Mulch mower with top and bottom cutters and top cutter blade holders

摘要

The mower's top (8) and bottom (2) cutters are both integral. The top cutters are in turn slotted out (18) lengthways below the blade holders (14) and engaged there by holder guide bars (16). Fold-up, quickly removed blade holders (17) are used and the cutting edges (9) of the bottom cutters (2) are corrugated or toothed. This gives a cutting angle of 90 deg , whilst the top cutter's cutting edges (15) are preferably smooth and give a cutting angle between 45 deg and 90 deg . The mower's ground skid, holding arm (5), holders and driver dogs (21) are all preferably screwed to their respective cutters using identical holes from both flat sides of the cutters.
