The Monster T-BG disc harrow is a compact disc tillage machine available in the working width sizes of 2.5, 3.0,3.5, 4.0,4.5, 5.0,5.5, and 6.0 m. The two rows of offset discs to work the soil are arranged for an aggressive attack and ripping, thorough mixing and breaking of stubble in a single pass. In this tillage type, the disc attack is modified with the working depth that is in turn changed by operating the hydraulic coupling height on the tractor; this changes the pressure on the disc, the disc angle to the tillage direction; this also enables a more aggressive drawing of the discs into the soil. The overall machine is compact and easy to manoeuvre on the field and on the road. The machine is also very convenient in operation. With a machine this versatile, the stubble and harvest residues are thoroughly mixed.
