hand gun / spot sprayer. make sure you get something with extra hose.
the hand gun itself. prefer something i can toss on some extensions (cheap plastic extensions), for about 4 to 6 feet length. with an adjustable tip.
--you might consider a 3pt hitch forks, or 3pt hitch carry all. and then getting a "skid version" of a sprayer. so you can re-use forks and what not for other things.
--if you have a FEL (front end loader), just toss something into the bucket if your just spot spraying.
--make sure the primary filter just before pump inlet is easily accessable for checking and cleaning.
--for boom nozzles. see if they come with a little "filter" inside the nozzle. and some sort of mini valve to adjust amount of liquid each nozzle gets.
--look at bottom and see if you can actually drain all the liquid out of them.
--see if there is a "cleaning wand" or "mixer wand" inside the tank. (pipe going through it, with a bunch of holes in it) to make cleaning easier, and/or help mixing chemicals with water better.
--if you have hills, check to see if tank has any sort of "baffles" mini walls inside the tank, to help reduce sloshing of the liquid. if not a smaller tank can help reduce sloshing within reason.
--garden hose, some of them can be "a pain" toss garden hose entire end of hose into tank and hope hose will not fall out as you walk away getting other things ready. there might be a garden hose hookup or "quick connect" that might be easier done.
electrical wise
--see if it comes with a fuse (possibly fuse located at/in the pump itself (standard vehicle fuse most likely))
--dip switch SPST (single pull single through), might be nice mounted at tractor, so you can adjust booms, and then flip switch on/off when turning around and like.
on demand pump, hand gun/spot sprayer w/ extensions, boom nozzles, and primary filter there is not a lot to them. most of it is just did manufacture have there head screwed on correctly when they built it in laying everything out. one of those things is extra hose for the hand gun/spot sprayer, and jacking it around and pulling the hose around, and then coiling hose backup, and uncoiling hose. some are good some are bad. and can leave your hands a mess of chemicals dealing with the hose.
