High Wheel Sprayer Built From Old Tractor
 ✖  |
Old tractors can be easily converted into big-wheel flotation sprayers that glide right over bumps, holes, and center pivot irrigation tracks without any boom bounce or frame damage, according to Nebraska farmer J.J. Granstrom. He built a 300-gal. sprayer equipped with a 35-ft. boom out of the rear end of a 1950's vintage International M tractor.
Granstrom stripped the tractor down to the rear axle and wheels, leaving the seat mounting deck in place. He bolted the 300-gal. tank and tank mounting frame from his old sprayer lengthwise on top of the deck. He bolted sprayer's boom onto an angle iron framework that bolts onto the base of the drawbar and to the axle.
"It really rides smooth. The big tires cause less bounce when going over our center pivot irrigation tracks," says Granstrom, of Holstein. "Our old conventional sprayer was equipped with 14-in. tires and the frame kept breaking on center pivot tracks. Whenever we went over a track the ends of the booms would fly 3 or 4 ft. up in the air. The smoother ride lets this rig do a lot better job of spraying. The wheels follow in the same tracks as the tractor tires which reduces soil compaction.
"The boom covers ten 36-in. rows. If we ever want to switch to 30-in. rows we can move the wheels in just like we would on a tractor. A 500-gal. tank could be used for more capacity."
The boom can be adjusted vertically by loosening two bolts.
