Abstract
A planter or seeder is drawn rectilinearly over the field and has sowing blades like casters or tailwheels which are caused to swivel from side to side so that the rows defined by the sowing blades have an undulating or sinusoidal pattern.
Claims9
A seeder comprising:
- a support displaceable over ground to be seeded in a direction of advance of the seeder;
- a seed box on said support;
- a plurality of seed tubes on said support distributing seed from said seed box;
- a plurality of sowing blades engageable in said ground and each connected to one of said seed tubes for sowing seed distributed to the respective blade by the respective seed tube;
- means for pivotally mounting each of said sowing blades tailwheel fashion on said support for swiveling about a respective substantially vertical swivel axis;
- and
- means for imparting side to side movement to said axes transverse to said direction, whereby each of said sowing blades moves in an undulating pattern as said support is displaced over said ground in said direction.
A method of operating a seeder comprised of a support displaceable over ground to be seeded in a direction of advance of the seeder, a seed box on said support, a plurality of seed tubes on said support distributing seed from said seed box, a plurality of sowing blades engageable in said ground and each connected to one of said seed tubes for sowing seed distributed to the respective blade by the respective seed tube, means for pivotally mounting each of said sowing blades tailwheel fashion on said support for swiveling about a respective substantially vertical swivel axis, and means for imparting side to side movement to said axes transverse to said direction, said method comprising the steps of:
- (a) displacing said support substantially linearly in said direction;
- and
- (b) while said support is displaced substantially linearly in said direction imparting said side to side movement to said swivel axes transverse to said direction so that each of said sowing blades is moved in an undulating pattern and seed is delivered in said pattern and adjacent the respective pattern from each blade as said support is displaced over said ground in said direction.
A method of sowing seed, comprising the steps of:
- substantially linearly displacing a seeder over ground to be seeded in a direction;
- engaging respective swivelable sowing blades on said seeder in the ground;
- feeding seed from a common seed box to said sowing blades;
- and
- imparting side to side displacement to swivel axes of each of said blades as said seeder in substantially linearly displaced over said ground, thereby moving each of said sowing blades in an undulating pattern and delivering seed in said pattern and adjacent the respective pattern from each blade as said support is displaced over said ground in said direction .
