Self-Propelled Sprayer Looks Factory-Built
"We've used it to spray 6,500 acres of small grains and peas, from burn-down through desiccation, and it has performed flawlessly. It's a relaxing machine to run, too," says Pierre Delorme who, along with his father Leo, last year built a big self-propelled 4-WD sprayer that covers more ground than the Melroe Spra Coupe they used before.
"We equipped our home-built sprayer with a 550-gal. tank and an 88-ft. self-leveling boom so we can cover in one pass an en-tire round planted with our 44-ft. air drill," says the Sylvania, Sask., grain and cattle farmer. "Top speed is 10 mph, compared with 14 mph with the Spra Coupe. However, the larger boom allows us to cover a quarter section in an hour and a-half, compared with two and a-half hours before with the Spra Coupe's 56-ft. boom."
The Delormes used the frame and axles from a 6-WD Army truck. They power their sprayer with a 300 cu. in. 6-cyl. engine out of a Ford pickup. It's coupled to a four and five speed manual truck transmission which provides a total of 20 forward and five re-verse speeds.
They equipped the sprayer with the power steering unit off a junked White combine and mounted a cab from a 6650 Hesston haybine on front of the unit.
"We found four 42-in. rims that came off a Hi-Boy sprayer at our local fertilizer and chemical dealer," Delorme notes. "The centers were cracked so we cut them down to match four 38-in. tires we bought at an auction sale. We reworked the centers to fit the Army truck axles.
"It has a high volume centrifugal pump with electric shut-offs for the boom, which can be raised from 18 to 65 in. off the ground. The whole right and/or left sections of the boom fold back on spring-loaded breakaways, as does the outer 3-ft. end section.
"We equipped the sprayer with a 50-gal. rinse tank that we can use to rinse the chemical tank and boom on-the-go with controls inside the cab. We built a foam marker system for the sprayer using an old water heater as a 20-gal. holding tank. We also installed night driving lights and a belly pan and crop dividers. The sprayer was sandblasted and painted by our brother, Raymond, who does body and fender work."
Out-of-pocket expense was about $7,000.
