Hydraulic Systems
The hydraulic system on 2250 air carts consists of a blower con-
trol circuit, an auger control circuit, and a hydraulic meter drive
control circuit. A combination of various control valves enables
all three circuits to be powered by one hydraulic remote on the
tractor. This system was designed to function under a maximum
hydraulic pressure of 2900 psi.
Air Cart to Drill Hydraulic Couplers
The couplers connecting the air cart to the drill/implement are
(3/4”) #12 ISO 7241 Series B, high-fl ow couplers. Using these
reduces the pressure drop across the coupler and enables the
operator to easily disconnect the air cart from the drill/implement.
It is important to ensure that the pressure line on the tank is con-
nected to the pressure line on the drill.
The blower motor case drain line employs a (5/8”) #10 ISO 7241
Series B coupler. This smaller size ensures that it cannot be
confused with the larger couplers.

Caution
Be sure that the case drain line on the blower motor is not
connected to pressure. Damage to the shaft seal or motor will
result.
