A total of 400 of this model were produced.

Super Ag Cat A/450

The G-164A became the main model starting with serial number 401. This model featured a 450 hp (335 kW) Pratt & Whitney R-985 radial engine along with a higher gross weight, increased fuel capacity, larger diameter wheels and improved brakes.

The upper wing was raised on the "B" model by 8 in (20 cm) do reduce aerodynamic interference between the wings and improve cockpit visibility.

Mid-Continent King Cat

This after-market conversion of the Super Ag Cat C/600 replaced the 600 hp (450 kW) Pratt & Whitney R-1340 engine with a Wright R-1820-202A radial engine that produces 1,200 hp (895 kW).
