A control arrangement for a lawn mower that selectively prevents operation of the lawn mower in the reverse direction with the lawn mowing mechanism operating. The arrangement includes structure (e.g., a bypass switch) actuatable by a lawn mower operator to permit the operation of the lawn mowing mechanism while the mower is propelled in the reverse direction as a bypass mode. Circuitry interacts with engine operation circuit to cause the operation circuit to selectively terminate operation of the engine when the lawn mowing mechanism is operating, as indicated by a lawn mowing mechanism switch, and the motive drive arrangement is selected to propel the lawn mower in a reverse direction, as indicated by a motive drive arrangement switch, except when the bypass mode is established. The circuitry also terminates the bypass mode when the lawn mower operator is absent as indicated by a operator present switch.

Apparatuses and methods are provided for controlling a self-propelled machine, such as a lawn mowing machine, including a housing, an engine attached to the housing, a variable speed transmission, and a twist-grip throttle control. The variable speed transmission can propel the mowing machine, and the twist-grip throttle control can be operatively connected to the variable speed transmission for controlling the variable speed transmission. Self-propelled speed of the mowing machine can therefore be controlled by operating the twist-grip throttle control. The twist-grip throttle control is designed to integrally retain an operator presence control so that only a single control needs to be used by the operator during use of the mowing machine.

The invention relates to a lawn pruning appliance, in particular to a lawn pruning and patterning robot and a control system and method thereof. The robot comprises a vehicle body, a walking mechanism, a steering mechanism, a pruning mechanism and wheels, wherein the vehicle body comprises a cover and a base, the cover and the base are connected to form a closed cavity, and the wheels are arranged on the outer side of the cover; the walking mechanism is arranged in the closed cavity, and a transmission shaft of the walking mechanism penetrates through the cover and is connected with the wheels; the steering mechanism is arranged in the closed cavity, and a connecting shaft of the steering mechanism penetrates through the cover and is connected with the wheels. The pruning mechanism comprises a mowing motor, a blade shaft and blades, wherein the mowing motor is connected into the closed cavity, the blades are arranged under the base, and the blade shaft penetrates through the base and is connected with the mowing motor and the blades. Through the mutual coordination effect of the steering mechanism, the walking mechanism and the control system, a traditional manual operation mode is abandoned; the patterning capability is realized through the mutual coordination effect of the pruning mechanism, a lifting mechanism and the control system.

The invention discloses an intelligent lawn mower based on laser radar map construction, and relates to lawn mowers. The intelligent lawn mower solves the problem that the work efficiency is low because workers need to manually measure and input parameters again when different lawns are cut. The technical scheme main points are as follows: the intelligent lawn mower also comprises a main control module, a feature information module, a laser radar scanning module, a walking control module and a lawn mowing control module; when a lawn mower body starts, the main control module sends out start signals and activates a uniform speed circumferential direction rotation unit and a laser transmitting and receiving unit to construct an electronic map; and the main control module controls the walkingcontrol module to continuously walk and revise the electronic map at different positions. The intelligent lawn mower based on laser radar map construction is free of manual input, and the lawn mowerbody can automatically scan and automatically establish and update the electronic map for the cutting use.

The invention discloses a lawn mowing device driven by a screw to ascend and descend and special for afforestation. The lawn mowing device comprises a main support, an auxiliary support, a lifting frame, a cutting machine and a trimming knife, a rack is slidably mounted on a horizontal sliding rail through a sliding rod, a second driving motor is fixedly mounted on the right side of the inside ofthe lifting frame through a support, a driving bevel gear is mounted on an output shaft of the second driving motor in an interference fit manner, a driven bevel gear is connected on the left side ofthe driving bevel gear in a meshed manner, a half gear is concentrically and rotatably mounted on the driven bevel gear, a main connection rod is fixedly welded on the lower side of the rack, the cutting machine is fixedly mounted on the lower side of the main connection rod, and the trimming knife is mounted on an output shaft of the cutting machine. Through threaded fit between a screw and a slider, height of the lifting frame can be adjusted, ground clearance of the trimming knife is adjusted indirectly, and lawn mowing length is determined accurately; by combining rotation of a roller, andautomatic moving for trimming can be realized; compared with manual trimming, the lawn mowing device is more orderly in lawn mowing, and beautiful degree is increased.

The invention discloses household lawn mowing equipment. The household lawn mowing equipment comprises a cutter body, an infrared sensor, a smashing box and a material storing box. The cutter body is connected with a telescopic rod through a rotary shaft; a rack is disposed at one end of the telescopic rod; the smashing box is fixedly arranged at the top end of the rack; and a spiral rod is arranged inside the smashing box. The household lawn mowing equipment is simple in structure, low in manufacturing cost and high in practicability. The cutter body is connected with the telescopic rod through the rotary shaft, so that the cutter body is convenient to rotate and can easily cut off grass; the infrared sensor is disposed at the bottom end of the rack and can sense evenness of the ground so that the telescopic rod can be controlled in time, and the rack is disposed at one end of the telescopic rod, so that the damage to the cutter body due to ground unevenness is prevented; a suction fan is disposed at one end of the interior of the smashing box and can suck cut-off grass clippings into the smashing box through pipelines; the spiral rod is disposed inside the smashing box and can further smash the grass clippings, so that reusing is facilitated, saving is achieved, and the environmental friendliness is achieved; and rolling wheels are arranged, so that the mowing equipment is convenient to push and travel, labor is saved, operation is simple, and the equipment is convenient to use.

A combination yard maintenance apparatus used for lawn mowing, leaf clearing and snow blowing comprises a blade assembly having an elongated support member for rotatably mounting to a drive shaft and two shovelling surfaces disposed at opposite ends of the elongated support member extending from the elongated support member downwardly and laterally opposite one from the other. Each shovelling surface has a lower edge with a cutting edge, an upper edge, an inner edge and an outer edge. The present invention also provides a clutch mechanism for engaging and disengaging an input shaft from an output shaft comprising a first and a second threadable engagement associated with the input shaft and output shaft respectively, and an initiator for inducing the engagement of the first and second threadable engagements. A friction-drive self-propelling system is also provided, comprising a driving wheel and a friction disk wherein the driving wheel has central recessed portion.
