greater the difference in reel speeds. Additionally, if the machine speed changes while you are cutting, the RDS system adjusts the reel speed to maintain a constant clip. This feature reduces turf thinning on the inside reel (in comparison to other riding greens mowers), which can reduce triplex ring. Mowing Reel Speed Options (cont'd.) 6 1550 7 1700 8 1850 9 2000 The RDS system also adjusts each wheel-motor speed during a turn, similar to the reel-motor speeds changing in a turn.

Inspecting and Cleaning after Mowing Hauling the Machine 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, bearings, and electronics. Do not wash the electrical connections with water. • Use a full-width ramp for loading the machine into • Use care when loading or unloading the machine into a trailer or a truck. a trailer or a truck.
Towing the Machine DANGER When the actuator is released from the brake, the machine is able to free wheel. A free-wheeling machine can cause serious injury to bystanders. Note: Refer to Figure 32 for this procedure. If the machine is not being towed, engage the parking brake. 8. Have an assistant sit in the seat, fasten the seatbelt, and use the brake while you tow the machine. Note: This ensures that the machine is under control when you tow the machine. 9. Remove the chocks from the tires. 10.
Maintaining the Lithium-Ion Batteries • When storing the machine for more than 10 days, ensure that the machine is in a cool and dry location, out of sunlight, rain, and wet conditions, and at least 50% charged. WARNING • If you are mowing in hot conditions or in sunlight, the battery may overheat. If this happens, a high-temperature alert will appear on the InfoCenter. In this condition, the cutting units are disengaged and the machine slows down.
Understanding the Lithium-Ion Battery Charger DANGER Contact with water while charging the machine could cause electric shock, causing injury or death. Refer to Figure 34 for an overview of the battery-charger displays and cords. • Do not handle the plug or the charger with wet hands or while standing in water. • Do not charge the batteries in the rain or in wet conditions. Important: Check the power supply cord periodically for holes or cracks in the insulation. Do not use a damaged cord.
Recommended Temperature Range for Charging 9. Observe the charger to ensure that the batteries are charging. Charging range 0° to 45°C (32° to 113°F) Note: The battery-charging indicator light Low-temperature charging range (Reduced Current) -5° to 0°C (23° to 32°F) should be flashing and the charging-output indicator light should illuminate. High-temperature charging range (Reduced Current) 45° to 60°C (113° to 140°F) 10.

Servicing the Batteries Note: The machine is equipped with 8 lithium-ion batteries. A lithium-ion battery must be disposed of or recycled in accordance with local and federal regulations. If a battery requires service, contact your authorized Toro distributor for assistance. The only user serviceable parts on a battery are the labels. If you attempt to open the main compartment of a battery, you will void your warranty.
Changing the Traction-Motor-Gearbox Fluid Drive System Maintenance Checking the Tire Pressure Service Interval: After the first 8 hours Every 800 hours Service Interval: Before each use or daily Fluid specification: SAE 80W90 Vary the tire pressure for all 3 wheels, depending upon your turf conditions, from a minimum of 83 to a maximum of 110 kPa (12 psi to 16 psi). Gearbox oil capacity: approximately 384 ml (13 fl oz) 1. Important: Ensure that the tire pressure for each wheel is identical.

Brake Maintenance Cutting Unit Maintenance Adjusting the Brakes Blade Safety If the brake fails to hold the machine while parked, you can adjust the brakes; contact your authorized Toro distributor or refer to the Service Manual for more information. A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death. • Inspect the blades and bedknives periodically for excessive wear or damage.
Installing the Cutting Units 4. The suspension needs to be lowered in order to install the cutting units. Perform the following steps to lower the suspension: 1. Park the machine on a clean, level surface. 2. Set the function-control switch to the NEUTRAL position. 3. Insert the key into the switch and turn it to the ON position. 4. Lower the suspension using the lift/lower joystick. 5. Engage the parking brake, shut off the machine, and remove the key.
CAUTION If you do not disconnect the power to the machine, someone could accidentally start the cutting units, causing serious injury to hands and feet. Always separate the disconnect the main-power connectors before working on the cutting units. 4. Push the motor retaining bar out of the slots on the motor toward the cutting unit and remove the motor from the cutting unit. g036122 Figure 56 g036123 1. Reel motor 3. Cavity 2. Spline shaft 4.

Important: Do not raise the suspension to the transport position when the reel motors are in the holders in the machine frame. Damage to the motors or wires could result. If you must move the traction unit without the cutting units installed, secure them to the suspension arms using cable ties. 6. Open the latches on the suspension-arm bar of the cutting unit you are removing (Figure 54). 7. Disconnect the latches from the cutting-unit bar. 8. Roll the cutting unit out from under the suspension arm.
