Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, and a steerable-wheel assembly (SWA). The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a detectable magnet fixed to the caster connector to pivot therewith about the pivot axis, and an encoder including a magnetic sensor fixed to the frame apart from the caster connector to detect a pivotable position of the detectable magnet.

Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, a steerable-wheel assembly (SWA), and one or more controllers attached to the frame. The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a first sensor configured to detect a pivotable position of the caster connector, and a second sensor configured to detect the set reference point.

Abstract: A lap bar controller for a lawnmower, the lap bar controller including a framework configured to be coupled to a frame of the lawnmower, the framework defining an opening; a shaft extending through the opening and configured to rotate about a rotational axis defined by a longitudinal axis of the shaft; a control arm coupled to the shaft, the control arm comprising a grip configured to be accessible to a user operating the lawnmower, wherein a user input to the grip causes the control arm to bias the shaft to rotate; and a rotary damper coupled to the shaft, wherein rotation of the shaft causes displacement of the rotary damper, and wherein the rotary damper dampens rotation of the shaft relative to the framework.

Abstract: A lopper or lopper head attachment may include a primary gear, a secondary gear, a ratchet gear, an engagement flag, a dampened lag bolt, and a cutting blade. The secondary gear may be enmeshed with the primary gear. The secondary gear may define a lag groove radially offset form the secondary axis. The ratchet gear may be rotatable about a secondary axis separately from the secondary gear. The engagement flag may be rotatably mounted to secondary gear to move between an unengaged position and a engaged position. The dampened lag bolt may be slidably received within the lag groove to move relative to the secondary gear between a permissive position and a restrictive position. The cutting blade may be in mechanical communication with the ratchet gear to be pivoted thereby, in the engaged position of the engagement flag, to a closed position from an open position.
