ABSTRACT:
The invention relates to an improvement in a reciprocating mower of the type wherein pivotal reciprocation of the cutting blades is produced by impact blows received from a rotary impactor. In accordance with this invention, two actuating levers are employed to transmit impact forces from a rotary impactor to the movable blades of the mower; one such lever moves the blades in one direction and the other lever effects the return movement of the movable blades. The rotary impactor successively contacts the two levers so that the resulting movements of the cutting blade is a movement in one direction followed by a dwell period, then a movement in the opposite direction followed by a dwell period. A fan, driven by the same prime mover as utilized to drive the rotary impactor, generates air currents which pick up and straighten the grass or other vegetation to be cut by the reciprocating blades and directs the cut vegetation through the plenum chamber of the fan and outwardly through a discharge chute.
