I can tell you the view from an auto dealer.
We are not allowed to take Ford 6.0 or Ford 6.4 trucks on trade in. Here is what happens:
1) A guy wants to trade his Ford 6.0 and we're not allowed to keep those on our lot (not starting a brand war, but if you know, you know.)
2) So we have to look at auction results on similar 6.0s. And offer 20% less than those auction results to cover our time and our risk.
3) When we go back to the customer and offer him 20% less than auction results, he gets mad and storms out. So we lost the sale and a potential customer is mad.
Much easier to just say we can't take those in on trade.
Seems crazy to still not take 6.0L's in trade, at this late stage in the game. The newest 6.0L equipped trucks were from 2007, and vans from 2010. Anything that old is going to the auction anyway. The sad thing is by now, the problems of the 6.0L are well known and there are fixes for all the problems, mostly from International / Ford updates, but also from the aftermarket. Once done, they are pretty nice engines.
In 2020, I was given $11,000 as a trade for my 2012 F-550 on my Ram 5500. I drove it to the dealer, it was leaking oil and smoking when I pulled in, so I drove it to the back part of the dealers lot. That was a huge relief to get rid of. I was delighted to get 11K as a trade. Not much interest as a private sale. Best offer I got was 12k and the guy interested was shaky at best.
I took the 11K and ran for the hills.
Dealers will lowball, but $11k for an 11 year old 550? Was it 4x4? Really high miles? Rusted out? That seems extremely cheap. Was it a V10 or the 6.7L? We've got a 2012 F-550 6.7L diesel 4x4 that's been nearly bulletproof, had the DEF tank heater failure and both NOx sensors fail, but otherwise nothing. Then again, I have a friend in the excavating business, he also had a 2012 550 diesel dump truck, with 60k miles on it (but 7 years old so out of warranty) the engine crankshaft broke!
This is interesting since Green tractor parts are manufactured in India right next to their Ref tractors.
Not all of them are. Many people think there's nothing more American than a John Deere tractor, but a lot of the mid-size utility tractors are in fact made in Pune, India. The large, Ag-oriented JD tractors are made in USA and are very good machines. Some of the smaller JD tractors are made in the US, but almost all the smaller JD machines (<75HP I think) have Japanese-made Yanmar diesel engines.
Most automobile dealerships will take any car in trade these days, but that's because the auto brands are all well-established and its not particularly hard to get any brand of vehicle repaired or serviced. Book values are also clearly established. With tractor dealers, from what I've seen and experienced, a JD dealer will take JD and Kubota trade-ins; a Kubota dealer will take Kubota and JD trade-ins. Some will take Massey or NH. Many will not take the Korean (Kioti, Branson, LS, TYM, etc) or Indian (Mahindra) tractors. The easy excuse is that they don't know how or cannot service these brands, reliably get parts, etc. There may be some truth to that. A lot of the Asian tractors (excluding Kubota) have factory-sold implements like a front-end loader or rotary cutter, etc...that are made by who knows who, and parts can be very hard to source. On a JD or Kubota, those parts are easy to source, plenty of service info, etc. Beyond that, there might be an intentional strategy of trying to lower value, or at least perceived value, of the 'value' brands by not taking trades. In fairness, the Korean and Indian brands do not hold their value as well and do not have as good a support system. They might be just fine for many users of course.
