Just wondering if any KUBOTA BX Lawn tractor owners are having a problem with the front exhaust blowing back on them.My dad bought a new KUBOTA BX2680 2 weeks ago and he loves it for all the cutting he has to do at our tobacco farm.Only complaint is the front exhaust that blows back on him on a windy day.Wonder if there is a exhaust extension that would blow the exhaust in another direction.Dad suffers from vertigo and the exhaust is making him feel sick.Hope there is something he can do to fix this.Any info and help on this appreciated....
