The North Star works. The boomless sprayer runs out a few feet from the middle of the tank and sprays a minimum of a 15 ft width. It has a switch control that runs up to the front of your atv and you can turn it on and off without even going to the tank.

We bought a used big plastic tank tank that holds about 300 gals, or more of water, with a hose out of the bottom, which we load on any truck and fill it up and it follows us to the fields and refills the spreader tanks. That way the sprayers can be filled many times without anyone having to go back for water. The used tanks normally cost less than $50 and will last a lifetime. I bought one for $25
Spraying green fields to kill grass or to spread fertilizer with this set up is a no brainer, So So simple. Just remember to wash the tank out and wash the hoses out at the end of the day and it will give you your money back many times over.
