I have a long driveway on a steep hill, it is 14 to 16 degrees of slope or 24-26% slope.
In my area we get a lot of very wet heavy snow, this type will pack down into ice easily when driven over.
I have tried to plow and or blow snow while traveling uphill. All that will do is wear out your equipment faster, use more fuel and cause more breakage and down time.
Using the Euro patterned studded tire chains traction is not an issue. I can drive through 12" or more with no problem.
A couple of times we have gotten 36" or more in a single dump. When we get that much it is usually a lighter flufflyer snow which is not hard to drive through.
I have used trucks and plows, tractors with plows mounted on the FEL, tractors with rear mounted back blades, tractors with a pull type blower, tractor with the rear blower that you back up using.
My favorite is the back blade, pulling it while driving forward for 90% of the time. Then spinning the blade around and using it in reverse for the last 10%. Hydraulic angle on the blade is a big help as I cast the snow to different directions in different areas of the driveway. This is because depending on were you are in the driveway one side is a bank and the other is a drop off.
Normally I will pull down the drive to the first curve, reverse and just back right up in the path I just cleared, at the top move over drop the back blade and start my next pass down when I reach the area were I left my blades pile and backed through it I'll drop the loader bucket and shove that pile over the drop off, then raise the bucket and rear blade and repeat. I work my driveway in 4 sections that way.
When I have bladed at least one time and the driveway has stayed frozen so no large rocks have freed themselves I may switch to the inverted blower. I run it in much the same way all though at times I will run the length of the driveway, then turn and dead head back up and drive down blowing again. When I get to the bottom the first time, I stop blowing and pull out turn around and and pull ahead a few short runs to clear out the driveway opening to the road. I also often back up a hundred feet or so on the road and clear the snow off the road so the plow trucks don't make a plow wipe in the end of the driveway.
There are a multitude of options available, it all depends on what you can and will spend. Front blades mounted directly to a tractor which work very well. Front blades mounted on the FEL's which have not impressed me much at all. Rear blades pulled or pushed which work fairly well for me. Rear blowers facing rearward which will do a good job. Inverted blowers used while driving forward, which are handy and work well.
You can get larger tractors with front 3 points and pto's which would be able to use the "conventional" rear mount blower on the front as a forward driven blower which would be very handy I expect. You can get front mounted blowers that are powered by a driveshaft powered by the rear pto to the front. There are also front mounted blowers with there own power plants to run the blower, in my mind most are way under powered to work well unless they are extremely large heavy and powerful.
Now this if it had a front pto or the rear to front pto drive would make a snow eating beast;
