Walk-Behind Sprayer Is Simple And Lightweight
"It works great for getting into tight areas that are hard to reach with a trailing sprayer behind a garden tractor or ATV."
Cafourek had previously built a walk-behind self-propelled sprayer that was equipped with a 4 hp Briggs & Stratton engine and a 15-gal. poly tank, as well as a 12-volt air compressor and 1-gal. foam tank and foam markers (Vol. 29, No. 4). The engine belt-drove a pair of 8-in. dia. wheels that friction-drove a pair of 26-in. high motorcycle wheels.
His new sprayer is much lighter so it rolls much easier. It rides on a pair of 26-in. high bicycle wheels and is equipped with only a 5-gal. poly tank and a 4-roller HyPro pump.
The rig has a 29-in. boom equipped with floodjet nozzles on each end, resulting in a total spray width of 6 1/2 ft. There's also a flat fan nozzle at one corner so he can spray Roundup in a 14-in. band along fence lines and buildings, reducing the need to use a weed trimmer.
"I use it a lot in cemeteries where I can't get through with my garden tractor sprayer. It works great around shrubs, flowers and gardens," says Cafourek. "The big bicycle wheels make it easy to push around. It weighs just under 100 lbs. loaded. It's light enough that my wife can easily operate it. The boom can be folded up to go through a 29-in. gate."
One of the bicycle wheels friction-drives a 1 1/2-in. dia. wheel that drives the 4-roller HyPro pump. Pulling on a spring-loaded lever at the back of the rig puts tension on the wheel to engage the pump. The lever is connected to a cable that goes around a pulley and down to the wooden wheel. The pump delivers liquid through a hose to the nozzle with bypass agitation.
"It took a lot of trial and error to make everything work right," notes Cafourek.
