Crops grown in soils damaged by compaction are less likely to survive moisture extremes such as heavy rain and droughts. Correct ballasting for field work is entirely about ensuring that slip rates are kept in the best window that allows optimum tractive efficiency & drawbar pull. Having good rear ballast is especially important when you have a front end loader like I do. Implements with large draft requirements, such as primary tillage tools, should be sized so they can be operated at minimum speeds of at least 4 or 5 miles per hour. Therefore, a 300 hp tractor should weigh approximately 30, 000 to 36, 000 lbs.
