Maintenance
7-8 December 2016 CX 8105 - Ground Drive
Caution
Care should be taken when working near
the air cart while the fan is running. Product
blowing out of the system could cause
personal injury.
Note: Extended life can be obtained if the hoses
are rotated 1/4 turn once a year.
Air Delivery System
General
The air delivery system of all air carts is extremely
important for the proper metering of product to the
openers. The metering system on all pressurized air
carts is sensitive to air leaks. Loss of tank air pressure
could affect feed rates, which could become erratic
or even stop.
• Regularly check that all hoses are free from kinks
or blockages throughout the day. To check for
blockages raise seeding tool out of the ground and
with the fan running turn crank a couple of turns.
Equal amounts of material should be deposited under
each boot. If not, check the following for blockage:
1. Seed openers and secondary hoses.
2. Divider heads by removing access doors.
3. Primary hoses and collectors.
4. Metering wheels for damage to the flutes of the
wheel.
• Keep fan inlet screen clear and free from debris.
• Place a plastic bag over the fan when the unit is not
in use. This helps prevent moisture from entering
the system.
• Check periodically and at the end of each season
for air leaks at hose connections.
• Check periodically and at the end of each season
for air leaks in the following areas:
1. Tank lid seals.
2. Metering body shaft seals.
3. Metering body to tank seals.
4. Collector to metering body seals.
5. Fan to plenum.
6. Plenum to collector.
7. Inspection doors, for leaks and loss of seal
memory.
8. Collector door seals.
9. Couplers between air cart and seeding tool.
10. Access doors on divider heads.
Note: There must not be any air leaks from the tank.
This air leakage causes air turbulence in the
tank which can result in inaccurate metering
rates.
• Once a year check for wear of primary and secondary
hoses.
