Operation
CONTENT OF SECTION
A brief description of the rotary tiller controls,
followed by the basic operating procedures, is
given In this section to help you get to know your
rotary tiller and how to operate it safely and
efficiently.
ROTARY TILLER CONTROLS
The rotary tiller is operated using controls on the
tractor. Figure 5 shows the locations, names, and
functions of these controls. The control names
given in figure 5 are used throughout the manual.

OPERATING PROCEDURES
The rest of this section tells you how to operate
your rotary tiller. The directions assume that both
the rotary tiller and tractor work properly. If not,
refer to the troubleshooting sections of this manual
and the tractor manual.
CHECKS BEFORE STARTING
The checks listed below should be performed
before each use of the rotary tiller.
A WARNING
Before attempting to inspect, adjust, or
service the rotary tiller make sure the
REAR CLUTCH switch is off, the engine
stopped, the key removed, and tiller is
lowered to the ground. .
1. Read this manual. Read the tractor operator's
manual. Be sure you know safety precautions
and locations and uses of operating controls.
2. Check the rotary tiller to insure that it is
properly installed on tractor. Be sure that all
safety guards are in place and that all nuts,
bolts, and spring clips are secure.
3. Refer to Normal Care section of this manual
to determine and perform any needed care for
the rotary tiller. Do the same for the tractor.
4. Clear the area you intend to till to be sure
that it is free of all items that may be caught
in or thrown by the rotary tiller.
TRACTOR AND TILLER OPERATION
The tractor supplies both the power and forward
motion for the rotary filler. Therefore, tractor
operation is vital to proper rotary tiller operation. -
Details for rotary tiller operation are given in para-
graphs that follow. Read all of these paragraphs.
Then read the general operating procedure for
tractor operation with attachments given in the
tractor manual before attempting to use the rotary
tiller.
Raising and Lowering the Rotary Tiller
Use the rear lift control (item A, figure 5) to raise
and lower the rotary tiller. Pull this control rear-
ward to raise the tiller; release it and allow it to
return to its hold position to keep the tiller raised.
To lower the tiller, push the rear lift control
forward to its float position.
A\ CAUTION
The rear lift control must be in its float
position when you are tilling. The float
lockout pins must also be in the float
position. Otherwise, the tiller can propel
the tractor.
Operation
Steering with Rotary Tiller Installed
The weight of the rotary tiller behind the tractor
reduces weight on the front wheels. Use of the
front counterweight is recommended to restore the
normal turning ability of the tractor. Even with the
weight installed, avoid “jack-rabbit” starts and ad-
just the tractor speed to fit the condition of the
surface on which you are traveling.
Turning or Backing with Rotary Tiller
Before backing up the tractor or turning the trac-
tor sharply, always raise the tiller until it is clear of
the ground. Otherwise, the tiller can be damaged.
Transporting the Rotary Tiller
When you use the tractor to transport the rotary
tiller to and from work areas, the rotary tiller
should be fully raised. Also be sure the REAR
CLUTCH switch is set to its off position to dis-
engage the tiller.
Engine Speed for Tilling
Operate the engine at 3/4 to full speed for normal
tilling. Full engine speed will be necessary when
tilling depth and ground conditions require full
engine power.
Tractor Speed for Tilling
The tractor speed affects the tilling depth and the
size of the soil particies. The best speed is deter-
mined by the soil conditions and land contours.
For most conditions, the best speed is obtained
in first gear. You may be able to use second gear
in soft, loose soil. In either gear, adjust the hydro-
static control for the desired results.
Stopping the Rotary Tiller
To stop the rotary tiller while it is in operation,
flip the REAR CLUTCH switch (item B, figure 5)
down and stop the tractor. Do this immediately if
you strike rocks that jam and stop the tines.
NOTE
After striking a foreign object, stop the
‘engine, disengage PTO, remove ignition
key, and lower tiller to the ground.
Thoroughly inspect the rotary tiller for
any damage before restarting.
Shield Position
The shield (item A, figure 6) prevents throwing of
loosened soil and rocks. The rear of this shield
should rest on the ground when the tiller is at the
desired depth. To adjust the shield height, place
different chain links over the hook (item B). For
finer adjustment, you can also twist the chain.
Figure 6. Shield and Skid Shoes
Starting the Rotary Tiller
To start the rotary tiller into operation, stop
the tractor and proceed as follows:
1. While tiller is raised so tines clear ground, set
REAR CLUTCH switch to its on position.
2, Push rear lift control fully forward to its float
position to lower rotary tiller.
3. When tines have dug down and skid shoes are
resting on ground, start tractor forward.
Adjust tractor speed as you proceed to keep
skid shoes on the ground.
Tilling Depth
You will want to till to a depth that suits the seed
you will plant. As a rule, till at least 2 inches (50
mm) deeper than the normal planting depth for the
seed. The usual planting depth for corn, as an
example, is 2 to 3 inches (50 to 76 mm). Using the
rule above for this example, till the soil to a depth
of 5 inches (127 mm) or more.
If you till too deeply in a single pass, the soil tex-
ture will be coarse. The problem can be avoided
by making a number of passes over the same area.
Till to a shallow depth on the first pass. Then
increase the depth on each additional pass until the
seedbed has the proper depth and texture.
To control the tilling depth, raise or lower the
rotary tiller by adjusting the skid shoes (item С,
figure 6). Make this adjustment as follows:
1. Stop tractor, set parking brake, and be sure
REAR CLUTCH switch is off.
2. Raise rotary tiller to its transport position.
3. Stop engine and remove ignition key.
4. Remove spring clip and pin (item D) and slide
skid shoe up or down to desired height. Then
reinstall pin and spring clip to secure skid
shoe. Be sure both skid shoes are set to same
height.
Normal Care
CONTENT OF SECTION
Your rotary tiller was designed and built to provide
years of service with only minor care. This care,
however, must be performed to keep it In good
operating condition and to avoid costly repairs.
This section shows you how to provide the neces-
sary care.
SCHEDULED CARE
The only care required for the rotary tiller on a
regularly scheduled basis is lubrication. The rotary
tiller must be lubricated as shown in figures 7 and
8 before the first use and after every 25 hours of
operation.
A Maintenance Record (figure 14) is provided to
help you document all operating hours and main-
tenance repair actions.
NORMAL STORAGE
To protect your rotary tiller, store it in an enclosed
dry area. Clean the tines and body of. the rotary
tiller to remove excess dirt and plant matter. This
can be done easily with a hose.
OFF-SEASON STORAGE
When the rotary tiller is to be stored for 30 days or
more, take precautions as follows: |
1. Remove rotary tiller from tractor.
2. Clean the entire tiller, including the tine
assemblies.
3. Coat the tines with a light film of grease or
oil. Coat all other bare metal surfaces with a
good quality paint (obtainable from your

