Bud,
Nice set-up, I have a 4310 and I had a chance to buy that same blade used but like brand new, the guy mounted it once and decided it was to much work to switch to FEL, I was thinking about cutting and welding the rear mounts to the fel mount posts to speed up the change over to the loader, I think the front mount could stay in place with the loader on. The only problem is the rear mounts hang down, greatly reducing ground clearance, also you couldn't do my plan and use your MMM at the same time, you would still have to remove the loader mounts.
The pictures don't do it justice, looks kinda dainty, but I've seen one close up and I know that thing is built like a dozer blade. It does have down pressure, right? Will it lift the front wheels off the ground?
I didn't buy it cause I didn't think it would be a huge advantage over just the loader in the snow, is it? I do think it would be the ultimate tool for working in the woods, drive way or road work, or any type of grading and leveling and would have bought it in a second if I had an imediate need for it.
Good luck! John,
P.S. I like the mirror and will do the same. And that grubbin bucket looks like you could dig a nice drainage or utility trench since it's narrower than the wheels, though how would you dump the spoil? Guess you could back up till you cleared the trench.
