I am fortunate (perhaps also stupid - I vacillate) to have all 3 choices: loader, front blade and front blower. Lately, with the little snow we've been getting, I've kept thinking that I shouldn't have gotten the blower (which I did primarily because I had an Ariens Yard tractor with blade and blower that kept going for 26 years and worked just fine) and just stuck with the FEL and blade. Then we get a storm like this one (which used to be more frequent). I have a 300' driveway and started out yesterday to plow about 12" with the blade, which normally should have been little problem. Didn't get very far; that stuff was heavy (twice the water content of normal, I'm told) and I couldn't make reliable headway. Given that I've a steep downhill part to the driveway, I definitely didn't want to get stuck there, which even with loaded rear tires and 4WD is always a possibility with this much heavy snow, especially when you consider the huge pile likely to be at the bootom from the town plow. So I switched to the blower and went riipping through the snow. Now, would the loader have worked? Undoubtedly. Would it have been as quick? Undoubtedly not.
With a lesser amount of snow and a frozen driveway (mine is crushed shale), the blade is by far the quickest (and my preferred choice), as you can go almost full tilt back and forth and be done in little time (how I love that hydraulic angling!). With a non-frozen driveway, everything takes longer and I hate to have to use the blower then as it doesn't have skid shoes and is much more prone to redistributing my driveway all over the terrain.
Is the blower cost-effective? That's what I keep asking myself, but it sure is nice when you need it. Should we start getting winters again where it really snow, I imagine I'll keep congratulating myself on the choice.
