I just purchased a L4740 and RTV900, both with 0% 42 month financing last month. I believed they required a 20% down payment. From what I could see on the Kubota website, none of the Grand L 40 nor RTV series are available at the 0%, 48 mth financing plan.
As regards insurance coverage, my understanding is that with ANY financing plan, Kubota will require documentation of appropriate insurance coverage. Since I have a farm policy for my house and 20 acres, I figured I would have sufficient machinery/implement coverage so as to not require additional outlay. Guess again. After speaking with my independent insurance agent, he informed me that with items up to about $5-6,000, I would likely be ok if I had a claim and filed it with my carrier. For more expensive items, it is best to have each piece listed separately on the policy. That way, if there were a loss on or off premises, there are no questions asked and they pay for REPLACEMENT cost. If not listed, and a claim occurs, they may 1) ignore it completely since it isn't listed on the policy (likely), 2) give you what you paid (unlikely), or 3) possibly pay you what they deem it's worth, which is likely thousands less that what you paid. As I said, my agent is independent from my insurance carrier so I don't feel he was just fishing for increased commission. What he didn't want, and has seen occur in the past, is a claimant show up at his door expecting coverage and receiving a unpleasant surprise instead. This leads to bad blood between agent and client.
I opted to go with my farm policy carrier for the coverage. In my case they were actually cheaper than Kubota for the same coverage. I believe I'm paying about $260 annually for both the tractor and RTV. In any case, ALWAYS check out your coverage before you take it home. The insurance industry is riddled with the statement, "But I thought I was covered".
