OPERATION
TO THE NEW OPERATOR OR OWNER
The Buhler Farm King 65 Series Rotary Tiller is a machine that combines the primary
and secondary tillage operation into one machine. It breaks up the soil and prepares
the seed bed in one pass. Rotational power to the rotor is provided by the tractor PTO.
Be familiar with the machine before starting.
It is the responsibility of the owner or operator to read this manual and to train all
other operators before they start working with the machine. Follow all safety
instructions exactly. Safety is everyone's business. By following recommended
procedures, a safe working environment is provided for the operator, bystanders
and the area around the work site. Untrained operators are not qualified to
operate the machine.
Many features incorporated into this machine are the result of suggestions made by
customers like you. Read this manual carefully to learn how to operate the machine
safely and how to set it to provide maximum field efficiency. By following the operating
instructions in conjunction with a good maintenance program, your Tiller will provide
many years of trouble-free service.
MACHINE COMPONENTS
The Buhler Farm King 65 Series Rotary Tiller consists of a rotating drum that is
equipped with bent blades for breaking up and leveling soil. The blades are turned
through the soil while the machine moves over the working area. A Drag Shield is used
to maintain a level seedbed. Rotational power to the drum is provided by the PTO on
the tractor. The power is transmitted through the gearbox in the center of the machine
to the chain drive down the side. The A-frame can be moved to offset the machine.

MACHINE BREAK-IN
Although there are no operational restrictions on the Tiller when used for the first time, it
is recommended that the following mechanical items be checked:
A. After operating for 1/2 hour or after completing 1/2 acre:
1. Check all nuts, bolts and other fasteners. Tighten to their specified torque
level.
2. Check that the blades are in good condition and bolted securely to the
rotor.
3. Check the oil level in the gearbox. Add as required.
4. Check that the PTO driveline shield turns freely.
5. Lubricate all grease points.
B. After operating for 5 hours and 10 hours:
1. Repeat items 1 through 5 of Section A.
2. Then go to the regular service schedule as defined in Section 5.
PRE-OPERATION CHECKLIST
Efficient and safe operation of the Rotary Tiller requires that each operator reads and
understands the operating procedures and all related safety precautions outlined in this
section. A pre-operation checklist is provided for the operator. It is important for both
personal safety and maintaining the good mechanical condition of the Tiller that this
checklist is followed.
Before operating the machine and each time thereafter, the following areas should be
checked off:
Lubricate the machine per the schedule outlined in the Service and Maintenance
Section.
Use only a tractor of adequate power and weight to pull the machine.
Check that the machine is properly attached to the tractor. Be sure retainers are
used on the mounting pins.
Check the oil level in the gearbox. Add as required.
Check that the PTO driveline shield turns freely and that the driveline can
telescope easily. Clean and lubricate if required.
Check the blades. Be sure they are not damaged or broken and are bolted
securely to the rotor. Repair or replace as required.

