The invention relates to a regional lawn maintenance management system and method, and relates to the technical field of lawn maintenance management, mainly including lawn maintenance terminal equipment, evaluation equipment, intelligent computing equipment, community terminal equipment, data visualization equipment, connected through a communication network, the management equipment, database and commercial operation equipment can fully evaluate the users condition before the user conducts regional lawn maintenance management. The intelligent computing equipment and evaluation equipment generate suitable data based on the evaluation data information and/or historical evaluation data information before, and after the maintenance of the lawn based on the users maintenance plan information and feedback from the lawn maintenance terminal equipment, the maintenance plan information is continuously optimized in subsequent maintenance or data processing to generate a set of targeted maintenance plans, and the comparison is obtained at the regional level. The macro regional turfgrass data provides the function of regional turfgrass maintenance and decision-making, so that turfgrass management can be regionalized, refined, intensive and intelligent.

A rotary lawn mower has one or more grass cutting blades that are rotatable in opposite directions about a vertical axis or axes. Each blade is double edged having front and rear cutting edges on each end of the blade. Each blade end has a front sloped face inboard of the front cutting edge and a rear sloped face inboard of the rear cutting edge. These faces create air flow within the cutting chamber when cutting grass regardless of the direction of rotation of the blade. The direction of rotation of each blade is reversed to switch between discharge and mulching modes of operation. A flow director has a curved vertical guide wall that guides the grass clippings through a discharge opening in the discharge mode and that guides the flow of grass clippings away from the discharge opening in the mulching mode.

A cutter housing for a lawnmower can include first and second cutting chambers with first and second chamber walls and first/second discharge openings. First and second ring gates that have openings and blocking segments can be concentrically placed within respective first and second chamber walls, and rotatably attached to the cutter housing. The first and second ring gates can be rotated between: (a) an opened position in which the first/second ring gate is positioned with the first/second ring opening having a first overlap with a first/second discharge opening to provide a discharge mode, and (b) a closed position in which the first/second ring gate is positioned with the first/second ring opening having a decreased overlap, relative to the first overlap, with the first/second discharge opening to provide a mulch mode. The ring gates can be stopped at intermediate positions to provide a partial mulch mode or partial discharge mode.

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.

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.

A gardening tool with identification function including an operating unit and a working unit is provided. The operating unit includes a first main body, a first electrical connector, and an operating device. The first electrical connector is set at one end of the first main body. The operating device includes a processor electrically connected to the first electrical connector. The processor stores operating parameters. The working unit includes a second main body, a second electrical connector, a motor, and a work piece. The electrical property of the second electrical connector is corresponding to one operating parameter in the processor. When the second main body is connected to the first main body, the second electrical connector is electrically connected to the first electrical connector. The processor selects one operating parameter according to the electrical property of the second electrical connector to control the output rotational speed or power of the motor.

Various types of lawnmowers are disclosed that include at least one cutter housing having a chamber wall with a discharge opening therein. The mowers can include a rolling shutter formed of multiple steel sheets held together by pins. In discharge mode, the rolling shutter can be wrapped around a roller cylinder. In mulching mode the rolling shutter can extend to close off the discharge opening of the mower.

The disclosed subject matter is directed to a lawnmower that can include a cutter housing with a first chamber wall defining a first cutting chamber. A first discharge opening can be located in the chamber wall, and the cutter housing can include a slot arrangement. A conversion assembly can include an adjustable wall slidably attached to the cutter housing so as to be selectively movable within the slot arrangement between an opened position and a closed position to place the lawnmower in either a discharge mode or a mulch mode (or somewhere in between).

The invention relates to an adjusting device, which includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device of the present invention has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.

An electrically actuated mulch control lever includes an upper plate and a lower plate pivotably mounted together on a top surface of a mower deck. A compression spring is retained between the upper plate and the lower plate urging the upper plate and the lower plate to pivot together. An electric linear actuator is connected to one of the plates, and a mulch gate hinge is attached to the other plate.
