ast about your tractor?
The plastic might scratch but it won't rust after it scratches like metal will,it will stand some impact before it breaks where as you bend the metal then you have an ugly old dent you have to look at,the plastic they make today is stronger than a lot of metals,not to mention being lighter as well.
