DRILL MAINTENANCE
Proper servicing and adjustment is the key to the long life of any farm
implement. With careful and systematic inspection of your grain drill, you can
avoid costly maintenance, time and repair.
1) After using your drill for several hours check all bolts to be sure they are
tight. Refer to torque values chart in your operator’s manual.
2) Lubricate all chains with chain lube.
3) Check for the proper air pressure in the cart tires: 28 psi in the 21.5 Lx 16.1SL
4) Check all chain idlers for proper adjustment. Check that each idler is taking up
excess chain slack. DO NOT OVER TIGHTEN CHAINS. Adjust until the pull
side of chain has no more than a ¼ inch of movement from the centerline of the
pull.
5) Re-pack the wheel bearings annually.
6) Grease the gearbox shaft bearings every 50 hours.
7) Grease the jack shaft bearings and clutch shaft bearings every 10 hours.
NOTE: Always refer to your owners manual.
ADJUSTMENT BEFORE GOING TO THE FIELD
1) Hitching drill to the tractor.
A) Attach the tractor to the cart. The air cart frame should be level front to
back. Relocate hitch clevis if required on the cart.
B) The hydraulic hose ends are color-coded. A single tie of a particular
color is for cylinder extension and the fan motor. Two ties of a
particular color are for cylinder retraction.

NOTE: The fan circuit hose with one yellow tie is a ½ inch hose, and the
hose with two yellow ties is 3/8 inch.

C) When attaching the sump return line, make sure that the quick coupler
is the over-sized connector supplied with the cart. This tip is designed
to reduce the backpressure on the fan circuit as the oil returns into the
tractors hydraulic reservoir. Refer to your tractor operator’s manual for
the proper fan return location. Having too much restriction on return
oil can cause the fan seals to fail and the implement wing down
pressure to not work correctly.
2) Install the monitor control box in a convenient location in the tractor cab.
A) Attach the black lead to the battery ground and the red lead to the +12v
DC power. This power lead is
for both the clutch and monitor
box. On the power lead there is
two identical wire connectors.
One goes to the clutch, and the
other goes to the monitor
control box. The monitor box
and clutch box must both be
plugged separately into the
power lead, if not damage will
occur to the monitor box.
B) Connect the 12-pin connector
lead to the cart harness, leaving
enough slack for turning and
secure any excess wire.
NOTE: The Vansco monitor settings are stored in non-volatile memory,
which means that if power is disconnected, the information is retained.
3) Check the drive system on the cart for the correct sprockets for the
implement being used. The three locations that are affected are:
A) The main transfer shaft. (the shaft under the clutch shaft)
B) The clutch (the sprocket bolt on the electrical clutch)
C) The gearbox out put shaft.
4) When setting a seed rate, there are two places that require a driver and a
driven sprocket. One is the quick-change sprocket on the gearbox to
metering box, and the second set is the meter box gears on the opposite side
of the quick-change sprockets. When installing these sprockets and gears,
always check for the correct placement of the driver and driven location.

a.) Refer to the charts to find the proper sprocket orientation, gear set and
gearbox speed for your desired seeding rate.
b.) Adjust the quick-change sprocket, meter box gears, and shift the two
gear handles to the letter and number on the indicator plate. Always
disengage the gearbox clutch before shifting to prevent damage to the
gearbox.
c.) Place several bushels of seed in the grain box.
d.) Open the REAR calibration door.
NOTE: Do not open the front door unless clean-out is desired.
e.) Place the calibration bag under the meter box.
f.) Place the hand crank onto the gearbox sprocket shaft and turn crank at
approximately 2 seconds per revolution. (If this speed is not held, the
seeding rate will be different than desired) Turn seed handle clockwise.
On units with five towers turn the hand crank 66 ¾ revs. For an
implement that uses four towers, turn the hand crank 83 ¼ revs.
g.) Weigh the calibration bag with seed and subtract the weight of the
empty container to find the seeding rate.
5) Engage the hydraulic lever that runs the fan into detent, run fan for 15
minutes to warm the oil, then adjust the hydraulic oil flow until desired fan
speed (RPM) on the monitor is in the range for seed type. Increase fan speed
for heavier seeding rates, and lower for lighter seeding rates. Use enough air
to move the seed with out plugging the seed tubes for lack of air. Cracking
or bouncing the seed out of the trench is caused by excessive air. Do not
exceed 5000 rpm on the fan speed.

a.) With the fan running, take the hand crank and turn the meter box, as
this will place seed into the tubes. Go back behind the openers and
check for seed under the disc openers. This will find any plugged hose
or openers.
b.) Check for any leaks around the lid by placing flour or talc around the
lid before turning on the fan. If the flour moves, adjust the lid handle
latch.
6.) For monitor set-up, refer to the monitor owner's manual.
FIELD ADJUSTMENT
1.) Check that the in-cab clutch rocker switch is on.
2.) Turn the monitor on.
3.) Engage the hydraulic lever for the fan. Start at a low rpm.
4.) Engage the hydraulic lever that controls the down pressure for the CTA only.
5.) Lower the implement, as the tractor is moving forward.
6) Adjust the implement.
