Pelton, Kaplan, and Francis turbines are designed for non-compressible fluids (aka water not air). While they will certainly spin, they would be very inefficient and not what you are after. You will want to use a pneumatic motor or exhaust turbine like Dave Tweed recommended in the comments. Read the last paragraph of the function section for reference:
Pneumatic is generally not a good way to transfer power. Most farm implements use PTO mechanical rotation or hydraulic power. Hydraulics have many benefits over pneumatic; efficiency, noise, power to weight and more reliable in dirty environments. The only benefits of pneumatics that I see are no return loop plumbing and less risk of oil contaminating product (still some risk as most pneumatic systems need oil). I would even consider generating electrical power off the PTO and using electric motors before considering pneumatic.
