We have 6 cords of madrone in our wood room, with another 2 cords on pallets outside. We heat solely with wood and burn about 5 cords. I'll start falling madrone in November and December and will use either the tractor and Farmi winch or the bulldozer to pull logs to the limbing area. I did find out last year that it is possible to tip the tractor over on its side when trying to winch in a large madrone log - with slightly too much angle on the drag.
6 cords or 6 FACE cords? Around here it's mostly measured in face cords, which is 1/3 of a full cord. This is about 15 face, and about a years worth for us. I try to stay at least a year ahead also. Mostly hard maple, cherry, Hickory, some red and white oak and recently a LOT of ash. Fuggen beatles.
