If pressure is very high for the load being carried, the tyre surface area supporting the load reduces, which in turn means a higher risk of slippage and increased tyre wear.
Tractors
Did you know that using small implements with large tractors reduces their energy efficiency?
When a tractor runs at low load levels, its daily consumption will also reduced, but when it uses a relatively narrow implement its work capacity reduces and fuel consumption in litres per hectare will thus increase.
Tractors
Did you know that modern tractors do not reach their top power when the accelerator is pushed to the floor?
Maximum power is reached under conditions between about 1900 and 2000 revolutions per minute. In addition, this consumes less fuel and there is less motor wear due to the fact that it is turning over more slowly.
