Abstract: A golf green hole-making device has longitudinal, radial, and angular directions, and includes a cutting cylinder, a structure, a weight, a weight propulsion device, a soil expulsion piston, a piston driving mechanism, and an expulsion activating mechanism. The cutting cylinder has an open end that is freely movable longitudinally. The structure includes a guide with which the weight engages to move along a weight path between first and second endpoints, when propelled by the weight propulsion device, causing the weight to strike the cutting cylinder and urge the cutting cylinder in the longitudinal direction. The soil expulsion piston moves inside the cutting cylinder along its axis. The piston driving mechanism transfers force from the weight propulsion device to the soil expulsion piston to drive the soil expulsion piston towards the open end. The expulsion activating mechanism engages and disengages the piston driving mechanism in relation to the weight propulsion device.

Abstract: Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds into contact with stator bars at angularly spaced positions around the axis of the rotor. U-shaped bars are symmetrical and can be reversed when the second leg is worn for extended life. Parts of the rotor and stator which are radially outward of other parts are formed with a higher resistance to wear approximately proportional to the radius so that the wear characteristics of the different parts are matched to the velocity of the particles impacting the different portions to generate symmetrical wear throughout the structure.
