ABSTRACT:
Mowing apparatus for connection to the lifting device of a tractor which is powered by the power take-off of the tractor. The apparatus includes a three-point trestle for mounting on the three-point lift device of the tractor, the trestle supporting a parallelogram suspension gear for the mowing component, a gear box and an intermediate telescopic driving shaft for the mowing elements. The parallelogram has a suspension gear including two foldable arm portions whereby the mowing component can be rotated upwardly for transport. The intermediate drive shaft is connected to the mowing component via a gear box. The mowing component is made up of four gear boxes each holding four side-by-side intermeshing pinions, the four gear boxes being connected by a flat frame beam across the top of same with the pinions of adjacent gear boxes being in mesh. Each pinion is journalled in bearings connected to the frame beam thereby suspending same above the bottom of the gear box. A shaft from the pinion extends upwardly from the gear box to engage a disc with a slanting top side, a cutter being mounted at the lower portion of such disc to extend in front of the frame beam which, at its front edge, is curved to correspond with the underlying pinions. A swathboard at the outer end of the mowing component includes a plurality of rake wheels arranged in echelon having sawtooth-shaped circumferences and becoming progressively larger in diameter to the rear. A carrier for the rake wheels is pivotable within limits about horizontal and vertical axes with respect to the frame beam. A screening member is mounted on the frame beam which extends both in front and to the rear of the cutting component whereby, when seen from the side, it has an inverted wide V-configuration, the screen mechanism being resiliently deflectable.
