Agreed, it is hard to make blanket statements on resale value, utility and such without knowing just about every detail of someone's situation.
I know a guy who is in hospice care right now and the resale value of his tractor was of no consequence I suppose as he never intended to get rid of it. No one in his family cares about the farm, tractors etc and it will all be sold.
I have two sons and grand sons who will use all the equipment we own long after I am gone, so resale is not that big of a deal, but it is nice to know they can upgrade without a big financial hit like we recently took on another tractor.
We can only give general advice/opinion and leave it up to the poster to sift through it. The other option is to just keep quiet just in case our advice doesn't quite fit that person because of some unique or unknown/unrealized factor.
To give point on advice a poster will have to provide pictures, soil types, finances, perhaps a marital assessment, financial statements, earning reports, retirement plans, family demographics etc and then we can bore him or her with a lengthy treatise in which no one will take the time to read.
I don't know about everyone else, but if something gets too long or is too much trouble, I just might move on.
