How does the A Frame center pivot get ripped out?
Ever wonder how the center pivot gets torn out of a plow? When a plow is straight and you hit something, the cushion valve or crossover valve allows the plow to "absorb" the hit. When the plow is fully angled, there is no give, and the pivot point is changed to the end of the PA Ram. First the hole eggs out (repeated hits), and then eventually if left unchecked, rips out. A maniac can rip it apart in one solid hit going too fast.
