Abstract: A lawn mower includes a hollow shaft, a cutter blade, flaps, a belt type continuously variable transmission, and a transmission mechanism. The cutter blade extends along a horizontal line which is perpendicular to the hollow shaft. The flaps are provided for the cutter blade. Each of the flaps has a flap angle changeable along the horizontal line. A control force converter unit of the belt type continuously variable transmission converts a displacement force of the movable sheave relative to the fixed sheave in an axial direction into a control force that controls the flap angle of the flaps. The transmission mechanism is accommodated inside the hollow shaft, and transmits the control force to the flaps.

The device is mountable on the front of a tractor and includes a frame carrying a plurality of generally upright but forwardly inclined columns. Each column carries a cutting assembly including a cutting blade mounted on a shaft rotated by a hydraulic motor. The cutting blade is comprised as a spherical segment and has a leading edge disposed in slightly penetrating relationship relative to the soil surface.

Deflector units are mounted at the bases of the columns to deflect cut beans into a windrow located between pairs of counter-rotating blades.

Abstract: Straw spreaders are normally controlled manually by the operator and it is therefore extremely difficulty to continually adjust the speed of the spreader so that the straw layer is reasonably even because the density of the straw varies continuously across the average field. The present device includes a rheostat sensor at the straw walker that controls the speed of the orbital motor driving the spreader blade assemblies. This results in a relatively even spread of straw taking place regardless of the variation in straw density as the motor slows down under a light load and speeds up when heavy straw is encountered. The operator can, of course, control the on/off functions from the cab if, for example, it is desired to spread alternate swaths.
