The Westaby manure application operation in Iowa has grown
along with the hog industry in the state, using application
equipment from the main-line manufacturers and doing some
innovating of its own with custom-designed injectors. The
equipment line-up at the Westaby operation includes Cat
Challenger tractors, triple-axle Mack trucks with flotation
tires, a GMC triple-axle truck with flotation tires, J-Star tanks
and custom built vacuum tanks. The equipment uses custom designed
injector toolbars designed by Jesse Westaby. Everything is measured in feet, and
operators know how far they have to
travel to achieve a certain application
rate. All the rigs are equipped with
Calc-An-Acre measuring systems, to
determine application rates. The average size of a customer haul for
Westaby is now 750,000 gallons. Kevin
Westaby points out, however, that they
still have good customers for whom
they haul 100,000 gallons.
