OPERATINGTHETILLER
Thefollowing pagesprovide guidelinesto
using your tiller effectivelyand safelyin
various gardening applications. Besure
to read "Tilling Tips & Techniques" in this
Section beforeyou actually putthe tines
into the soil.
This is a CRT(counter-rotating tine) tiller.
Asthe wheels pull forward, thetines
rotate backward.
This createsan "uppercut" tine action
which digs deeply, uprooting soil and
weeds. Don't overloadthe engine,but dig
asdeeplyas possible on each pass. On
later passes,thewheels maytend to spin
in thesoft dirt. Helpthem along by lifting
up slightly on the handlebar(palm facing
up).
1. Follow the "Pre-Start Checklist" on the
previous page. Besurethat the wheels
are in the WHEELDRIVEposition.
2. Putthe Depth Regulator Leverin the
"travel" position (lever all the way down)
so that the tines are clear ofthe ground.
Usethis positionwhen practicing with
your tiller or when moving to or from the
garden. When you are readyto begin
tilling, you must move the Depth
RegulatorLeverto the desireddepth
setting (see"Tilling Tips & Techniques").
Checkthat the Anti-Reverse Stakeswivels
freely backandforth. Removeanyclogged
material on or around the stake.
