Note
Operator selectable coverage: 0.2-0.8 L/m² (4 kph - 40 kph) / 0.05-0.2 gal/ft² (3 mph - 25 mph). Coverage rates above 0.6 L/m² may not be available at higher speeds depending on head count and configuration.
Note (1)
Opening is automatically controlled by the system to achieve AutoMode Coverage or Manual Mode Flow Rate.
Note (2)
AutoMode Spray controls water coverage automatically to the number of heads being used and ground speed achieved.
Note (3)
Manual Mode allows the operator to set a water flow rate that is constant regardless of ground speed.
Note (4)
Spray Heads on competitive water distribution systems require tools and maintenance to change flow and spray pattern. Caterpillar is the only company to have variable active spray heads to regulate water spray.
Note (5)
Water flow is continually adjusted during operation to conserve water and achieve desired coverage and flow rate
