Abstract: A rotary-type lawnmower having unique non-metallic cutting elements carried on a rotating disc-like head with a smooth rim and lower exposed surface without significant projections or recesses capable of inflicting injury to human parts. The lawnmower produces a smooth and even cut equal to rotary metal-blade machines. The cutting elements are tapered pins extruded from flexible polymeric material such as Nylon.RTM. polymer. Each cutting pin has a first portion providing supporting surfaces and an enlargement for securing the pin into the head. The cutting pins extend from the head in a tapered free-traveling end portion to a cutting end located at a cutting plane adjacent the ground's surface. The cutting pins are slidably inserted and removed from the disc.

Abstract: An improved apparatus for cutting vegetation, comprising a motor and a rotating cutting head mounted at the ends of a support tube. One or more flexible non-metallic lines extend into a cutting plane from the cutting head. Unique first and second tubular handle members carrying cylindrical handgrips at their free ends are secured by a clamp to a straight portion in the support tube. These handle members have straight and curved portions arranged in combination so that the handgrips reside in a common horizon and with substantially the same angular displacement at the user's hands with the cutting head positioned directly in front of the user's body. With this improved apparatus the user has a comfortable stance with the cutting head before him and can make equal left and right swings without any undue strain or effort during vegetation cutting.

Abstract: Apparatus for cutting, trimming, and edging vegetation, and the like, is provided with a rotatable disc-like head having at least one string-like cutting member removably attached thereto and replaceably extending from its periphery for cutting adjacent vegetation and the like. Metallic bearing elements for enhancing the cutting life of cutting strings are provided, as well as drive means for increasing cutting efficiency.
