Finishing Mower

INTRODUCTION

Buhler Farm King has been building top quality finishing mowers for 15 years and has
refined these mowers to be among the best in the industry. Manufactured with top
quality material, the edge of the mower deck features solid reinforcing rods. These
finishing mowers are Buhler Quick Hitch compatible and are available in widths ranging
from 48" to 84".
Each mower features three high-speed blades with one of the highest rated tip-speeds
in the industry. This creates powerful suction that lifts the grass for a crisp cut. A blade
overlap of 1 5/8" to 2 5/8" prevents stripping and ensures the lawn is mowed evenly.
Buhler Farm King Finishing Mowers are built to be durable and long lasting. Pneumatic
tires with puncture proof sealant are standard. Each wheel yoke assembly includes a
cutting height adjustment on the 1" wheel yoke shaft. Bushings in the wheel hubs
ensure long-term reliability without needing frequent lubrication. A slide adjustment is
located under the gearbox for easy belt tensioning.

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.
The directions left, right, front and rear, as mentioned throughout this manual, are as
seen facing in the direction of travel of the implement.

OPERATING INSTRUCTIONS

The Finishing Mower is designed to be used on a tractor with a standard category 1
three-point hitch. See the specification sheet for horsepower requirements. Using
excessive power will shorten the life of the drive train components.

CONNECTING TO TRACTOR:

Park the mower and tractor on a level dry area free of debris and foreign objects.

1. Slowly back the tractor up to the machine.

2. Adjust the three-point arms to align with the mower lift pins.

3. Stop the tractor, set the parking brake and remove the ignition key before
dismounting.

4. Slide the three-point arms on the lift pins and lock in place with the clips

supplied.

5. With the tractor engine shut off, attach the PTO shaft. Both ends of the
PTO have a standard 6-spline end with a spring-loaded locking collar.
Turn the round collar at the ends of the PTO clockwise to slide onto the
splined shafts. The spring-loaded pin in the PTO yoke must lock into the
groove on the splined shaft on the gearbox and tractor. Always check to
see that both ends of the PTO shaft are securely attached every time the
mower is used. This should always be done with the tractor engine shut
off. 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.
NOTE: At lease one third of the telescoping length of the PTO
should overlap when the mower is in operation.

6. Attach the top link on the tractor to the link pin assembled in the hitch
weldment (#45). Adjust the turnbuckle on the tractor top link so that the
upper lift bracket hangs straight down with the tractor and mower both on
level ground.

10

Finishing Mower

FIELD USE PREPARATION

Read and understand the Operator’s Manual and all safety signs before operating.
The implement and tractor should be on a dry level area, clear of debris.
Lower the three point arms on the tractor so they line up with the mounting pins on the
implement.
Stop the engine and set the brake.
Mount the lower lift pins first and then adjust the implement angle using the turnbuckle
on the top link. Check that all the clips holding the three point pins are securely in place.
Start the engine, and raise the implement slightly.
Adjust the sway blocks or chains on the tractor so the mower is centered between the
rear wheels.
Adjust the three-point hitch arms to level the implement from side to side.
Adjust the turnbuckle on the top of the three-point hitch arms to level the implement
from front to back.
Adjust the cutting height using the wheel spacers on the wheel yokes. The spacers
should be set at the same height on all four wheels.
Check for proper air pressure in tires.
Check tightness of belts, bolts, and other hardware.
Check blades to see if they are damaged. Sharpen or replace blades if necessary.
Check that blade bolts are tight.
Clear the working area of foreign objects and check that all bystanders are standing
clear before starting.
Start the tractor with the mower resting on the ground on all four wheels.
Slowly engage the PTO and bring the speed up to 540 PTO rpm for cutting.

FIELD OPERATION

1. The mower works best on dry grass. Slower cutting speed and occasional
cleaning may be required on damp or wet grass.

2. The PTO must run at the full 540 PTO rpm for a good cut.

Slower speeds or double cutting could be required for very high grass.

3. Use a higher blade setting for rough areas to prevent scalping of the
surface.

4. Always cut counter-clockwise so grass clippings are thrown on the grass
already cut. This saves power and wear on the blades.

5. Sharpen blades if grass tears instead of cutting cleanly.

6. Slow down when cutting corners. Turning too sharply on corners can
leave a small strip of grass uncut.

11

Finishing Mower

DISCONNECTING FROM TRACTOR

1. Park on a firm level area and clean the mower.

2. Lower the mower until the load is off the hitch arms.

3. Disconnect the hitch arms and the PTO shaft.

4. Cover the mower for storage to prevent rust.

REAR DISCHARGE MOWER CHAIN KIT ASSEMBLY

1. With the narrow lip of the chain guard plate (#2) turned up, push an end link of a
3-link chain up through the slot nearest the end of the guard plate. The chain rod
(#3) slides through the chain link along the top surface of the chain guard plate.
Slide through each chain in order along the entire guard plate. Slide a flat washer
on each end of the rod. Hold the assembly in place with a 1/8” x 1” cotter pin
(#8) at both ends of the rod.

