Single Marker Speed Adjustment
The single marker hydraulic system is equipped with a
needle valve to control how fast the marker operates. The
needle valve is located in the hydraulic hose line at the rod
end of the marker cylinder as shown in Figure 3-21. Turn
the adjustment knob clockwise to slow the speed down
and counterclockwise to speed it up. Adjustments should
be made for safe operating speeds at the tractors operat-
ing RPM. Excessive folding speed could damage the
marker and may void the warranty.

Transport Carrier
When the marker is folded, the 2nd section should be cen-
tered in the transport carrier saddle and lay parallel with
the top of the drill box. To adjust the front to rear position of
the storage saddle, loosen the 1/2" x 6" u-bolts (#1) which
fasten the transport carrier mount to the box frame and
slide the transport carrier assembly forward or backward
as needed. To adjust the height of the transport carrier
saddle, loosen the 1/2" x 2" u-bolts (#2) which hold the car-
rier tube to the mounting bracket and slide the carrier tube
up or down as needed. Figure 3-22 illustrates these two
adjustments.
