Locate the hose inlet on the backside of the Tracker

2

, see Figure 5-1.  Notice the supplied brass hose 

quick-connect.  Thread the male end of your 1” hose into the threaded female end of the brass quick 

connect.  Underhill offers a wide variety of UltraMax

TM

 1” hoses in both standard and custom lengths.  

See the 

www.underhill.us

 “UltraMax Hose Series” for more information. 

 

Depending on your water source, more hose maybe needed depending on the area to be 

irrigated.

Place the Tracker

2

 at the end of the area to be irrigated and nearest the water supply.  Consider the 

radius of the impact sprinkler and delivery pressure to determine the Tracker’s final position particularly 

considering prevailing winds.  

 

5.

 

Layout the hose parallel to the travel direction of the Tracker, see Figure 5-2 below.  Now make the 

hose connection to your water supply.  Verify the hose is free of dirt, debris and sand by flushing the 

hose from the water supply prior to connecting into the Tracker.

Locate the cable drum nut and trip pin on the side of the Tracker, see Figure 6-1.  Pulling outward on 

the brass locknut and trip pin.  Once released, spool out as much pull cable as needed for the area to be 

irrigated.  Pull the cable slowly so that it doesn’t unravel too quickly.
