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 1.52 m (60 inches) Cut Height of Cut Adjustable from 25 to 127 mm (1 to 5 inches) in 13 mm (1/2 inch) increments Net Weight 204 kg (450 lb.
Adjusting the Height-of-Cut 3. Remove the tensioning cap from the spindle shaft (Figure 6) and slide the spindle out of the castor arm. Put the 2 shims (1/8 inch) onto the spindle shaft as they were originally installed. These shims are required to achieve a level across the entire width of the cutting units. Slide the appropriate number of 1/2 inch spacers onto the spindle shaft to get the desired height-of-cut; then slide the washer onto the shaft.
Figure 11 1. Internal rollers Figure 9 Adjusting the Skids The skids should be mounted in the lower position when operating in height of cuts greater than 64 mm (2-1/2 inches) and in the higher position when operating in height of cuts lower than 64 mm (2-1/2 inches). Adjusting the Rollers Note: If the cutting unit is to be used in the 25 or 38 mm (1 or 1-1/2 inch) height-of-cut setting, the cutting unit rollers must be repositioned in the top bracket holes.

Rotate the cam lock to increase or decrease locking pressure This is the full open position. The suggested use for this position is as follows. 3. Position the baffle 4. Lock lever • • • • Positioning the Flow Baffle Use in tall, dense grass mowing conditions. Use in wet conditions. Lowers the engine power consumption.
Using the Side Discharge 6. Loosen the jam nuts on the bottom of the height-of-cut rods (Figure 17). The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. DANGER Without a grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.
Operating Tips Mow When Grass is Dry Mow either in the late morning to avoid the dew, which causes grass clumping, or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass. Select the Proper Height-of-Cut Setting to Suit Conditions Remove approximately 25 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 to the next setting.
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 castor arm bushings • Lubricate the castor wheel bearings • Check the blades Every 50 hours • • • • • • Check the gear box lubricant Lubricate the grease fittings Tighten the castor wheel nuts Torque the blade bolts Check th
Lubrication Service Interval: Every 50 hours 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 after every 50 hours of operation or immediately after every washing. 1.
Pre Maintenance Important: The fasteners on the covers of this machine are designed to remain on the cover after removal. Loosen all of the fasteners on each cover a few turns so that the cover is loose but still attached, then go back and loosen them until the cover comes free. This will prevent you from accidentally stripping the bolts free of the retainers. Separating the Cutting Unit from the Traction Unit Figure 24 1.
Servicing the Bushings in the Castor Arms holes in the castor arm bracket and the height of cut rod can be inserted into the lift arm pads (Figure 26). 5. Secure the lift arm to the castor arm with (2) thrust washers, a clevis pin and a hair pin cotter. Position the thrust washers between the lift arm and the castor arm bracket (Figure 26). Insert end of cotter pin into the slot in the castor arm tab to retain cotter pin.
Removing and Installing the Blade(s) 3. Check the bearings, spacer, and inside of the wheel hub for wear. Replace any damaged parts. 4. To assemble the castor wheel, push the bearing into the wheel hub. When installing the bearings, press on the outer race of the bearing. The blade must be replaced if a solid object is hit, the blade is out-of-balance, worn, or bent. Always use genuine Toro replacement blades to ensure safety and optimum performance.
Inspecting and Sharpening the Blade(s) Service Interval: Before each use or daily Every 50 hours DANGER A worn or damaged blade can break, and a piece of the blade could be thrown into the operator's or bystander's area, resulting in serious personal injury or death. Figure 31 • Inspect the blade periodically for wear or damage. 1. Cutting edge 3. Wear/slot forming 2. Curved area/sail 4. Crack WARNING • Do not try to straighten a blade that is bent.
Checking and Correcting Mismatch of Blades 2. Using a torque wrench or similar tool, move the idler pulley (Figure 33) away from the drive belt to release the belt tension and allow the belt to be slipped off the gearbox pulley (Figure 34). If there is mismatch between the blades, the grass will appear streaked when it is cut. This problem can be corrected by making sure that the blades are straight and all of the blades are cutting on the same plane. 1.
Replacing the Grass Deflector WARNING An uncovered discharge opening could allow the lawn mower to throw objects in the operator's or bystander's direction and result in serious injury. Also, contact with the blade could occur. • Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. • Make sure the grass deflector is in the down position. 1. Remove the locknut, bolt, spring and spacer holding the deflector to the pivot brackets (Figure 36).
