IMPORTANT SAFETY PRECAUTIONS This symbol is used to call attention to safety precautions that should be followed by the operator to avoid accidents. When you see this symbol, carefully read the message that follows and heed its advice. Failure to comply with safety precautions could result in serious bodily injury.
IMPORTANT FEDERAL LAWS AND REGULATIONS* CONCERNING EMPLOYERS, EMPLOYEES AND OPERATIONS. *(This section is intended to explain in broad terms the concept and effect of the following federal laws and regulations. It is not intended as a legal interpretation of the laws and should not be considered as such). U.S. Public Law 91-596 (The Williams-Steiger Occupational and Health Act of 1970) OSHA This Act Seeks: “...
SECTION I INTRODUCTION AND DESCRIPTION Figure 1-1 Wing Cylinder Center Gearbox Shield Height Adjustment Cylinder Hose Holder Rod Driveline Retainer Axle Axle Arm Pillow Block Shield U-Joint Tongue Clevis Laminated Tire Wing Transport Lock Tongue Height Adjustment Jackstand Replaceable Wing Skid Discharge Shield (Chains) Wing Gearbox free-swinging uplift blades designed for light mowing. Free-swinging blades reduce the shock of impact when a stationary object is hit.
Figure 2-5 D. If wing(s) are not level (parallel to center section, disconnect one end of the wing adjustment linkage (Figure 2-5) and adjust shorter to raise the wing outside edge and longer to lower the wing outside edge. It may be necessary to use wing lift cylinder to relieve pressure from the linkage retaining pin. E. Reconnect linkage.
IMPORTANT NEVER ADJUST THE LEVELING ROD SO THAT THE THREADED END OF ANY ROD IS NOT FULLY ENGAGED IN THE TURNBUCKLE. CAUTION FAILURE TO MATCH VALVE TO TRACTOR HYDRAULIC SYSTEM BY USING INCORRECT PLUG WILL CAUSE DAMAGE TO TRACTOR. A. Loosen jam nut on each linkage rod assembly (Figure 2-3). B. Rotate the rod to lengthen or shorten the leveling rod assemblies. Shortening the rods will raise the front of the cutter and lengthening rods will lower the front of the cutter.
Figure 2-5 D. If wing(s) are not level (parallel to center section, disconnect one end of the wing adjustment linkage (Figure 2-5) and adjust shorter to raise the wing outside edge and longer to lower the wing outside edge. It may be necessary to use wing lift cylinder to relieve pressure from the linkage retaining pin. E. Reconnect linkage.
F. Place tractor in gear and proceed forward. Advance tractor throttle to correct PTO speed for implement (540 RPM). Tractor forward speed should be controlled by gear selection, not engine speed. For maximum cutting efficiency, forward speed should allow cutter to maintain a constant, maximum blade speed. Failure to maintain proper blade RPM will result in poor cutting performance and excessive blade and blade bolt wear.
4-2 LUBRICATION (Figure 4-1) 7. Wing Turnbuckles - Apply multi-purpose grease slowly with grease gun. 8. Leveling Rod Links - Apply multi-purpose grease slowly with grease gun. 120 HOURS 9. Wheel Bearings - Apply multi-purpose grease slowly with grease gun until grease relieves around seal. NOTE The multi-purpose grease referenced in this section is an NLGI Grade 2 type grease. BEFORE EACH USE 1. Driveline Universal Joints - Apply 2-3 shots of multi-purpose grease with grease gun. 2.

4-3 BLADE REPLACEMENT 4-4 BLADE PAN REMOVAL It is not necessary to remove the complete blade holder assembly to replace the blades. Blade bolts are accessible through a hole in the top of the cutter deck. Always replace both blades on a spindle using two blades having the same weight. Use only genuine Bush Hog replacement blades. A. Remove nuts from blade bolts. A blade nut socket (Part No. 6432) can be bought at your Bush Hog dealer and used with an adjustable wrench (not supplied) to remove blade nut.
any spring that is unequal. Adjust all eight spring retaining nuts 1/3 of a turn (2 flats on a nut) and check clutch slippage. If further adjustment is necessary, do so in 1/3 turn increments. Adjust only to provide sufficient torque to prevent slippage under normal conditions. Occasional slippage is normal for drivetrain protection. If satisfactory results cannot be obtained consult your Bush Hog dealer.

Assemble wing axle assemblies to the wing decks by installing axle bushings 2-3/32” long, 3/4” x 3-1/2” bolts, flatwashers and locknuts.
FIGURE 5-6 Cylinder Lug Mounting Locations slips over the inner ring extension. Turn collar quickly in the direction of rotation (approximately 1/4 turn) to tighten. (Figure 5-9) O. Place punch in blind hole in collar. (Figure 510) Strike punch sharply with hammer in the direction of rotation to lock collar tightly against inner ring extension. Tighten set screw to 20 ft/lbs.
