I am looking at a Lesco 50 gal. sprayer with 300' hose, electric reel, 4 hp kawasaki, and 6.5 gpm/275 psi pump. It is not the ideal rig, but I can't justify the extra cost for the bigger tank/pump combinations. Does anyone have any experience with this sprayer, and if so how has it worked out? Will this pump give me the efficiency I need to spray average 8-12k ft. residential yards? Thanks in advance for any input.
