When I WAS a beet grower I was using 2 GATORs to band spray 1100-1200a of beets 4-5x a season.  4gpa 65 gallon tank in the gator & pulling a 12-24 spray boom.   Watch your breezes & try to turn into the wind & you won't get as much drift on you. Sprayed  a lot of insecticide in the tank mixes. Good operator could adv 2 loads hr @ 17a a load.

 DO NOT use a briggs & scrap iron engine. Honda's would last 4-5 yrs, briggs VANGAURDS would be SHOT in 1 yr. Used a 6 roller pump, had to plumb them backwards to use the "cheaper" pumps. In was out & out was in, because the reduction was turning the wrong way.

 Do not miss those days.  Dought if I'll be raising beets again due to a coop that went bad
