  • Patent number: 9872421
    Abstract: A sod harvester can include an inclined stacking conveyor from which slabs of sod are removed for stacking on a pallet. The direction of incline of the stacking conveyor can be opposite that of one or more inclined conveyors used to convey sod from a cutting head to the stacking conveyor. Therefore, slabs of sod can ascend along the one or more inclined conveyors and then descend along the inclined stacking conveyor from which they are removed by the stacking head. The stacking head can also be inclined to correspond with the incline of the stacking conveyor. By inclining the stacking conveyor and the stacking head, the stacking head does not need to move vertically when removing slabs of sod from the stacking conveyor.

  • Patent number: 9422129
    Abstract: A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer.

    Abstract: There is provided an improved, simple and effective, powered hole-cutting apparatus, otherwise referred to as a power cup cutter, comprised of a USGA approved cutting cylinder modified with an internal plunger and an elongated threaded rod, whereby the cutting cylinder is driven into the soil by the rotation of the rod which is attached to an electric drill for easy and effortless cutting of a hole on golf course greens. With a straightforward reversal of the drill rotation, extraction of the soil plug from the newly formed hole and subsequent insertion of the soil plug into the previous hole will restore the golf course greens for golf play. The ability to cut holes quickly and efficiently is essential for golf course maintenance, but contemporary manual-operated cup cutters have fallen short of offering an efficient means of both the extraction and the insertion of the soil plug. Current methods are highly labor-intensive and require 25-30 minutes for each hole.

  • Patent number: 7121356
    Abstract: A “sod saver” tool for digging to acquire an object buried in the ground, and a non-metallic scraping tool utilized when carefully examining the soil. The sod saver tool includes a main cylindrical body rotated about its longitudinal axis for digging a substantially cylindrical plug of soil from the ground, the object being contained in the plug of soil, and a plurality of circumferentially-disposed resilient non-metallic fingers located at a bottom portion of the main cylindrical body. When the digging of the plug is being performed, the resilient fingers tend to spread radially outward from the longitudinal axis of the main cylindrical body, being deflected away from directly hitting and scratching the buried object, tend to generally direct the soil upwardly into the main cylindrical body, and tend to cause the plug to be substantially-compacted and cylindrical. The compacted plug may be easily reinserted into a hole in the ground.
