for tractors from 45 hp

Especially designed for the cultivation of the blossom strip in orchards

Beneficial insects (e.g. bees, butterflies) and predators of aphids and spider mites (ladybugs, aphid lions) are encouraged through blossom strips with indigenous flowering meadow plants and wild herbs in orchards. Through its lift-out rotary cutter the humus OMB enables the user to leave a 40 cm blossom strip standing. Likewise, scarification of the blossom strip (mulching the flower heads to stimulate growth) is also possible. Before harvesting fruit and in the headland the rotary cutter can be lowered, so the complete width of the row can be mulched.

With the humus OMB any desired working position can be freely selected, thanks to its solid design and its variable working width adjustment of 2.19 m to 3.07 m. The working width is infinitely variable and hydraulically adjusted from the tractor. Both swing discs can be adjusted synchronously or separately. Thus the OMB rotary mulcher offers an absolutely reliable and economic possibility for mulching the tree strip and implementing organic cultivation. Thanks to its smooth surface, the OMB slides easily under low-hanging branches.

The OMB rotary mulchers move on large track wheels with a wide contact area. They can be adjusted in height.

The humus OMB has a minimal power requirement and can be operated starting at 45 hp.

The OMB basic implement is equipped with 3 rotary cutters. Thus a large overlap can be achieved, if desired.
The cutters are mounted on cutter carriers so that the blades can be cost-efficiently replaced. It is important to leave the mulching material long-fibred and to ensure a deposit of the cuttings in the tree strip. The mulched material should cover the open tree strip and serve as a protection against drying out and as nutrient supply.
