Bray you probably was towed by a Piper Pawnee, an airplane I haven't flown in years and I don't know of any operator that uses them anymore. We have the much larger and turboprop powered (750 & 1,100 shp) Air Tractor AT-502s and AT-602s with GPS swathing and guidance systems. The 260 hp Pawnee would be straining with 150 gallons in the hopper where we'll carry 500 and 600 gallons with the 502s and 602s, which is why most all of the Pawnees are retired to towing banners and gliders.
It's been years but I remember the Pawnee being a kick in the pants, as long as it wasn't carrying a load.
