摘要： 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.

摘要： A turf injector includes a plurality of slitting knives followed by a plurality of nozzles for injecting chemicals into the ground. Each slitting knife is reversible to bring one of two longitudinally extending cutting edges into use, thereby extending the life of the knife. In addition, each slitting knife has dual sets of mounting holes received on a set of fixed mounting pins to further adjust the vertical position of each knife on the frame. This allows for wear of the cutting edge of the blade and further extends the life of the blade. The hole and pin mounting system desirably mounts each knife with its cutting edge held at a 15.degree. angle of inclination relative to the horizontal to minimize disruption of the turf and the length of the knife.

摘要： A sand trap contouring attachment for a sand trap maintenance machine. A preferred attachment (12) includes a plow blade (30), a pair of blade supports (32) wherein the plow blade (30) is operatively attached to the supports (32) and wherein the supports (32) are pivotally attached to the sand trap maintenance machine (10) frame (18) at pivot points (38). Blade (30) lies at the front of machine (10), pivot point (38) lies at the rear of machine (10), and support arms (32) lie intermediate the blade (30) and pivot points (38). Control member (34) is operatively attached to the supports (32) via links (42) and (44). Control member (34) comprises an operator handle wherein the handle provides an operator gripping surface area right and left of a longitudinal center line of the machine (10). Spring means (36), (37), (39) are operatively connected to the machine (10) and the support arms (32) for biasing the supports (32) and blade (30) away from the ground. Control member (34) is adjustable to two positions. Links (40) and (44) are provided for supporting arms (32) and blade (30) in a transport mode.

摘要： An apparatus and method is disclcosed for cultivating soil and turf by utilization of pressurized liquid injected into the soil and turf. A roller assembly (33) is provided for applying mechanical pressure to the turf after cultivation. Further, a means for setting a first speed in a transport mode and a second speed in a cultivating mode is provided. The apparatus is designed to be bidirectional to allow the apparatus to be used in both a forward and reverse direction. The flow of the pressurized liquid is controlled to be at intervals of from about 0.010 to 0.065 seconds and at pressures from about 2,300 psi to about 5,500 psi through nozzles having diameters of from about 0.033 to about 0.090 inches. The apparatus (10) utilizes a water hammer effect to effect the flow of pressurized liquid out of the nozzles 55 and has found a relationship in the pressure and pounds per square inch of the cross-sectional area of the bore of the manifold to the accumulated area of the output ports of the nozzles.

摘要： A reel type mower (2) has a rotatable cutting reel (4) and a cooperating bedknife (8). A control system (30) automatically positions the bedknife (8) relative to the cutting reel (4). An electrical potential is normally maintained between the bedknife (8) and reel (4). The control system (30) monitors this electrical potential and counts the number of times the electrical potential disappears during a predetermined time interval. If the counted value is different from the reference value, an actuator (32) turns an adjustment shaft (42) to change the position of bedknife (8) relative to reel (4).
