Seed planting apparatus
First Claim
1. Planting apparatus comprising, in combination:
- frame means, furrow-opening means attached to said frame means, first and second arm units, each arm unit being independently pivotally mounted to said frame means for providing forwardly and rearwardly disposed end portions, a gauge wheel rotatably carried on the forward end portion of each of said arm u nits, and articulated means interconnecting the rear end portions of said units with each other so that said gauge wheels are movable relative to each other comprising, in combination;
a butterfly link having a first end and a second end, with the butterfly link being pivotally mounted with respect to the frame means about a pivot axis located intermediate the first and second ends of the butterfly link;
a first link pivotally connected to the first end of the butterfly link and to the rearwardly disposed end portion of the first arm unit; and
a second link pivotally connected to the second end of the butterfly link and to the rearwardly disposed end portion of the second arm unit.

Abstract
The disclosed planting apparatus includes a frame fixedly attached to a transversely extending tool bar. Secured to the tool bar and extending rearwardly therefrom is a platform on which the seed hopper and herbicide container are mounted. Seed from the hopper is dispensed downwardly to a seed metering device which deposits seed at uniformly spaced intervals into a furrow formed by a pair of furrow-opening discs and a shoe associated therewith, the shoe packing or compacting the soil at the bottom of the furrow formed by the discs. Playing an important role in the invention is a walking beam system which mounts a pair of gauge wheels for independent movement relative to each other and also relative to the furrow-opening discs and shoe. Also supported by the walking beam system is a pair of furrow-closing or press wheels, the pitch of which can be adjusted for varying soil conditions. The depth of the furrow is initially selected by positioning a handle which raises and lowers an articulated link assembly that acts against the pair of pivotal arm units on which the gauge wheels are rotatably journaled and also acts against a rearwardly extending arm unit that supports the press wheels at the rear of the apparatus. In this way, unevenness and/or obstacles encountered by either of the gauge wheels will not adversely affect the planting depth that has been selected by positioning the handle relative to a depth-indicating gauge.
