***Attention! There are extra costs for the mounting to the carrier vehicle! Mounting has to be run by retailers.

As a standard:
Single-lever electronic proportional control – very suitable for mounting in the cabin of the tractor.

The single-lever joystick control gives the operator the option of controlling the height and extension of the extension arm with one lever. At least two cylinders can be controlled simultaneously and continuously. Thus, a precise and even control of the arm is given.

Optimum design:
By arrangement with BMS 3530 Front no visual obstruction occurs during the transport.

Ease of work:
A mechanical parallel guiding of the extension relieves the driver: With a change in display, the position of the working device remains unchanged.

Pruning shears – equipped with a guide finder and serrated lower blade for a clean cut. Particularly suitable for pruning up to Ø 30 mm.

Suitable mulching heads
