Coles County, Illinois | I run a Hardi but there's a lot of good choices out there. I like the Hardi because of the diaphragm pump pretty well eliminates a sprayer controller if you stay in the same gear. Yes replacing broken parts is expensive but maintaining the system is cheap as all fittings have replaceable o-rings.
Some features to consider:
Boom length 3X planter width. (maybe 5 times if you're 6 row narrow).
Calibrated sight tube for partial fills. Visible from tractor while spraying. I have a 650 gallon sprayer. I like to dump full containers of herbicides. So if a package is for 11.5 acres and I'm spraying 15 gallons per acre then I need to add 517.5 gallons for 3 packages and adding 34.5 acres of capacity. I also don't need to run the system completely empty.
Cruizer II instead of foam marker. Get a guidance unit that paints the applied area and is controlled by the boom being on. This allows one to double check that the rate is correct. If I started a field with 450 gallons @ 15 gallons/acre and the Cruizer II says I've sprayed 20 acres, I should have 150 gallons in the tank.
Ball shutoff valves.
Chemical inductor with volume indicator. Better mixing of chemicals and mine has a ring in it to rinse the walls with spray solution When adding AMS I can just dump a bag into the inductor. The ring keeps the AMS flowing into the system. The volume indicator is nice for bulk chemicals.
