Truer words were never spoken.
When you buy a tractor, so long as it's a resonably good model/brand, it will USUALLY be worth what you paid for it at a later date. (unless you kill it;( )
When you have your own tractor on hand, there's a convenience factor over renting or hiring work done. You use it when you want, let it sit idle (without cost) when you DON'T want to use it.
At any point, if and when you feel like you're done, or just don't need it any longer, you can USUALLY recover your investment by selling. In SOME cases, even MAKE a few bucks on a tractor that appreciated in value, or where you got that "smokin' deal".
Where the "money pit syndrome" kicks in, is if or when you decide that you HAVE to have every implement ever built, or every accessory available, need it or not, or the dreaded "I need bigger/better/more/several/antique tractor(s)" mindset hits you. Happens every day.
In short, it doesn't matter so much how bad you NEED a tractor, as it does how well you manage your investment of that tractor. In all likelyhood, a great many people who buy new tractors don't NEED them nearly as bad as they think they do, but it sure is nice having one. And with prudent spending, they can actually SAVE you a few bucks over their lifetime.
