Sprayer Fitted With Double Booms, Tanks

Sprayer Fitted with Double Booms, Tanks SPRAYING Miscellaneous 16-6-9 Saskatchewan farmer Garry Nerbas had a problem with wild oats in his grain fields, but he didn't want to spray a wild oats herbicide across the entire field because of the expense. He solved the problem by building a sprayer that has two tanks, two pumps, and two sets of 88-ft. booms, allowing him to broadcast herbicides with one boom and spot spray with the other. The sprayer has an 850-gal. tank mounted in front and a 400-gal. tank, carried by 18 by 24 combine tires salvaged from an old International 914 pull-type combine. "When I get to a patch of wild oats, I shut off the broadcast boom and turn on the spot spray boom," says Nerbas. "I can spray with both booms at the same time, but most of the time I don't carry herbicides that are compatible with each other. Each tank is operated by a centrifugal pump, one hydraulic driven and one pto driven. The booms are equipped with hydraulically activated disc markers connected by cables to a cylinder mounted on the sprayer frame. I built the markers by mounting disc blades on a spindle. The spray booms automatically fold back. "I pull the sprayer with a dual-wheel tractor. With big combine tires on the sprayer and duals on the tractor there's very little soil compaction, even though I'm hauling 1,250 gal. The combine tires follow directly behind the outside tires. The booms are supported by four car tires." Nerbas used 2 by 6-in. steel tubing to build a frame for the spray tanks and put a stairway on the side for access to the back tank. He spent a total of $9,000 to put the sprayer together. Contact: FARM SHOW Followup, Garry Nerbas, Box 426, Langenburg, Sask. Canada SOA 2A0 (ph 306 743-2836).
