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.

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.

A power seeder may include a frame, one or more wheels, one or more blades capable of cutting into soil, an engine capable of powering the one or more blades, and a seed hopper. The seed hopper may have an opening capable of dispensing seed located forward of the one or more blades. The one or more blades may rotate in an opposite direction to a forward rotation of the one or more wheels. In some embodiments, the seeder may further include a handle for adjusting the height of the one or more blades, a plurality of interlocking teeth, and a spring. The spring may provide a load to counteract the force of gravity on the one or more blades. The aerator may also include a flap located between the opening and the one or more blades.

A vehicle includes a chassis, a pair of wheels rotatably mounted to the chassis, and a jack stand having an extended portion and a support portion. The extended portion has a longitudinal axis. The support portion is located at a longitudinal end of the extend portion. The jack stand is arranged on the chassis to be slidable with respect to the chassis in a direction generally parallel to the longitudinal axis for movement between a deployed position, wherein the support portion is located vertically below a bottom surface of each wheel, and a stowed position, wherein the support portion of the jack stand is located vertically above the bottom surface of each wheel.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

In general, the subject matter described in this disclosure can be embodied in an aeration tine that includes a mounting portion removably connectable to an aeration apparatus and defining a central axis; and a curved blade portion that extends longitudinally from the mounting portion to a tip of the aeration tine and that is operable to fracture soil and form an aeration pocket. The curved blade portion includes a concave first edge and an opposed convex second edge, wherein the concave first edge includes (i) a proximal first edge portion, (ii) a distal first edge portion proximal the tip of the aeration tine, and (iii) a middle first edge portion between the proximal first edge portion and the distal first edge portion, the middle first edge portion closer to the central axis than both the proximal first edge portion and the distal first edge portion.