Adjustments
CONTENT OF SECTION
This section tells you how to adjust the rotary
tiller to keep it operating efficiently. Normally, the
adjustment procedures should be performed only
to correct problems.
AN WARNING
To. avoid serious injury, perform adjust-
ment procedures only when the tractor
engine is stopped. Always remove the ig-
nition key before beginning the adjust-
ment procedures to prevent accidental
starting of the engine. Be sure tiller is
lowered to the ground.
ADJUSTMENT PROCEDURES
Chain Tension
‘The capscrews which hold the chain tension rollers
are mounted in slots (item B, figure 12). Because
the rollers wear with use, the capscrew positions
must be adjusted to maintain chain tension. Once a

mercial purposes, adjust the chain tension as
follows:
1. Loosen, but do not remove, nut (item A).
2. Use two box wrenches as shown to hold the
nut and its capscrew. Push both box wrenches
to the rear as you retighten the nut.
3. Repeat steps 1 and 2 at the nut over the slot
(item B).
Slip Clutch
The slip clutch must drive the tiller during normal
operation. Yet, it must be adjusted so it slips when-
ever the tines strike hard objects. By slipping, the
clutch prevents damage to the tiller drive and
PTO. When the slip clutch becomes too hot to
touch from slippage during normal operation, re-
adjust the clutch as follows:
NOTE
Do not overtighten the slip clutch. If the
clutch is too tight, it cannot protect the
tiller drive and PTO.
1. Remove six screws that secure crossdrive shaft
cover (figure 13). Then remove cover.
2. Hold capscrew (item A) while tightening lock-
nut (item B). Tighten locknut only until
spring 1s fully compressed. That is, until the
locknut suddenly becomes harder to turn.
3. Repeat step 2 to tighten the other five lock-
nuts.
4. Hold capscrew while loosening each locknut
(item B) exactly one-half turn.
5. Reinstall drive shaft cover on tiller. Secure
it by installing and tightening the six screws
removed in step 1.
