Note
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)
Net Power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, muffler, and alternator with engine speed at 1,750 rpm.
Note (2)
The Auto Mode setting controls water coverage and automatically adjusts to the number of spray heads being used — independent of ground speed. This is an exclusive feature designed into the Cat WDS software to help water more efficiently. Water flow is continually adjusted during operation to conserve water and achieve desired coverage and flow rate.
Note (3)
When the truck speed drops below 4.8 kph (3 mph), the system shuts off automatically to prevent overwatering, and then automatically re-starts as speed increases.
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)
Cannon performance depends on nozzle orifice and pipe size. Cannon mode may only be operated manually. Not available for autonomous operation.
