I'm not all that impressed with tractor data.com There is so much more they could do by just looking at all the data.They could for instance tabulate the factory runs of each spare part and know and tell you what each tractor model has for average repairs and their costs. they could also discern from spare parts orders how many of each tractor model are still in service.
They can't even be bothered to tell you how many of a model have been made if the run is not yet complete. You would think that they would have data up to date at the end of each model year including serial numbers and just have a note that the current year was on going.
What they tell you is fine and quite useful but they could be so much better.
