REVERSECLUTCHCONTROL
TheReverseClutch Control (C, Figure
3-1) controls the engagementof reverse
drive to thewheels and tines. The revers-
ingfeature isusedfor maneuveringthe
tiller only- neverengagethetines in
thegroundwhile goingin the reverse
direction.
Use extreme caution when reversing
or pulling the machine towards you.
Lookbehindto avoidobstacles.
Neverattempttotill in reverse.
Failure to follow this warning could
result in personal injury or property
damage.
ToOperatetheReverseClutchControl:
1. Putthe WheelGearLeverin the
ENGAGEposition (seethe "WARNING"
statementon previous page).
2. Stopall tiller motion by releasingthe
Forward Clutch Control levers.
3. Lift up the handlebarsuntil the tines
clearthe ground, look behindyou to avoid
anyobstacles,and then pull the Reverse
ClutchControl knob out. Thetines and
wheelswill rotate in a reversedirection.
4. Releasethe ReverseClutch Control
knob to disengage(stop) the wheels and
tines. All reversemotion will stop (the
enginewill continue to run).
Do not attempt to till too deeply too
quickly. Gradually work down to
deepertilling depths.
Placethe DepthRegulatorLever in the
"travel" position before starting the
engine. This position prevents the
tines from touching the ground until
youare readyto begintilling.
Failure to follow this warning could
result in personal injury or property
damage.
DEPTHREGULATOR
TheDepth Regulator lever(D, Figure3-2)
controls the tilling depth ofthetines. Pull
the leverstraight backand slide it up or
down to engagethe notched height set-
tings.
Figure3-2: DepthRegulatorLever,
The highest notch (leverall the way
down) raises thetines approximately
1-1/2 inches off the ground. This "travel"
position allows the tiller to be moved
without the tines digging into the ground.
Moving the lever up increasesthe tilling
depth. Thelowest notch allows a tilling
depthof approximately six to eight
inches,depending on soil conditions.
Forbestresults, alwaysbegintilling at
a veryshallowdepthsettingand gradu-
ally increasethetilling depth. Complete
details on using the Depth Regulatorare
found in the "Operation" Section of this
manual.
HANDLEBAR HEIGHT ADJUSTMENT

different settings. Set the handlebar
