Abstract
A depth gauge (30) is connected to a vibratory plow (10) for indicating the depth of a blade (13). The depth gauge (30) has a rod (31) pivotally connected to the housing (11). The rod (31) has a first end (31a), a second intermediate ground following portion (31b) and a second end (31c). An indicator bar (36) has its first end (36a) connected to the second end (31c) of the rod (31). A depth indicator (50) is provided. The second end of the rod (31c) is restrained for a general vertical movement proximate the depth indicator (50), wherein as the housing (11) is raised or lowered, the ground following portion (31b) stays in contact with the ground and results in pivotal movement of the rod (31) and thereby a vertical displacement of the indicator bar (36), thereby providing a depth gauge.
