Waters areas up to two acres without an underground irrigation system
The Underhill Tracker™ T-400 allows you to economically irrigate large areas from 1/4 acre to 2 acres where an underground irrigation system would be too costly or impractical. Ideal for athletic fields, cemeteries or any other large area with a water supply. The Underhill Tracker is completely powered by water to pull itself along a nylon cable and automatically shuts down when it reaches the cable's end. Simply position the unit where you want to begin irrigating and connect to a water supply with a heavy-duty 1" I.D. hose. Unroll and anchor the nylon cable to the end point, set the speed control (which controls the application rate) and turn on the water. Requires at least 9 gpm at 50 psi (flow rate typically available from a 1" or larger pipeline). Larger spray patterns may require up to 15 gpm at 85 psi. Will typically irrigate about 2/3 acre in eight hours. The Tracker can pull up to 360' of hose, allowing for a 400'L maximum irrigation length. Includes a galvanized anchor stake, 360 ft. of nylon cable and 1" brass quick couplers (for hose). 22"H x 33"L x 22"W. 80 lbs. Made in Germany.
