1. An apparatus for keeping down groundcover between parallel rows of plants, comprising:
- two chopping blade rotors that are rotatable in a common plane, each around a rotational axis perpendicular to the ground, wherein a distance between the rotational axes is adjustable in a direction perpendicular to the plant rows even when rotational areas of the chopping blade rotors overlap;
a separate electric motor assigned to each of the chopping blade rotors;
devices for controlling the electric motors so that that collisions between the chopping blade rotors are avoided;
a housing having an open bottom and which holds the chopping blade rotors, the electric motors being mounted directly and coaxially with the chopping blade rotors on housing parts of the housing; and
, a carrier device that connects the housing to a vehicle, the housing parts being shiftable relative to the carrier device, only in a plane parallel to the common plane.

Abstract
An apparatus (mulcher) for keeping down groundcover between parallel rows of plants, especially rows of wine grape or fruit plants, with two chopping blade rotors rotating in one and the same plane, each around an axis perpendicular to the ground. The distance between the rotational axes is adjustable in a direction perpendicular to the plant rows even though the rotational areas of the chopping blade rotors may overlap. A separate electric motor is assigned to each of the chopping blade rotors, and devices are provided to control the electric motor so that that collisions between the chopping blade rotors are avoided.
