Should I buy a good quality canvas tarp and cover my tractor?
I bought 3 like these before I had a barn. Got them at Menards, they were about $400 when I got them. Where you live I would not cover anything with plastic or tarps, they condense moisture on their inside surface and then it drips on your equipment and can't evaporate. They also don't allow enough air circulation so the equipment can't get to air temp quickly and it condenses moisture. If you lived in New Mexico or Arizona it would be different.
