Who needs a clutch, gears or hydraulics? Its 1903 and the pto stops when I get tired, maybe the shearpins will break before my arm does?
If I can get the rpm up at 540, everything should run fine! Need to invest in one of those new fangled overrunning gizmos cept I heared they are powered by black majik an the devil!
Shearpins/bolts tend to break frequently when the rpm is too low and inertia is unable to overcome the force. However brush mowers have pivoting blades that are supposed to move when it hits something hard so they can maintain the inertia.
If running at the rated rpm and still breaking pins it is likely something is getting hooked that is strong enough to stop the blades (couple of strands of tensile fensing will do it) or the mower is not immediately being disengaged when something hard is hit (can not hear it or do not notice it).
