Abstract: The low-profile, lightweight tiller of compact, uncluttered design is adapted to be rigidly mounted upon the rear, powered lifting links of a garden tractor so as to be raised and lowered by the latter between transport and ground-working positions. Driving power for the transverse rotor of the tiller is obtained by a direct drive connection with the power takeoff shaft of the tractor. A right angle gearbox located inside the open bottom housing for the rotor is supported by the rotor shaft itself and has an upwardly and forwardly directed input shaft that connects directly with a telescoping, universal joint drive line connection with the power takeoff shaft.

Abstract: A rotary tiller device with a rotor disposed for rotation about a vertical axis is adapted for mounting on the lift arms of a mobile vehicle and includes a yieldable arm suspension mechanism and spring tiller teeth depending downwardly from the rotor, both of which in combination with each other provide uniform tillage depth control of the device. The rotor assembly can be moved laterally inwardly and outwardly with respect to the frame, and the beam can be adjustably swiveled about a vertical axis such that the rotor can be positioned to the left side, right side, or front of the frame or vehicle.

Abstract: A plurality of cages are arranged side-by-side on a frame in one or more horizontally spaced rows and if desired in spaced vertical tiers. The commonly facing sides of each spaced row include coverable access openings and poultry confined in the cages are removed through the openings onto a generally horizontally moving conveyor movable vertically adjacent the cage openings to each tier. Preferably, the conveyor is an endless belt type and each tier includes horizontally spaced rows vertically spaced above each other, the conveyor being movable vertically between the rows.

Abstract: A cutting blade is carried on a shaft rotatable about an axis positioned adjacent a row crop. The blade extends across the longitudinal centerline of the row and cuts plants as the machine moves forward until a sensing means registering on forwardly positioned plants actuates the knife and causes it to rotate rearwardly along the row and away from the next plant in the row to be retained. The rotation continues until a knife portion is now positioned on the front side of the plant to be retained and a portion of the knife extends rearwardly along the side opposite the axis of rotation of the blade. The machine continuing to move forward will again clear plants from the row until the sensing means actuates the blade to rotate again thereby causing predetermined plants to be retained while plants inbetween are thinned out.
