years now.
