Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi everybody, this is my first post, I've been a lurker for a few years, and I finally have a legitimate question.... Back in 2008 I bought a new Ariens 924DLE. At the time I had a gravel driveway, and unless we got over 6" of snow I didnt bother using the snowblower, since it was better to just pack the snow into the gravel by driving over it and get  a nice "base" of snow, so the next time we got a storm I wouldnt constantly throw rocks when using the snowblower. This year we just had the driveway paved, and I plan on using the snowblower alot more. We have quite a large driveway, its really more like a parking lot...lol... the top section is about 53W' x 45'L , the center section is 70'L x 30' wide and the bottom section by the road is 45' w x 10' L... I estimated about 5700 sq. ft.... Now, I should have bought a bigger machine when I bought the 924, but I didnt, now I want to upgrade and am wondering what my best bet is.. I really like the 28" pro due to the 420cc engine size, giving me the ability to clean out the EOD without missing a beat, but would the 30" platinum be more worthwile with being 2" bigger but only using the 342cc engine....I cant go any larger than 30" due to my sidewalks, so the PRO32 is out. Thanks for any help
