The 8850 John Deere 4WD Tractor with dual wheels was originally part of the 8050 series built between 1982-1988. Now the diecast models are made by Ertl.
This one, the 8850, was the only model by John Deere with a V-8 engine. However, wear and tear when using the tractor in the field caused damage to that engine and many farmers found the only solution was to have that V-8 removed altogether and replaced with Kinze re-power operation that put in a different engine altogether. Then it served well for many years. Those looking to buy a used tractor for the farm, often find the 8850 – especially if it had the engine replaced – is a good deal.
For this reason I think farmers that have good memories of a reliable tractor in this model will be the ones who want to buy a diecast model of the 8850 John Deere. Others may do so too, of course.
