You didn't state weather you're flying a turbine drom or a piston drom, or the model (A, or B), or what your experience level is...or the type of flying you'll be doing with the airplane.
Ag work isn't entry level work. The Dromader is a fairly forgiving airplane, but in turbulence in mountainous terrain it can become quite demanding, and can be quite unstable. In normal flying conditions it's a comfortable, stable airplane, but not in rough conditions close to the hills.
If this is your first ag job, you'd be much better served getting a season or two in a pawnee or an ag truck, or an air tractor. Getting a few passes before the season begins and then going to work isn't well advised. People have done it for many years, but today we understand that there are better ways. The dismal fatality rate of the old days has been changed thanks to todays thinking, training, and practices.
All my Dromader time has been in turbine airplanes, and the powerplant changes the character of the airplane considerably. The pratt version vs. the garrett version are very different, as is the way the straight dromader differs from the A or B. The nuts and bolts are essentially the same, but the airplanes do fly differently.
