ABSTRACT:
A latch mechanism is provided for locking the front furrow wheel of a plow when the plow frame is in its lowered plowing position. The latch mechanism is inoperative when the plow frame is raised to its transport position, thus permitting the castered furrow wheel support to freely rotate about the vertical spindle pivot axis. A latch is pivoted to the upper end of the vertical spindle about a horizontal axis and has a downwardly extending finger adapted to drop into a recess in a flat ramp on the upper link of a parallel lift linkage for the castered furrow wheel.
