Abstract

787,214. Mowing machines. TRIMPER, L. L. Nov. 30, 1955 [Dec. 1, 1954], No. 34338/55. Class 6(3). In a tractor-mower wherein the cutter-bar 1, 2 extends centrally across the front of a tractor 7, the cutter-bar is carried by an arm 6 underslung beneath the tractor-chassis, the arm carrying a longitudinal shaft 13, driven from the tractor power take-off, which drives the knife-bar 2 through a universally-jointed pitman 4, 5. The shaft 13 terminates in a crank-disc 19 to which the rear part 5 of the pitman is jointed. The forward part 4 is pivoted, by a vertical pivot 23 to the arm 6, and by a horizontal pivot 21 to the rear part 5, so that it has only a horizontal motion. To obviate entanglement of cut-crop with the pivots 21, 23, the rear pitman-part 5 rigidly mounts an arm 25 carrying a knife 24 which co-operates with the part 5 to shear vegetation. The rear of the arm 6 is supported by the power-operated draught-links 9 of the tractor and the front part rests upon a shoe 27 but is restrained against lateral deflection by a tie-rod (not shown) connected to the tractor chassis.
