You're looking at a torque turn (or maybe even an anti-torque turn)
There's plenty published on it. You don't use the pedal (much) but rather increase torque and let the engine turn the machine around the mast. Sometimes known as an Ag Turn.
Most machines can get down OK from 50ft, about the right height for an ag turn...
I have heard of drivers happing a quick power nap in the turn before now.
Maybe someone who has actually sprayed can tell us...
