CAUTION!
Avoid pressure when using the quick-fill attachment. The rubber
plugs installed in the manifold may be forced out under pres-
sure.
Marker Operation
Markers can be raised simultaneously but can only be low-
ered one at a time. If both markers are required down at
the same time, run one marker down, momentarily start to
raise it, reverse the hydraulic lever and lower the opposite
marker. Holding the lever down then will force both mark-
ers down.
On a tractor where the oil flow cannot be controlled, the
rate of flow of oil from the tractor may be greater than the
rate at which the marker cylinder can accept it. The tractor
hydraulic control lever will have to be held until the cylinder
reaches the end of its stroke. This occurs most often on
tractors with an open-center hydraulic system.
On tractors with a closed-center hydraulic system, the
tractor’s hydraulic flow control can be set so the tractor’s
detent will function properly.
Transporting
!
CAUTION!
Never transport the planter faster than 20 miles per hour !
Before transporting the planter, check and practice the fol-
lowing items:
• The planter can be transported with full hoppers of
seed. It is best NOT to because the extra weight in-
creases the chances for problems on the road.
• Check that the gauge-wheel tires are properly inflated
as listed on the Tire Inflation Chart, “Appendix” on
page
52.
• Comply with all federal, state and local safety laws
when traveling on public roads.
• Remember, the planter is wider than the tractor and
extreme care must be taken to allow for safe clear-
ance.
• Make sure the safety chain is properly attached with
enough slack in the chain to permit turning.
• Always transport the marker with it folded in the flat
fold position.
