Abstract

This invention relates to an improvement in a reciprocating mower of the type wherein two longitudinal rows of juxtaposed cutting teeth are relatively reciprocated by impact blows received from a rotary impactor. In accordance with this invention, the rotary impactor constitutes a relatively massive fly wheel and impact rollers are mounted on the outer periphery of the fly wheel member. Each of the rows of cutting teeth is connected to an actuator bar, and the two actuator bars are respectively disposed in spaced parallel relationship surrounding the periphery of the fly wheel and thus contacted by the impact rollers during each revolution of the internal gear. In accordance with another embodiment of the invention, the same motor driving means is utilized to propel a fan which is connected by a suitable housing to remove by air draft vegetation cut by the cutting teeth from such teeth and deposit same in a suitable receptacle.

Claims

1. A reciprocating mower comprising two rows of horizontal cutting teeth disposed in juxtaposition and relatively movable through a cutting stroke, resilient means operating between said two rows of cutting teeth to normally hold said teeth in an aligned open position, a pair of horizontally spaced parallel actuator bars respectively connected to the end portions of said cutting teeth rows, a flywheel rotatably mounted on a vertical shaft disposed between said actuator bars, a pair of diametrically opposed impact roller means mounted on the periphery of said flywheel and adapted to respectively impact said actuator bars during each revolution of said flywheel to momentarily shift said cutting teeth rows to their closed position, a fan mounted on said shaft and co-rotatable with said flywheel, thereby increasing the inertia mass of said impact roller means, and housing means for said fan for removing cut vegetation from said cutting teeth by air currents generated by said fan.
