Abstract: A cultivating implement has an elongated frame portion that mounts a row of rotors, each rotor having an upwardly extending shaft and a lower tine. The lower shaft end is a flattened horizontal part with a threaded stub shaft that extends through a central hole in a matching horizontal tine fastening portion. A nut secures the fastening portion to the shaft end part and the nut is surrounded by a space partly defined by side cheeks of the fastening portion. Preferably, the inner side of the tine is concave and the recess formed therein merges into the space. A lug of the fastening portion fits into a recess of the shaft part to further secure the tine to the shaft. The soil working portion tapers downwardly from a curved intermediate portion to a lower tip that can be replaced.

Abstract: An agricultural vehicle has a wheeled frame and a load-receiving chamber enclosed by a framework. A loading mechanism comprising upper and lower gripper members actuated by hydraulic pistons of a control system is mounted at one end of the chamber near an open side. The gripper members can include curved tines, with or without blades, that can be moved to pick up and load crop material in the chamber. A draw bar is pivoted to the frame laterally thereof. The draw bar can be a hydraulically actuated parallelogram linkage that is connected below the gripper members and pivoted to the frame via a connecting piece linkage so that upon actuation, the frame together with the gripper members can be raised and lowered. A conveyor floor can be located at the bottom of the chamber and one or more rotary spreaders located to distribute material from the chamber. The spreaders, conveyor floor and pump in the hydraulic system can be connected to the p.t.o. of a tractor when the latter is hitched to the vehicle's draw bar.
