Ayres Thrush (aka Snow S-2, Aero Cmder Ag Commander & Rockwell Thrush Commander)

from Wikipedia:
The Ayres Thrush, formerly the Snow S-2, the Aero Commander Ag Commander and the Rockwell Thrush Commander, is an American low-wing agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first example flew 59 years ago. Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered.

The Thrush was designed by Leland Snow and first flew in 1956, and before long was being produced in series as the S-2 by the company he founded, Snow Aeronautical. In 1965, the corporation and all its assets were purchased by the Aero Commander division of Rockwell, which put it into production alongside the CallAir A-9 that it had also acquired, branding both unrelated (though similar) machines as "Ag Commanders". When Rockwell dropped the Aero Commander brand, the S-2 was renamed the "Thrush Commander".

In 1977, Rockwell sold off the production rights to the aircraft and the production facility at Albany, Georgia, which were purchased by Ayres Corporation, a firm which had been built on retro-fitting turboprop engines to Thrush Commanders. On June 30, 2003, Ayres' assets were purchased by Thrush Aircraft, the current producer of the aircraft.
