Embodiment Construction

[0018] Referring now to the drawings, and in particular FIGS. 1 and 2, there is shown an embodiment of a planter 10 of the present invention. In the illustrated embodiment, the planter 10 takes the form of a row crop planter, but could also take the form of a grain drill or the like. FIGS. 1 and 2 illustrate individual row crop units 12 of a multi-row planter, each of which is substantially identical and connected to a common tool support beam 14 . For simplicity, only a single row crop unit 12 is shown.

[0019] The row crop unit 12 includes a frame 16 connected to a tool support beam 14 by parallel connection means 18 . The tool support beam 14 is connected to a traction unit (not shown), such as an agricultural tractor. For example, the tool support beam 14 may be connected to a farm tractor using a 3-point hitch assembly. The tool support beam 14 may be connected to a transmission wheel assembly, a track marker arm, etc., which may be of conventional design and are not ...

Abstract

An assembly for opening and closing a furrow in soil includes a furrow opener with a pair of discs positioned at an angle relative to each other. The discs each have an inner side facing toward each other and an outer side facing away from each other. Each disc also has a leading edge and a trailing edge relative to a travel direction. A furrow closer includes a pair of wheels, each having an inner side facing toward each other and positioned adjacent to a corresponding disc outer side. Each wheel also has a leading edge positioned between a corresponding disc leading edge and disc trailing edge, and a trailing edge positioned rearward of a corresponding disc trailing edge relative to the travel direction.

Description

technical field [0001] The present invention relates to agricultural machinery, in particular to ditch openers and ditch combiners. Background technique [0002] An agricultural seeder such as a row crop seeder or grain drill places seed at a desired depth within multiple parallel seeding furrows formed in the soil. For row crop seeders, multiple row crop units are typically ground driven using wheels, shafts, sprockets, gearboxes, chains, and the like. Each row crop unit has a frame that is movably connected to the tool support beam. The frame can have main seed box, herbicide box, insecticide box, plow opener / closer, etc. [0003] A plow opener mechanism uses a depth gauge wheel disposed near the leading edge of a single disc opener assembly that includes a seed tube on the rear side of the disc. The wheel provides depth adjustment, cleans the front of the pan and limits soil lifting and throwing around the pan. One or more closing wheels drag the disc to move the soil...
