I popped around to the small airfield here and spotted this crop sprayer sitting on the field. I've done some research since then. It's a 1994 Grumman Ag-Cat powered by a 9 cylinder Pratt and Whitney R-1340 600 horsepower (450 Kw) radial power plant.

Nice set Roger, I'm kinda surprised it's only from 1994 I would have guessed it was older.

Thanks, Ryan. The company was sold to Allied in 2001, after which only a handful were built new. They now concentrate on doing factory rebuilds as the demand is so high.

The reason bi-planes are so popular in the agricultural arena is the fact that double the wing area equals double the lift. The stall speed for the Ag-Cat is 64 mph (104 Kph).

Wow, I knew the stall speed would be low on a bi-plane but never would have guessed that low. Heck my pitching arm was way faster than that back in the day.

Nice! Would be pretty cool to see some shots of it flying around, spitting its spray about.

I'll be in discussion with the owner over the winter, Don. The planes are pretty much put away since the spraying season is over for the year.

Great machine Don. Be good to take that for a spin. Definately want a low stall speed operating that close to the ground.
