True, but it really depends on the weight and depth of the snow. A smaller tractor, like the OP's 4100, isn't going to push much snow, even with MFWD and chains. With the storm we got yesterday, a blower is the only method, unless one get's out multiple times during the storm...and the drive way is going to get narrower and narrower each time he plows.
Like you, I have both a front blade and rear blower...and many (what I call nuisance) snows, the blade is quite adequate...but it wasn't for the storm we just got

I'd rather have a front blower, but to add one to my 4052 would cost >$10K unless I was lucky enough to find a good deal on a used one. No mid-PTO, so I'd have to go with a rear PTO driven, or preferably, a hydraulic driven blower.
