I'm ready to take on my first implement modification project having gotten to the point where I think I can weld well enough to do something simple.
My box blade is the kind that has a hinged rear blade and I want to set it up so that the rear blade could be fixed optionally. Others have noted that a fixed rear blade works well for final grading... figured I might as well have the option.
There are some box blades that come from the factory so that the rear blade can be adjusted to either be fixed or not. I've never seen one like this. If you have one, can you describe to me what the mechanism is that either locks the blade in place or allows it to move?
I have attached a picture of my box blade. My current thought is to weld a 3/8" plate to each side so that it over hangs by a couple inches off the rear. Then I would drill 2 3/4" holes into each of these side overhangs through which I can insert two 3/4" pins.
The pins alone might do the trick but the rear blade is not shaped exactly straight (unless one 3/4" pin would do it).
Thought was to cut another 3/8 piece for each side which would be loose and would fit up against the rear blade. It would also have two holes to align with the welded on side plate, through which the 3/4" pins would go.
Not sure if one 3/8" piece on each side supported by two 3/4" pins will adequately hold the rear blade in place.
Your thoughts are appreciated.
P.S. Rob - bet you will have some good ideas on this one. You put me up to considering rigging something up to fix the rear blade when necessary
