Nifty Way to Build High-Capacity Sprayer COMBINES Conversions 14-5-9 "When I got the opportunity to buy an old 420 Versatile combine, I considered several different conversion projects and finally decided to make a field sprayer out of it," says Jay Rose, Willow City, N. Dak.
"First I stripped it to the frame. I used the grain tank and unloading auger to make a 4-ton feed hopper that is used in my cattle operation. The other extra parts were sold.
"Then I moved the Chrysler 318 V-8 engine down and back, almost over the rear steering wheels, realigning the variable speed sheaves and drive belts. The next step was to remount the control plat-form just ahead of the engine. All control cables, brake lines, electrical wiring, hydraulic lines, and fuel lines were shortened and reattached.
"A curved 350-gal. poly tank (Summers Mfg. Co., Maddock, N. Dak.) was mounted between the front drive wheels. The water pump for the sprayer has an electromagnetic clutch that runs off the V-8 engine. I modified a 45-ft. pickup spray boom by adding 3 ft. to the center section to clear the combine wheels. I added a platform to stand on when filling the tank.
"I installed a Micro Trak 3000 spray monitor that includes a speedometer, flowmeter servo-valve, pressure gauge, three electric solenoids to control booms, and one solenoid for agitation in the tank. The control panel can be programmed for desired gallons per acre and miles per hour. If mph changes, the monitor compensates pressure and maintains gallons per acre.
"I use an Adja foam marker to prevent misses and overlaps. With 6 exterior lights, I can spray at night to avoid strong daytime winds.
"Four air filters on top of the 12-ft. cab provide fresh air and good visibility. Wheel tracks are much less than a 3/4-ton pickup and the sprayer performs better in soft ground than a 4-WD.
"This is the second season for my home-built sprayer and it's worked very well. It's got all the features of new sprayers on the market but with the added bonus of being self-propelled. Total cost to build was $3,000."
