P&W R1340
500 SHP @ 2250 RPM
HOPPER 1514 L

The durability, safety, flying ease and proven heritage of the AT-401B makes it the choice of operators looking for an affordable upgrade to a high capacity, low maintenance piston engine ag plane. Here is an aircraft with an impressive combination of performance and features that help operators cover more acres at less cost.
 
At the heart of the AT-401B's economy is its ultra-powerful Pratt & Whitney R1340 radial piston engine. Widely regarded as one of finest radial engines ever produced, the R1340 has been remanufactured to Air Tractor specifications for improved performance, economy and reduced maintenance.
 
Like all Air Tractor models, the AT-401B provides superb visibility, a stall resistant wing design, and more than ample power that's balanced by clean aerodynamics to provide speed and maneuverability even at maximum payloads.
 
The AT-401B makes a great partner for a growing business. From its large 400-gallon hopper that helps cut ferry time, to its Hoerner wingtips which improve the rate of climb and overall control. The AT-401B delivers unsurpassed value -- economically, efficiently and productively.
