I just noticed the recent addition to my original post.
I got through the winter, including the 30" March blizzard we had, using my rear mount Woods SS74. It took a while but my stiff neck is finally gone. I appreciate all the advice and info provided in this thread. A PTO hydro powered front blower looks to be too costly to construct but I like the idea of a self powered unit. The only question is, if I fabricate the rig myself, how much HP would be required to spin a 74" blower in deep snow?
BoylermanCT makes a good point about the cost of buying a ready made self powered blower or building one myself. For the same $$ I might be able to get a smaller used tractor with a front mount blower.
I learned something this past winter that actually made me rethink the front blower issue. I mainly use it to blow back the snow piles along the side of the road when they get too high. When that happens, I can't push the snow over them with my pickup plow and the road narrows. During the March blizzard, my friend from across the valley came over with his
L3830 to help. He has a 90" FEL mounted front blade which was much more task efficient. I was surprised at how high he was able to pile snow! Working at a 45 degree angle to the road, he pushed back the banks almost twice as fast as the blower moved them. The section he did looked pretty ratty buy hey, it got the road open!
I can get a FEL blade for <2k (I already have a 3rd function kit) and with the 74" blower on the rear, I'd have a pretty good working solution. I may just go that route.
