SET-UP INSTRUCTIONS DANGER 1 Do not start the engine and engage the PTO lever when PTO shaft is not connected to cut ting unit gear box because the PTO shaft will rotate with enough force to cause serious in jury. INSTALL CASTOR WHEEL ASSEMBLIES (Fig. 1 & 2) 3 2 4 2 The thrust washers, spacers and tensioning caps have been installed on the castor wheel spindles for shipping. 1. Remove tensioning caps from spindle shafts and slide off spacers and thrust washers. 1 3 1. Tensioning cap 2.
SET-UP INSTRUCTIONS CONNECT LIFT ARMS TO CUTTING UNIT (Fig. 4-5) 1. Move cutting unit into position in front of traction unit. 2. Measure distance from end of each lift arm to center of ball joint (grease fitting). Distance should be 2.25". If distance is not 2.25", loosen jam nut securing ball joint to lift arm and rotate ball joint in or out until distance is attained. Do not tighten jam nuts at this time. 1 3 5. Tighten large jam nut securing ball joint to lift arm (FIg. 5).
SET-UP INSTRUCTIONS 6. Mount bottom of knee link to deck bracket with a shoulder bolt and locknut. Use the heavy rate extension on the left hand side (large diameter spring wire) and the light rate extension spring on the right, discharge side (small diameter spring wire). 3 2 1 4 3 7. Align slotted holes in the spring cover (slot toward the bottom) with the mounting bracket holes. Insert lock pin assemblies into the bracket holes and secure each to the bracket with self-tapping screws (Fig. 9).
SET-UP INSTRUCTIONS 8. From the bottom, insert the spring and top spring end into the spring cover. Select a hole that matches the cutter deck height-of-cut setting; i.e., top cover hole matches the highest height setting, bottom cover hole the lowest, etc. Align the top spring end hole with the selected spring cover holes and insert the clevis pin to secure the spring inside the cover (Fig. 9). Secure clevis pin with a hair pin cotter. 1 2 9. Remove the blocks from under the cutting unit.
BEFORE OPERATING ADJUSTING HEIGHT-OF-CUT (Fig. 12-13) The height-of-cut is adjustable from 1 to 4 inches in 1/2 inch increments, by adding or removing an equal number of spacers from the front and rear castor forks. The height-of-cut chart below gives the combinations of spacers to use for all height-of-cut settings.

BEFORE OPERATING 1 1 2 Figure 16 Figure 14 1. Internal rollers 1. External Roller 2. Roller Shaft CHECK LUBRICANT IN GEAR BOX (Fig. NO TAG) To adjust front gage wheel (Fig. 15): 1. Remove capscrew and nut securing gage wheel to cutting unit brackets. 2. Align roller and spacer with top holes in brackets and secure with capscrew and nut. The gear box in designed to operate on SAE 80-90 wt. gear lube.
OPERATING INSTRUCTIONS GRASS DEFLECTOR (Fig. 18) TENSION SPRING ADJUSTMENT WARNING The grass deflector (Fig. 18) is a safety device that diverts grass and other foreign objects being discharged downward. WE STRONGLY RECOMMEND THAT THE DEFLECTOR BE IN ITS NORMAL OPERATING POSITION WHENEVER THE CUTTING UNIT IS ENGAGED. NEVER OPERATE CUTTING UNIT WITH THE DEFLECTOR REMOVED FROM THE CUTTING UNIT OR IT TIED/BLOCKED IN A RAISED POSITION.
LUBRICATION GREASE BEARINGS, BUSHINGS AND GEAR BOX (Fig. 19-22) The cutting unit must be lubricated regularly. If machine is operated under normal conditions, lubricate castor bearings and bushings with No. 2 general purpose lithium base grease or molybdenum base grease, after every 8 hours of operation or daily, whichever comes first 1. The cutting unit has bearings and bushings that must be lubricated, and these lubrication points are: front castor spindle bushings (Fig.

MAINTENANCE SEPARATING CUTTING UNIT FROM TRACTION UNIT (Fig. 23-25) 5. Roll cutting unit away from the traction unit separating male and female sections of PTO shaft. 1. Position machine on a level surface, raise cutting unit, engage parking brake, be sure traction pedal is in neutral position, PTO lever in OFF position, shut engine OFF and remove key from switch. CAUTION Counterbalance spring(s) are in tension when deck is in lowered position. Always raise deck before adjusting or removing spring(s). 2.
MAINTENANCE SERVICING CASTOR ARM BUSHINGS (Fig. 26) The castor arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move castor fork back and forth and from side to side. If castor spindle is loose inside the bushings, bushings are worn and must be replaced. 1. Raise cutting unit so wheels are off floor and block it so it cannot fall accidentally. 2.
MAINTENANCE CHECKING FOR BENT BLADE (Fig. 28) 1. Position machine on a level surface, raise cutting unit, engage parking brake, be sure traction pedal is in neutral position, PTO lever in OFF position, shut engine OFF, remove key from switch and disconnect wires from spark plugs. Block cutting unit to prevent it from falling accidentally. 3 2. Rotate blade until the ends face forward and backward. Measure from inside of cutting unit to cutting edge at front of blade (Fig. 28), and remember this dimension.
MAINTENANCE CORRECTING CUTTING UNIT MISMATCH (Fig. 32-33) If one cutter blade cuts lower than the others, correct as follows: A 1. Lower cutting unit onto a level surface, engage parking brake, be sure traction pedal is in neutral position, PTO lever in OFF position, shut engine OFF, remove key from switch and disconnect wires from spark plugs. Make sure tire pressure is equal on all tires. B 2. Raise height-of-cut to the 4 in. position: refer to Adjusting Height-Of-Cut. C 3.
MAINTENANCE 8. Compare measurements at various positions. All dimensions must be equal within 1/4 in. from any two adjacent blades. The difference between dimensions of all three blades must not exceed 3/8 in. If difference exceeds specifications proceed to step 9. 9. Remove capscrews, flatwashers and locknuts from outer spindle in the area where shims must be added. To raise or lower the blade, add a shim, Part No. 3256-24, between spindle housing and bottom of cutting unit.
MAINTENANCE 2. Release and unhook latches securing covers to top of cutting unit. Remove covers. 2 1 3. Loosen two nuts securing idler plate in place and remove old belt from pulleys. 4. To install new belt, the gear box base must be removed. To do this, remove four carriage bolts and locknuts holding gear box base. 5. Install new belt around gear box pulley, spindle pulleys, stationary idler pulley and adjustable idler pulley. 3 6. Install gear box base with carriage bolts and locknuts. 7.
