Keep away from rotatingtines. Rotating
tines will cause injury.
Stoppingthe Engineand Tiller
1. To stop the wheels and tines, release
the Forward Clutch Bail (all models) or the
ReverseClutch 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
The following 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 is a traditional "Standard-
Rotating-Tine" (SRT) tiller with forward
rotating tines. It operates completely dif-
ferently from "Counter-Rotating-Tine"
(CRT) tillers or from front-tine tillers.
1. Follow the Pre-Start Checklist at the
beginning of this Section. Be sure that the
wheels are in the WHEELDRIVEposition.
2. Move the Depth Regulator Leverall the
way down, so that the tines clear the
ground. Use this position when practicing
with the tiller and when traveling between
tilling sites. Beforeactually tilling, move
the lever to the desired depth setting (see
Tilling Tips & Techniques).
3. Start engine and allow it to warm up.
Then put throttle in "FAST" setting.

moving forward.
4. For forwardmotion of the wheels and
tines:
(a) Pull Forward Clutch Bail (Fig. 4-1) up
against handlebar. Releasebail to stop
forward motion of wheels and tines.
(b) When tilling, relax and let the wheels
pull the unit while the tines dig. Walk
behind and a little to one side of the
unit. Use one hand, yet keep a 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 causes
the tines to try and propel the tiller.
Do not push down on the handlebars to
try to make the tiller till more deeply.
This preventsthe wheels from holding
the tiller back and can allow the tines
to rapidly propel the tiller forward,
which could result in loss of control,
propertydamage, or personalinjury.
5. For reverse motion of the wheels and
tines (Models 634F/634B only):
(a) Look behind and exercisecaution when
operating in reverse. Do net till while
in reverse.
(b) Stop all forward motion. Lift handlebar
with one hand until tines are off the
ground and then pull ReverseClutch
Control knob out (see Fig. 4-3). To
stop reversing, let go of ReverseClutch
Control knob.

behindwhen movingin reverse.
6. To move the Model 630B in reverse for
short distances:
(a) ReleaseForward Clutch Bail. Then lift
handlebar until tines are off the ground.
(b) Swing the handlebarto the left so the
right wheeltakes a "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
placethe two wheels in FREEWHEEL.
7. To Turn the Tiller Around:
(a) Practice turning the tiller in a level,
open area. Be very careful to keep
your feet and legs away from the tines.
(b) To begin a turn, lift the handlebarsuntil
the tines are out of the ground and the
engine and tines 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.
