INTRODUCTION
The Buhler Farm King Series 1 Rotary cutter available in 48” and 60” and is equipped
with a 3-point hitch. The 3-point hitch is Buhler Quick Hitch compatible so it is easy to
attach and unhook. 3-point hitch models include a single solid rubber training wheel.
Buhler Farm King Rotary Cutters are built tough and made to last. The blades are heattreated to enhance rigidity and the heavy-duty gearbox is designed to be rugged and
durable. The access panel on the deck makes it easy to inspect or replace the blades.
An optional chain kit minimizes the possibility of flying debris.
Keep this manual handy for frequent reference. All new operators or owners must
review the manual before using the equipment and at least annually thereafter. Contact
your Buhler Dealer if you need assistance, information, or additional copies of the
manual. Visit our website at www.buhler.com for a complete list of dealers in your area.

ASSEMBLY INSTRUCTIONS
1. Raise the hitch arms (#4) and the hitch supports (#5) from the deck. Remove the
bolt holding on the top link (#6). Line up the end holes on the hitch supports with
the holes on the outside of the hitch arms where you just removed the bolt. Bolt
the hitch arms, hitch supports and top link together with the bolt you just removed
using two flat washers and a lock nut.
2. Connect the PTO shaft to the gearbox. A snap ring holds on the PTO shaft with
a shear pin. Make sure the PTO guard (#3) is bolted in place.
3. Re-check all the fasteners. There should be free movement of all pieces held
together by a bolt and lock nut.
CHAIN KIT - ASSEMBLY INSTRUCTIONS
All cutters have the required holes for mounting the chain kit. The use of this chain kit
will help reduce the possibility of injury to persons or property by stopping many thrown
objects.
1.
Bolt the front chain holder (#1) to the front of the cutter using 3/8” x 1" hex bolts,
lock washers, flat washers and hex nuts.
2.
Use ¼” x 5 link chains (#8) at the front. A chain is pushed through each slot from
underneath and a 3/8" rod is threaded through the top link of each chain. Hold
rods in place using the cotter pins supplied. See parts list for correct length of
rods.
3.
Bolt the rear center (#3) and rear side (#4 & #5) chain holders to the rear of the
cutter. Use ¼” x 5 link chains (#8) along all rear edges. Thread rods as in front
using lengths as shown in parts list.

Series 1 Rotary Cutter
OPERATING INSTRUCTIONS
1.
Connecting to tractor: All cutters are supplied with a standard 1 3/8" 6-spline
yoke on the PTO shaft.
Warning: This cutter is designed to operate only with a 540 rpm PTO. After
connecting cutter to tractor and before doing any cutting, check to see that the
PTO shaft is not touching anywhere on the cutter when raising and lowering or
when cornering.
2.
PTO Shafts: Make sure the length of the PTO shaft is compatible with different
working positions of the cutter. Carefully follow the lubrication chart supplied with
the PTO shaft. When cutting, avoid joint angles over 35º. PTO shafts should be
disengaged when turning sharp corners. Using tape or a bright colored marking
pen, mark on the outer shields the position where the shaft is completely pushed
together and the position where you have a 4" overlap. Watch these marks when
moving the cutter through all possible operating angles to see that the PTO shaft
stays within this range.
PTO shafts with shear pin - Loosen the outer shield on the implement end of the
PTO and push the gearbox shaft through the end yoke. Using snap ring pliers,
put the snap ring on the end of the gearbox shaft. This is what keeps the PTO
shaft on if the shear pin breaks and the cutter should not be used without it.
Insert a ½” x 3 ½” Grade 2 bolt with a lock nut to act as shear pin and replace all
shields.
3.
Operating tractor engine: Operate the tractor PTO at 540 rpm when doing
normal cutting. If the forward speed is too high, a lower gear can be used.
4.
Cutting: The cutter should be run with the front end a little low or just level for
normal light cutting. For brush or dense tall weeds, running front end high may
give a better shredding job. On rough ground, the front end will also tend to dig
in less. The cutter can also be used to shred stubble or top vegetables prior
to harvest.

THEORY OF OPERATIONS

Series 1 Rotary Cutter
MAINTENANCE
SERVICING INSTRUCTIONS
LUBRICATION
1.
Gearbox: The gearbox should be filled with SAE90 oil to the bottom edge of the
lower oil plug when shipped. Check this before using the cutter and at regular
intervals to see that this oil level is maintained.
2.
Grease wheels, tail wheel spindle sleeve, universal joints and shield bushings on
the PTO shaft after every eight hours of use. Lubricate the telescoping PTO tube
and the PTO quick release about every twenty
hours of use.
3.
Shielding: Always keep all shielding in place and repair or replace if damaged.
4.
Blades: When replacing or grinding the cutting blades, both blades must be
replaced or reground at the same time to maintain the proper balance in the
cutting unit.
IMPORTANT: Use Buhler replacement blades only. Using substitute blades
may be dangerous. When changing blades, open the access door on the deck
and take the screws out of the blades. Replacing the new or sharpened blades
is done with the back of the mower raised and securely blocked so it will not fall.
Bolt on the blades and close the access door.