65 Series Rotary Tiller
12
EQUIPMENT MATCHING
To insure the safe and reliable operation of the Tiller, it is necessary to use a tractor
with the correct specifications. Use the following list as a guide in selecting a tractor to
use on the machine.
1. Horsepower: Use Table 1 as a guide in selecting the tractor horsepower
appropriate for your width of machine. Use only small Agricultural tractors on this
machine.
Table 1 Horsepower vs. Width
Model Width Horsepower
50H 4.2 feet 40
(1.3m)
60H 5 feet 45
(1.5m)
72H 6 feet 55
(1.8m)
82H 7 feet 65
(2.1m)
ALERT: Do not exceed the recommended horsepower levels. The use of
horsepower will void the warranty.
2. Tractor Weight:
By following the recommendations for the tractor power, the tractor will have
sufficient weight to provide stability for the unit during field operation or when
transporting. It is also recommended that each tractor be equipped with a full
complement of suitcase weights on the front of the tractor. This will provide the
required weight on the front for turning and extra traction if equipped with front
wheel assist.
3. 3 Point Hitch:
The Tiller is equipped with a Category 1, 3-point hitch. Be sure the tractor 3-
point hitch is in the Category 1 configuration. Install the lift arm blocks or shorten
the stop chains to place the arms into the non-sway configuration. Refer to the
tractor manual for details.
4. Load Sensing Hydraulics:
Many newer tractors are equipped with “Load Sensing” hydraulics. It is the
responsibility of the operator to set the tractor hydraulic system to provide “float”
on the 3-point hitch. Refer to Tractor Manual for details. The float feature will
allow the machine to follow the ground contours during operation.
5. PTO Shaft:
The tractor must have a 1 3/8” 6 spline 540 rpm PTO shaft to fit the driveline
shaft supplied with the machine. Do not use shaft adapters or operate at any
other speed. It is not recommended that a tractor with variable speed PTO’s be
used on the Tiller. Operating at speeds faster than 540 rpm will overload the
drivetrain and lead to early failures.
Attach the safety chains supplied with the PTO shaft, allowing sufficient slack for
the driveline during turns and operation. Check booklet attached to the PTO for
instructions.
65 Series Rotary Tiller
13
DRIVELINE DIMENSION
A PTO driveline is supplied with the machine. To accommodate the variety of 3 point
hitch geometry available today, the driveline can be too long for some machines and
must be cut. It is very important that the driveline be free to telescope but not bottom
out when going through its working range. If the driveline bottoms out, the bearings on
both the machine and tractor PTO shaft will be overloaded and fail in a short time.
When cutting the driveline, follow this procedure:
1. Clear the area of bystanders, especially small children.
2. Attach the Tiller to the tractor but do not attach the driveline.
3. Raise the machine until the input shaft is level with the tractor PTO shaft.
4. Measure the dimension between the locking groove on the tractor PTO shaft and
the groove on the Tiller input shaft.
5. Measure the same dimensions on the compressed driveline.
6. If the driveline dimension exceeds the machine dimension, the driveline will have
to be cut.
65 Series Rotary Tiller
14
DRIVELINE DIMENSION – cont’d.
7. Pull the driveline apart and cut 1/2 of the dimension determined in step 5 from
each end. Add another ½ inch (12MM) to each cut off segment.
8. Be sure to use a hacksaw to cut 1/2 from each end of the separated shaft. Cut
both the plastic tube and the metal cores.
9. Use a file to remove the burrs from the edges that were cut.
10. Assemble the two ends of the shaft.
11. Make sure that the shaft can telescope freely. If it does not, separate the two
parts and inspect for burrs or cuttings on the shaft ends. Be sure it telescopes
freely before installing.
12. Make sure the plastic covering shield is free to rotate on the shaft before
installing on the machine.
65 Series Rotary Tiller
15
ATTACHING/UNHOOKING
The Tiller should always be located on a level, dry area that is free of debris and other
foreign objects. When attaching the machine to a tractor, follow this procedure:
1. Clear the area of bystanders, especially small children.
2. Be sure the tractor 3 point hitch is in the Category 1 configuration and the lift
arms are in the non-sway configuration (See tractor manual).
3. Make sure there is enough room and clearance to safely back up to the Tiller.
4. Attach the PTO driveline to the Tiller if it was removed for storage (See
Assembly).
5. While backing up, align the lift arm balls with the mounting pins on the Tiller.
ALERT: It may be necessary to add weight to the 3 point hitch to lower
the lift arms.
6. Stop tractor, set park brake, remove ignition key and wait for all moving parts to
stop before dismounting.
7. If your tractor is not equipped with a Quick Hitch:
a. Align the left lower link arm with the mounting pin.
b. Slide the ball over the pin and install the Linch Pin.
c. Use the screw jack on the right lift arm to align the ball with the pin.

