Back on topic...
If I remember correctly, the claim is that one of the pins holding the box blade to one of the lower link arms broke.
edit: from post #63: "Some details on what happened. Neighbor was box blading gravel driveway. Left side pin on box blade failed, was connected properly ( I don't know the details). Box blade tripped and flipped up jamming top link and right lift arm. Neighbor stated it about threw him out of the seat when it happened."
This caused the box,blade to shift away from the side that the pin broke on, obviously moving backwards away from the tractor.
I'm having trouble seeing how that would cause the other lower link on the other side to violently raise upwards, if the tractor was moving in the forward direction.
I can see how that would happen if the tractor was moving backwards… I think I can see it anyway.
But moving forward, something isn't registering. Did this event happen when the operator was pushing backwards with the box blade?
Sorry for the simple question, but I obviously must've missed something… I would really like to understand what happened to cause this damage.
I mean what I need to understand, is why the lift arm actually went up and caused the housing to break, if the tractor was moving forward.
It just seems like if the box blade broke free from one side and that side was back furthest from the tractor and digging into the ground, that it would cause the lower arm to go down rather than up. If the tractor was moving forward.
What am I missing?
