Sorry Moss, but I'm not reading it that way (plus it's 'legal weasel' lawyer talk, phrasing it in a certain way)... the rep specifically said that "It's recommended that they be done by a Deere dealership,".
Do tractors come from the dealership 'properly weighted and properly ballasted'? No, they don't. Sure, there may be a local 'deal' going on to load tyres, but does that specific buyer want them loaded in the first place? Loading the tyres, wheel weights and a ballast box are all extras to be added to the cost of a new tractor. Dealerships (all colours) are not mind readers and don't know what/how the new owner is going to use the tractor (+FEL). It was up to the owner to have these things done, either by himself or by the dealership. Same thing with widening the wheels for stability, the owner can do it or have the dealership do it.
Of course the dealership (any colour) will recommend that they do the work.
I believe that the tractor was going to be used in a new mowing 'venture'... that says 'slasher' or 'finish' mower normally hanging off the 3PH (yes, I'm assuming here) = plenty of ballast for normal FEL work (depending on the FEL load and height carried). Apparently, no ballast was present = overloaded/un-ballasted.
Nobody was negligent, the owner (through inexperience) was ignorant.
[And I say 'ignorant' in the purest form of the word.]
