Abstract:
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.
Abstract:
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.
Abstract:
A ground surface treatment vehicle and systems and methods using the same. In some embodiments, the vehicle may be adapted to autonomously or semi-autonomously identify and optionally treat target areas such as divots on turf surfaces. The vehicle may identify the target area via onboard or remote sensors and autonomously treat the target area by providing a treating material such as infill, seed, particulate matter, and liquids.
Abstract:
A handle assembly for an autonomous vehicle such as a lawn mower is provided and may include a cradle adapted to receive a mobile computer. The mobile computer may communicate with a controller carried by the mower. The handle assembly may be configured in both an autonomous mode position and a manual mode position. The vehicle may operate autonomously when the handle assembly is in the autonomous mode position, and be adapted to move under manual operator control, e.g., for perimeter training, when the handle assembly is in the manual mode position. Methods for training the mower and apparatus for storing the mower are also provided.
Abstract:
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.
Abstract:
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.
Abstract:
A vehicle combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.
Abstract:
A reel mower has a drive and mounting system for easily and quickly installing a turf grooming attachment. A pair of bearing supports on opposite sides of the reel mower frame provides laterally spaced stub shafts between which the through shaft of the attachment can be nested. A pair of identical clamps releasably couples the opposite ends of the through shaft of the attachment to the adjacent stub shafts. Installation and removal of the clamps is sufficient to install or remove the attachment without requiring disassembly or lateral movement of the bearing supports or of the stub shafts rotatably journalled therein.
Abstract:
A turf management system includes an irrigation system for providing water to the turf at a turf site, and an irrigation evaluation system for evaluating the performance of the irrigation system. The irrigation evaluation system segments the turf site into irrigation management units, where each of the irrigation management units includes at least one sprinkler head. Qualities of the turf are measured to generate collected data points. The data points are used by the irrigation evaluation system to compute a value for the turf in each of the irrigation management units. The values can then be used to identify irrigation management units having common characteristics. The values can be used to define irrigation management zones for controlling the irrigation system.
Abstract:
This invention relates to a mower and a tracked implement tohat convert from one to the other by coupling a mower unit or a tracked unit to a common drive unit. The drive unit is thus used in both products to provide cost savings in the purchase of the equipment. In the tracked unit, a cab for enclosing the operator's station is part of the tracked unit and gets mounted to the drive unit when the tracked unit is coupled to the drive' unit. A pair of idlers rotate on pivot axes that are fixed relative to a pivotal idler support that carries the idlers. The pivot point for the idler support is chosen to prevent track elongation when the tracked unit climbs obstructions such as a curb. In the mower unit, a relatively heavy cutting deck is used and spring biased weight' transfer arms transfer some of the deck weight to the mower frame .
