I can break it down as far as I was concerned.
I had no intention of paying as much, or MORE for a used tractor vs. a brand new one. A lot of people do this. I don't understand why. Used is used. In ANY other equipment or vehicle purchase, traditionally used pieces are significantly cheaper. The older and "more used" the bigger the cost savings vs. new. Lawn mowers, weed whackers, pressure washers, generators, chain saws, just about any other type of equipment you can think of, there is a discount in price (and it's usually significant savings) when you purchased a good, clean used one. Not tractors.
Now at this unusual instance in time, used vehicles seem to be collecting a premium price vs. even a few years ago, so for right now, the used vehicle market is a bit skewed. But traditionally, vehicles in general (unless you had something "special") saw a significant price drop in the first few years of ownership. Someone could buy used and get a significant savings over new price, and that would help offset the RISK of buying used, and offset not having a warranty that would cover big ticket stuff like a failed trans or engine.
But somehow, "magically" as soon as you say "tractor", we're all (potential buyers) supposed to be ok with paying as much, or more for a used tractor than a new one. When I was out tractor shopping 4 years ago, the ONLY used tractors I saw were either nearly destroyed garbage, OR they were asking for the same money or MORE money than a new one. Now for me, I wasn't interested in garbage. I know some people even like garbage tractors, even proudly post pictures of them here on TBN. That's fine. Really. Wasn't what I was particularly looking for, so not an option when I was a buyer. I also wanted "modern" features like a heated cab, FEL, 4x4, etc, that you don't see on used garbage.
4 years ago was "B.C." (before covid), so that can't be used as a market excuse for unnaturally high prices on used tractors. I saw ads for several tractors that appeared to be good, clean, used tractors. Guess what? They wanted as much or MORE for their used one, than the equivalent model sitting new at the dealer. That's always going to be a "nope" in my book. Always.
New means I don't have to worry about what some total idiot may have done while abusing their machine. And yes, there are some brain dead idiots out there in the world. Some of them own tractors. Go watch some "tractor fail" type videos on Youtube. You'll be thinking, "I don't want to buy anything from that idiot". I also don't have to worry about ANY breakdowns for a while ("bumper to bumper"), or worry about power train issues in the first 4-6 years due to power train warranty. And I've not said anything about the financing, as for me it didn't matter if I could finance a new one at 0%. Didn't really factor into my decision to buy new, but it's an option for many to be considered.
