Overview
A hobby homesteader walks through a real operational puzzle on his TYM 4820: why pushing the grapple joystick fully open caused the jaws to close instead. The video explains the practical difference between a true third-function valve and a diverter valve, then traces the specific culprit, the tractor's built-in hydraulic dump feature. Useful for new grapple owners or anyone confused by unexpected diverter-valve behavior.
