DEPTH CONTROL DEVICE FOR PLANTER

摘要

A depth adjustment for an agricultural seed planting implement has a depth control assembly of side by side gauge wheels pivotally mounted to a frame with leading equal length arms in a staggered relation. A settable lever acts on the arms through a control rocker having arms with the same staggered relation to control soil flow.

1. An agricultural seed planting implement, comprising:
a frame moveable in an up and down direction relative to soil area over which the frame traverses; a seed trench opening assembly mounted to said frame; a pair of gauge wheels; equal length gauge wheel arms pivotally mounted to said frame for journaling said gauge wheels, the position of the gauge wheels setting the depth of the seed trench; a depth control device including a control lever settable in a plurality of discrete positions and a control rocker pivotally connected to said control lever for abutting said gauge wheel arms to set the depth of said seed trench; and, wherein said gauge wheel arms are mounted to said frame in staggered locations and said control rocker has arms staggered to matched the staggered locations of the gauge wheel arms.
