Rotary cutters also known as slashers, bossiekappers or haycutters are widely used to cut veld grass and crop grasses such as eragrostis. They are defined by their cutting width ranging from 1M to 3M.
Generally a smallholder would make use of 1, 1.2 & 1.5M cutters. The cutter is hitched to the tractors three point linkage and driven by a PTO (Power take off) shaft sized to suit the implement.
A standard rotary cutter is dragged by the tractor and runs on a set of skid liners. A good quality slasher has four sturdy blades and a flail plate of at least 10mm thick bennox steel. The blades fit between the flail plate and a strut to swing back when hitting an obstacle.
