Markers
Hydraulic markers are available. The units have a cast hub,
tapered roller bearings and a bolt-on blade to leave a mark
for you to follow on the next field pass. Each marker requires
a hydraulic circuit for operation. A sequence valve is avail-
able so markers can be operated on the same hydraulic cir-
cuit.
For information on how to operate the markers, refer to Mark-
er Operation, “Operating Instructions,” page 12. For infor-
mation on transporting the markers, refer to Transporting,
“Operating Instructions” page 13. For information on how
to adjust the markers, refer to Marker Adjustments, “Adjust-
ment,” page 19. For information on maintaining the markers,
refer to Lubrication, “Maintenance and Lubrication,” page
27.
