Trejon Optimal's hydraulically driven M1250H chain head together with Berti's popular crane arm is the optimal solution for Scandinavian conditions. The chain head has all the features that have made them a sought-after option for users with high demands. The adaptation to Berti's crane arm is made based on the requirements of a professional user. With an arm mower equipped with a chain head, you have an effective tool for clearing grass and brush up to 10 cm behind roads, for example.

The main arm can be hydraulically swivelled in 95° behind the tractor and is also equipped with a hydraulic collision protection system with automatic reset in working position. The tilt link can be hydraulically tilted by as much as 245º to allow the head to work in all conditions. The machines follow the terrain very well with floating position for the head in the tilt linkage and in height via the main arm. The proprietary hydraulic system has a built-in oil cooler as standard and delivers 65 hp of power to the head. The machine operates with two hydraulic circuits to ensure that the head always has full power regardless of arm movement.

The chain head models are supplied as standard with proportional electric control with joystick, electrically infinitely variable ground pressure and separate rotor start/stop.

This model is equipped with an additional joint in the arm for hydraulically advancing the head. This facilitates visibility, especially when driving close to the tractor. Max reach 6,1m and max forward movement 2m.
