    We are sorry to hear you are having challenges with your Exmark Navigator. Aside from putting more air in the tires, you can also try not filling the collection tub as full. Our Navigators will pack a lot of grass in the hopper putting additional weight on the tires. If you continue to leave marks once you start mowing again in the spring, please send us your contact information to exmarkpr@exmark.com and we will have one of our engineers contact you to work through some possible solutions.

    thank you very much for your concern and reply. one question: what are your feelings of putting wider tires on?

    Using wider tires will definitely reduce the surface contact pressure and reduce the effects of wheel scuffing. ItÂ’s hard to predict how much benefit that will be as it will vary widely depending on turf and moisture conditions, etc.
    Additionally, watch how you control your turns. Wheel scuffs are often made by allowing one wheel to remain stationary during the turn. When turning, use a combination of forward or rearward movement to always keep both tires turning. It takes a little practice, but if done properly can virtually eliminate any scuff marks. Beyond that, soft and wet conditions, such as those in spring when roots will easily pull out, will certainly add to the issue.

    So I talked to my exmark dealer and they stated the widest tire I can put in is an 11", which would only gain me a half inch. Can you confirm this for me that the widest tire I can put on is an 11"? he stated I would hit the frame with anything wider. Thanks.

    Operator error! Lol it just takes a little time to get use to them. So many variables from wet grass, slopes, ground speed ect. The more you use the machine to better you'll get at controlling it. Maybe they will come out with traction control for mowers like cars have.
