Service braking is achieved by the hydraulic transmission system. When the forward or reverse traction pedals are released or the engine speed is reduced, service braking becomes effective and travel speed is automatically reduced. To increase the braking effect, push the traction pedal into the NEUTRAL position. Service braking is effective on the front wheels only.

In the event of service brake failure, turn the ignition off to bring the machine to a standstill.

Forward travel: Press the forward traction pedal to increase forward travel speed. Release the pedal to reduce speed (Figure 16).

Reverse travel: Press the reverse traction pedal to increase reverse travel speed. Release the pedal to reduce speed (Figure 16).

Stop (Neutral): To stop the machine, use 1 of the following procedures:

• Reduce your foot pressure on the traction pedal and allow it to return to the neutral position. The machine dynamically brakes to a smooth stop.

• Tap or hold the reverse pedal briefly. This stops the machine faster than dynamic braking.

It is important to keep the flail blades sharp and in good condition to ensure good cutting performance, minimum power consumption, and a good quality of cut.

The flail head is a fine cut flail and should only be used for maintaining grass. Its recommended that a maximum of 1/3 of the total grass length is removed when cut.

The scraper wires are fitted to remove debris from the roller, in dry conditions these may not be required and its recommended they are removed. In damp wet conditions ensure that scraper wires do not get plugged with debris.

The cutting unit floats and can pivot laterally to follow ground contours.

The cutting units are designed to be operated at full engine rpm. Forward speed should be adjusted depending on grass conditions and to not overload the power units or the heads. The lower the forward speed the higher the quality of cut and after cut appearance.

Note: The height of cut is gauged by the rear roller. Blade wear, worn cutting unit pivots, bent/damaged cutting unit pins, and bent/damaged arms can affect the height-of-cut setting.

1. Turn the adjusting-nut assembly on both ends clockwise to decrease the height of cut or counter-clockwise to increase the height of cut (Figure 31).

   

   Figure 31

   1. Height of cut
   2. Adjusting-nut assembly

   Important: Do not attempt to unlock the nut assemblies.

2. Ensure that all cutting units are set at the same height of cut by referring to the indicator rings (Figure 32).

   

   Figure 32

   1. Indicator rings

   Note: Refer to Figure 33 for the height-of-cut settings.

   5. 25 mm (1.0 inches)
   6. 20 mm (0.75 inches)

The cutting units may be raised or lowered independently using the bank of 3 lift-control switches.

1. To lower the cutting units, operate the lift-control switches in a downward direction and release.

   Note: The cutting-unit-drive switch must be on to do this, the flail rotor drive engages when the cutting units are approximately 150 mm (6 inches) above ground level. The cutting units are now in ‘float’ mode and follow the ground contours.

   

   Figure 34

   1. Lift-control switches

2. To raise the cutting units, operate the lift-control switches in an upward direction and hold in position 3. If the cutting-unit-drive switch is in the ON position the flail rotor drive disengages.

3. Release the lift-control switches when the cutting units are at the required height.

   Note: The control switches automatically return to position 2 (NEUTRAL) and the arms are hydraulically locked into position.

To raise the cutting units to the limited lift position: momentarily operate the switches in an upward direction.

The flail rotor drive disengages immediately and the cutting units stop raising, approximately 150 mm (6 inches) above ground level.

This operates with the cutting units lowered and rotating.

Auto limited lift in reverse causes the cutting units to rise automatically to the limited lift position when reversing. They return to the floating position when returning to forward travel. The flail rotors continue to rotate during this operation.

To activate, press the auto-limited-lift switch to the ON position (Figure 35).

To deactivate, press the auto-limited-lift switch to the OFF position (Figure 35).

Manual limited lift using the 3 lift-control switches is always available regardless of the position of the auto switch.

The cutting unit drive can be engaged only when the operator is seated correctly, refer toChecking the Operator-Presence-Seat Switch.

Cutting unit drive engagement: Press the top of the cutting-unit-drive switch to the on position (Figure 36).

All cutting unit drives disengagement: Set the switch to the off position (Figure 36).

To lower the cutting units: The cutting unit drive switch must be set to the on position. Operate the lift-control switch(s) in a downward direction. The machine drives when the cutting units are approximately 150 mm (6 inches) above ground level.

A variable hydraulic weight transfer system is provided for improving tire grip with the grass surface—traction assistance.

Hydraulic pressure in the cutting unit lift system provides a lifting force which reduces the weight of the cutting units on the ground and transfers the weight as a downward force onto the tires of the machine. This action is known as weight transfer.

To engage weight transfer: The amount of weight transfer can be varied to suit operating conditions by rotating the weight transfer hand wheel (Figure 37) as follows:

1. Release the valve locknut 1/2 turn counterclockwise and hold (Figure 37).

2. Rotate the valve hand wheel (Figure 37) counterclockwise to reduce weight transfer or clockwise to increase weight transfer.

