| The method for planting potatoes at high speed includes the steps of providing a press wheel behind the seed release mechanism; opening a furrow in a soil; dropping potato seed pieces at spaced intervals in the furrow such that each seed piece or a portion thereof intersects a forward shadow of the press wheel, and catching and decelerating each seed piece against the soil in the furrow thereby reducing set roll in each seed piece. In an alternate embodiment a pair of spaced-apart press wheels are used. These alternate press wheels are mounted astride the furrow in a positive-camber alignment for moving the soil of the furrow against the seed piece. | ||||||

| A seed planting device operable on ground includes a main frame, having wheels, configured to be moved in a planting direction on the ground, a seed hopper, attached to the frame, having a discharge, and a cup-type seed dispenser, having a dispenser axis, disposed adjacent to the discharge of the hopper. The seed dispenser is configured to controllably receive and dispense individual seeds from the hopper and drop the seeds from a seed discharge below the frame. The seed hopper and seed dispenser are pivotally attached to the main frame and configured to rotate about a generally horizontal axis to maintain the dispenser axis in a substantially upright orientation relative to an uphill or downhill planting direction. | ||||||

| A seed belt cup planter includes seed-intercepting indexing pocket structure facing an adjacent cup on the downward run of the belt towards a furrow for orienting the seed released from the adjacent cup relative to the furrow. In one embodiment, the indexing pocket structure is located on the underside of the cups and receives and orients a cylindrically shaped seed such as a short sugar cane billet. The seed pickup side of the cup is shaped to efficiently receive cylindrical seeds as well as round and oval seeds of differing sizes from a seed puddle. A divider located in the seed hopper between adjacent columns of cups helps channel the seed to the cups and limits pressure on the seed puddle. | ||||||

| A potato seed planter in which seeds are loaded into cups on an endless conveyor from a hopper of a seed receptacle. The conveyor is driven on upper and lower sprockets and arranged on the receptacle with the cups in two parallel rows in staggered constant relationship and moving upwardly through the hopper for seed loading. The cups pass around the upper sprocket, invert and enter a contoured tube thereat and descend in an attached discharge tube to a furrow. The cup bottoms are inclined transversely and support the seeds in their descent against the wall of the discharge tube. At the bottom the seeds are discharged from the planter and guided by the transversely inclined cup bottoms are deposited one by one alternately from one row and then the other in the furrow with precision heretofore unacheived. The planter further comprises a wheeled frame and one or more, attached, laterally extending, flexible frames upon which the receptacle is supported. The receptacle is size adjustable and the planter is adaptable to plant in several rows simultaneously. | ||||||

| A potato seed platner in which seeds are loaded into cups on an endless conveyor from a hopper of a seed receptacle. The conveyor is driven on upper and lower sprockets and arranged on the receptacle with the cups in two parallel rows in staggered constant relationship and moving upwardly through the hopper for seed loading. The cups pass around the upper sprocket, invert and enter a contoured tube thereat and descend in an attached dicharge tube to a furrow. The cup bottoms are inclined transversely and support the seeds in their descent against the wall of the discharge tube. At the bottom the seeds are discharged from the planter and guided by the transversely inclined cup bottoms are deposited one by one alternately from one row and then the other in the furrow with precision heretofore unachieved.

| 147 | Conveyor belt spacer for potato planters | US3690511D | 1970-08-17 | US3690511A | 1972-09-12 | WIGHAM JACK H |
| A conveyor belt, sometimes referred to as a cell-belt, in the bottom of the bin of a potato planter having a cup conveyor chain driven by a sprocket on a cup conveyor drive shaft. The conveyor belt is intermittently advanced with seed potatoes thereon to a hopper where the seed potatoes are picked up by the regularly spaced cups on the cup conveyor chain and are thereafter deposited in a furrow in the earth. The means for intermittently advancing the belt is a cam-like action comprised of a sprocket contacted by a revolving arm on a shaft which is indirectly turned by the wheels supporting the planter.
