The invention relates to an apparatus (10), preferably an autonomous robot apparatus, for mowing grass. The apparatus (10) has a plurality of cutting devices (20) for mowing the grass. The apparatus (10) has a plurality of carrying arms (22) which are arranged offset with respect to one another with regard to the transverse axis of the apparatus (10), and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices (20). The apparatus (10) has a plurality of supporting elements (24) which support in each case one of the plurality of carrying arms (22) on an underlying surface, and are arranged in front of the respective cutting device (20) with regard to a forward moving direction (V) of the apparatus (10). The apparatus (10) can have the advantage that the leading supporting elements (24) do not push any cuttings in front of them, and a risk of the apparatus (10) being jacked up is decreased.

A machine for soil tillage to be arranged on a towing vehicle, wherein when the towing vehicle is travelling in a travel direction an area of soil can be tilled with a soil tillage tool in an intermediate space between at least two obstacles, wherein the machine has a control device with which the soil tillage tool is pivotable into and out of the intermediate space and/or is movable in a transverse direction towards or away from the machine into the intermediate space, wherein the control device comprises an adjusting device which causes the soil tillage tool to pivot in and out and/or to move in the transverse direction by an adjustment amount after detection of an obstacle.

A tractor mounted tiller/cultivator system that includes right and left swing arms pivotally attached to tractor chassis, right and left cutting head assemblies mounted on the swing arms, each including a right disc motor driving a rotary disc mounted on a distal portion of the swing arm and operatively coupled to the motor. Ground-engaging cultivation wheels surround the rotary disc, and an annular guard prevents unwanted contact of the wheels with vines or trunks of vines and trees. A drive mechanism lowers and raises the swing arms to put the cultivation wheels into engagement and disengagement with ground and to rotate said swing arms about their longitudinal axes. User controls operatively connected to the swing arms, cutting head assemblies, and drive mechanisms enable a user to finely tune the movement of the cutting heads into and out from rows of trees or vines.

A thermoplastic composition including a mixture of three particular and different polyolefins, including one of a polyamide-grafted polyolefin having particular polyamide grafts (type and quantity), for example, a polyamide-grafted polymer having a polyolefin trunk containing a residue of at least one unsaturated monomer and a plurality of polyamide grafts. Also, a thermoplastic film and, more specifically, a film for encapsulating a photovoltaic module incorporating the polyamide-grafted polyolefin composition.
