Ha, wonder what the OP needs a brush shield for, in a way I could use one on my Cruze. New liability laws on airports are requiring private contractors to carry a million bucks of liability insurance to mow the grounds and clear off the snow on runways.
A farmer with a brush cutter can no longer charge ten buck an acre nor afford this kind of insurance. So they are just letting this brush grow. I also need this coverage now, and for a couple bucks an hour for certification of aircraft ground navigation avionics. No longer worth my effort. And not about to plow through brush to get there. So I quit.
Going through major talks now, next nearest certified techs are over a thousand miles away. And will cost them a small fortune to have them drive over here. Not about to risk everything I own to help them out, but waiting to see what happens.
Without this equipment, would have to shut these airports down. Or just limit them to fair weather use.
Ha, back to the original question, what does the OP need a brush guard for and along with a high performance engine.
