Installation position
A position that the driver's right foot can quickly approach, preferably to the right of the brake pedal
Preferably installed in front of or to the right of the driver, and in a position that is convenient for the driver to operate
Easily accessible on the driver's seat Close position
Easily accessible position on the driver's seat
Operation method
The engine can only be started when the following conditions are met:
①The main transmission is in neutral or disengaged position
and the auxiliary transmission is also in neutral or disengaged position②The main clutch is disengaged
③The driver is sitting in the driver's seat
Step on the pedal forward or downward to increase the engine speed
The moving direction of the joystick is parallel to the longitudinal axis of the driven vehicle In the plane, the direction of movement should be away from the driver (usually forward or upward to increase engine speed)
The joystick should be able to remain in the off position without human power

Convenient position for the driver to operate
Operation method
When equipped with a steering wheel, clockwise rotation should make the vehicle turn right, counterclockwise rotation is for left turn brake pedal The direction of movement of the plate is generally forward or downward to engage the brake. When the wheeled tractor is equipped with brake pedals for left and right braking respectively, the brakes should be interlocked to prevent excessive deviation due to braking when driving in a straight line. Pulling action is preferred. When equipped with left and right independent hand-operated mechanisms, the brakes should be interlocked to prevent excessive deviation due to braking when driving in a straight line. When moving backward or upward, it is engaged. When the brake pedal is pressed down or forward, it is engaged. Pressing the pedal forward or downward disengages the clutch and moving backward disengages the clutch. Moving the outer pedal forward or downward should cause forward movement and increase the forward speed, and moving the inner pedal forward or downward should cause reverse movement and increase the reverse speed. Moving the joystick forward or upward is engaged. Moving the joystick backward or downward is disengaged. The engagement and disengagement of the cutter should be independent of the traction system. The directions of engagement and disengagement shall be clearly indicated by signs

Installation position
The drive clutch release device of the lawn mower should be installed between the engine and the cutter. If the cutter is directly installed on the motor, the release device should be installed between the motor and the power supply (battery).
According to the provisions of JB/T6677.1
Position convenient for the driver to operate
Device convenient for the driver to operate
Installation position
The driver can only operate from the normal position
Position convenient for the driver to operate
Position convenient for the driver to operate
Position convenient for the driver to operate
Position convenient for the driver to operate
Position convenient for the driver to operate
Position convenient for the driver to operate
The movement direction of the front end of the control device is downward for descent, and upward for lifting. The direction of its movement should be clearly indicated by a sign
Moving the control device forward or downward is descent, and moving backward or upward is lifting. The direction of movement shall be clearly indicated by a sign
Method of operation
Start by hand
Start by hand
Move the joystick forward to increase the engine speed
The joystick has a locking device to prevent accidental operation of the starting device
Move the joystick to the off position. The joystick should remain in the off position without any control. When the joystick is moved in the opposite direction of travel, the power is completely disconnected. When the joystick is moved forward, the power is temporarily disconnected
When reverse gear is engaged, reverse gear can only be engaged when the driver applies continuous pressure on the joystick. Moving the joystick forward or downward is forward movement. There should be a fixed neutral position
Moving the joystick backward or upward is reverse. There should be a fixed neutral position. When the joystick passes the neutral position, the operating force changes significantly.
