A seed conveyor assembly that delivers seed to a planting surface in a controlled manner to maintain seed placement accuracy within a trench. In one embodiment, a seed guide for a seed conveyor assembly includes a relief portion and an introduction portion that includes at least one protrusion. The protrusion is angled from a side of the introduction portion toward the center of the introduction portion. The end of the protrusion is proximate the center of the introduction portion being further from the relief portion.

A power seeder may include a frame, one or more wheels, one or more blades capable of cutting into soil, an engine capable of powering the one or more blades, and a seed hopper. The seed hopper may have an opening capable of dispensing seed located forward of the one or more blades. The one or more blades may rotate in an opposite direction to a forward rotation of the one or more wheels. In some embodiments, the seeder may further include a handle for adjusting the height of the one or more blades, a plurality of interlocking teeth, and a spring. The spring may provide a load to counteract the force of gravity on the one or more blades. The aerator may also include a flap located between the opening and the one or more blades.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

Wheat or other granular, flowable material is supplied from a metering hopper at a controlled rate through a limiting aperture at a base of a hopper side wall. A moving surface which has served as a floor of the hopper emerges through the aperture, carrying a covering of material out and toward a material disposal area and is then recirculated into the hopper. The moving surface is a repeatedly used upper surface of a disc or cone that is rotated by a motor. Supply of material is immediately varied by varying the speed of the moving surface.

An agricultural sowing implement that, when moved by a drive unit, distributes seeds in the ground with regular, uniform spacing. The agricultural sowing implement comprises a rocker system placed behind the chassis of the implement where a seed dispenser is positioned. The rocker system may include a beam connected to two depth-limiting wheels on the ends of the beam. In one embodiment of the disclosure, provision is made for two interlinked smaller wheels connected to a central lower extension of the beam, the set of wheels being encircled by a rolling band. In addition, provision is made for two dampers, one for each of the depth-limiting wheels.
