I just measured 22" from tip to center of pivot, hoping to give you some scale for comparison. I suspect you could move dirt to the sides with your tooth better than I could push or pull with mine. Thinking I'd want it moved to the side when approaching a root perpendicular to it. That squared back is only 8" wide. Y'know, the more I compare our two the more impressed I am with yours, esp that QA bit. :thumbsup:
I doubt that our machines are much different, esp since you have the stronger MF CB 65 BH option. (Compact T5C will drive thru' a 4' wide gate) You have more hp & weight & I a tad more reach/depth, but IMO our machines can't be much different in o'all digging ability. (Case/IH 1.1L DX26 is similar size but lighter, too)
btw, I commend you for a TOPICALLY RELEVANT THREAD TITLE that means folks can actually find it for future reference. (Sure beats something like "Finally started it!" or similar near-miss) Man, have you considered building and selling a few more?? :scratchchin:
