Ensure that all 4 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). 1. Jam nut 4.

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. 5 Connecting the Right-Hand Push Arm to the Cutting Unit Note: Immediately slide a 4 x 4 inch block of wood between the top of the push arm and the underside of the chassis. 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. No Parts Required Procedure Note: Position the capscrew heads and the flat washers to the outside of the castor arm. WARNING 4. Tighten the large jam nut securing the ball joint to the push arm.

combinations of weight required. Order parts from your local Authorized Toro Distributor. Product Overview Four Wheel Drive Groundsmaster 300 Series Traction Units do not need additional rear weight to comply with the ANSI B71.4-2012 and EN:5395:2013 Standards. Specifications Note: Specifications and design are subject to change without notice. Width of Cut 1.816 m (71–1/2 inches) 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 Operation 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. Note: Determine the left and right sides of the machine from the normal operating position.
Using the Grass Deflector DANGER 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. If the grass deflector is ever damaged, replace it immediately. Figure 14 1. Castor wheel 2. Tensioning cap • Never put your hands or feet under the mower. 4.
Selecting the Proper Height-of-Cut Setting to Suit Conditions Remove approximately 26 mm (1 inch) or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may have to raise the height-of-cut setting another notch. Mowing in Extreme Conditions Air is required to cut and recut grass clippings in the mower housing, so do not set the height-of-cut too low or totally surround the housing by uncut grass.
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.
Lubricating 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.

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.
