Self-Propelled Sprayer Replaces Pull Type SPRAYING New Sprayers 18-5-25 "I wouln't part with it unless I could get the parts to build another one right away," says Robert Strasburger of the versatile self-propelled 3-wheeled spot sprayer he built last winter.
At speeds of up to 7 mph, it worked great all summer for cleaning up weeds in corn and soybeans, as well as along fence rows, says Strasburger, of West Lafayette, Ind.
"Our farm is spread out quite a ways and sometimes, if you've got a bad weed patch, it's impractical to take your tractor and pull-type sprayer 20 or 30 miles to get them," he explains.
This way, Strasburger simply loads his sprayer on a trailer and zaps the weeds with a lot less hassle.
The heart of Strasburger's sprayer is the 18 hp engine and hydrostatic drive out of an old Case 446 lawn tractor he bought from a neighbor. The 2-speed transmission chain-drives the two rear wheels.
Strasburger made the 12-ft. long triangular frame out of 2 by 4-in. steel tubing. It supports the lawn tractor motor in front, a driver's seat and battery in the middle and a 110-gal. tank on back.
The sprayer's single front wheel is a Deere planter gauge wheel Strasburger found at a salvage yard. Likewise, the two rear wheels, which are set for Strasburger's 15- in. soybean and 30-in. corn rows, also came off a Deere planter.
Strasburger made a 30 ft.-boom for the rig out of 1 1/4 in.-square tubing and fitted it with a hydraulic height adjustment. A hydraulic cylinder with 8-in. stroke al-lows him to adjust boom height from 20 in. to 52 in. off the ground. That allows him to spray a variety of weeds at virtu-ally any stage of crop development.
In addition to the spray boom, Strasburger also made a 30 ft.-weed wiper, which is steadied on each end by a pair of bicycle tires. That's for treating dogbane, his problem weed, in soybeans.
For added versatility, the sprayer has a hand nozzle for spot spraying fence lines.
