Abstract
1383851 Mowers A J VOGELENZANG 26 April 1972 [11 May 1971 17 March 1972] 19263/72 Heading A1F The cutters 3 and associated stationary double edged cutter blade 4 of a mower are respectively mounted on a drive shaft 7 by means of bearings 1 and 8 and the bearings 1 are inclined to the shaft’s axis to cause the cutters 3 to oscillate about respective vertical and longitudinal axis. The drag between the inner and ‘outer races of the bearings 1 urges the blade 4 and the cutters 3 together and the inner races are rigidly connected to the shaft 7 by sleeves 11. The bearings 1 are arranged along the shaft 7 so that at any instant each cutter 3 has a counterpart moving in anti phase relationship and so thereby inertia forces are balanced. The blade 4 may be segmented, with each section supported on the shaft 7. Each cutter may be attached to its respective bearing 1 by a holder having a leaf spring to resiliently bias the cutter into its working position but allow deflection upon the cutter encountering an obstacle. The cutters 3 may have a trapezoidal (narrow side uppermost) or triangular vertical cross-section or a V-shaped vertical cross section (Fig. 11) in which the angle subtended by the arms of the “V” varies from the rear to front end by an amount equal to twice the angle which the cutter is tilted about its longitudinal axis as it sweeps over one edge of a tooth of the blade 4. In another embodiment, the horizontal angle contained between the cutting edge of each cutter 3 and the associated tooth edge of the blade 4 is maintained constant by the tooth having a rounded as opposed to a rectilinear cutting edge. The drive shaft 7 may have a circular or polygonal cross section and the sleeves 11 attached thereto by splines or screw threads. A bellows like sleeve is fitted over the drive shaft 7 to prevent entanglement of cut crop.
