Abstract:
1. A mobile turf measurement apparatus, which comprises: (a) a frame propelled over the ground by a motive device other than a walking operator; (b) a probe assembly movably carried on the frame such that the probe assembly has repeating cycles of motion relative to the frame as the frame is propelled over the ground, wherein the probe assembly is lowered on the frame and moves towards the ground and is raised on the frame and moves away from the ground during each cycle of motion; (c) at least one probe carried on the probe assembly with the probe(s) being inserted into the ground as the probe assembly moves towards the ground and being extracted from the ground as the probe assembly moves away from the ground such that the probe(s) are inserted into the ground for a time interval lasting over only a portion of each cycle of motion of the probe assembly; and (d) a soil measurement device operatively connected to the probe(s) of the probe assembly for measuring a parameter of the soil during the time interval when the probe(s) have been inserted into the ground.
