2SBD30 30-Foot, Folding, Soybean Machine 173-086M
Press Wheels and planters plugging a. Drilling in damp or wet conditions may increase this problem.
b. DO NOT back up machine in field, or stop and allow machine to roll
backwards with openers in the ground.
Gauge Wheel leans to left or right a. Realign brackets where gauge wheel is attached to main frame by
adjusting the mounting bolts.
b. Check to see if gauge wheel axle bearing are securely attached to
gauge wheel arm.
Improper folding of drills a. Adjust post frame adjusting links Figure 3-7 in
"Section 3" on page 14.
b. Check hydraulic system for air and oil leaks.
c. Clean out small orifice fittings in wing cylinders.
d. Make sure that the wing boxes unfold and are aligned, see “Sec-
tion 3 Pull Bar Adjustments”, on page 14.
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 can crack fittings and plug
hydraulic lines. JIC and O-ring fittings do not require sealant. 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.
Raising and lowering machine is rough a. Lubricate lower rollers of vertical transport tubes and uneven locat-
ed between the transport tires.
b. Check hydraulic fittings for leaks.
c. Rephasing cylinders not properly bled. See “Section 3 Hydrau-
lics” on page 11. When raising machine at end of field the lifting
cylinders should be fully extended to insure that they are always
rephased.
