HOW TO  USE YOUR TILLER

Know how to operate all controls before adding fuel and oil 
or attempting to start engine.

The operation of any tiller can result in foreign objects thrown into the eyes, which can result 
in severe eye damage.  Always wear safety glasses or eye shields before starting your tiller 
and while tilling.  We recommend a wide vision safety mask for over spectacles or standard 
safety glasses.

STOPPING (See Fig. 5)

TINES

•     Release forward tine control to stop forward move-

 ment.

•     Release reverse tine control to stop reverse move-

 ment.

ENGINE

•      Move throttle control to “STOP” position.
•      Never use choke to stop engine.

TILLING

The speed and depth of tilling is regulated by the position 
of the depth stake and wheel height.

The depth stake should always be below the wheels for 
digging.  It serves as a brake to slow the tiller’s forward 
motion to enable the tines to penetrate the ground.  Also, 
the more the depth stake is lowered into the ground the 
deeper the tines will dig.

DEPTH STAKE (See Fig. 6)

Adjust depth stake by removing the hairpin clip and clevis 
pin.  Change depth stake to desired position.  Replace the 
clevis pin and hairpin clip.
•         For normal tilling, set depth stake at the second or third 

hole from the top.

WHEELS (See Fig. 6)

Adjust wheels by removing the hairpin clip and clevis pin.  
Change wheel position.  Replace the hairpin clip and clevis 
pin. 
•     For normal tilling, set wheels at the second or third 

hole from the top.
