| A seed drill having single-disk furrow openers 6 set at an acute angle .alpha. to the direction of travel. The total number of furrow-opener disks is divisible by four, and one half of the furrow-opener disks in each transverse row are set at the acute angle (.alpha.) relative to the direction of travel which is directed to one side, and the half are set at an angle .alpha. which is directed to the other side. | ||||||
| 62 | Press grain drill | US761247 | 1977-01-21 | US4311104A | 1982-01-19 | Ronald M. Steilen; Lester D. Schreiner |
| A press grain drill includes a plurality of opener units mounted on an elongated tow tube and including a plurality of elongated, pivotably coupled elements forming a pair of parallelograms which support a self-penetrating shovel and a press wheel respectively. A first one of the parallelograms permits up and down movement of the shovel relative to the tow tube while maintaining the pitch of the shovel relative to the ground substantially constant. A second one of the parallelograms responds to each movement of the shovel to move the press wheel in the same direction and relative to the shovel so as to maintain the depth of the shovel within the ground substantially constant. Whenever the tow tube which is coupled by pairs of parallel links to an elongated main frame tool bar is raised relative to the tool bar for towing, a lift tube coupled to the links via bracket numbers engages the opener units to lift them relative to the tow tube. | ||||||
| 63 | Planting and fertilizing apparatus | US105827 | 1979-12-20 | US4261593A | 1981-04-14 | Robert R. Yeager |
| A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure film contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear. | ||||||
| 64 | Lifting mechanism with cam | US942066 | 1978-09-13 | US4239086A | 1980-12-16 | Robert R. Yeager |
| A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure firm contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear. | ||||||

| 66 | Seed and fertilizer drill with spring loaded coulters counter-mounted on vertically adjustable beam | US887381 | 1978-03-16 | US4149475A | 1979-04-17 | Alfred J. Bailey; Ronald S. Sargent |
| Seed drill has a row of coulters which are raised and lowered by a beam positioned above the coulters and connected to the coulters by spring assemblies. The beam is journalled for pivotal movement about its longitudinal axis and the spring assemblies are connected to the beam so that some exert reaction forces on the beam having clockwise moments about the beam's pivot axis, and others anticlockwise moments, whereby changes in loading of the coulters can be distributed between the coulters by angular movement of the beam about its pivot axis. | ||||||
| 67 | Means for agricultural seeding | US3611956D | 1969-07-15 | US3611956A | 1971-10-12 | MOORE SAMUEL; JONES FRANK E |
| In agricultural sowing of seeds, seeds are delivered through tubes to slits cut in the ground by a plurality of discs. At least one roller is adapted to compact the ground and close the slits after seeds have been implanted in the slits. The discs and the rollers are carried by arm assemblies mounted on a frame connected to a drawbar and a resilient connection is adjustable to effect relative movement between the frame and the drawbar in a vertical plane to vary the loading applied to the discs.