3. Tighten the nut.

   1. Wear line

5. Ensure that each blade bolt is torqued to 45 N∙m (33.2 ft-lb).

6. Grip each blade and ensure that there is not more than a total of 3 mm (1/8 inch) of free movement in either direction from the rotor. If there is more than a total of 3 mm (1/8 inch) of free movement, replace the blade.

7. Check each pair of opposite blades for a weight difference between them.

   Note: Each pair of opposite blades should not have a weight difference of more than 10 g (0.4 oz).

Refer to the instructions included with the Blade Sharpening Kit.

Ensure that all blade bolts are torqued to 45 N∙m (33 ft-lb).

Inspect the rear guard for wear or damage (Figure 82). Replace the rear guard if it is damaged to prevent objects being thrown into the operator’s area.

1. Raise and support the cutting unit.

2. Grip each cutting unit and check for excessive play from side to side or up and down.

To check for any unusual vibration of the rotor, run the cutting unit at full-engine speed.

1. Start the engine and move the machine to a level, open area away from bystanders.

2. Lower the cutting unit and engage the parking brake.

3. Engage the PTO and run the engine at full throttle while watching for any unusual rotor vibration.

4. If the rotor vibration is unusual, perform the following:

   1. Set the throttle to idle, shut off the PTO, and raise the cutting unit.

   2. Shut off the engine, remove the key, and wait for all moving parts to stop.

   3. Check the cutting unit for the following:

      • Debris preventing the rotor or blades operating correctly and remove any blockages; refer to Clearing a Blocked Rotor.

      • A damaged rotor or worn rotor bearings; refer to Checking the Rotor Bearings.

      • Missing, damaged, unbalanced, or excessively worn blades; refer to Sharpening the Blades and Replacing the Blades.

        Important: All opposing blade pairs must have a similar amount of wear; unbalanced blades may affect the balance of the rotor.

   Important: If you cannot correct the cause of unusual rotor vibration, contact your authorized Toro distributor.

Important: Wear gloves when checking the rotor bearings.

1. Move the machine onto a level surface and engage the parking brake.

2. Raise cutting unit, shut off the engine, remove the key, and wait for all moving parts to stop.

3. Support the cutting unit with jack stands.

4. Grip the rotor at each end and check for excessive end play; if the rotor has excess end play, it may need to be replaced; contact your authorized Toro distributor.

Important: Keep the roller bearings on the cutting units in good adjustment to ensure maximum working life. Excessive roller-end play causes premature bearing damage.

1. Grip the roller and move from side to side and up and down.

2. If there is excessive movement, carefully tighten the nuts at each end of the roller with the wrench just enough to remove any end play (Figure 84).

   Note: The roller should still rotate freely after adjustment. Overtightening the nuts could lead to premature bearing damage.

   Note: Adjust the nuts by an equal amount at both ends of the roller.

   

   Figure 84

   1. Nut

Ensure that the scraper wires are correctly tensioned for maximum working life.

1. Carefully tighten the scraper wire retaining nuts to remove any slack from the scraper wires.

2. Tighten the nuts 4 full turns to correctly tension the wire (Figure 85).

1. Scraper wire retaining nuts

Note: Do not overtighten the scraper wires.

To maintain balance, replace blades only as an opposed pair or a whole rotor at a time. Also replace the bushing, the bolt, and the locknut when you replace a blade. There are 2 service kits available for blade replacement; refer to the Parts Catalog.

1. Raise the cutting unit and secure it with jack stands.

2. Engage the parking brake, shut off the engine, and remove the key.

3. Turn the rotor slowly by hand so that each row of flails are in the desired position and you can easily access them.

4. Use the rotor locking tool (provided in the blade-sharpening kit) to lock the rotor.

5. Remove any debris from the bolt head and the nut and clean the protruding threads with a wire brush.

6. Mark the position of the bolt head so that you can replace the bolts from the same side.

7. Holding the blade in a rag or padded glove, remove the nut, bolt, bushing, and blade (Figure 86).

   Note: If needed, apply penetrating oil to the threads to make the nut easier to remove.

8. Discard the blade, bushing, nut, and bolt.

9. Install a new blade and bushing with a new nut and blade bolt (Figure 86).

   Note: Pay attention to the bolt-head-position markings so that you replace the bolt in the same direction.

10. Torque the fasteners to 45 N∙m (33 ft-lb).

1. Inspect the seat belt for wear, cuts, and other damage. Replace the seat belt(s) if any component does not operate properly.

2. Clean the seat belt as necessary.

Check the machine for loose and missing fasteners.

Note: Tighten any loose fasteners; replace any missing fasteners.

Wash the machine as needed using water alone or with a mild detergent. You may use a rag when washing the machine.

Important: Do not use brackish or reclaimed water to clean the machine.

Important: Do not use power-washing equipment to wash the machine. Power-washing equipment may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. Avoid excessive use of water near the control panel, engine, and battery.

Important: Do not wash the machine with the engine running. Washing the machine with the engine running may result in internal engine damage.
