How do I tighten a belt on a troybilt Tecumseh rear tine tiller?

That's tricky... some of the small TB will not free wheel and either have to be "drug" from place to place or start up and drive it. Some allow to freewheel by pulling the pins on the wheel hubs, pushing the wheels "in" and reinstalling the pin. This allows the hub to "freewheel" on the axle and the pin just keeps the wheel from falling off. Hope this helps.

scans from old manual it should be the same

The ones I have owned had a 4HP Tecumseh on them but I think some of the real old ones might have had a 3 1/2 HP Tecumseh.

its always best to put a line on the bowl, to the bowl housing. ( i scratch mine in with a nail). then when you put it on, match 2 lines. iit may be possible float is stuck up like some woman i use to no, lol... but anyways, if one side of the bowl is deeper, (deeper side) has to go directly acrossfrom the float hinges.. i hope this helps....

Just bought a 1973 Horse model and it has this problem to the extreme! Fast, slow, shallow, deep, makes no difference. Did you ever get a solution?

Sounds like it could be a coil breakdown.

cold be broken centrifugal mechinism in side the crank case, or your lever is loose on the shaft

make sure you cleaned the main jet and low speed jet good and make sure your needle and seat are in good condition some time the seats swell up do to bad gas. there for no gas gets through the seat and make sure your gas is clean w no water, if this isnt a needle and seat carb use regular wire and clean it good.

Have you adjusted the locking cam for forward. This cam is held in place with one bolt. The further you move it down the tighter it will make the belt

MAKE TWO PASSES SET THE DEPTH GUIDE SO IT JUST BREAKS THE GROUND, DON'T TRY TO DO IT ALL AT ONCE. SOON AS THE GROUND IS LOOSE IT WILL DIG MUCH BETTER.. IT SHOULD HAVE A FORWARD AND REVERSE FOR THE TINES, GEARS FOR FORWARD REVERSE DRIVE

You can check the linkage that links the governor to the carb. If that is fine then you can check the fuel line for a blockage, the carburetor for debris, and if that is fine then you may want to try sanding the rust off the magnet (on the fly-wheel).

Hi there kimberly,

Here's what you need to do.

• Make sure the depth stake (behind the tines) is up as high as it will go. This will allow the tines to go deeper.
• Fire it up. Set the tine rotation to reverse (more mixing and twisting.
  
• Make sure the tines are actually turning, Each side is held in place with a shear pin. In case something binds the blades, this pin breaking will save the drive train
  
• Note how the tiller is balanced. Wheels in the middle. You can tilt it forwards or backwards.
  
• Tilting forward allows the wheels to gain traction and move the unit forward
• Tilting Backwards allows the tines to dig in. If the surface is too hard, Press down with your body weight. It will dig through.
• 
  

I hope this work out for ya

Best regards
Mike
