Ours works the same way (7 yr term and no early payoff penalty) except the fees are minimal. Also, I have to agree with much of what was said in the various posts which is why I said (in my initial post) this is not for everyone. In my case, when we bought the tractor and all implements, we financed a little more than half. In addition, whether I continue through deere credit or move it over to the equity line, the loan will not run through it's normal term, rather it will be paid off in about a year so market volitility is not as big a concern as it would be for someone who is going to use all 7 years to pay it off.
