First time snow blower owner here. I have a separate post on the general forum where I asked basic questions, but I am also interested in model specific info. I recently picked up a Toro CCR2450 and have a few questions: How dependable is this thing? Are there any known issues or failure points that I should address? What kind of mods have you guys made? What is a good source of parts? Any other information that would be helpful? Thanks.
