摘要： An autonomous mower including a housing; a mowing module, a traveling module, an information collection device, an energy module, a control module and the control module includes an identification unit, and an alarm module. The autonomous mower has a security patrol working mode in which the identification unit analyzes and judges whether an abnormal object exists in the working area according to the information collected by the information collection device; if the abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside. Therefore, the autonomous mower can achieve a security patrol function in addition to having a function of trimming the lawn. The autonomous mower has multiple uses, so as to save the cost.

摘要： A leaf mulcher includes a carriage, a plurality of wheels rotatably secured to the carriage, and a main housing having a front and a rear. A scoop is removably coupled to the front of the main housing and configured to direct leaves into the main housing to be mulched. The leaf mulcher also includes an impeller housing having an entry and an exit, where the entry of the impeller housing is coupled to a rear of the housing. In addition, the leaf mulcher includes a bag having an intake conduit coupled to the exit of the impeller housing and is configured to receive mulched leaves, and an impeller is within the impeller housing and has an insert and nut. A motor is coupled to the impeller and is configured to spin the impeller to create a vacuum to draw leaves into the impeller housing where the leaves are mulched.

摘要： A green area maintenance system includes an autonomous mobile green area maintenance robot having a treatment tool and a cutting tool differing from the treatment tool. The robot and the cutting tool are configured to allow fixing of the cutting tool to the robot. The system includes a user control device, and has an autonomous operation mode and a cutting operation mode. In the autonomous operation mode the autonomous mobile green area maintenance robot with its treatment tool operates autonomously and the cutting tool is set out of operation, and in the cutting operation mode the cutting tool is fixed to the green area maintenance robot and operable. The robot with its treatment tool and cutting tool are controlled by a user via the user control device, and an operation mode switching device for switching between the autonomous operation mode and the cutting operation mode.

摘要： Various types of lawnmowers are disclosed that include a cutter housing having a cutting chamber and a discharge opening therein. A driving mechanism can be mounted on the cutter housing, and a radius arm can be mounted on or near the blade spindle such that the radius arm is rotatable about the blade spindle. A shutter gate that is arcuate in shape can be mounted on the radius arm so as to rotate with the radius arm between a discharge arrangement and a mulch arrangement. The shutter gate can include a driven element that is driven by the driving mechanism to cause the shutter gate to rotate between the discharge arrangement where the shutter gate allows for discharge of vegetation through the discharge opening, and the mulch arrangement where the shutter gate blocks the discharge opening.

摘要： 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.

摘要： A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.

摘要： An apparatus, system, and method of securing attachments to a utility vehicle, particularly a stand-on, zero-turn mower. The apparatus includes an A-shaped mounting assembly having a base with first and second ends and a tubular member extending outwardly from the first end. The tubular member defines a bore that receives a shaft extending from the attachment. The mounting assembly is positioned vertically above a mower deck on an opposite side of the frame of the mower relative thereto. The second end of the mounting assembly and part of the mower deck are secured to the frame using the same connectors. A hydraulic actuator engages a forwardmost end of the assembly and is actuatable to raise or lower the assembly relative to the frame, pivoting the assembly about the connectors. The attachment and mower deck are substantially simultaneously operable to perform separate landscaping tasks while the mower moves across a surface.
