A universal crop head assembly is carried at the front of and by a harvester. The new crop head assembly includes a frame assembly, an intermediate multi-crop reel assembly carried by the frame assembly and having selectively extendable and retractable fingers for small grain harvesting. A lower cutter bar assembly is carried by the frame assembly and for cutting grain stalks. An upper forward cutter bar assembly is carried by the frame assembly and supports an upper cutter bar for cutting corn stalks about an upper end, an adjustable air knife assembly for blowing against severed corn stalks upper ends; and a lower draper belt assembly carried by the frame assembly and for moving grain cut by the lower cutter bar assembly.

An automatic lawn compactor includes a case, a battery pack, a controller, a driving device and a trampling device. The battery pack is disposed in the case. The battery pack is configured to supply electrical power to the driving device. The controller is connected with the driving device for controlling the driving device. The driving device is configured to drive the automatic lawn compactor to move autonomously on the lawn. The grass on the lawn is trampled by the trampling device as the automatic lawn compactor moves on the lawn. Through regular trampling the lawn, the grass on the lawn is kept at a certain height to realize the beauty and ornamentality of the lawn. The automatic lawn compactor overcomes the shortcomings of large noise, the difficulty of cleaning up the grass, and the hard work by the existing lawn compactors.

A weeding apparatus includes a handle portion coupled to a blade attachment by a boom. The blade attachment is selectively coupled to the boom and includes a blade having a sharpened edge disposed thereon for severing or otherwise cutting weeds and other undesirable plants. The weeding apparatus is drawn across a surface to capture weeds against the blade to sever the weeds without throwing projectiles at nearby structures, vehicles, amongst others.

A vegetation clearing implement features at least one blade arranged for conveyance over an area of land in a forward working direction. Each blade features a respective serrated cutting edge positioned at a leading side of the blade. The serrated cutting edge lies along an oblique axis that resides at an oblique angle to the forward working direction. The serrated cutting edge features alternating crests and troughs situated along the oblique axis, and each trough has a concave curvature between a pair of adjacent crests. A slope of the concave curvature at its leading end is more parallel to the forward working direction than its trailing end. This provides a gradual increase in the aggression of cut as the equipment moves through the vegetative material to provide for smooth, efficient travel of the implement during a vegetation clearing operation.

The permanent lawn mower, or inground lawn mower, is designed to be an alternative to conventional mobile mowing. Its focus is small grassy areas that are dangerous or impractical to mow by other means. In a first embodiment, the system includes three primary components: a drive unit that supplies rotational motion; a cable that carries rotational motion away from the drive unit, and one or more cutting heads that convert the rotational motion into a cutting action. In a second embodiment, the drive unit is combined with the cutting head, avoiding the need for a cable to carry rotational motion.

A cutting apparatus including a plurality of laser beams for cutting vegetation. The apparatus comprises a housing including side walls being extended generally perpendicular to form a downwardly oriented opening. An electrically powered laser cutting device is positioned centrally within the housing. A transport device is connectable to the housing to provide movement of the housing and laser cutting device along a surface covered by vegetation. The laser cutting device generates at least one laser beam that is directed downward underneath the housing.

A system and method for performing cutting operations with an agricultural implement includes a cutting member capable of cutting plant material supported on the agricultural implement. A vibration source is operatively coupled to the cutting member. The vibration source is configured to generate a vibrational output at an ultrasonic frequency which is transmitted to the cutting member. The vibrational output is propagated through at least a portion of the cutting member to vibrate the cutting member as the plant material is being severed during the performance of the cutting operation.

A reel includes a plurality of bats and an end shield plate mounted on the end of the reel at the crop divider which has a peripheral edge radially inward of an outer tip of the fingers with an apex at each of the bats and portions which are recessed from a straight line joining the apexes. Each of the endmost fingers of the bats has a base which is axially inside the end plate and is bent longitudinally of the reel to define an outer tip which is axially spaced from the base to a position beyond the radial plane of the end plate. A plurality of molded paddle blades are mounted to project outwardly from the end surface to clear crop away from the space between the outer face of the end plate and the divider.

A laser system for agricultural applications, the purpose of which is to broaden, supplement or replace the functions performed by conventional implements, aimed at performing pruning, harrowing, cutting, drying and photostimulation, by means of one or more lasers, with a power-supply module, control module, compressed gas and/or ventilation module, temperature control module, distribution module, laser module, laser light containment and guidance module and wheels, having the advantages of reduced dimensions and weight, being able to move at relatively high speeds with low fuel consumption and low operating costs, being able to operate or not operate in environments with positive pressure to avoid damage to the optical parts or along the path of the laser, the modularity of the system and its adaptability to any size of field.

A crop management apparatus for selectively severing plant items from a plurality of plants. The apparatus comprises: a sensor unit for sensing aspects of the plurality of plants and generating data indicative thereof; a control unit for processing the data to determine a location of a target plant item suitable for severing; a cutter unit comprising at least one selectively deployable cutter for severing the target plant item from its respective plant; and a prime mover for moving the sensor unit and the at least one selectively deployable cutter across the plurality of plants. The control unit outputs a control signal to deploy the at least one selectively deployable cutter at least in part based on the determined location of the target plant item. When the at least one selectively deployable cutter is in a deployed state, severance of the target plant item occurs at least in part based on movement of the prime mover.
