4. Tines/PTO Clutch Lever 5. Depth Regulator Lever
This lever is located on the
left side of the transmission, just
forward of the tiller tine hood.
There are two operating positions:
“ENGAGE” and “DISENGAGE”.
See Photo 2-6.
When you move the lever to the
“ENGAGE” position, it moves the
“dog” clutch on the PTO Power ^
Unit drive shaft backward until it
engages the “dog” clutch on the
tine attachment drive shaft. (If the
tines are removed and replaced
with a PTO driven attachment, the
“dog” clutch on the power unit will
engage with the “dog” clutch on
the PTO driven attachment). Engine
power will then be applied to the
tines or PTO driven attachment
when the separate Wheels/Tines/
PTO Drive Lever is engaged in
“FORWARD” or “REVERSE”.
In the “DISENGAGE” position, the
“dog” clutches are disengaged,
and power will not be applied to
the tines or PTO attachment.
When operating the tiller, the
“DISENGAGE” position allows you
to stop the tines while the sep­
arately controlled wheels continue
to rotate. You should use this fea­
ture whenever you are transport­
ing, loading or unloading, turning
around, or backing the tiller up.
You should also disengage the
lever before towing or transporting
any attachment.
When the tines are removed and
a PTO driven attachment that oper­
ates from a stationary position is
installed, the “ENGAGE” position
allows you to power the attachment
while the wheels on the PTO Power
Unit are not moving.
Always place the Wheels/Tines/
PTO Drive Lever in “NEUTRAL” be­
fore shifting the Tines/PTO Clutch
Lever. Doing so will help prevent
damage to the transmission that
could occur if you try to engage or
disengage the separate drive shaft
clutches while they are turning
under power.
To operate the Tines/PTO Clutch
Lever:
A. Put the Wheels/Tines/PTO Drive
Lever in “NEUTRAL”.
B. Pull the Tines/PTO Clutch Lever
out and then slide it into the “EN­
GAGE” or the “DISENGAGE” slot.
C. After selecting the “ENGAGE”
position, do not immediately shift
the Wheels/Tines/PTO Drive Lever
into “REVERSE”. Always use “FOR­
WARD” first, to help align the drive
shaft clutches inside the transmis­
sion. NOTE: The lever should move
easily. If it doesn’t, then the “dog”
clutch inside the PTO Power Unit
transmission may need to be lubri­
cated. See “Tiller Lubrication” in
Section
6
of this Manual.
A
CAUTION
TO AVOID PERSONAL INJURY OR
DAMAGE TO EQUIPMENT:
• Always disengage the Tines/
PTO Clutch Lever before reversing,
transporting, turning around, or
loading or unloading the tiller or
PTO Power Unit.
• Do not attempt to stop the tines
or any PTO driven attachment by
disengaging the Tines/PTO Clutch
Lever. Always put the Wheels/
Tines/PTO Drive Lever in "NEU­
TRAL” to stop all motion.
• Read the Owner/Operator Man­
ual provided with any attachment
before attempting to operate the
attachment.
This lever is located at the rear
of the tine hood—see Photo 2-7. It
is used to regulate the tilling depth
of the tines.
To operate the lever, pull it straight
back and then slide it up or down
to any of eight different notched
settings.
When the lever is moved all the
way down until it engages the high­
est notch in the lever, it places the
tines in the “TRAVEL” position. In
this position the tines will clear the
ground by approximately
2
-inches,
allowing you to transport the tiller
without the tines—which should be
disengaged—scraping your lawn
or driveway.
For shallow tilling and cultivat­
ing, you should place the lever in
the second or third notch from the
top. These positions will allow the
tines to dig just a few inches into
the soil. The remaining notches
are used for deeper tilling (up to
8
-inches deep, depending on the
soil conditions), and for turning
under organic matter.
Further details regarding the
proper use of this lever will be
found in Section 4 of this Manual
(see “Tilling Depths”).
A
WARNING
To help 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.
