If both Forward Interlock Levers are
releasedbefore first returning the
Wheels/Tines/PTODrive Lever to
NEUTRAL,the engine will stop.
IMPORTANT: The Forward Interlock
Levers are a safety control that stops the
engine should you lose control while
going forward and cannot shift into
NEUTRAL.
Wheel Speed Lever
Use the Wheel Speed Lever (C, Fig. 3-1)
to select one of three operating positions:
SLOW, FASTor FREEWHEEL.
• SLOW- Lever moved all the way down.
Most effective for normal tilling or for
low-speed transport.
• FAST- Lever moved all the way up.
Most effective for cultivating or for fast-
speedtransport.
•FREEWHEEL - Leverin betweenSLOW
and FAST(wheelswill roll freely). Used
whentransporting the machineon level
ground without engine power, and when
using stationary PTOattachments.
IMPORTANT: To avoid transmission
damage, always move Wheels/Tines/PTO
Drive Lever into NEUTRALbefore shifting
the Wheel Speed Lever.
IMPORTANT: When shifting into SLOW
or FAST, gently roll the machine forward
or backward to help fully engage the
wheel gears. When engaged, the wheels
will not turn unless the engine is running
and the Wheels/Tines/PTO Drive Lever is
engaged in FORWARDor REVERSE.
TineslPTO Clutch Lever
Use this lever (D, Figure3-1) to engageor
disengagepower from the transmission
PTOclutch to the tines or any PTOattach-
ment. This control has two operating
positions: ENGAGE and DISENGAGE.
•ENGAGE - Levermoved into detent slot
farthest from engine. Usethis position to
operatetines or other PTOattachments.
After shifting to ENGAGE, b riefly operate
machine in FORWARD to help fully
engagethe PTOclutch.
•DISENGAGE - Lever moved into detent
slot nearestengine. Usethis position to
disengagepower to tines or other PTO
attachmentsbeforetransporting, loading,
turning, or operating in reverse.
IMPORTANT: To avoid transmission
damage, always move the Wheels/Tines/
PTO Drive Lever into NEUTRAL before
shifting the Tines/PTOClutch Lever.
Depth Regulator Lever
Use this lever (E, Figure 3-1) to regulate
the tilling depth of the tines. This control
also has a TRAVELposition, which
enables transport with the tines off the
ground.
To operate the lever, lift up on the handle-
bars, pull the Depth Regulator Lever
straight back, and then slide it up or down
to one of the eight detent height settings.
The eight detent positions offer a range of
fine height settings. This enablesyou to
select the height that is most effective for
a particular condition. The top detent
position is the TRAVEL setting. Use the
second or third detent from the top for
shallow tilling and cultivating. Use the
other detents for deeper tilling and for
power composting.
To avoid personal injury,
always place the tines in the TRAVEL
position before starting the engine.
This prevents the tines from touching
the ground until you are ready to begin
tilling.
Handlebar Height Adjustment
Lever
Use this lever (F, Figure 3-1) to adjust the
handlebarsto one of two height settings.
1. To changethe height, hold the handle-
barswith one hand and loosenthe leverin
a counterclockwisedirection.
2. Move the handlebarsto one of the two
preset height settings.
3. Retightenthe lever.
NOTE: You can swap the positions of the
inside handlebar ratchets to change the
two preset settings by approximately four
inches higher or lower. See Section 2,
Step 2: Attach Handlebarfor detailed
assembly information.
