I build things using the TLAR School of Engineering method. (That Looks About Right)
With a longer pivot arm, the vertical blade angle will change less as it floats up and down. But your shorter pivot point would still work okay. You could put it close to the bolt holes and be able to put the bolts back in with the pivot pin still in place.
I didn't think about resale value, because it will work so well you won't ever want to sell it!
That makes sense.
I think it should work good. The blade weighs 750lbs but the tractor will be carrying the QA and some weight of the blade so I should be down to 600-650lbs on the skid shoes. I was probably double that with the weight of the loader on it. I know the steering will be better because the tractor handles the blade really well if I hold it up a inch or 2 off the ground.
