for tractors from 45 hp

Very flat and smooth surface, it slides under low-hanging branches without damaging branches and fruits

The STO rotary mulchers are preferred in orchard implementation.

Extremely flat and with a smooth surface it slides through under low-hanging boughs without damaging branches and fruit. However, the outstanding characteristics of the STO also ensure optimal mulching results for green area maintenance and on managed grassland with fruit trees.

As desired, the mulched material is distributed in the tramline behind the implement, or uniformly distributed laterally in the tree strip. The desired distribution can be adjusted on the discharge flaps.

Hydraulic lateral adjustmentx

For use in mulch/spray combination, the VO rotary mulcher is factory-equipped with a gearbox through drive. With the floating hitch (rocker arm) the tongue weight of the sprayer is transferred to the tractor.

The STO 260 rotary mulcher – working width 2.61 m – is equipped with four rotary cutters and has a large overlap. In addition a lateral skid for optimal ground adaptation and removable front track rollers.

The basic implement STO 230 is equipped with three rotary cutters, the basic implement STO 260 is equipped with four rotary cutters. Thus a large overlap is achieved, evidenced by an extremely clean cutting pattern. The cutters are mounted on cutter carriers so that the blades can be cost-efficiently replaced.
