Row crop cultivator

A depth control for a towable cultivator having a frame and a plurality of tools mounted on the frame, comprising:

• a gauge wheel means mounted on said frame forwardly of said tools for regulating the depth of penetration into the soil of said tools;
• said gauge wheel means including a gauge wheel rotatably mounted to a gauge wheel assembly and a gauge wheel adjustment arm extending between said gauge wheel assembly and said frame, said gauge wheel adjustment arm pivotably mounted intermediate its length about a substantially horizontal axis to said frame;
• and
• gauge wheel adjustment means associated with said frame for controlling the elevation of said gauge wheel relative to said frame, said gauge wheel adjustment means including a plurality of vertically spaced depth adjustment holes extending through said frame and a substantially horizontal adjustment pin member selectively positioned through one of said holes such that an upper portion of said gauge wheel adjustment arm contacts said pin member so as to limit pivotal movement of said gauge wheel adjustment arm and thereby maintains said gauge wheel at a selected elevation relative to said frame.

A row crop cultivator comprising:

• a frame attachable for towing to a mobile power source;
• a plurality of earth-working tools dependingly mounted from said frame;
• a gauge wheel assembly pivotally mounted to said frame and including a gauge wheel projecting forwardly of said frame;
• and
• gauge wheel adjustment means on said frame for controlling the pivotal movement of said assembly and the elevation of said gauge wheel relative to the frame and thereby regulating the depth of penetration of said tools into the soil,
• said frame comprising a pair of parallel, substantially vertical plates and said gauge wheel assembly comprises a pair of elongated arms, said arms being pivotally mounted at a point intermediate their length between said plates,
• said adjustment means comprising a series of vertically spaced adjustment holes formed in each of said plates and in registry with each other, and a pin member selectively positionable in any pair of said holes so that the upper portion of said arms contacts said pin to limit pivotal movement of said arms.
