This is my first post. I've been a tractor owner, used 2016 4550 w/ 400 hours, for 2 months, bootstrapping on everything tractor related. My wife and I really like the tractor but the fumes are a show stopper. After bush hogging 4 hours 5 days ago, my lungs were so sore they still aren't completely back to normal. (I had years of daily exposure to diesel when I was young though, so that might explain the over-reactivity now that I'm a geezer). So I'm super happy to see this and will try it out tomorrow.
I'm curious though, why would hanging down 18" make the difference?
