Rotary cutters (bush hogs) are PTO-driven brush decks. Fit is hitch class, minimum PTO shaft horsepower, PTO RPM, and rear lift — not the tractor’s marketing engine rating.

Sub-compacts fail on Limited Category I geometry and lift before engine HP looks wrong. Five-foot and wider decks also need frame weight and ballast discipline. If Fit says Partial, look up PTO HP on the OEM sheet — we never invent shaft ratings.
Scan curated cutter classes below for hitch list, min PTO, and weight. Open the Attachment Fit checker with your tractor, or jump to a type Fit page for an example machine. Finish with serial-year OEM manuals.
