Stoppingthe Engineand Tiller
1. Tostop the wheels and tines, releasethe
Forward Clutch Bail (all models) or the Re-
verse Clutch Control (Models 634F and
634B) -- whichever control is in use.
2. To stop the engine, put the ignition
switch and/or the throttle control lever in
the "OFF"or "STOP" position.
OPERATING THE TILLER
Thefollowing operating instructions pro-
vide guidelines to using your tiller effec-
tively and safely. Be sure to read Tilling
Tips & Techniques in this Section before
actually putting the tines into the soil.
NOTE:This isa traditional "Standard-Ro-
tating-Tine" (SRT) tiller with forward ro-
tating tines. It operates completely
differently from "Counter-Rotating-Tine"
(CRT)tillers or from front-tine tillers.
1. Follow the Pre-Start Checklist at the
beginning of this Section. Besure that the
wheels are in the WHEEL DRIVEposition.
2. Move the Depth Regulator Leverall the
way down, so that the tines clear the
ground. Usethis position when practicing
with the tiller and when traveling between
tilling sites. Before actually tilling, move
the lever to the desired depth setting (see
Tilling Tips & Techniques).
3. Start engine and allow itto warm up.
Then put throttle in "FAST"setting.
4. For forwardmotion of the wheels and
tines:
(a) Pull Forward Clutch Bail (Fig. 4-1) up
against handlebar. Releasebail to stop for-
ward motion of wheels and tines.
(b) When tilling, relax and let the wheels
pull the unit while the tines dig. Walk be-
hind and a little to one side of the unit. Use
one hand, yet keepa light--but secure--
grip on the handlebar (while keeping your
arm loose). See Fig. 4-2. Let the unit
move at its own paceand do not push
down on the handlebarsto try and force
the tines to dig deeper --this takes weight
off the wheels, reduces traction, and caus-
es the tines to try and propel the tiller.
WARNING:
Do not push
down on the handlebarsto try
to make the tiller till more
deeply. This preventsthe
wheels from holding the tiller
back and canallow the tines to
rapidly propel the tiller forward,
which could result in loss of
control, property damage, or
personal injury.
5. For reverse motion of the wheels and
tines (Models 634F/634B only):
(a) Look behind and exercisecaution when
operating in reverse. Do not till while in
reverse.
(b) Stop all forward motion. Lift handle-
bar with one hand until tines are off the
ground and then pull Reverse Clutch Con-
trol knob out (seeFig. 4-3). To stop revers-
ing, let go of ReverseClutch Control knob.
(b) Swing the handlebarto the left so the
right wheel takesa "step" backward. Next
swing the handlebarto the right so the left
wheel"steps" backward. Repeatas needed.
(c) If longer distances need to be covered
in reverse,shut off the engine, then place
the two wheels in FREEWHEEL.
7. To Turn the Tiller Around:
(a) Practice turning the tiller in a level,
open area. Be very careful to keepyour
feet and legs away from the tines.
(b) To begina turn, lift the handlebarsuntil
thetinesare out ofthe groundand theengine
andtines are balancedoverthe wheels (Fig.
4-4).
(c) With tiller balanced, push sideways on
handlebar to steer in direction of turn (Fig.
4-5). After turning, slowly lower tines into
soil to resume tilling.
