I have a 14 year old Toro 2450 2 stroke that has served me well. It's aged well (better than me) but struggles with anything over 6-8". A 15 incher really taxed the thrower and myself earlier this year. We got the job done but it took a while. The paddles and bar took a beating from running plunges (both hard on the machine and me) and need replacing. I generally go out and do several removals before it gets too deep when possible. Nightime snow blew that option this time. I live in Denver and most of our snow falls are 2 to 6 inches with several 6"+ plus a season and then the occasional big one 15-18" with drifts. Most tend to be on the heavy wet side as well. I was thinking of getting a small (cheaper) 24" two stage (craftsman or troy-bilt) to handle the occasional deeper stuff and keep the Toro hoping it won't poop out any time soon for the little stuff. The other option is a more powerful single stage like a Toro 821 QZE (or even a Toro 721E?) and sell or give away my small Toro. Anything I get will have to have electric start. I'm in a dilema on which way to go. I'd like to make a decision soon to take advantage of any summer sales. I'd prefer to only have one machine but will accomodate two if necessary. I know a more powerful single stage will handle the smaller stuff and take a bigger bite in deeper snow than my current machine, I just don't kow how big of a bite. I also know a 2 stage is overkill for the 2 inchers but shines in deeper snow. I'd appreciate any advise or recommendations as I might be overlooking something. PS I'm 72 and not getting younger or stronger and have a 26 x 28 driveway and 180 feet of corner lot sidewalk to clear. Thanks!
