I need wider tires so I don't make ruts in homeowners lawn hauling wood out.
Crosscut,
unfortunately you should have figured out exactly what you needed THEN
bought the tractor to fit your needs/application because changing to a wider tire is really not an option now. It's not the same as other types of equipment that was designed to take many different sizes of tires or like what so many commonly do with a 4X4 pickup truck jacking it up and adding a bigger set of tires for off road use or mud bogging etc.
Your tractor was designed and engineered to work with the tire options that are available and any change to the front end width wise will put more strain on the front end bearings axles etc than it can take and you will break it and it will be VERY expensive to fix when you do that. It's one thing to change from Ag to Industrial to Turf in sizes the tractor came with from the factory to keep from tearing up the lawn but going wider up front is not something you can get away with doing.
