Combine Crop Sprayer

Combine Crop Sprayer COMBINES Conversions 19-6-29 "It's a great way to make use of an old cornbine," says Donald Jobgen, who built a self-propelled sprayer out of an International 403 combine with variable speed hydrostatic transmission. With the cab positioned directly above the boom, Jobgen says you can't beat the visibility of his home-built rig. And it's al-ways ready to go with no need to mount tanks or other equipment on a tractor. And maybe best of all, it was inexpensive to set up. "I have a large heated shop so I do a lot of building in the winter. I began by strip-ping the combine down to the frame, leaving just the cab, chassis, wheels, engine, and transmission." He remounted the engine crosswise at the back of the frame, and mounted a 325 gal. fiberglass spray tank on the frame between the engine and the cab. There's also a 30-gal. foam marker tank. Booms are 57-ft. wide when fully ex-tended and can be raised and lowered hydraulically, `mounted in place of the feederhouse. Wings fold manually back against the sides of the combine. Jobgen bought the boom from a dealer. "I've used the sprayer three seasons with absolutely no problems. I can spray at 9 miles per hour. The booms and pressure are both regulated electronically from in-side the cab. I also have a monitor in the cab for measuring speed and acres," says Jobgen, who plans to build another self-propelled sprayer this year from a Deere combine.
