Overview
A short teardown where Mike pulls a PTO shaft off his brush cutter, separates the male and female halves on camera, and explains grease points (u-joint zerks and the sliding shaft itself) plus the surprise that shaft profiles are not universal, there are roughly 50 shapes, and mismatching front and back halves is a real gotcha. Good quick primer for new implement owners who've never serviced a PTO shaft.
