Abstract: A self-propelled lawn care appliance for aerating and subsoiling the ground below a turf includes a chassis, an implement with piercing tools movable up and down for piercing the ground for subsoiling, and an optical lane recognition device comprising at least one camera and an image processing unit. In a first mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a hole pattern of an area of the ground previously treated by the lawn care appliance and, based thereon, a boundary of a previously treated lane. In a second mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a defined boundary of the deposited soil material of a ground area previously treated by the lawn care appliance and, based thereon, the boundary of a previously treated lane.

Abstract: A mobile soil cultivation appliance includes a chassis with at least one drive axle for driving a travel movement of the soil cultivation appliance over the soil, a drive unit with a drive shaft, a work implement which is configured to be ascended and descended relative to the chassis and includes a drive shaft and at least one soil working tool which is movable for soil working upon rotation of the drive shaft. The drive shaft is connected to the output shaft by means of a power transmission means to allow the drive shaft to be driven by the drive unit, and the drive unit is connected to the work implement as a counterweight for the work implement in such a way that the drive unit descends when the work implement is ascended and ascends when the work implement is descended.
