Hey guys. I want to start a topic solely on the exmark navigator. There are plenty of comparison threads between the nav and walker. I really don't care to get into that here. I would just like to discuss tips and tricks, pros and cons ect for all of us with a nav or thinking of purchasing one. One thing I noticed is since owning mine, is that they get really dirty from a short amount of use. I assume because its a bagging unit, there is debris that slips by the shoot and gets spread around the engine bay. So one tip is try to blow these machines off at least everyday to keep debris from piling up. I usually take my backpack blower and raise the seat and hopper and blow it off at the end of each day. It's a good habit to get into with all of our equipment since its used so much and to make money.
