The standard answer is generally 5 PTO HP per foot of cutter width; so a 6' rotary cutter would match your 31 PTO HP pretty well. The dealer can probably also make a recommendation. It also somewhat depends on what you'll be cutting. Mowing heavier/ thicker vegetation will require a smaller cutter; Mowing lighter vegetation a bigger cutter could be used.
So using this method, my 2516 Shuttle(with 21.5 pto hp) should handle a 4ft brush hog just fine...I hope. Can anyone steer me to a particular well built brand?
