Select the height-of-cut at which the cutting units are set. 2. Choose the desired ground speed best suited for conditions. 3. Using the appropriate graph (Figure 19) for 5-, 8-, 11-, or 14-blade cutting units, determine the proper reel speed setting. For a list of faults, refer to your Authorized Toro Distributor or the Service Manual.
Fuel-Shutoff Valve Cutting Unit Power Disconnect Connectors Close the fuel-shutoff valve (Figure 22), behind the seat and under the fuel tank, when storing or transporting the machine on a truck or trailer. Before installing, removing, or working on the cutting units, disconnect the cutting units from the power supply by separating the cutting unit power disconnect connectors (Figure 23), located at the base of the rollover bar on the left side of the traction unit.
Attachments/Accessories Operation A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Exmark.com for a list of all approved attachments and accessories. Note: Determine the left and right sides of the machine from the normal operating position.
Filling the Fuel Tank Fuel Specification 1. Fuel tank capacity: 26.6 L (7 US gallons) Clean around the fuel-tank cap and remove it (Figure 24 or Figure 25). Recommended Fuel: Unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method) Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
During Operation Important: Do not fill the fuel tank completely full. 3. Install the cap. During Operation Safety Note: You will hear a click sound when the cap is secure. 4. General Safety Wipe up any spilled fuel. • The owner/operator can prevent and is responsible Performing Daily Maintenance • Service Interval: Before each use or daily Before starting the machine each day, perform the following procedures: • • Check the engine-oil level—refer to Checking the • Engine Oil (page 36).
– Park the machine on level ground. – Disengage the power take-off and lower the attachments. – Engage the parking brake. – Shut off the engine and remove the key. – Wait for all moving parts to stop. – Rollover Protection System (ROPS) Safety – • Do not remove the ROPS from the machine. • Ensure that the seat belt is attached and that you • • • • – can release it quickly in an emergency. Always wear your seat belt. Check carefully for overhead obstructions and do not contact them.
Checking the Safety-Interlock System the choke by pulling it rearward to the OFF position. A warm engine requires little or no choking. Service Interval: Before each use or daily Checking the Machine after Starting the Engine 1. Move the throttle lever to the FAST position. 2. Move the raise/lower mow control lever forward momentarily. CAUTION If the safety interlock switches are disconnected or damaged the machine could operate unexpectedly, causing personal injury.
2. 3. 4. Move the functional-control lever to the MOW position or the TRANSPORT position and try to start the engine. Driving the Machine without Mowing The engine should not turnover or start, which indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly. • Ensure that the cutting units are fully raised. • Move the functional-control lever to the TRANSPORT position.
gaining the required timing necessary to minimize the cleanup mowing operation. Note: The delay in raising and lowering the center cutting unit depends on hydraulic fluid temperature. Cold hydraulic fluid results in a longer delay. As the fluid temperature increases, the delay time becomes shorter. 4. Overlap a minimal amount with the previous cut on return passes.
Cutting the Periphery and Finishing the Job 1. After Operation Finish cutting the green by mowing the outer periphery. Change the direction of cutting from the previous mowing. After Operation Safety General Safety Note: Use the throttle lever to adjust the machine speed when you cut the periphery. This will match the clip to the green and may reduce triplex ring.
Towing the Machine Inspecting and Cleaning after Mowing In case of an emergency, you can tow the machine for up to 0.4 km (1/4 mile). After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals and bearings. Do not wash a warm engine or the electrical connections with water. Important: Do not tow the machine faster than 3 to 5 km/h (2 to 3 mph) to avoid damaging the drive system.
Maintenance CAUTION Failure to properly maintain the machine could result in premature failure of machine systems causing possible harm to you or bystanders. Keep the machine well maintained and in good working order as indicated in these instructions. Note: Determine the left and right sides of the machine from the normal operating position. Note: Download a free copy of the electrical or hydraulic schematic by visiting www.Exmark.com and searching for your machine from the Manuals link on the home page.
