I got my SCUT primarily for the snowblower, plus the TLB set-up for working some of the trees around into firewood, plus drainage ditches, landscaping, etc....
I also found a good price on a very little-used MMM, and finally tried it, even with some steep slopes on my lawn. It worked great! It saved me MORE time over mowing with a push mower than the front-mount blower did over the walk-behind blower I'd been using. The cut is beautiful, and I found the tractor, with MMM, was easily able to negotiate the slopes.
So, for the first time in this guy's lifetime, I have a rider mower, plus I still have the backhoe & FEL. Very happy. So far I haven't been into the woods very much, so the turf tires may be a problem down the road-- but so far, so good.
Removing implements has not been a problem, either; takes a bit of practice, but doesn't take much time. Summer, most of the time has the MMM only; winter, the BH and the blower. FEL as needed.
A very good all-around machine, IMO. (Granted, my lawn's not that big; a ZTR would be overkill for me.)
