Simple New Paper Strip Field Marker
"Paper is much cheaper and the marker itself is cheaper because there are no pumps or reservoirs to buy," Marshall told FARM SHOW.
The paper marker consists of a control unit in the cab, a 12-V DC timer, a paper roll holder turned by a small electric motor, and a solenoid-operated knife that slices off lengths of paper at timed intervals. The timing interval is set, depending on conditions ù such as the height of the crop and wind conditions. Once set, it operates automatically through the field. The length of the paper strips dropped at each interval can also be set as desired.
Does the wind blow the strips of paper?
"As the paper spins off the roll, spray from the end nozzles saturates its leading edge. When the paper is cut, the heavy wet end drops to the ground and the lighter end remains visible to the tractor operator on subsequent rounds," explains Marshall.
He notes that, besides being cheaper to buy and operate, the new paper strip marker is easier to set up and operate. "You don't have to mix up dye or foam solutions or maintain a pump," he notes.
The paper, which is available in white or fluorescent orange, comes in 1,500-ft. rolls. The marker comes with wiring for 80 ft. of boom. It retails for $695. Paper costs $5.25 per 1,500-ft. roll.
