Kubota dealers only have KTAC (owned by Kubota) to offer. I was told it was mandatory on Kubota financed tractors; because it covers just about everything except abuse, wear and tear, or maintenance. That way they are protected till it is paid off. There have been other stories here though, also. It paid my $8K damage claim that other insurance I know of would not have. I keep renewing it now.
Stop by a dealer and they will tell you all about it.
