Need some advise. Looking for a nice 3 point sprayer to put behind a compact tractor. Will be primarily spraying larger properties (2 to 3 acres) and athletic fields. Thinking about a 50 gallon setup?? Fimco seems cheap, but are they ok? I've also looked at Crop Care sprayers. They seem nice. What type roller pump should I look at? Will be spraying organics and broadleaf control. (yes, I'm licensed) Thanks.
