Eric,
Here is a thread that might be helpful:
Help
The thread deals with wrestling with a brush hog rather that a boxblade, but the technique is the same.
Here is a copy of my post on detaching the implement:
<font color="blue">"Actually, removing the brush hog should be a snap, require little, if any muscle most of the time, and impress your neighbor.
First, remove the PTO shaft, as described in an earlier post. Collapse the shaft and let it rest on the front edge of the deck.
Second, remove the toplink pin. When the brush hog is sitting at rest, there is a "sweet spot" in the length of the toplink where there is no pressure on the pin. Usually, you are very close to being there when the unit is sitting flat on the ground. However, the toplink can be too long or too short for the purpose of easily removing the pin. For example, when lowering the brush hog to the ground, if the tailwheel touches down much before the front of the deck, the toplink is too long, ie pushing on it's attachment point. If the toplink is short, the front of the deck will touch ground before the tailwheel and be pulling as the tailwheel comes to the ground. Does that make sense? So, the toplink may need to be lengthened or shortened a bit to remove the pin easily. As you approach the "sweet spot", turning the adjustment rod gets easier, and you can actually see the toplink pin shift a little from front to back (while lengthening) or back to front (shortening) as you reach the "sweet spot". No sweat. Now you've got the toplink undone. By the way, my use of "too long" and "too short" only applies to removing the toplink pin, and not to proper toplink adjustment for use of the implement when cutting.
Next, is the part that's hardest for most folks, but is really easiest of all...removing the lift arms from the implement lift pins. For this part you may need a little WD40, but little else. You will let physics work for you and really impress your neighbor. TRACTOR PHYSICS 101- When backing, the 3PH lift arms want to spread apart and come off of the lift pins. The opposite is also true. When mounting the implement...driving forward wants to bring the lft arms closer together, ie they'll slide onto the lift pins. That's a topic for another day. Lower the 3PH all the way down. Then, spray a little WD40 on the lift arm balls and lift pins. If there is a rubber/bungee cord connecting the two lift arms, remove it temporarily. Pull the lynch pins. Back the tractor an inch at a time (With my hydrostat trannie, I do this while standing beside the tractor), and the lift arms will slide right off (no hammer, no kicks, no muss, no fuss), easy as can be...very impressive to female neighbors.
I'm sorry this post is so long, but this 3PH mount/dismount thing requires some explanation to make it the simple chore it should be. A little practice, a little finesse, and you'll be a pro.
Good luck with your neighbor's tractor! "</font>
