That YMM45 has had some significant modifications. I see that the gauge wheels are moved from the outboard position to inside the rear wheels. Also, the front pto clutch has been moved behind the front bumper, which is why the hood had to be lifted slightly in the front. I noticed that all of the sheilds have been removed from the deck. Make sure that your co-hort, and you also, don't get fingers or anything else in there. The tension is pretty good, and you could really get hurt.
That gearbox move from the tiller to the blower is a neat trick. With all the neat work the previous owner did, I'm surprised he didn't put the snow blower up front. The clutch is already there...
