Abstract
A marker assembly has a scalable frame that allows a user to set the width of the frame to provide flexibility in defining the width at which a marking furrow is made. The scalable frame includes multiple linkages interconnected to one another in a manner that allows the frame to be folded into a relatively compact configuration for storage and/or transport. An outer linkage has a telescoping member that allows a user to vary the spacing of a marking disc to vary the width at which a marking furrow is made in the ground.
