TINE OPERATION (See Fig. 6)

•Squeeze tine control to handle.

TILLING

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

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. 7)

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.
