• • KEY OPERATION POINTS Cutting performance and distribution are best when cutter is level from side to side and front to rear. In extra heavy material, rear chains will allow better discharge and better distribution than solid rear bands. • • • • • • • Never operate the Flexwing below full PTO speed of 540 or 1000 rpm. For good distribution, the distribution baffles must be used. Deck rings may influence the quality of distribution.
SECTION II PREPARATION FOR USE 2-1 ATTACHING TO TRACTOR WARNING USE A PIECE OF CARDBOARD OR WOOD RATHER THAN HANDS AND WEAR EYE PROTECTION WHEN SEARCHING FOR HYDRAULIC LEAKS. ESCAPING HYDRAULIC OIL UNDER PRESSURE CAN PENETRATE SKIN. IF OIL IS INJECTED INTO SKIN, IT MUST BE SURGICALLY REMOVED WITHIN A FEW HOURS BY A DOCTOR OR GANGRENE MAY RESULT. A. IMPORTANT - Adjust tractor drawbar length to dimension shown in Figure 2-1.
C. Attach valve to top bracket using three 3/8” x 21/2” bolts, nuts and lockwashers. D. Mount top bracket to bottom bracket using quarter turn fasteners. Insert quarter turn fastener into clip-on receptacle and turn 90 degrees. 2-2 OPTIONAL VALVE MOUNTING BRACKET INSTALLATION (Figure 23) A. Place bottom bracket at desired mounting location. Mark 2-4 holes (as needed) for drilling using bracket as pattern. Drill holes using 13/32 drill bit. B.
If you are cutting in dense material, operating cutter with the rear slightly higher than the front will allow an increased volume of cut material to exit from underneath cutter. This will decrease the cutter horsepower requirements. CAUTION FAILURE TO MATCH VALVE TO TRACTOR HYDRAULIC SYSTEM BY USING INCORRECT PLUG WILL CAUSE DAMAGE TO TRACTOR.
Adjust the pitch as follows: A. Loosen jam nut on each linkage rod assembly. (Figure 2-3). B. Use the turnbuckles 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. While adjusting, alternate from one rod to the other. C. When the desired pitch is attained, make a final adjustment of the rods so that each will be under the same amount of tension.
A. Disengage tractor PTO. B. Raise cutter and install stop collars on height adjustment cylinder. Install transport lock. C. Raise wing(s) and insert transport lock pin(s). DANGER ROTARY CUTTER BLADES. STAND WELL CLEAR UNTIL ALL MOTION HAS STOPPED. TO AVOID AN ACCIDENTAL FALL FROM TRACTOR AND POSSIBLE INJURY OR DEATH BY MOWER, IT IS RECOMMENDED THAT TRACTOR BE EQUIPPED WITH ROLLOVER PROTECTIVE SYSTEM (ROPS) AND A SEAT BELT BE USED BY THE OPERATOR FOR ALL MOWING OPERATIONS. 3-3 OPERATION A.
include the components current safety decals specified by the manufacturer to be affixed to the component. 3. Store cutter in a dry place. WARNING THE CUTTER CAN FALL FROM HYDRAULIC SYSTEM FAILURE.

O. Install wing over center stops on each wing lug using 3/8 x 1” bolts and lock washers. Install wing lift cylinders with rod end connected to the wing lug. It may be necessary to remove port plugs to extend cylinder. Install the cylinder in the slotted holes. Place a 1-1/4” diameter x 1” long cylinder pin spacer bushing between the ears of the cylinder. Secure cylinder in slot with 53/8” pin, flatwashers and cotter pins.
AA. Fill each gearbox with six quarts (5.7L) of EP80W-90 gearbox oil. Allow time for oil to seep through bearings into lower housing. Replace temporary plugs with permanent plugs supplied in owner’s manual package. BB. On each clutch, loosen eight nuts retaining clutch springs 1/3 turn or until spring can be turned with fingers. CC. With tractor at idle speed, engage tractor PTO drive 2-3 seconds. Each clutch should slip without turning blades. DD. Retighten nuts to within 1/64” of original position.
