Setup Loose Parts Use the chart below to verify that all parts have been shipped. Procedure Description Use Qty. 1 2 3 4 5 Large castor wheel assembly Small castor wheel assembly 2 2 Install the castor wheel assemblies.
Note: Determine the left and right sides of the machine from the normal operating position. 1 Installing the Castor Wheel Assemblies 5 g021334 Parts needed for this procedure: 2 2 Figure 3 Large castor wheel assembly 1. Tensioning cap 3. Spacers Small castor wheel assembly 2. Thrust washers 4. Small (rear) castor spindle 3. Ensure that all four castor wheels are set at the same height-of-cut; then roll the cutting unit off of the wooden pallet.
3 Installing the Ball Joints and Connecting the Lift Cylinder No Parts Required Procedure Note: The ball joints are shipped with the traction unit. Figure 6 1. Thread the jam nut fully onto the right-hand ball joint (Figure 5). 2. Screw the ball joint into the right-hand push arm until the center of the ball joint is 60 mm (2-3/8 inches) away from the front of the push arm (Fig. 9). Do not tighten the jam nut. 1. Jam nut 4. Ball joint mount 2. 51 x 102 mm (2 x 4 inch) block of wood 3.

Have another person carefully push down on the push arm until the holes in the ball joint mount line up with the holes in the castor arm. Immediately slide a 4 x 4 inch block of wood between the top of the push arm and the underside of the chassis. Connecting the Right-Hand Push Arm to the Cutting Unit 5.
WARNING 6 Sudden release of the push arm could cause injury. Connecting the Left-Hand Push Arm to the Cutting Unit Make sure that the wooden block does not slip out. 3. Secure the ball joint mount to the castor arm with the capscrews, flat washers, and flange nuts previously removed. Position the capscrew heads and the flat washers to the outside of the castor arm. No Parts Required Procedure 4. Tighten the large jam nut securing the ball joint to the push arm.
2. Connect the ends of the tension spring between the fourth link of the rear chain and the eye of the cotter pin that holds the cylinder pin in place (Figure 12). Adjust the length of the chain so that the rear caster wheels are off of the ground in the transport position 9 Greasing the Machine No Parts Required Figure 11 Procedure 3. Roll pin and capscrews 1. Drive shaft yokes 2.
Product Overview Operation Specifications Note: Determine the left and right sides of the machine from the normal operating position. Note: Specifications and design are subject to change without notice. CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Width of 1.816 m (71–1/2 inches) Cut Height of Cut Adjustable from 25 to 102 mm (1 to 4 inches) in 13 mm (1/2 inch) increments Net Weight 226 kg.
Adjusting the Height-of-Cut The height of cut is adjustable from 25 to 102 mm (1 to 4 inches) in 13 mm (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.
Using the Grass Deflector dense grass you may have to raise the height-of-cut setting another notch. DANGER Mowing in Extreme Conditions Without the grass deflector mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blade(s) and thrown debris will cause injury or death. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Tighten the castor wheel nuts After the first 10 hours • Tighten the castor wheel nuts • Torque the blade bolts Before each use or daily • Lubricate the grease fittings • Check the blades Every 50 hours • • • • • Check the gear box lubricant Check the blade drive belt adjustment Clean under the cutting unit belt covers Tighten the castor wheel nuts Torque the blade bolts Ev
Lubrication Service Interval: Before each use or daily The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If the machine is operated under normal conditions, lubricate all bearings and bushings daily or immediately after every washing. The gear box must be lubricated after every 50 hours of operation.

Mounting the Cutting Unit to the Traction Unit 2. Remove the covers from the top of the cutting unit and set the covers aside. 3. Loosen idler pulleys to the release tension of the belts (Figure 24). 4. Remove the carriage bolts, lock washers and nuts holding the gear box in place. Lift the gear box off the mounting plate and lay it on top of the cutting unit (Figure 24). 1. Position the machine on a level surface and shut the engine off. 2.
2. Remove the tensioning cap and spacers from the top of the castor spindle. 3. Pull the castor spindle out of the mounting tube. Allow the thrust washer and spacer(s) to remain on the bottom of the spindle. 1 2 3 4. Insert a pin punch into the top or bottom of the mounting tube and drive the bushing out of the tube (Figure 25). Also drive the other bushing out of the tube. Clean the inside of the tubes to remove dirt. Figure 25 1. Castor arm tube 5 2. Bushings 4 2 1 G021327 Figure 26 5.
ignition key. Block the cutting unit to prevent it from accidentally falling. 1. Raise the cutting unit to the highest position, shut the engine off, and engage the parking brake. Block the cutting unit to prevent it from accidentally falling. 2. Grasp the end of the blade using a rag or thickly padded glove. Remove the special screw, belleville washer and blade from spindle assembly (Figure 27). 2.
shims in adjacent holes if more than one shim is added to any one hole location. 4. To check the blade for being straight and parallel, lay the blade on a level surface and check the ends. The ends of the blade must be slightly lower than the center, and the cutting edge must be lower than the heel of the blade. This blade will produce a good quality of cut and require minimal power from the engine.
Troubleshooting Problem The cutting unit will not cut or cuts poorly. Possible Cause Corrective Action 1. The blades are dull. 1. Sharpen the blades. 2. One or more blades are bent or damaged. 3. The blade screws are loose. 2. Replace the blades. 4. The cutting unit belts are loose or broken. 5. The gear box pulley is loose. 6. A gear box shaft is broken. 7. The PTO belt is broken. 8. The PTO pulley is loose or broken. 9. The PTO shaft is broken. 10.
