Design
The Bracke T26.b is designed to enable it to closely follow uneven terrain. The machine’s hydraulics allow sideways arm movements and the disc to turn about its vertical axis if overloaded. The hydraulics are load-sensing and are connected to the prime mover.

Machine control
The control system, is based on a PLC platform and communicates over a CAN bus. With the new display, the control system is very user friendly. The disc trencher is fitted with sensors that send information the control system about, for example, the prime mover’s speed, the angle of the discs and the position of the arms. The control system has eight programmable operating programs chosen from the controls in the cab. The display is used to make settings in the control system and read information from the scarifier. The control system keeps track of the scarified area and the distance covered, for both individual sites and in total, as well as the number of hours worked.

Scarification
The operator controls the Bracke T26.b from the cab. Depending on changes in the site conditions, one of the eight preset programs are chosen. The control system gives the operator variation possibilities to set arms and discs on different widths and angles. It is also possible to vary ground and lifting pressure or operate with a float mode. The Bracke T26.b can be set to work continuously or intermittently.
