I ended up with this old sprayer from a guy who sold produce out of his place for years, but had passed away. It has John Deere name on it , a 18 gal tank and the pump is belt driven by a Briggs 3hp motor, I believe the pump is shot. Also has a recoil hose assembly mounted on the front with a brass wand, has a short tongue for pulling with a tractor and has 3 wheels . 1 pivot in the front and 2 8" wheels in the rear. Would like to see if I can get more information on it , like maybe pump output so I can replace the pump with something the Briggs small motor can operate. Any info is appreciated. Checked at the John Deere website, but no luck.