FIELD OPERATION
Buhler Farm King 65 Series Rotary Tillers are designed with the inherent flexibility of
operating well in almost any kind of soil and terrain conditions. However, the operator
has the responsibility of being familiar with all operating and safety procedures and
following them.
Each operator should review this section of the manual at the start of the season and as
often as required to be familiar with the machine. When using, follow this procedure:
1. Review and follow the pre-operation Checklist. Review Safety Instructions.
2. Attach the tractor to the machine.
3. Before going to the field review Transporting Section.
4. Pull into the field and position the machine in a level area.
5. Lower into working position.
6. Set the machine:
a. Level the frame:
Use the screw jack on the right lift arm to level the frame from side-to-side.
b. Depth: Use the Depth Gauge Shoes on each side to set the operating
depth. Position the Depth Gauge Shoes in the top hole for shallow tilling
and in the bottom hole for deep tilling.
ALERT: In soft soil conditions, the skid plates become less effective and
sink into the ground. Use the turnbuckle on the top link to set the frame
angle so the bottom of the Depth Gauge Shoes are level when operating.
65 Series Rotary Tiller
18
FIELD OPERATION - cont'd.
c. Offset:
The Category Pin Brackets can be moved 3 to 4 inches along the Deck
Assembly to either side of center if required. Center the machine for
normal operation. Offset if the tire tracks are wider than the machine or
when tilling around trees, bushes or other areas.
ALERT: Sliding offset feature not available in the 82” model.
d. Drag Shield:
Adjust the chain in the Adjustment Bracket to set the height of the Drag
Shield. Set the Drag Shield to just contact the tilled soil when operating.
7. Align the unit with the working area.
8. Starting machine:
a. Run the engine at low idle.
b. Slowly engage the PTO control to start the machine.
c. Slowly bring the engine to the rated PTO speed. Never exceed rated
speed.
d. Lower the machine to the ground and proceed down the field.
9. Stopping machine:
a. Slowly decrease engine speed to low idle.
b. Raise machine out of the ground.
c. Disengage PTO clutch slowly.
CAUTION: Place all controls in neutral, lower machine, stop engine, set
park brake
remove ignition key and wait for all moving parts to stop before
dismounting.
10. Ground Speed:
Travel speed can vary between 2 and 5 mph (3 and 8 km/h) depending on the
soil and terrain conditions. It is the responsibility of the operator to note the
condition of the job being done and set the speed to obtain a quality tilling job
and maintain control of the machine. The speed can be increased to optimize
tilling. Decrease speed if you want the soil worked to a finer texture.
65 Series Rotary Tiller
19
FIELD OPERATION - cont'd.
11. Operating hints:
a. Determine the moisture content of the soil before starting. Soil that is too
wet will "ball-up" in the rotor blades making tilling impossible. Sandy soils
normally can be worked better than heavy clay or loam soils. It is the
responsibility of the operator to determine the soil type and moisture
content before starting. It may be necessary to wait for the soil to dry out
before starting to work.
b. Set the length of the Top Link to obtain the quality of the job desired
without needlessly using power and fuel in churning the soil. Use the
condition of the seedbed as your guide.
c. When tilling hard or compacted soils, it is recommended that two passes
be used when working. Use the Depth Gauge Shoes on each side of the
frame to adjust the tilling depth of the machine. The second pass should
be made at an angle to the first to give a consistent job and minimize
compaction.
d. Always remove heavy crop cover, all grass and weeds, before starting to
prevent rotor plugging.
e. The rotation of the Tines propel the machine in the forward direction.
Always use the tractor transmission to control the speed of forward travel.
f. Always disengage the PTO control and raise the machine out of the
ground before depressing the master clutch on the tractor.
g. Use low gear on the tractor to start the job. Increase the speed of forward
travel only as the quality of the job and power available will allow.
h. If the slip clutch slips, reduce the ground speed or raise the machine
slightly out of the ground.
65 Series Rotary Tiller

