A high efficiency turf maintenance apparatus having low power consumption and good cutting performance including a bagging apparatus for turf clippings is presented herein. A blade configuration is disclosed to provide lift and to propel turf clippings from a mow deck to the bagging apparatus. Further, the blade configuration can be implemented with minimal increase in power consumption, allowing the bagging apparatus to be utilized with an electric motor power source with little or no impact on battery life.

Lawnmowers are provided. A lawnmower includes a seat configured to receive a lawnmower operator; a mowing deck having one or more cutting implements and a discharge chute; and a bagging system in fluid communication with the discharge chute through a tube, wherein the lawnmower has a first configuration when the tube is coupled to the lawnmower, wherein the lawnmower has a second configuration when the tube is not coupled to the lawnmower, wherein the tube is disposed at a lateral side of the lawnmower in the first configuration, wherein the lawnmower defines a maximum lateral width in a lateral direction, and wherein the lateral width is less than 38 inches in both the first configuration and the second configuration.

A stand is provided for storing a grass bagger or collection assembly removed from a lawn mower. The stand includes a base, which may include wheels, and a pair of upstanding arms to which the grass collection assembly is mounted. The arms include receivers, such as pins or plates, to which the frame of the bagger assembly is hooked. A fastener extends through at least of the arms and the bagger frame to prevent accidental falling of the frame from the stand. The stand includes upstanding members over which the bagger chute can be mounted to store the chute in an upright position adjacent the grass collector frame and bag. A shelf may be provided on the stand to store other bagger accessories.

A dethatcher includes a frame having a front and a rear end, a handle coupled to the frame and movable between a use position and a storage position, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the handle is in the use position, the handle extends away from the front end of the frame and when the handle is in the storage position the handle extends toward the front end of the frame.

A method for assisting a compaction-appropriate distribution of harvested material in a flat silo includes providing a silo vehicle having a control unit, ascertaining a dry-substance density to be achieved via the control unit, determining a maximally producible compaction pressure via the control unit, ascertaining a maximally permissible layer thickness via the control unit for the implementation of a distribution-and-compaction process, determining a layer thickness currently being applied during the implementation of the distribution-and-compaction process in a location-specific manner via a GPS receiver, comparing the maximally permissible layer thickness and the layer thickness currently being applied in the location-specific manner via the control unit in order to ascertain a target layer thickness, and driving a regulating device of a distribution tool provided on the silo vehicle to assimilate the layer thickness currently being applied to the target layer thickness via the control unit in an automated manner.

Uneven distribution of grass clippings in a grass clippings receptacle of a lawn mower can be minimized. A lawn mower includes: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive mowed grass clippings; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to open and close the grass clippings transport passage and an actuator configured to open/close-drive the shutter; a controller configured to control the shutter device; and a speed sensor for detecting a travel speed of the lawn mower, wherein the controller is configured to open/close-control the shutter device based on the travel speed.
