John Deere 7930
This movie is not about the tractor brand. It's about fuel consumption. It shows us that reduced tyre pressure when working in soft soil can save fuel. Reduced tyre pressure distributes the weight on a tyre over a larger area. Tyres are digging less deep into the ground which saves fuel. This also results in less tire slippage and less soil compaction. Of course the tyres have to be suitable for this. For transportation on the road the tyres should be inflated to the normal pressure again.
