81	Ground wheel driven oscillating harrow	US3700036D	1970-08-07	US3700036A	1972-10-24	REUBER AUGUST
An agricultural implement in which spaced apart, concentric rings carry depending harrow points, the rings being subjected to oscillatory movement during operation by a pitman crank and sway bar actuated responsive to movement of the implement. The rings are adapted to folding to transport positions, and are also elevated for transport.
82	Field cultivator	US3608642D	1969-03-13	US3608642A	1971-09-28	CULP JOHN F
The field cultivator provides support for a cross cultivator unit which comprises a rotative drum mounting a plurality of spring-loaded rake members actuated by a cam member fixed to support means. The cam member engages the orbiting rake members to induce alternating priming and raking stroke of the rake members as the drum rotates. Associated wheels of the field cultivator are linked by synchronizing mechanism to assure alignment of the cross cultivator unit and turning control of the unit as a whole.
