No you cant let it sit last year we plowed more in March & April then we did all year. as far as the season we go Nov 1st to April 31st 6 month is are contract time but we are garateed 10 plowings all extra are charge extra.
My contracts run from Nov 1 thru March. This year I was still doing fall clean-up in mid November. It seems the leaves fell late this year. I usually have my cleanups finished the first week in Nov. and have all of my properties marked with stakes and snow fences up by the second week.
