MARKER SPEED ADJUSMENT
The marker hydraulic system includes two
flow control valves. One flow control valve
controls the lowering speed of both markers
and one controls the raising speed of both
markers. To adjust marker speed, loosen the
jam nut and turn the control(s) clockwise or
IN to slow the travel speed and counter
clockwise or OUT to increase the travel
speed. The flow controls determine the
amount of oil flow restriction through the
valves, therefore determining travel speed of
the markers.
DANGER: The flow controls should be
properly adjusted before the marker
assembly is first put into use. Excessive
travel speed of the markers can be
dangerous and/or damage the marker
assembly.
NOTE: When oil is cold, hydraulics
operate slowly. Make sure all adjustments
are made with warm oil.
NOTE: On a tractor where the oil flow can
not 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.
MARKER ADJUSTMENT
To determine the correct length at which to
set the marker assemblies, multiply the
number of rows by the average row spacing
in inches. This provides the total planting
width. Adjust the marker extension so the
distance from the marker blade to the center
line of the planter is equal to the total
planting width previously obtained. Both the
planter and marker assembly should be
lowered to the ground when measurements
are being taken. The measurement should
be taken from the point where the blade
contacts the ground. Adjust right and left
marker assemblies equally and securely
tighten clamping bolts. An example of
marker length adjustment follows:
Number of rows x Row spacing inches = Dimension between
planter center line and marker blade.
16 Rows x 30" Spacing = 480" Marker Dimension
The marker blade is installed so the concave
side of the blade is outward to throw dirt
away from the grease seals. The spindle
bracket is slotted so the hub and blade can
be angled to throw more or less dirt. To
adjust the hub and spindle, loosen the 1/2"
mounting hardware and move the bracket as
required. Tighten bolts to the specified
torque.
IMPORTANT: A marker blade assembly
that is set at a sharper angle than
necessary will add unnecessary stress to
the complete marker assembly and
shorten the life of bearings and blades.
Set the blade angle only as needed to
leave a clear mark.
A field test is recommended to ensure the
markers are properly adjusted. After the field
test is made, make any minor adjustments
as necessary.
