Field Operations
This section presumes that all pre-operation check
have been made on both air cart and drill, and cart is
loaded with seed and any treatments.
Single Hopper Operation
There are two ways to disable a meter if only one
hopper is being used.
1.
For short planting sessions, simply set the variable
rate gearbox control arm to zero (0). The input shaft
to the gearbox still rotates, but the output shaft
does not, and no material is metered.
2.
For extended planting sessions, loosen the idler
and remove the gearbox input drive chain. This
minimizes wear on the gearbox.
Fan Speed
Fan speed is monitored and reported by the seed
monitor, but is manually controlled. The optimum rate
depends on the seed type, any treatments. “Fan Speed
Adjustment” on page 68 for further information.
Refer to Figure 64
ADC2350/E only: Fan shut-off valve must be open for fan
to operate. This valve is not present on ADC2350B/BE.
Equipment Damage Risk:
Always engage the fan with the tractor at a low engine speed.
Engaging the fan when the tractor is at high speed may cause
fan damage.
Do not reverse hydraulic flow with the fan running.
