Pappy- congrats on your purchase, you are gonna love it. I have a Pronovost P-74-INV on a 3720 so similar to your set up. I tried just front chains and it kinda works, Depending on the snow or ice , road surface and temperature. The time it really doesn't is going uphill with the blower raised as that takes most of the weight off the front wheels. I need to try siping for the shoulder seasons but for winter anymore its front and rear euro style chains-just awesome.
As far as ability to clear deeper snow if you can drive through it you can blow it so for me up to about 24in its no big deal. You can deal with the occasional much deeper area by raising the blower and backing in then going forward. I tend to go out fairly often because that limits the packing from other vehicles and its so easy and quick.
Ignore the naysayers and enjoy your blower and report back please.
