we have had no cold weather starting problems.  We always plug them in when we need them.  If we work in the winter on job sites they have electirc by that time anyway.

We have 4 277's know and they are awesome!!  Learn how to run them and you will have no track problems and will enjoy every minute in the cab!! 

Only thing that will stop them is the 12' box blade I made to push snow, But that is the size they put on payloaders, so go figure!!
