Self-Propelled Mini Sprayer For Greenhouses And High Tunnels
“With more and more hoop houses going up for growing vegetables, we decided we needed to build a sprayer for them or someone else would,” says Benuel Iva.
The self-propelled SP-50 has a 50-gal. capacity. A 22-ft. boom is standard. However, booms are usually custom ordered to match the grower’s needs.
“We custom-build every sprayer to fit the greenhouse,” says Iva. “It’s easy to switch booms. Wings fasten with a single bolt, and the center section can be removed with 4 bolts.”
The drive unit is a 13 hp. Honda with hydrostatic, single wheel drive. A single lever controls forward, reverse and speed control with a maximum speed of 6 mph. The JB 9 gpm, 3-piston, diaphragm pump sprays at 280 psi.
The unique design of the SP-50, with its 60-in. length and 60-in. wheelbase left to right, resembles a motor scooter with a tall outrigger. It allows the operator, power unit, and tank to travel down one row space while the outrigger wheel travels down a neighboring row space.
“It has an 80-in. axle clearance, which allows it to straddle 72-in. tomato stakes,” explains Iva. “A 96-in. winch raises and lowers the boom to match crop height.”
The SP-50 is priced at $9,750. The lower cost alternative for walk-behind tractor owners is the BCS Compatible Sprayer. It starts at $3,500. Its 55-gal. spray tank feeds a Hypro XL 6 roller pump that can be driven off the pto. Options include a separate JB diaphragm engine pump drive. Both systems will produce 250 psi. An alternative 12-volt pump will provide 50 to 120 psi.
Booms are available up to 20 ft. wide or 12 ft. to either side. The trailing sprayer has an adjustable hitch for use with most makes and models of walk-behinds. It includes a seat for the operator and can tow a 36 by 60-in. optional dump trailer. A winch- operated 90-in. boom lift kit is available for spraying sweet corn and other high crops.
