Abstract
A trimmer and a trimmer head for use with the trimmer, the trimmer head including a body rotatable about an axis, the body defining a plurality of axially spaced channels each sized to receive at least a portion of a trimmer line therein, and a clamping mechanism in operable communication with at least two of the axially spaced channels to selectively retain a trimmer line positioned within any one of the at least two axially spaced channels. The trimmer head may include a wear disk pivotable relative to the trimmer head body. In addition, a release button of the clamping mechanism may be arranged on the body to provide additional clamping force when the trimmer head rotates about the axis.

A trimmer head for use with a trimmer, the trimmer head comprising:
- a body rotatable about an axis, the body defining a plurality of axially spaced channels each sized to receive at least a portion of a trimmer line therein;
- and
- a clamping mechanism in operable communication with at least two of the axially spaced channels to selectively retain a trimmer line positioned within any one of the at least two axially spaced channels.
A trimmer head for use with a trimmer, the trimmer head comprising:
- a body rotatable about an axis, the body defining one or more channels sized to receive a trimmer line therein;
- a clamping mechanism in operable communication with at least one of the one or more channels to selectively retain a trimmer line within the at least one of the one or more channels;
- and
- a wear disk rotatably coupled to the body.
A trimmer head for use with a trimmer, the trimmer head comprising:
- a body rotatable about an axis, the body defining one or more channels sized to receive at least a portion of a trimmer line therein;
- and
- a clamping mechanism in operable communication with at least one of the one or more channels to selectively retain a trimmer line in the at least one of the one or more channels, the clamping mechanism including
- a clamping member operable to apply a clamping force to a trimmer line in the at least one of the one or more channels, and
- a release button operable to move the clamping member from a clamping position, in which the clamping member applies a clamping force to the trimmer line, toward a release position, in which the clamping force is reduced, the release button being arranged on the body to provide additional clamping force when the trimmer head rotates about the axis.
A trimmer comprising:
- a frame;
- a motor supported by the frame and operable to rotatably drive a drive shaft;
- and
- a trimmer head supportable on the drive shaft for rotation with the drive shaft, the trimmer head including
- a body rotatable about an axis, the body defining a plurality of axially spaced channels each sized to receive at least a portion of a trimmer line therein, and
- a clamping mechanism in operable communication with at least two of the axially spaced channels, the clamping mechanism including
- a clamping member operable to apply a clamping force to a trimmer line in one of at least two of the axially spaced channels, and
- a release button operable to move the clamping member from a clamping position, in which the clamping member applies a clamping force to the trimmer line, toward a release position, in which the clamping force is reduced.