TRANSPORTING
When transporting the machine, review and follow these instructions:
1. Be sure all bystanders are clear of the machine.
2. Be sure that the machine is securely attached to the tractor and all retainer pins
are installed.
3. Clean the SMV emblem, lights and reflectors and be sure they are working.
4. Be sure you are in compliance with all applicable lighting and marking
regulations when transporting. Check with your local authorities.
5. Be sure your machine can clearly be seen by overtaking and oncoming traffic.
6. Keep to the right and yield the right-of-way to allow faster traffic to pass. Drive

8. Always use hazard flashers on the tractor when transporting unless prohibited by
law.
9. Use pilot vehicles front and rear when transporting during times of limited
visibility.
10. Never transport the machine faster than 20 mph (32 km/h). The ratio of the
tractor weight to the Tiller weight plays an important role in defining acceptable
travel speed. Table 2 summarizes the recommended travel speed to weight
ratio. Table 2 Speed vs. weight Ratio
Weight of fully equipped
or loaded implement(s)
relative to weight of

MAINTENANCE
By following a careful service and maintenance program for your machine, you will
enjoy many years of trouble-free operation.
A-FRAME ADJUSTMENT
When moving the hitch along the front frame to adjust the offset, follow this procedure:
1. Clear the area of bystanders, especially small children.
2. Raise the machine so it is slightly out of the ground.
3. Loosen the U-bolts through the Category Pin brackets.
4. Slide the hitch along the Deck until the machine is set at the desired
offset.
5. Tighten the U-bolts to their specified torque.
TINE REPLACEMENT
When the Tines are damaged in any way, they will need to be replaced. When
replacing, follow this procedure:
1. Clear the area of bystanders, especially small children.
2. Raise the machine until the Tines are slightly above the ground.
3. Stop engine, set park brake, remove ignition key and wait for all moving
parts to stop before dismounting.
4. Place blocks under each Depth Gauge Shoe to support the machine.
5. Raise the Drag Shield and secure in the up position.
6. Wear leather or heavy canvas gloves when handling Tines.
7. Remove mounting bolts from Tines.
ALERT: An alternate method would be to disconnect the machine from
the tractor and tip it forward on its nose.
8. Install a new replacement blade and tighten the mounting bolts to their
specified torque.
9. Lower the rear gate.
10. Remove the blocks under the skid plates.

SLIP CLUTCH
During normal operation, the slip clutch can release and slip when encountering an
obstruction or when overloaded. It is designed to slip when the load exceeds 3 times its
nominal rating. When the clutch slips too frequently during normal operating conditions,
it is necessary to replace the clutch linings. NOTE: The PTO shafts are shipped with
the slip clutch disengaged. There are four socket set screws on the inside of the clutch
assembly, which are turned out as far as they go to engage the clutch. Disengage
clutch by turning set screws in fully.
To replace clutch linings, follow this procedure:
1. Disengage the clutch by turning the four set screws all the way in.
2. Remove the outside bolts from the clutch assembly and replace the clutch
linings.
3. When re-tightening the bolts, stop when the clutch spacer starts to touch the
clutch plates. You should be able to just move the spacer by hand when you
have the correct bolt torque.
4. Engage clutch by turning out set screws after assembly is complete.
65 Series Rotary Tiller
27
CLUTCH MAINTENANCE
1. Before first use or after storage of more than one month, the clutch should be
checked.
2. Disengage clutch by turning in the four socket set screws.
3. Run the PTO at low idle to slip the clutch linings. This will help remove the dirt,
corrosion, and surface gloss from the clutch plates and also ensure that the
linings are loose.
4. Engage the clutch by turning out the socket set screws.
5. Normally the clutch will slip at a 20% higher torque after the “run in” than before.
6. Check the temperature of the clutch after running for 20 minutes and every 8
hours after that. If the clutch is hot to the touch or smokes, check that the
outside bolts are correctly tightened as explained in slip clutch section. If clutch
still slips, linings may have to be replaced.
