Undergrowth mulcher with hydraulic drive, for front attachment on wheel loaders, crawler track vehicles, large boom mowers or excavators


With its PH undergrowth mulcher humus brings to market a new powerhouse for green area maintenance and forestry work. The undergrowth mulcher with hydraulic drive has been especially developed for attachment on implement carriers with radio remote control. But it also suitable for other hydraulic carrier vehicles, e.g. for front attachment on wheel loaders, crawler track vehicles, large boom mowers or excavators.

The housing has a system angle bracket for fast and flexible attachment on a wide variety of carrier vehicles. Optionally the humus PH can be attached with a three-point linkage Cat. II on PTO shaft-driven carrier vehicles in front attachment and rear thrust, with 540 or 1000 rpm. Flexible tool use (cutter systems) enables different applications and implementation conditions. The rotor’s tool configuration can be easily swapped out and matched to the application. The hydraulic front flap with counter-cutters is standard equipment. The counter-cutters in the machine ensure better reduction of the mulched material.
The housing of Hardox steel promises a long service life and is designed for professional use. An ingenious tool system guarantees an optimal cutting pattern: Ideally suited for green area care and forestry work, for rough terrain; it mulches undergrowth and branches without any problems.

The optimally balanced rotor with the B70 and B80 cutter systems ensures less wear on the bearings. The high rotor speed ensures high productivity and an optimal work result.

The rotor has a cutting depth limitation that prevents excessive depth in the material to be mulched, thus excessive reduction of the rotor speed is prevented. This a particular advantage with low-power carrier vehicles, in maintaining the rotor speed.

B70: The B70 cutter is the ideal partner for tasks with light ground contact! Thanks to its single-edged, sharp and hardened blade, you obtain the best finechopping results. The B70 cutter is suitable for all ground conditions, all types of vegetation and all types of undergrowth strata.

B80: Triple-edged carbide tool with offset cutting edges for wear-intensive and sandy applications. Minimal force requirement thanks to diagonally inserted carbide plates and an additional wear guard on the holder.
