41	Oscillating agricultural implement	US22364472	1972-02-04	US3837407A	1974-09-24	JAN DE KONING C; OOSTERLING P
Improvement of an agricultural implement, e.g., fertilizer spreader or harrow, at least comprising a frame to be attached to a vehicle, e.g., agricultural tractor, at least one tool, e.g., spreading nozzle or harrow beam, carried by the frame and oscillatingly moving with respect to the frame, and a driving element rotating about an axis of rotation and driving the tool via a fork, wherein a stalk of the fork is beared rotatably in the driving element outside the axis of rotation and wherein teeth of the fork are beared hingeably about a hinge axis to the tool. For facilitating, assembling and dismantling of the fork in the driving element the fork is beared in a bearing bush removably attached to the driving element and the driving element comprises a recess for letting through the stalk of the fork with removed bearing bush, said fork hinging about the hinge axis.
42	Harrow	US3791453D	1971-12-01	US3791453A	1974-02-12	OOSTERLING P
In a harrow comprising reciprocating driven harrow beams directed transversely to a forward movement of its frame, said harrow beams are connected to each other and to the frame by means of parallel levers swingably beared on the frame and to the harrow beams. In order to compensate differences in the distances between the engaging points of the levers on the harrow beams and/or differences in the lengths of these levers, the levers consist each of two lever parts which are beared round a common axis swingably with respect to each other on the frame.
43	Sonic hand cultivator	US3747687D	1967-06-24	US3747687A	1973-07-24	BODINE A
A sonic hand cultivator comprised of an orbiting-mass oscillator which in turn drives or vibrates a resonator coupled to a plurality of spikes or tines which are caused to resonantly vibrate as they embed themselves in the ground.
