description A mobile turf instrument apparatus has a wheeled frame that may be propelled over the ground by a motive device, such as by a separate vehicle or by its own engine and drive train. A driven arm is carried on the frame and revolves in circles to periodically insert the probe(s) of a probe assembly into the ground during motion of the frame. The drive to the arm is momentarily disengaged when the probe(s) of the probe assembly are inserted into the ground. The probe assembly comprises two parts that rock relative to one another. Two soil measurement devices are connected to the probe assembly. A soil moisture sensor is coupled to the probe assembly for measuring soil moisture when the probe(s) are inserted into the ground. A load cell is responsive to the amount of rocking of the two parts of the probe assembly to measure soil compaction.
