I'm not familiar with the KTAC insurance. I'll look that up - thanks for mentioning it.
Regarding the dealer, there are two Kubota dealers in my area. When I worked for the municipality we dealt with both. They were both nice to deal with and responsive (but this was on State contract purchases for large tractors and batwing mowers). I expect/hope they would be equally responsive on non-commercial sales.
Running through the on-line "build my tractor" tool, there seems to be some options/info missing. For example the "60" Fine-cut deck says in the brochure there is an optional mulching kit, but there is no such option on the build-my-tractor tool. Also, I want the "Easy Drive Over" deck feature, but it doesn't come up as available with the Fine Cut deck. So I'll need to go over these questions with the Dealer.
I'm going to head over this Saturday.
