3. CONTROL PEDALS & LEVERS

3.1.

The front mower stops travelling by depressing this pedal.

3.2.

Depress this pedal, and the front mower starts moving forward. Forward travelling speed is controlled only by depressing it: forward travel accelerates and decelerates by how much the pedal is depressed.

which will cause various troubles such as difficulty in stopping the front mower, changing over between forward travel and reverse travel, etc., which is very dangerous.

When the HST units is out of order, ask your dealer to repair it. The adjustment of neutral position of the HST unit should be done by your dealer.

3.4. DIFF-LOCK PEDAL (4)

To minimize the turning radius of the front mower, the differential gear system is installed, which causes the right and left driving wheels to turn at different speed when turning. On the other hand, it causes the wheels to slip on wet grass or soft ground. In such a case, lower engine speed and depress the diff-lock pedal, and both wheels turn at the same speed, which results in straighter travelling.

(1) Brake pedal

(2) HST forward travel pedal

(3) HST reverse travel pedal

(4) Diff-lock pedal

(5) Parking brake lever

(6) Tilt lever

3.3. HST REVERSE TRAVEL PEDAL (3)

Depress this pedal, and the front mower starts moving backward. The buzzer sounds when the front mower is moving to backward. Reverse travelling speed is controlled only by depressing it: reverse travel accelerates and decelerates by how much the pedal is depressed.

IMPORTANT: After a long time of use, the neutral position of the HST unit may be changed,

CAUTION:

・Never use the diff-lock when travelling at high speeds.

・It is very dangerous to attempt to turn the front mower with the diff-lock pedal depressed. When turning the front mower, be sure to release the diff-lock pedal.

・When the diff-lock is not released despite releasing the diff-lock pedal, stop the front mower immediately and ask your dealer to repair.

3.5. PARKING BRAKE LEVER (5)

Use parking brake lever when parking the front mower. Pull up the lever, and parking brake is applied. In order to maximize the performance of the parking brake, depress the brake pedal, and then apply the parking brake. Push in the top button and lower the lever to release the brake. The parking lamp illuminates with starter switch in the ON position while parking lever is pulled upward. Release the parking lever before starting the front mower and make sure that the parking lamp turns off.

CAUTION:

・ Never start travelling with the parking brake applied, or the brake performance will deteriorate soon or, even worse, the brake system could break down. In the worst case, the brake system may cause fire by heated brake drum if inflammables around the brake system is not properly removed.

・ When leaving the front mower, be sure to apply the parking brake.

NOTE: When the HST forward travel pedal or HST reverse travel pedal is depressed with applying the parking lever, the warning horn sounds.

3.6. TILT LEVER (6)

The steering wheel column is tillable to gain the optimum steering wheel position. To adjust the angles, turn the tilt lock lever anti-clockwise while holding the steering wheel with the other hand, and the lock is released. Select the most adequate angle. Turn the lever clockwise securely to lock the steering wheel column.

CAUTION: Only adjust steering tilt when the machine is parked

4. FENDER PANEL

4.1.

With this lever, the lift link for mower deck is raised or lowered.

DOWN: Move the lever forward, the lift link is lowered. The lever can be held on the lowest position. Return the lever to neutral by hand.

UP: Move the lever backward, the lift is raised. Lever returns to neutral when your hand is released.

CAUTION: When servicing or leaving the front mower, be sure to lower the mower deck to the ground.

IMPORTANT: Do not hold the mower lift lever too long in the UP position, or it may damage the hydraulic system.

(1) Mower lift lever

(2) Collector lift lever

(3) Collector dump lever

(4) Throttle lever

4.2. COLLECTOR LIFT LEVER (2)

CLOSE: Move the lever forward, the container is closed. DUMP: Move the lever backward, the collector is dumped.

4.4. THROTTLE LEVER (4)

With this lever, the engine speed is controlled. LOW: Move the lever backward (towards the " turtle " mark), the engine decelerates.

HIGH:Move the lever forward (towards the " rabbit " mark), the engine accelerates.

5. OTHER CONTROLS

5.1.

Safety Switches

The safety devices are equipped on the operator's seat, brake pedal and engine hood. Before starting engine, engine hood should be closed, the operator should be seated in the operator's seat, and depress the brake pedal fully.

CAUTION: When the engine does not start due to a defective safety switch or does not stop when the operator has left the operator's seat, consult your dealer at once without fail.

5.2. HST UNLOADING BUTTON

Keep pulling up the HST unloading lever while unloading the HST of pressure, which allows the front mower to move without starting the engine. The button should be accessed from right side. (To access from left side, it needs to remove the cover by removing bolt.)

CAUTION: Make sure to move the front mower for only short distance. Do not use it for towing.
