There are two manufacturers of special purpose Ag Aviation planes in North America, Thrush Aircraft being one of them. The planes are manufactured in Albany Georgia. Yorkton Aircraft Service is the Canadian Authorized Dealer for Thrush . The tour plane is a 510 gallon aircraft, powered by General Electric’s 800 horsepower engine. Thrush Aircraft is on tour creating awareness about the Thrush brand and promoting the theme of Feed the World. Ag Aviation is playing a larger role each year in helping producers protect their crop to produce quality grains, oil and cereals that become the groceries we need! The tour started with an open house at Yorkton Aircraft Service at the Yorkton Regional Airport Saturday, and this week the plane will be touring Manitoba and Alberta with stops in Saskatchewan as well.
