When money is truly interest free it does not make economic sense to not take it and put your cash in the bank and draw some interest on it. Now, if you have any other debt that charges interest then take cash you have and pay those debts off and make the payments on the interest free tractor (or car) loan. This can even go further for those that want to wait till they save enough cash to buy and pay cash. You save for 5 years or maybe 4 years till you have the cash then you go buy and the price of the tractor (car)has gone up 20% and then you also die 2 months later. Then the "Bango picker" that fills your shoes thanks you ever time he rides around on your tractor (car).

OK, I know life isn't (should not be)instant gratification all the time but money has no real vaue other than what it will buy you or your family or charitable causes. I'm not saying go into debt you can't pay and know you can't but if you can pay it off then consider the options. Wait and wear yourself out or save yourself some wear and tear with a smile on your face. Now, to true interest. Go make your bottom line deal for the tractor (car) being financed. Tell them you'll decide the next day. The next day come back and offer a cash price some hundreds of dollars less and see if they will take it. If they will take less for cash then it wasn't truly 0%. If they say no, it's the same price, then it's truly 0%. As has been mentioned before,
the company is not going to lose money so the 0% is built into the price but everyone is paying for that interest cost including myself as a borrower whether they take advantage of it or not. So, you cash buyers keep on doing what you are doing for us financing buyers (the majority of buyers), your saving us money or paying our interest for us. One other point, hard times come up and you have this debt of $xxxx thousand dollars. The tractor (car less) has some value and can be sold to pay off the debt so your probably not going to lose your home because of a tractor purchase. You'll just have to go back to using a push mower.