2. A 5/8” long spacer (#6) fits between the guard plate and the rear lip on the deck.
These spacers must be centered on the holes in the guard plate and the rear lip
on the deck. With the spacers in place, position the chain guard assembly under
the lip on the deck. Clamp on assembly to hold in place. Bolt guard plate
assembly to the deck using 3/8” x 1 1/2” bolts, lock washers and hex nut.

QUICK HITCH KIT INSTRUCTIONS

SIDE & REAR DISCHARGE FINISHING MOWER

1. Remove the two sets of lift brackets with the lower lift pins from the mower

hitch arms (#4).

2. Bolt the adaptor plates (#13) to the outside of the hitch arms welded to the

deck. Turn the plates as shown in drawing. Use the 3/4” x 2 1/2” bolts and
bushings in the 1” holes. The 5/8” x 2” bolts holding on the a-frame weldment
are removed and replaced with 2 1/2” bolts (#3) which also fit through the
adaptor plates. The bushings already in the A-frame must remain in place.

3. Assemble the two quick hitch arms (#4) on the inside of the adaptor plates

using the lift pins with the swivel bushings from step one at the bottom. The
A-frame and the quick hitch arms are connected at the top using an adaptor
weldment (#11). With the welded bushings on the adaptor facing down, the
A-frame is attached using the top link pin (#9). The hitch arms (#4) are bolted
on using a 3/4” x 4 1/2” bolt (#1) which fits through a 2 3/8” spacer (#12).

MAINTENANCE

1. GEARBOX: The gearbox should be filled with SAE 90 oil to the bottom of
level plug when shipped. Check the mower before using and at regular
intervals (approx. every 40 hours). See that this oil level is maintained.

2. GREASE: Grease wheel yokes, wheel bushing and PTO u-joints
approximately every 8 hours. Before using the mower for the first time,
grease wheel bushings until you can see the grease squeezed out at the
ends of the wheel hub. Lubricate the telescoping PTO tube and the quick
release collars on the ends of the shaft about every 20 hours. Clean all
grease fittings before injecting grease and immediately replace any
damaged or missing grease fittings. When using the safety chains
supplied with the PTO shaft, the shield bearings must be kept lubricated.
NOTE: There is no grease nipple on the spindles because they use
sealed bearings.

3. SHIELDING: Always keep all shielding in place and repair or replace if
damaged.

4. BLADES: When replacing or grinding blades, all three blades must be
replaced or reground at the same time to maintain the proper balance in
the cutting unit. Block up the mower securely before attempting to remove
the blades. Use heavy leather gloves to handle the blades. Be sure to
tighten center bolt and lock washer securely when replacing blades. Use
a torque wrench to re-tighten spindle bolts to 180 ft.-lbs. (244 N-m). The
bolts have a patch of thread lock material pre-approved which will hold for
up to five usages. Always replace the lock washer with the extra heavy
duty washer supplied with the spindle

MAINTENANCE – Cont’d.

5. BELTS: Remove the belt guards to check belt tightness. The center of
the belt span should deflect about 1/2” with nominal pressure. If the belts
slip or are too loose, the bolts holding the gearbox must be loosened. Use
the threaded tightener rod on the gearbox mount to tighten the belts. Lock
the rod in place and re-tighten the gearbox bolts when the belts are
properly tightened. Replace belt guards. Changing belts follows the same
procedure as given in the preceding paragraph, except you will have to
loosen the belts further to remove them. The belt installation is shown in
the following drawing. NOTE: Belts should always be replaced in
matched sets.

7. TIRES: Maintain proper air pressure in tires.
50 psi (345 kPa) max. for 4’, 5’, & 6’ Finishing Mowers
40 psi (276 kPa) max. for 7’ Finishing Mowers

16

Finishing Mower

BOLT TORQUE

CHECKING BOLT TORQUE

The tables shown below give correct torque values for various bolts and hex bolts.
Tighten all bolts to the torques specified in chart unless otherwise noted. Check
tightness of bolts periodically, using bolt torque chart as a guide. Replace hardware
with the same strength bolt.

NOTE: See page 15 for correct spindle torque. Do not use this chart for spindle

bolt only.

Torque figures indicated above are valid for non-greased or non-oiled threads and
heads unless otherwise specified. Therefore, do not grease or oil bolts or hex bolts
unless otherwise specified in this manual. When using locking elements, increase
torque values by 5%.

* Torque value for bolts and hex bolts are identified by their head markings.
