TimeCutter® ZS 4200T Riding Mower

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.

The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 9).

The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.

The Smart Speed ^TM Control-System lever, located below the operating position (Figure 28), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow.

Figure 28

1. Smart-speed lever

To change speeds, do the following:

1. Move the motion-control levers to neutral and outward to the PARK position.

2. Disengage the blade-control switch.

3. Adjust the lever to the desired position.

The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass.

Trim

This is the lowest speed. The suggested uses for this speed are as follows:

• Parking

• Heavy, wet grass mowing conditions

• Training

• Trimming grass

Tow

This is the medium speed. The suggested uses for this speed are as follows:

• Bagging

• Mulching

• Towing attachments

Mow

This is the fastest speed. The suggested uses for this speed are as follows:

• Normal mowing

• Moving the machine

The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

Note: The transport position is the highest height-of-cut position or cutting height at 114 mm (4-1/2 inches) as shown in Figure 29.

You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 13 mm (1/2 inch) increments. The height of cut is controlled by the lever located to the right of the operating position (Figure 29).

Figure 29

Whenever you change the height of cut, adjust the height of the anti-scalp rollers.

Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas.

Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you or bystanders avoid injury. Refer to your local ordinances for trailer and tie-down requirements.

Selecting a Trailer

Warning

Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 32).

• Use only a full-width ramp; do not use individual ramps for each side of the machine.

• Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

• Ensure that the length of the ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This ensures that the ramp angle does not exceed 15 degrees on flat ground.
