The invention relates to agricultural machinery, in particular to reaper's cutters. The invention is aimed at increasing the quality cutting of mowing and reducing of harvesting losses which is achieved, according to the invention, by using in the reaper's cutter a shaft with a crank mounted thereon having a hole for connecting with a rod, a knife with segments and a finger bar with fingers fixed thereon, the crank has an additional hole for selective rod connection, the crank length is chosen from provisions:1. R= S,in coinciding symmetry axes of pins and segments:2. R= S + 0,5 (S + B+ B);3. R= S + 0,5 (B+ B);at offsetting axes symmetry of fingers and segments to the value 0,5 (B+ B), wherein: S is an axle base between fingers; Bis pin width; Bis width of the segment front edge. |
