Abstract
An anti-winding assembly reduces or prevents debris from winding on a trimmer and/or makes them easier to remove. The trimmer includes a trimmer head mounted to a rotatable arbor and supporting one or more cutting lines. The anti-winding assembly includes a collar positionable between the trimmer head and an adjacent trimmer component, and a shield positioned radially outward of the collar. The shield covers gaps between the collar and the trimmer head and between the collar and the adjacent trimmer component. The assembly reduces exposure to pinching gaps and to powered rotating parts that enable tight windings that can accumulate to lock trimmer rotation.

An anti-winding assembly for a trimmer, the trimmer including a trimmer head mounted to a rotatable arbor and supporting one or more cutting lines, the anti-winding assembly comprising:
- an adjacent trimmer component attachable to and cooperable with the trimmer;
- a collar positionable between the trimmer head and the adjacent trimmer component, wherein the collar is free-floating such that the collar is displaceable relative to the trimmer head and the adjacent trimmer component;
- and
- a shield positioned adjacent the collar, the shield being positionable to cover gaps between the collar and the trimmer head and between the collar and the adjacent trimmer component.
An anti-winding assembly for a trimmer, the trimmer including a trimmer head mounted to a rotatable arbor and supporting one or more cutting lines, the anti-winding assembly comprising:
- an adjacent trimmer component attachable to and cooperable with the trimmer;
- a collar positionable between the trimmer head and the adjacent trimmer component;
- and
- a shield positioned adjacent the collar, the shield being positionable to cover gaps between the collar and the trimmer head and between the collar and the adjacent trimmer component, wherein the shield is a guide that contains a position of the collar, and wherein the collar is free floating with a clearance between the trimmer head and the adjacent trimmer component.
A trimmer comprising:
- a rotating trimmer head;
- at least one cutting line coupled with the trimmer head;
- a trimmer component disposed adjacent the trimmer head;
- and
- an anti-winding assembly that prevents debris from winding between the trimmer head and the trimmer component, the anti-winding assembly including:
- a collar positioned between the trimmer head and the trimmer component and engaging the trimmer head and the trimmer component, wherein the collar is free-floating such that the collar is displaceable relative to the trimmer head and the trimmer component, and
- a shield positioned adjacent the collar, the shield covering gaps between the collar and the trimmer head and between the collar and the trimmer component.
A trimmer comprising:
- a motor driven rotating trimmer head;
- at least one cutting line coupled with the trimmer head;
- a glider disk disposed on a ground side of the trimmer head;
- and
- a first anti-winding assembly positioned between the trimmer head and the glider disk, the first anti-winding assembly including a first collar positioned between and engaging the trimmer head and the glider disk, wherein the collar is free-floating such that the collar is displaceable relative to at least the trimmer head.
