Many machines, many loads
Farms can see tractors, harvesters, sprayers, trailers, trucks and earthmoving machinery with different tyres, tracks, axle loads and operating weights. Unlike a road network, the farm does not operate under one standard wheel-load configuration.
Moisture changes the problem
The same machine crossing dry soil may affect it differently from wet soil. Traffic histories can overlap with changing soil moisture, creating non-uniform conditions that may not be obvious at the surface.
Animals add another traffic layer
Livestock can concentrate around gateways, watering points, feed areas, laneways, shade and frequently used routes. Stocking, soil type, moisture and duration all influence the effect.
The underground landscape
Compaction can vary across depth and location. Field investigation—not appearance alone—should establish whether a suspected compacted layer or uneven pattern actually exists.
Correct the cause as well as the surface
Repeatedly repairing a surface without understanding why it changes may provide only a temporary result. The scraper is a physical correction tool when grading or redistribution is appropriate.
