Heavy Duty Finishing Mower WARRANTY POLICY Buhler Manufacturing products are warranted for a period of twelve (12) months (90 days for commercial application) from original date of purchase, by original purchaser, to be free from defects in material and workmanship under correct, normal agricultural use and proper applications.
This creates powerful suction that lifts the grass for a crisp cut. A blade overlap prevents stripping and ensures the lawn is mowed evenly. Buhler Farm King Heavy Duty Finishing Mowers are built to be durable and long lasting. Each wheel yoke assembly includes a cutting height adjustment on the 1" wheel yoke shaft.
Remember, YOU are the key to safety. Good safety practices not only protect you, but also the people around you. Make these practices a working part of your safety program. Be certain that everyone operating this equipment is familiar with the recommended operating and maintenance procedures and follows all the safety precautions.
Read and understand the Operator’s Manual and all safety signs before operating, servicing, adjusting, repairing, or unplugging the equipment. Do not attempt any unauthorized modifications to your Buhler product as this could affect function or safety, and could affect the life of the equipment.
Review Transport Safety instructions in tractor manual before moving. Check with local authorities regarding transport on public roads. Obey all applicable laws and regulations.

HITCH ASSEMBLY INSTRUCTIONS The hitch is assembled except for the two pivot bars (#69). Bolt one end of each pivot bar between the welded brackets at the back of the deck using the bolts assembled in the mower. Remove the 3/4” bolt (#63) at the top of the hitch assembly. Using the same bolt, assemble with the pivot bars between the hitch weldment (#38) 1.
Park the unit on hard level ground with the mower slightly raised. 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 mower side to side. Adjust the turnbuckle on the top of the three-point hitch arms to level the mower front and back.
The Heavy Duty 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.
FIELD OPERATION The mower works best on dry grass. Slower cutting speed and occasional cleaning may be required on damp or wet grass. The PTO must run at the full 540 rpm for a good cut. Slower speeds or double cutting could be required for very high grass. Use a higher blade setting for rough areas to prevent scalping of the surface.
Heavy Duty Finishing Mower MAINTENANCE HEAVY DUTY FINISHING MOWER PTO SHAFTS MAINTENANCE: The cross journals and the shield bearings at both ends of the shaft should be greased every 8 hours. Use 1 or 2 pumps of high temperature grease. The cones on the outer PTO shield must be turned until the access holes line up with the grease nipple in the cross journals.
MOWER DECK WHEEL BEARINGS The mower wheel bearings are packed in grease when they are shipped. They should be repacked in fresh grease once a year or every 200 hours of usage. MOWER DECK WHEEL BEARINGS ITEM PART# DESCRIPTION 902422 Wheel Yoke 902489 1'' x 9 1/4'' long Wheel Yoke Pin...
Heavy Duty Finishing Mower MOWER GEARBOX LUBRICATION The gearbox should be filled with SAE90 oil to the bottom of the level plug when shipped. Check the mower gearbox before using and at regular intervals (approximately every 40 hours). See that the oil level is maintained. On the mower gearbox the vent plug also acts as the fill plug.
Heavy Duty Finishing Mower SPINDLE REPLACEMENT OUTER SPINDLES: remove the belt guard on the side required (#7 & #8). Loosen the belts by first loosening the bolts holding the gearbox base plate (#2). Turn the 5/8” hex nut (#3) on the threaded rod on the base plate until there is enough slack in the belt to slip it off the spindle pulley.

Heavy Duty Finishing Mower BLADE REPLACEMENT The mower deck must be securely blocked up or locked in place before doing a blade replacement. 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. Use heavy leather gloves to handle the blades.
A basic requirement for a steady top performance of the machine is proper and regular maintenance. Use only original BUHLER parts. Keep the machine in a functioning and efficient condition by completing the maintenance and lubrication work as listed in the maintenance checklist. If maintenance is due, no work is to be done with the machine.
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.

The mowers must be raised off the ground far enough to pull the wheel yoke (#5) out of the welded sleeves at the ends of the axles (#1). Be sure the tractor is turned off. Pull out the clip (#4) and remove the wheel yoke. There are ½” and 1” spacers to adjust the cutting height.
MOWER DECK BELT ADJUSTMENT Start by removing both belt guards on the mower deck. Loosen the bolts holding the gearbox base plate (#7).
