I'd also take a hard look at the company providing service. If one is lucky enough to get a Sears machine that is trouble-free, it would be the luck of the draw. Beware of Sears field service operations and their technicians. I'm currently going through some unbelievable problems with them as I've described on another thread.
Remember this is a seasonal machine used on demand and Sears will not prioritize according to your seasonal needs. Sears will only give priority to refrigeration that contains medicine. I'm touched. There are many appliance dealers who will respond immediately to broken refridgerators, etc.
It's snowing hard, your machine won't work, you call Sears and they will make an appointment anywhere between ten days and two weeks! When the tech arrives and, if your lucky, he'll discover the problem but needs a part. He'll order the part, you'll receive it in ten days or so, and he'll eventually visit to install depending on his busy schedule. After the fix, you hope it works. If not, the lengthy cycle begins and behold, it's Springtime after many snowstorms.
I explained to the Sears helpdesk that many senior citizens have bought snowblowers for obvious reasons. Too many tragedies over the years with people over 50 & 60 dropping dead of heart attacks from snow shoveling.
Once out of warranty, I plan to deal with a local shop who I trust will be responsive.
