摘要： A method and apparatus for treating turf to reduce the general soil density in which turfgrasses grow and thus promote turf growth and turf drainage which includes injecting through the turf into the soil a pattern of jets of generally incompressible liquid at a jet pressure and jet spacing to provide a lateral dispersion of the liquid within the soil such that the liquid dispersion from adjacent jets coact with one another to lift and fracture the soil. A plurality of small diameter nozzles are mounted on a movable frame generally transverse to the direction of travel of the frame. A pressurized fluid source is mounted on the frame and connected through a control device to the nozzles. The control device control the flow of liquid from the pressure source to the nozzles to produce periodic, relatively small cross-sectional, slugs, or jets, of liquid from the nozzles through the turf into the soil. The pressure on each slug of liquid is such that the liquid penetrates through the turf into the soil and also disperses generally laterally within the soil. The spacing of the nozzles and the speed of travel of the frame are such the lateral dispersion of each slug of liquid coacts with adjacent slugs to lift and fracture the soil, thereby reducing the compaction, or general density, of the soil and promoting turf growth and drainage.

摘要： A hydraulic system (30) suitable for raising, lowering, floating and locking a cutting deck (16). Hydraulic circuit (30) preferably includes a back pressure system (40) for automatically, or manually, applying a preferred back pressure to hydraulic cylinders (24) to "float" decks (16). Connected to back pressure system (40) is an actuation system (42) which can automatically or manually act on back pressure system (40) to change the back pressure depending on conditions. For example, it may be desirable to increase the back pressure when mower (10) encounters a hill to transfer more weight from the cutting unit (16) to the traction vehicle (12) of mower (10).

摘要： 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.

摘要： A mulching mower has at least one generally enclosed cutting chamber in which a rotatable cutting blade is carried for rotation in a generally horizontal cutting plane. The side wall which defines the circumferential boundary of the cutting chamber is not perfectly circular with respect to the axis of blade rotation. Instead, the chamber is stretched or elongated with respect to the blade tips over the rear half of the chamber to be obround to the rear of the chamber. This enhances use of the mower as a mulcher. In addition, grass deflecting members are desirably used in the rear half of the chamber to further enhance the mulching action provided by the chamber.

摘要： A ground working vehicle having a vehicle frame (102) is disclosed. An implement (114) is coupled to the vehicle frame (102) and extends between a first implement end and a second implement end. The implement (114) is adjusted to alter the rake angle between the first and second implement ends, to modify internal dimensions of the implement (114), and/or to include a kick-down baffle. Further, the implement (114) may be adjusted manually, remotely, or automatically. For example, one or more actuators (150) can be coupled to the implement (114) to adjust as desired by the user. Further, one or controllers (152) can automatically adjust the implement (114). Specifically, the implement (114) is adjusted to optimize operating parameters such as, e.g., runtime of the vehicle and/or quality of cut.

摘要： Autonomous machine navigation techniques may determine vision-based pose data based on feature data and object recognition data extracted from images. The vision-based pose data may be used to generate a three-dimensional point cloud that represents at least a work region. The vision-based pose data may be used to determine an operational vision-based pose relative to the three-dimensional point cloud.

摘要： Embodiments of the present disclosure are directed to lawn mowers (e.g., walk power mowers), having a deck supported for travel over a ground surface. The deck may support a prime mover having an output shaft adapted to power a cutting blade contained within a cutting chamber defined by the deck. The mower may also include a drive system to power the cutting blade. In some embodiments, the cutting blade may attach to the output shaft of the prime mover via a friction interface such that, upon unintended blade contact with obstacles, the blade may rotationally slip relative to the output shaft. Moreover, the mower may include a blade brake clutch (BBC) adapted to permit selective activation and deactivation of the blade independent of the prime mover.

摘要： Apparatus, systems, and methods for directing an autonomous robotic vehicle such as a lawn mower relative to a work region. In some embodiments, the vehicle travels in a random pattern within a travelling containment zone of a lesser size than the work region. The travelling containment zone may move or travel across the work region such that, over time, the travelling containment zone travels over most all of a working surface of the work region.
