Well, we said that about putting a roof on ours too. Then we got a tractor with a front end loader. It can lift the shavings HIGH to make a big pile, under that roof.
Kids and I had to put up with various tarps, systems that were removable for truck but held the tarp up off the sawdust. Did that for YEARS until kids were gone and husband needed to help me get tarp off the sawdust on a DAILY basis.
Fighting with tarp, “improved” systems to lift tarp to get under there failed last year with the tremendous snow load on top.
Husband put up higher sides on the bin and a tall roof so delivery truck can come, back up close, drop PART of the sawdust, then wait while husband pushes the sawdust to the back back, then piling it higher and deeper with the loader. Then driver dumps more of the load, same push it back, pile it higher, until the whole truckfull is under roof cover. Takes about 4 dumps to empty the 40 yards of sawdust in the truck, but doesn’t add much time having driver wait. Our sawdust folks are really helpful that way.
Have had the roof now just a year, LOVE being able to drive in with tractor and fill the bucket to do stalls.
Husband added cement to the bin as a floor. He was scraping up all the dirt when he scooped sawdust, so there were LOTS of good sized stones in each bucket full. I got tired of throwing stones when I dumped sawdust into stalls, and any I missed would get into the manure spreader. THAT rock throwing was dangerous, told husband to get some kind of floor to prevent rocks in the sawdust. Cement took a week of time to put in and dry WELL, before we got the next load of sawdust. Cement has been nice to work on for loading and with the big apron catching any spills so my barnyard is not under a layer of sawdust.
Get a roof, removes all that “tarp time” and anger when things are not going well. No more snow shoveling here!! My life is SO MUCH easier now doing chores. Kids said “Why didn’t you do that for us??”
