Sickle-bar mowers
A sickle-bar mower consists of a multisectional knife that moves in a
reciprocating action across plates (Fig. 6.9). It is designed to cut long
grass, tall weeds and even light scrub along roadsides and other low-
maintenance turfs. Sickle bar units are usually from 1 to 2 m long, often
mounted on tractors and used primarily on areas where mowing is very
infrequent and quality of cut unimportant. Besides roadsides, sickle bars
are best adopted for use on steep slopes and to mow ditches.
