Wait until the soil dries enough to support the combine. 

Don't use grain bin extensions or fill the combine as full. 

Use wide tires with lower inflation pressures. 

Keep trucks out of the field. Consider unloading at the ends of the field, not on the go. 

Grain carts should track the same rows as the combine. 

Don't turn around in the middle of the field. 

Don't fill the grain cart as full; unload more often. 

Establish a grain cart path and stay on it. 

Don't till wet soils as they are easily compacted. 

Use cover crops to help build soil structure.
