  • Patent number: 12588588
    Abstract: Lock off assemblies for trimmers are provided. A trimmer includes a working head; a handle assembly connected to the working head by a connecting member; a trigger connected to the handle assembly and movable between an off position and an on position, wherein the trigger being in the on position causes actuation of the working head; and a lock off assembly. The lock off assembly includes a switch connected to the handle assembly and movable between a safe position and an operate position; and a pivotable extension pivotably connected to the switch, wherein the pivotable extension contacts and blocks the trigger when the switch is in the safe position and the trigger is moved from the off position towards the on position, and wherein the trigger is free to move between the off position and the on position when the switch is in the operate position.

  • Publication number: 20250382758
    Abstract: A snow blower may include a frame, a rotatable auger, and a battery compartment. The rotatable auger rotatably may be mounted to the frame. The battery compartment may be attached to the frame to receive a battery pack. The battery compartment may include a battery terminal in selective electrical communication with the battery pack. The battery compartment may also include a guide rail extending above the battery terminal. The deflector plate may be movably mounted above the battery terminal to move between an obstructed position and an unobstructed position. The obstructed position may include the deflector plate extended across at least a portion of the guide rail directly above the battery terminal to cover the battery terminal. The unobstructed position may include the deflector plate horizontally spaced apart from the battery terminal to uncover the battery terminal.

  • Publication number: 20250327257
    Abstract: A snow blower includes a frame defining an auger housing, an inlet opening, and an outlet opening. The outlet opening may be circumferentially bounded about a chute axis. The snow blower also includes a rotatable auger, one or more wheels mounted to the frame apart from the rotatable auger to support the snow blower, a chute body extending from the frame along the chute axis, and a chute drivetrain assembly. The rotatable auger may be mounted to the frame rearward from the inlet opening and below the outlet opening. Additionally, the chute drivetrain assembly may include a chute gear coupled to the frame and defining at least a portion of the outlet opening and a chute lever operatively coupled to the chute gear for rotating the chute body about the chute axis. The chute gear may be configured to rotate the chute body about the chute axis.
