Press Wheels and planters plugging a. Drilling in damp or wet conditions may increase this problem.
b. DO NOT back up drill in field, or stop and allow drill to roll back-
wards 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.
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 caus-
ing damage to the cylinders, valves, or fittings.
Hydraulic Marker functioning improp-
erly a. Check all hose fittings and connections for air & oil leaks.
b. The chain on the folding 3-Section marker should be slack when
the marker is both fully extended and fully raised.
c. Check tractor hydraulic oil level.
d. Check all bolts and fasteners.
e. Open needle valve, if provided. Cycle markers slowly and reset
needle valve if plugged.
Drill is not pulling level (parallel to
ground, front to rear) a. Readjust 3-point top link to level drill.
b. If using pull-package equipped with a sliding top link, increase
opener spring pressure in order to rock drill forward.
