Claim:
A line marker, which comprises: (a) a frame supported for rolling over the ground by a plurality of wheels, the frame having first and second ends; (b) a spray nozzle carried on the frame for spraying a marking material downwardly to mark a line on a horizontal surface as the frame rolls over the ground, wherein the spray nozzle is carried on the frame in a first spray position closer to the first end of the frame than to the second end of the frame; (c) wherein the spray nozzle is carried on an outrigger arm that is pivotally connected to the frame, the outrigger arm supporting the spray nozzle adjacent one side of the frame; (d) wherein the outrigger arm on the frame is configured to be maintained on the frame during operation of the line marker in a pivotal position selected by the operator, and wherein the operator can selectively pivot the outrigger arm up and down relative to the frame to place the arm in different pivotal positions to thereby increase or decrease the height of the spray nozzle above a reference horizontal plane; and (e) wherein the outrigger arm carries a vertically adjustable rod thereon, wherein the frame has a stop for engagement with a lower end of the rod, and wherein the operator can selectively pivot the outrigger arm into different pivotal positions on the frame by drawing the lower end of the rod inwardly towards the outrigger arm or by extending the lower end of the rod outwardly from the outrigger arm.
