Hydraulic powered 60 ft high clearance sprayer SPRAYING Miscellaneous 15-2-10 When Albert Harder, Butterfield, Minn., needed a new high-clearance sprayer, he couldn't find what he wanted on the market. So he decided to build his own - a hydraulic-powered, articulated steering sprayer equipped with a 60-ft. long boom and full-size tractor tires.
Harder's sprayer is equipped with two 250-gal. tanks in front. A 4-cylinder Deere diesel engine provides power to two hydraulic pumps, eight hydraulic cylinders, and four orbit motors. Each orbit motor powers a wheel. The sprayer's frame can be adjusted on-the-go from 90 to 106 in. wide, allowing use in rows from 30 to 40 in. wide. The boom can be raised from 3 to 6 ft. off the ground and tilted from side to side for use on hillsides.
"I've used it for 13 years now and have sprayed over 60,000 acres with it. It paid for itself long ago," says Harder, who operates his own farm and also custom sprays. "I use it mainly to spray 2,4-D with drop nozzles in tall corn and also to spray Basagran in soybeans. My sprayer pivots in the middle like a big 4-WD tractor so it turns short, and the rear wheels follow the front wheels so I don't drive over much corn while turning. The four big, equal-sized tires make for a smooth, stable ride and let me go just about any-where, even in muddy conditions. If I want I can raise the boom higher than 6 ft. by loosening four bolts."
One of the sprayer's hydraulic pumps powers the orbit motors while the other pump powers the hydraulic cylinders. Two cylinders are used for steering with one cylinder located on each side of the hinge point. The boom is equipped with four hydraulic cylinders - one cylinder raises and lowers the boom, one tilts it up and down, and one on each side folds the sides back against sprayer for transport.
Harder salvaged four rear wheels from a Minneapolis Moline tractor and installed new tires on them.
