Air Power 2 fan system
Enhanced air seeding performance would not be possible without the updates to the 15,152.8-L (430-bu) and 19,381.5-L (550-bu) 1910 and C850 Air Carts. For the wider seeding width, more fan capacity has been added.
Air Power 2 provides two independently controlled fans – one for seed and one for fertilizer. Along with large, 76.2-mm (3-in.) primaries, more accurate delivery rates are possible across the full width of the seeding tool, from opener to opener. Plus, Air Power 2 allows growers to deliver high rates under field operating conditions – up to 40 percent more product delivery per primary compared to the single-fan system.
Dual fans are required for tow-between and tow-behind carts on the 23.2-m (76-ft) 1870 and 18.3-m (60-ft) 1895 models along with the eight primaries. Each fan will direct air to one set of primaries. Two selective control valves (SCVs) are required for the fans. The fan speed will be controlled through the SCV flow control.
Air Power 2 will also be compatible with the current 17.1-m (56-ft) and 23.2m (76-ft) 1870 Air Hoe Drills, as well as the 13.1-m (43-ft) and 18.3-m (60-ft) 1895 Disk Drills, plus the 15.2-m (50-ft) and 18.3-m (60-ft) 1890 models. An option is available for stainless-steel primaries to resist corrosion from high fertilizer rates.
C850 Air Cart
There is a slide at the meter to choose bottom or top shoot for each meter. There is also a valve on the tank pressure system to choose top or bottom shoot. This same valve is used to adjust the amount of air to the tank to create the proper pressure differential.
Tank pressure valve
The arrow on the valve handle should be pointing to the top of the range for the top shoot and the bottom of the range for the bottom shoot. If the tank will not be in use, set the pressure valve to the middle setting to not pressurize the tank. The operator should use the gauge to find the correct setting. An electronic pressure sensor will send a warning to the display if the tank pressure differential is out of range.
If pressure is in the green operating range, the tanks are sealed and operating correctly. The electronic pressure sensor is located behind the mechanical gauge on the side of the cart.
