I joined a quite friendly wood burning stove website while doing research for a new pellet stove and received a great tip!
The bags of pellets that our new stove will burn are 40lbs each and will be in a separate garage, I worried about having to bring in a bag while dear husband was at work (though he will keep me stocked most the time).
Someone replied to use child's snow sled. He has dragged it over snow and mud! He also suggested spraying nonstick cooking oil used on frying pans to make dragging a sled easier. Though a bit tougher I bet I could haul something over grass or dry dirt if I had to.
Hopefully this might help some of you with mobility issues move heavy things too.
