So are the 2 angled nozzles on each side made to spray beginning at the outer tire edge and beyond into crop ? That way you run the tire right at the edge of the field and can spray how much ? into the crop. I like that idea very much.

I made a 60 gallon sprayer set on on a three point carryall frame.

Have 3 options 

Wide broadcast nozzle for yard or gravel area spraying.

Short boom for spraying perimeters boom basically covers tractor tread width.

Hand spray gun on a reel with around 20 ft hose for around buildings and other stuff. Can also fit hand gun with another broadcast nozzle or regular boom nozzle for spraying vertically or wide swaths up and down along fencerows or wooded areas to keep undergrowth back from edges.

May need to add a adjustable rod to the front of tractor and attach nozzle fed by hand gun line to spray edges of fields. Drive tire right at edge of field and nozzle would cover maybe first foot or so into field.
