CONTROLS

Throttle Control

The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade switch is pulled out (see Engaging the Mower Deck).

In order to increase or decrease the engine speed, the control is moved forward or back respectively.

Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs.

USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging.

Throttle control

Hour Meter

The hour meter displays the total operating time.

It will flash CHG OIL (Change Oil) at 50 hour intervals. The flash duration is one hour before and one hour after the interval. The CHG OIL icon will come on

and shut off automatically. The hour meter cannot be manually reset.

Parking Brake

IMPORTANT INFORMATION

The machine must stand absolutely still when applying the parking brake. Always set the parking brake before dismounting. Release the parking brake before moving the mower.

The parking brake is found below the front seat. Pull the lever upward to activate the brake and push downward to release it.

Lifting Lever for the Mower Deck

The deck cutting height is achieved with the foot pedal. To lift the deck, press the foot pedal forward.

To lower the deck, apply pressure to the top side of the foot pedal and allow the pedal to pivot while allowing the lift arm to rotate to the rear of the unit.

To stop at the desired cutting position, rotate the pedal down into the notch in the height plate. The cutting height range is from 1½" (38mm) to 5" (127mm) in

½" (13mm) increments. The heights are measured from the ground up to the blade tip with the engine not running.

IMPORTANT INFORMATION

In order to obtain an even cutting height it is important that the air pressure in all four tires is the same 15 psi (1 bar).

Accessories

For mulching, there is a BioClip attachment available. The BioClip is mounted underneath the mower deck and includes a discharge cover and blades.

OPERATION

Read the “Safety Instructions” section and the following pages if you are unfamiliar with the machine.

Training

Zero turn mowers are far more maneuverable than typical riding mowers due to their unique steering capabilities.

We suggest that this section be reviewed in its entirety prior to attempting to move the mower under its own power. Additionally, we suggest when first operating the mower, use a reduced throttle speed and reduced ground speed by NOT moving control levers to the furthest forward or reverse positions during initial operation, or until operator becomes comfortable with controls. We also suggest first time users, or new users to Zero Turn mowers to become familiar with the mower’s movement on a hard surface, such as concrete or blacktop PRIOR to attempting to operate on turf. Until operator becomes comfortable with mower controls and zero turning capability, they may damage turf due to overly aggressive maneuvers.

To move forward and backward

The direction and speed of the mower’s movements is effected by the movement of the control lever(s) on each side of mower. The left control lever controls the left wheel. The right control lever controls the right wheel.

IMPORTANT INFORMATION

When control levers are in the reverse position they return to neutral when released. This may cause the mower to suddenly stop.

First time users should push mower (see “Moving by

Hand” in the “Operation” section) to an open, flat area, without other people or vehicles/obstacles nearby. In order to move unit under its own power, the operator must be in the seat, start engine (see “Before Starting” in “Operation” section), adjust engine speed to idle, disengage parking brake, do not engage blades at this time, rotate control levers inward. As long as

the control levers have not been moved forward or backwards, mower will not move. Slowly move both control levers forward slightly. This will allow mower to start moving forward in a straight line. Pull back on

control levers to the neutral position and mower should stop moving. Pull back slightly on control levers, this will allow mower to start moving backwards. Push forward on control levers to the neutral position and mower should stop moving.

Steering

To turn to the right

While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction.

To turn to the left

While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction.

To zero turn

While moving in a forward direction, first pull both control levers back until the mower stops or slows dramatically.

Then by alternating one lever slightly to the forward position and the other in the reverse position.

English-24

OPERATION

Before Starting

Read the sections “Safety Instructions” and

“Controls” before starting the machine.

Perform the daily maintenance before starting (see Maintenance Schedule in the Maintenance section).

Check that there is sufficient fuel in the fuel tank.

Adjust the seat to the desired position.

The following conditions must be fulfilled before the engine can be started:

The driver must be seated on the seat.

The blade switch for engaging the mower blades must be depressed.

The parking brake must be on.

Both steering controls must be in the locked

(outer) neutral position.

Starting the Engine

1.Sit on the seat.

2.Raise the mower deck by depressing the pedal forward to the locked position (transport position).

3.Activate the parking brake.

OPERATION

8.Press in and turn the ignition key to the start position.

9.When the engine starts, immediately release the ignition key back to the run position.

IMPORTANT INFORMATION

Do not run the starter for more than 5 seconds each time. If the engine does not start, wait about 10 seconds before retrying.
