Sirs,
Did I read here to put facial surgical mask on the air element intake? Ya? What?
What you need to do is to fab up a pre-cleaner bowl for your air intake. The tractor I just bought - tested the oil, shoiws too much dirt, not good filtration- maybe sllers environment, maybe not. i'm wrtring up the fab tomorrow or wednesdsay and will share what i would do to helpt this situation, again, in my humbel opinion.
I don't think putting surgical masks on the element will help, personally. The tractor ain't a human afterall.
