A method of maintaining artificial turf using a turf maintenance robot. The artificial turf comprises an artificial turf carpet, wherein the artificial turf carpet comprises turf fibers which form an artificial turf surface. The artificial turf fibers have a grain. The artificial turf comprises artificial turf infill distributed between the artificial turf fibers. The turf maintenance robot is a self-driving robot, wherein the turf maintenance robot comprises a memory for storing turf grain data, descriptive the grain of the artificial turf fibers. The method comprises brushing the artificial turf surface by the turf maintenance robot. The turf maintenance robot performs the brushing dependent upon the turf grain data.

An apparatus for a vehicle used for positioning sod strips includes a structure for mounting on the vehicle frame and a pushing plate slidably mounted to the structure. The pushing plate is arranged to be abuttable to an edge of a sod strip. A pair of cylinders are operatively mounted between the structure and the pushing plate to slide the pushing plate away from the structure to laterally shift a sod strip to tighten up seams between adjacent sod strips. The pushing plate slides in a lateral direction that is perpendicular to the straight ahead driving direction of the vehicle.

An apparatus for a vehicle used for positioning sod strips includes a structure for mounting on the vehicle frame and a pushing plate slidably mounted to the structure. The pushing plate is arranged to be abuttable to an edge of a sod strip. A plurality of guide arms extend outwardly of the pushing plate to overlie a sod strip being positioned to prevent upward buckling of the sod strip. A pair of cylinders are operatively mounted between the structure and the pushing plate to slide the pushing plate away from the structure to laterally shift a sod strip to tighten up seams between adjacent sod strips. The pushing plate slides in a lateral direction that is perpendicular to the straight ahead driving direction of the vehicle.

A sand bunker rake/infield groomer vehicle having a frame; a plurality of wheels to traverse a driven surface, wherein the wheels are rotatably mounted to the frame; a power source mounted to the frame; and a rear attachment structure attached to the frame, wherein the rear attachment structure provides a joint enabling rotation; a bracket including a shaft wherein the bracket is configured to cooperate with an associated rake/grooming attachment; and a pivoting bracket mounted to the frame.

A device and method for loosening compacted soil, a plurality of tubular devices made from a resiliently compressible material having a hollow hub with a series of radially and circumferentially curving blades extending from the hub, a plurality of devices arranged in an array in soil to cause loosening of the soil as it seasonally expands and contracts and causes compression and subsequent expansion of the devices which in turn loosens the soil sufficiently to aerate the soil.
