FEATURES

Levers are located at hands

All the levers used for work are concentrated around the handle.

Main clutch lever

You can easily turn on/off the main clutch and two-stage high/low sub-transmission with a single lever, making it easy to perform high-efficiency work by starting ridge building work at low speed and then at high speed.

Main gear lever

Forward/reverse multi-speed transmission with 4 forward and 4 reverse gears (6 forward and 2 reverse gears for C specification) for a variety of work.
With the same number of speeds even when the handle is in the reverse position, forward movement can be performed quickly with the handle in the reverse position, such as during ridge building work. In addition, the main shift lever can be easily operated with a hand lever.

Off lever

You can disengage the main clutch with light force while holding the steering wheel.

Emergency stop wire

When the wire at the handle is moved, the main clutch lever returns to the "off" position and stops.

Rotary clutch lever

The turning on and off of the rotary can be done at the handle, and work can be done efficiently (when the rotary is installed).

Handle and main gear lever can be turned with one touch according to the work.

In addition, the left and right side clutch levers can be easily replaced without tools according to the direction of the steering wheel.
