Use summer-grade diesel fuel (Number 2-D) at temperatures above -7°C (20°F) and winter-grade diesel fuel (Number 1-D or Number 1-D/2-D blend) below -7°C (20°F).
Checking the Tire Pressure Service Interval: Before each use or daily The correct air pressure in the tires is 138 kPa (20 psi). Important: Maintain the recommended pressure in all tires to ensure a good quality of cut and proper machine performance. Do not under-inflate the tires. Check the air pressure in all the tires before operating the machine. g033359 Figure 18 Rear Wheels WARNING Failing to maintain proper torque of the wheel-lug nuts could result in personal injury.
Lowering the Roll Bar Adjusting the Height of Cut Important: Lower the roll bar only when Important: The cutting units often cut necessary. approximately 6 mm (1/4 inch) lower than a reel cutting unit with the same bench setting. It may be necessary to set the cutting-unit bench measurement at 6 mm (1/4 inch) above that of reel cutting units cutting in the same area. Important: Ensure that the seat is secured with the seat latch.
7. Install the bolt finger-tight. 8. Repeat steps 4 through 7 for each side adjustment. 9. Torque all 3 bolts to 41 N∙m (30 ft-lb). Always tighten the front bolt first. Note: The InfoCenter displays "traction denied" and the machine should not move. If the machine does move, there is a malfunction in the interlock system. Correct this malfunction before operating the machine. Note: Adjustments of more than 3.
High-Lift, Parallel Sail The blade generally performs better in the higher heights of cut—7 to 10 cm (2 to 4 inches). Attributes: • It has more lift and a higher discharge velocity. • Sparse or limp turf is picked up significantly at higher heights of cut. • Wet or sticky clippings are discharged more efficiently, reducing congestion under the cutting units. • It requires more horsepower to run. • It tends to discharge further left and can tend to windrow at lower heights of cut.
Choosing Accessories Angle Sail Blade High-Lift, Parallel-Sail Blade (Do not use with the mulching baffle) Mulching Baffle Roller Scraper Grass Cutting—1.9 to 4.4 cm (3/4 to 1-3/4 inches) height of cut Recommended in most applications May work well in light or sparse turf Grass Cutting—5 to 6.
Slope Safety • Disengage the drive to the cutting unit and shut • • • • • • • off the engine before adjusting the height of cut (unless you can adjust it from the operating position). Never run an engine in an area where exhaust gases are enclosed. Never leave a running machine unattended. Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following: – Park the machine on a level surface.
Important: Do not run the starter motor accidentally. The brakes can also help you to maintain traction. For example, on some slopes, the uphill wheel can slip and lose traction. In this situation, press the uphill turn pedal gradually and intermittently until the uphill wheel stops slipping, thus increasing traction on the downhill wheel. more than 15 seconds at a time or premature starter failure may result.
Using Cruise Control The cruise-control switch locks in the pedal position to maintain the desired ground speed. Pressing the rear of the switch turns the cruise control off, the middle position of the switch enables the cruise-control function, and the front of the switch sets the desired ground speed. Note: Pressing either the brake pedal or moving the traction pedal into the REVERSE position, for 1 second, also disengages the pedal position.
Operating Tips Resolving After-Cut Appearance Operating the Machine Refer to the After-cut Appearance Troubleshooting Guide available at www.Toro.com. • Start the engine. If the AUTO IDLE function is Using Proper Mowing Techniques turned off, run it at HALF IDLE until it warms up.

Cooling System Maintenance Cooling System Safety • Swallowing engine coolant can cause poisoning; keep out of reach from children and pets. • Discharge of hot, pressurized coolant or touching a hot radiator and surrounding parts can cause severe burns. – Always allow the engine to cool at least 15 minutes before removing the radiator cap. – Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape. Checking the Cooling System g009702 Figure 71 1.
Cleaning the Cooling System Service Interval: Before each use or daily—Remove debris from the engine area, oil cooler, and radiator. Clean them more frequently in dirty conditions. This machine is equipped with a hydraulically driven fan drive system that automatically (or manually) reverses to reduce oil cooler/radiator and screen debris buildup. While this feature can help reduce the time required to clean oil cooler/radiator, it does not eliminate the need for routine cleaning.
Brake Maintenance Belt Maintenance Adjusting the Service Brakes Servicing the Alternator Belt Adjust the service brakes when there is more than 25 mm (1 inch) of free travel of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before you feel braking resistance. Service Interval: Every 100 hours 1. Release the locking latch from the brake pedals so that both pedals work independently of each other. 2.
Hydraulic System Maintenance High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46 Material Properties: Viscosity, ASTM D445 Hydraulic System Safety Viscosity Index ASTM D2270 Pour Point, ASTM D97 • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
Changing the Hydraulic Fluid Service Interval: Every 800 hours If the fluid becomes contaminated, contact your authorized Toro distributor, because the system must be flushed. Contaminated fluid looks milky or black when compared to clean oil. g198718 1. Park the machine on a level surface, engage the parking brake, lower the cutting units, shut off the engine, and remove the key. 2. Raise the hood. 3.

5. Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 82) and measure the heights. 6. Compare the 12 o’clock measured height to the height-of-cut setting. It should be within 0.7 mm (0.030 inch). The 3 and 9 o’clock heights should be 1.6 to 6.0 mm (0.060 to 0.240 inch) higher than the 12 o’clock setting and within 2.2 mm (0.090 inch) of each other. Note: If the 3 or 9 o’clock side is 1.6 to 6.0 mm (0.060 to 0.
Inspecting and Sharpening the Cutting-Unit Blade(s) Both the cutting edges and the sail, which is the turned-up portion opposite of the cutting edge, contribute to a good quality of cut. The sail lifts the grass up straight, thereby producing an even cut. However, the sail gradually wears down during operation, lowering the quality of cut even though the cutting edges are sharp. The cutting edge of the blade must be sharp so that the grass is cut rather than torn.
Storage Note: Remove the blades and sharpen them on a grinder. After sharpening the cutting edges, install the blade with the anti-scalp cup and blade bolt; refer to Removing and Installing the Cutting-Unit Blade(s) (page 65). Preparing for Seasonal Storage Traction Unit 1. Thoroughly clean the traction unit, cutting units, and the engine. 2. Check the tire pressure; refer to Checking the Tire Pressure (page 26). 3. Check all fasteners for looseness; tighten them as necessary. 4.
10. Check the anti freeze protection and add a 50/50 solution of water and ethylene glycol anti-freeze as needed for the expected minimum temperature in your area. Cutting-Unit Deck If the cutting-unit decks are separated from the traction unit for any length of time, install a spindle plug in the top of the spindles to protect the spindles from dust and water. g036712 Figure 87 1.
