Abstract

1480796 Mowing implement MULTINORM BV 23 Dec 1974 [28 Dec 1973] 55623/74 Heading A1F A mowing implement I comprises a plurality of rotary cutting members 7 journalled on a housing 3 within which adjacent driving gear wheels 10 attached to the cutting members are connected by at least two pairs of coupling gears 11. The implement is connected to the lifting links 20 of tractor 19 by frame 22 in which is journalled a driving shaft 23 driven by the tractor power take-off. Auxiliary frame 24 is adapted to turn about the horizontal shaft 23 with respect to frame 22 and has at its other end two ears 17. Shaft 23 drives rope drive 26 and hence shaft 21 and bevel gear drive 15 in housing 16. The housing 3 has a troughshaped bottom 4 to which is welded at 6, or bolted, a lid 5. The housing contains driving gear 63 comprising driving gear wheels 10 attached to cutting members 7 by means of shafts 9 and coupling gear wheels 11 arranged between driving gear wheels 10. The coupling gear wheel 11 nearest tractor 19 is driven through elastic coupling 27 and shaft 28 by the bevel drive 15. Each cutting member 7 comprises a disc 36 fixed by screws 34 to a hub 35 and forming a holder to which at least one disc cutter 37 is fastened. The cutters 37 of adjacent cutting members 7 are relatively off-set by 90‹. Several embodiments relate to the way in which cutting members 7 are journalled on housing 3. In one embodiment (Figs. 10, 11 and 12 not shown) the holders of cutting members 7 are formed of hat shaped plates (36) having horizontal brims (48) wherein the cutters (37) can be removed with a key (51). The cutter (37) is bent so that it does not strike plate (36) upon its rotation when a stone is encountered. In another embodiment Fig. 13 not shown the gear wheels 11 are formed by teeth cut in the outer ring of a roller, needle or ball bearing (40). In yet another the cutters (37) are arranged on the undersides of discs (36). The welds in housing 3 may also be located in or below the plane of symmetry 70 of housing 3. The housing may also have a seamless box profile in which the trough 4 and lid 5 are integral with one another.
