The kubota insurance is for the tractor not to protect you from hurting others. Personally I think it is crazy to attach my tractor to my house. I also have a umbrella policy that covers liability but I have it for more of a backup to my auto policy. All I know is I filed a claim on my M last July and the claim was paid before the dealer had it repaired. Too cheap for me to pass up when I know my payment isn't going to go up even when I file a claim for the full length of my loan. best of luck to you whichever insurance you take. Skip
