| Note | Operator selectable coverage: 0.2 - 0.8 L/mu00b2 (4 kph - 40 kph) / 0.05 - 0.2 gal/ftu00b2 (3 mph - 25 mph). Coverage rates above 0.6 L/mu00b2 may not be available at higher speeds depending on head count and configuration. |
| Note (1) | Spray head opening is automatically controlled by the system to achieve Auto Mode Coverage or manual mode flow rate. |
| Note (2) | The Auto Mode setting controls water coverage and automatically adjusts to the number of spray heads being used u2014 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) | Alternatively, manual mode allows the operator to set a water flow rate that is constant regardless of ground speed. This mode is not recommended for daily operation and will reduce watering efficiency and may increase fuel usage. |
| 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. |
