ABSTRACT:
A machine for mowing grass, weeds, vegetation and the like is disclosed herein. The machine is a conventional rotary type lawn mower converted to a sickle-type cutting machine which enables the user to cut vegetation around trees, fence posts, rocks, etc. In use, the blade of a conventional rotary lawn mower is removed, thus exposing the power drive shaft. A torque converter is mounted onto the power drive shaft. The torque converter is connected to a transfer block by means of an endless belt. The transfer block is designed to transfer the circular motion imposed upon it by the power drive shaft and converting this circular motion into a reciprocating movement which is used to power a reciprocating cutting blade. The cutting blades are superimposed upon each other and one of the blades is free to move with respect to the other. The transfer block can be mounted onto the underside of the lawn mower by conventional bolts and includes a driving pulley and a cam which rotates with the pulley, said pulley being driven by the endless belt. The rotating cam engages the moveable cutting blade which results in a reciprocating cutting blade which is then used to cut the vegetation. The transfer block is made such that it is adjustable in a vertical direction and can therefore accommodate mowers of all types, regardless of the deck height.
