  • Patent number: 11769927
    Abstract: The technology disclosed herein relates to a battery housing having a casing with a plurality of sidewalls defining an installation opening and a battery cavity configured to receive a battery. The plurality of sidewalls has a first sidewall having a tab receptacle. A cover extends across the installation opening, the cover has a first end, a second end, and an engagement tab towards the second end. The engagement tab is configured to removably extend through the tab receptacle from outside the casing towards the battery cavity. The engagement tab defines an engagement surface that is configured to frictionally engage the first sidewall in the battery cavity. An adjustable compression mechanism couples the first end of the cover to the casing and defines an axial distance between the casing and the cover. The adjustable compression mechanism is configured to adjustably compress the cover and the casing together across the axial distance.

  • Patent number: 11533842
    Abstract: A grounds maintenance vehicle having a vehicle frame is disclosed. An implement is coupled to the vehicle frame and has a first implement end and a second implement end. A height selection tool is configured to select one vertical position of a plurality of selectable vertical positions, where each vertical position limits a distance between the implement and the vehicle frame. An implement angle selection tool is configured to change the elevation of the first implement end relative to the second implement end and fix the elevation of the first implement end relative the second implement end. The implement angle selection tool has a manually engageable mechanism configured to change the elevation of the first implement end relative to the second implement end when the implement angle selection tool is disengaged.

  • Patent number: 11382263
    Abstract: An articulating mower deck system. The system is adapted to disable power to a blade associated with the wing deck section before the wing deck section begins to lift—from an operating position toward a folded position—yet does not interfere with blade operation when the wing deck section floats relative to a center deck section during normal operation of the deck. Articulating decks of modular construction are also provided, allowing assembly of multiple deck widths with a minimum of modular deck sections.

  • Patent number: 11299040
    Abstract: A low-profile liquid storage tank and vehicles incorporating same. An exemplary low-profile liquid storage tank may define an interior volume having an upper surface that defines an access port, and a lower surface that includes a fluid impingement portion positioned below the access port. The impingement portion may include two or more undulations formed in or on the lower surface of the tank, the undulations adapted to assist with reducing splash-back of fluid added to the tank through the access port.

  • Patent number: 11234353
    Abstract: A soil penetrating apparatus having an automatic tool (e.g., aerator tine) depth control system and method. The system includes an actuator that sets and controls tine depth, a sensor that monitors tine depth, and a controller that controls the actuator in response to the sensor. In some embodiments, the actuator is a hydraulic actuator, wherein once tine depth is set, flow to the actuator is bypassed. A relief may be provided to allow the tines to lift to a shallower depth temporarily when soil hardness exceeds a threshold. The system may then automatically return the tines to the pre-selected depth once soil conditions permit.

  • Patent number: 10836426
    Abstract: A small radius- or zero radius-turn vehicle that may be steered by differentially-driven rear drive wheels and by at least one electronically-controlled, steerable front wheel. A device, e.g., one or more levers, may be provided that controls both speed and direction of the drive wheels. A sensor may be provided that detects a position of the lever(s). A controller may calculate a steering angle of the front wheel based upon the position, and issue a command to an actuator associated with the front wheel. The actuator may rotate the front wheel to an electronically calculated steering angle in response to the command.
