US 4,362,074 A · Method for cutting vegetation

Abstract

Method for cutting vegetation with a rotating head having a ball member portion and carrying non-metallic cutting line extended into the cutting plane by pushing the ball member against the ground while rotating the head. The ball member portion moves inwardly and a spool carrying coiled cutting line forces a predetermined length of line out of the head. After the cutting line length is extended, the head is secured automatically to the spool for further rotation with the driven spool. A cover is releasably secured to the head by a twist-lock connection to allow the spool to be removed from the head for rewinding, etc. Movement of the spool with respect to the head is regulated by uniform interlocking, straight teeth that are rugged, long wearing and provide positive control without any possibility of "free wheeling" with respect to the spool and the head.

Dependent claims

A method for feeding line in a vegetation cutting apparatus while cutting vegetation growing on turf, comprising:

rotating a spool member at a predetermined speed about an axis in a cutting plane, said spool containing a supply of flexible non-metallic line wound in the direction of rotation of said spool and having a free traveling end portion extending from said spool through an aperture in a head member surrounding said spool and into said cutting plane,
rotating said head member at a speed less than the predetermined speed of rotation of said spool member to force an incremental length of line from said spool and into the cutting plane, and
rotating said head member at the same predetermined speed of rotation of said spool to cut vegetation with said free end of said line including said incremental length of said line.

Dependencies are inferred from the claim text.
