TROUBLE SHOOTING (CON’T.)
PROBLEM SOLUTION
9. Press wheel or openers plugging a. Drilling in damp or wet conditions may increase this problem.
b. Openers may be moved from a staggered to an in-line position to
reduce trash thrown from front openers into rear openers.
c. Reduce down pressure on openers.
d. Do not back up drill in the field, or stop and allow drill to roll back-
wards with openers in the ground.
e. If using double "V" press wheels, adjust angle bar.
f. Check Seed-Lok Wheel.
10. Improper folding of drills a. Adjust post frame adjusting links.
b. Check hydraulic system for air and oil leaks.
c. Clean out small orifice fittings in wing cylinders. See page 2-4.
d. Make sure that the wing boxes unfold to a straight line. Check to
see that both pull bars are attached to the boxes at exactly the
same distance inboard from the inboard edge of the drill box {90"}
and both are exactly the same length.
11. Hydraulic adaptors cracking a. JIC fittings do not require high torque.
b. ALWAYS use liquid pipe sealant when adding or replacing pipe
thread hydraulic fittings. Plastic sealant tape can crack fittings and
plug hydraulic lines. JIC and O-Ring fittings
DO NOT
require seal-
ant. O-Ring fittings require a thin coat of oil on the O-Ring.
IMPORTANT: When using sealant on pipe threads, the friction
between the threads is reduced; therefore, be certain not to over-
tighten causing damage to the cylinders, valves or fittings.
12. Feeder cup sprockets locked up or a. Check for foreign matter lodged in one or more feeder cup
twisted feeder drive shaft sprockets.
b. Liquid insecticide from seed has dried within the feed cup. Re-
move the build up by disassembling each feed cup and scrape the
foreign substance from the turning surfaces.
NOTE: Liquid inoculant should be applied with caution and care
should be taken to clean the feeder system after drilling treated
seeds.
13. Raising and lowering drill is rough a. Lubricate lower rollers of vertical transport tubes located between
and uneven the transport tires.
b. Check hydraulic fittings for leaks.
c. Rephasing cylinders not properly bled. See " Tractor Hydraulic
Hook-Up " beginning on page 2-4. When raising drill at end of
field, the lifting cylinders should be fully extended to insure that
they are always rephased. If machine is only raised enough to lift
openers out of the ground, lift cylinders may eventually get out of
sequence and cause uneven seeding depth.
14. Sprocket and chain interference a. Adjust wing box top link on tool bar.
