The '''Weatherly 620''' is a 1970s American agricultural monoplane designed and built as an improved variant of the Weatherly 201 by the Weatherly Aircraft Company of McClellan, California.<ref name="Janes" />
==Design== The Weatherley 620 is an all-metal single-seat low-wing cantilever monoplane with a conventional landing gear with a tailwheel. Examples have been fitted with a Pratt & Whitney R-985 radial engine, and PT6A or TPE331 turboprop engine, driving a three-bladed tractor propeller. In the forward fuselage, the aircraft has a either a 355 US gallon hopper or a 320 US gallon hopper that feeds an agricultural dispersal system. Most pilots that fly the weatherly aircraft, prefer the 320 gallon hopper aircraft. <ref name="Janes" />
==Variants== ;Model 620 :1979 initial production variant. ;Model 620A :1987 production variant with a Pratt & Whitney R-985 radial engine. ;Model 620B :1992 production variant with a Pratt & Whitney R-985 radial engine. ;Model 620TP :1980 turboprop variant with a Pratt & Whitney PT6A-11AG. ;Model 620B-TG :1997 improved turboprop variant to replace the 620TP with a Honeywell TPE331 turboprop.
