Well - with the backhoe attachment you might be able to make a half descent shelter. Be sure to "build" so that breezes/wind can blow under and prevent moisture build up.
One piece tarp going to be pain in the butt to cover tractor in the winter with wind blowing,maybe tube shelter might better until you decide on wooden cover.
Yes - I agree Thomas. Something temporary > perhaps made out of rigid plastic piping. Get the tractor adequately covered > get the tarp up and off the paint job.
Could add to it with side and end tarps to help protect from the winter weather. I don't like throwing a tarp directly on whatever you store. Seems that is what the critters like.
I store my Kioti DK55 outside in the winter. I buy the heavy duty tarps from Costco. The ticket is good quality bungie cords so the tarp can move a little if the wind gets too strong. Rope will stretch over time and the tarp will get loose. The tarps are 12x16 before finishing. The blue tarps at the big box stores all say heavy duty but they are just single ply crap and based on experience, I believe they dissolve in the rain.
Solid choice. I’ve run those shelters twice in my lifetime. First one last 4 years but had a second one right next to it. The second one only lasted two years in a wide open space. In case someone else comes across this post, I’ll second what someone else said, avoid standard tarps unless you plan on buying one a month. Ocean State Heavy Duty tarps have served me well and I finally found one I like. Covers my Kubota like a blanket. Four bungees with a light stretch is perfect. Tarps don’t like excessive force.
