Abstract

A depth control mechanism for an agricultural seed planter is made up of an index plate, a T-handle, a spring, and a gauge wheel arm. The T-handle is moved into different positions which are indicated in the index plate. The spring and the gauge wheel arm allow for selective manual movement and locking of the depth adjustment.
