i've used 2 sprayers. 1 is a 300 gallon 25 foot boom sprayer that i rent from the grain company. the other is a 15 gallon 12 volt electric sprayer with a 10' boom that i fabricated myself. it is placed in a tow behind cart. right now, i'm trying to make a cradle to hold the 15 gallon sprayer in the 3pt hitch. it sprays 1 gpm and has a 11' swath. when i drive 3 mph i can cover 1.0 acre in 15.0 minutes.
