<font color="blue"> If a dealer lends out a tractor to a farmer for a period of time can they still sell it "as new or like new" to someone else? </font>
My take on the original question is that the tractor was used by the farmer as a test unit, perhaps with the dealer thinking the farmer would buy it, and the farmer perhaps also thinking he would buy it buy it, but for whatever reason the farmer did not buy it...but used it for thirty hours.
In my mind the first 50 hours are the most important AND the most costly.
If one bought a new tractor and used it for only 30 hours and tried to sell/trade it, how many bucks would he lose on the deal? 30 x 10 = $300? unlikely. I might actually cost one $100 dollars per hour to use a new tractor for 30 hours and then sell/trade it off.
Did you person who the tractor was loaned to treat it properly during break in? Was it ran hard from hour one?
Frankly, I would fear buying a tractor that was loaned and used by someone for 30 hours, much more than I would worry about buying one from an owner who had one for a year and had 100 or 150 hours on it.
I might be an idealist, but the first 50 hours of break in are very important to me, especially if I am intending to keep the tractor for a lifetime. If I were only going to keep it for a few years and then trade it on something else, that would be a different story...
Personally, if I could not get at least a $40 per hour price reduction (actuallly I would need more than that I think) on a loaner tractor with 30 hours on the meter, I would buy new, with 1 hour on the meter.
And remember, if it is a tach-driven hour meter, the tractor could have many more actual hours of use on it, if it was not worked at full pto rpm for the number of hours shown.
