Tips for improving tilling when using your Kmart rear-tine tiller

Worn or damaged tines, broken tine shaft clevis pins, a worn drive belt, a faulty transmission, a problem with the clutch cable, improper depth-stake setting or bad soil conditions can cause a tiller to do a poor job turning the soil.

The soil must be moist enough that it forms a ball when you squeeze it in your hand, but dry enough that the ball falls apart when dropped. Check soil conditions and water the area that you're tilling if the ground is too dry. Let the ground dry out if soil is too wet.

Check the depth stake setting and adjust it for the type of soil you're cultivating. Lower the depth stake to till at a 1-inch depth when using the tiller on soil for the first time or when breaking up hard soil. Also use the 1-inch depth setting to break up sod for shallow cultivation. Raise the depth stake to till loose soil and for deep cultivation.

Check the condition of the tiller tines and replace worn or damaged tines.

Troubleshooting your Kmart rear-tine tiller when its engine runs rough or misfires

If your tiller engine isn't running smoothly, cleaning or replacing the carburetor, tuning up the engine or replacing bad gas may fix the problem.

If you left gas in the tank during the winter without adding fuel stabilizer, drain the tank and fill it with fresh gas. Add fuel stabilizer to gas to keep it fresh during the off-season.

Stale fuel can clog the carburetor, so clean and rebuild the carburetor if the tiller continues to run rough or misfire after replacing the gas in the fuel tank. Replace the carburetor if it's too clogged to clean.

Tune up the tiller engine by replacing the spark plug and oil. A dirty spark plug won't ignite the fuel properly. Old oil won't lubricate engine parts well so the engine idles roughly because the piston or pistons won't move smoothly through the cylinder.
