The grain cart is the heaviest thing most fields see all year, and it runs when the soil is least able to take it. Loaded, a 1,200-bushel cart on tyres can push 25 pounds per square inch into ground that is still shedding water from an October rain.
Ridgeline's GC1200 answers with 910-millimetre tracks on each side and a frame geometry that keeps the load centred between them as the cart fills. The company quotes 9 psi fully loaded, roughly a third of a comparable tyred cart.
Ruts are next year's problem
The argument for tracks has never really been about getting stuck. It is that the ruts and compacted bands left behind in a wet harvest still show up as thin rows the following season, long after the cart has been washed and parked.
The trade-offs are cost, road speed, and turning damage: a tracked cart scuffs sod on tight headland turns in a way tyres do not. Ridgeline recommends wider turns and offers a steerable axle option for operations with grass waterways.
