Troybilt tiller help needed

Posted by buffalodz (My Page) on

I have an old Troybilt tiller that I inherited from my father-in-law (Horse I'm assuming since it has a 6hp engine) and am having belt problems. It appears the belts (2) are too big. I've measured them and they are around 21" but still won't drive the wheels and tines when tilling. I've adjusted the little cam where the shift handle is to tighten the belt tension for tilling and the belts still seem to slip. When I have the motor in the up position there is still slack in the belts. I've moved the cam that holds the shift lever down and it still has slack. I took them off and they appear to be in good shape. Is there anything else I can do other than trying a smaller belt? Possibly a 20" belt? This is a two speed tiller. I'm getting desperate to get my tilling done. Any help would be appreciated

Mine were slipping yesterday on the first use this year and then stopped slipping after awhile. And you say the roller is down on the cam with 1/4" of free space at the bottom?

It might be like mine with a PTO lever on the left rear that engages and disengages the tines.

I could move the cam down more but the shift lever is already down against the tines guard. Still a fair amount of belt play. The tines will turn but as soon as they contact the ground to till they stop. You can see that the belts aren't turning. When I turn the engine off and the motor is in the up/engaged position there is play in the belts. I don't have a PTO lever to engage the tines. When I shift the engine "up" with the lever the whels and tines turn in unison. There is not separate lever for just the tines. Everywhere I look for belts the sizes listed for the two speed are 21-22". That's what mine measure but I still have slack. I'm baffled.

I just went thru this a month ago!
And the answer was here on Gardenweb!
Here's the answer, sort of; NAPA 4L210.
They are shorter than the originals and work great, but on mine, so far, they don't allow the transmission to stay in gear. I have yet to try a stronger spring on the cam lever. Even so, it isn't too bad holding the lever down since the machine is so well balanced. Good luck!
By the way, I am also getting the carb rebuild kit from NAPA. Bad timing for me as I have never done this (rebuild a carb, thanks Youtube!) and needed to use the tiller, but once it is running it will do several other things around my work place.

I have a belt supplied by Troy about 20 years ago. It's brand new and I'll measure it tomorrow and get back here.

Bobby Miller your tiller was built between 7-1-75 to 1-1-76

In case you don't have a copy of the owner's manual for that model - the link below opens up a 180 page PDF copy of the original from '78 -'79. I don't suppose it had changed much in 2-3 years.

Here is a link that might be useful: Troy-Bilt Horse Roto Tiller Manual

Mine is a 1982 model with the PTO and uses only one belt. There are two pulleys for low and high speed and you can only choose one.

My belt is 22 1/2" X 1/2" wide X 3/8" thick. It's new.

where on the machine do i find the model number and serial number? ... we have a 1984 (?) troy built/garden way that belonged to my father-in-law. ... i can find "part #2412 (6/84)" marked on it; and "Kohler 8" ... ... but not the model or serial number.

I haven't looked at mine, but generally, oil seals can be pulled out from the outside. You can use a screwdriver or a real seal puller.
