Abstract: A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution member with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor. The mechanical transmission includes a horizontal shaft connected to two vertical shafts for rotating the distribution members via bevel gears and is contained in a hollow tube with gear boxes on either end which maintain the axes and levels of the vertical shafts and distribution members in fixed relative positions.

Abstract: A soil cultivating implement has a central frame part that extends substantially horizontally perpendicular to the direction of operative travel of the implement, the frame part has lateral arms tiltably connected to its opposite ends about pivot pins which extend in the direction of travel. Each lateral arm has a corresponding group of power drivable rotary soil working members indirectly connected to it and, a strong but simple frame which resists the high operating forces without deformation. The inner ends of the arms are each held between respective spaced apart cheek plates so as to be surrounded on three sides by those two cheek plates and by a respective connecting piece that rigidly couples the pair of cheek plates to one another beneath the corresponding arm.
