GENERAL INFORMATION
Yetter Drill Markers were designed to operate on grain drills and planters from 14 feet to 35 feet wide. For
non-folding grain drills from 14 to 22 feet wide, bi-fold markers are used.
All Yetter Markers are hydraulically actuated. A sequence valve is provided to alternate automatically from
left to right marker. After each raise cycle the valve switches hydraulic oil flow to the opposite marker.
Yetter markers were designed for hydraulic systems providing up to 2500 psi hydraulic pressure. For
hydraulic systems that have variable flow control, this control may be used to adjust marker speed. It may
be necessary to provide restrictors in the lines to reduce marker speed with some tractors.
MOUNTING KIT INSTALLATION
On Great Plains, M & W, Marliss, Tye, IH5200/5400 and JD 750/1560, assemble mounting brackets to front
of drill frame as shown using hardware provided in the mounting kit for your particular type of drill. See
appropriate drawing and parts list.
MARKER INSTALLATION
Mount marker base to mounting brackets using 1/2 x 1-3/4” cap screws, lock washers and nuts. Two sets
of holes are provided in the marker base toward the outer end of the drill. Use the hole set that allows
clearance of obstruction on the frame for your particular implement.
NOTE: If drill is equipped with a grass seeder attachment, it may be necessary to install a marker
extension kit.
