OPERATINGTHE TILLER

Thefollowing operating instructions pro-

vide guidelines to using your tiller effec-

tively and safely. Besure to read Tilling

Tips & Techniquesin this Section before

actually putting the tines into the soil.

This is a "Counter-Rotating-Tine" (CRT)

tiller. It operatesdifferently from "Stan-

dard-Rotating-Tine" (SRT)tillers. Asthe

wheels pull forward, the tines rotate back-

ward, creating an "uppercut" action which

digs deeply, uprooting soil and weeds.

1. Followthe Pre-Start Checklistat the be-

ginning of this Section. Besurethat the

wheelsare in the WHEELDRIVEposition.

2. Movethe DepthRegulator Lever all the

way down, so that thetines clear the

ground. Usethis position when practicing

with the tiller and when traveling between

tilling sites. Beforeactuallytilling, move

the lever to the desired depth setting (see

Tilling Tips & Techniques).
