In addition, what is the impact on tire traction and soil compaction? Dave Paulk: manager of field techni- cal services, BKT USA Inc.: There are several important reasons for using ballast on tractors. Adding weight where required will improve traction and reduce slippage. Managing the ballast and tire inflation pressures can maximize traction, minimize compaction, increase the life of the tractor drivetrain, and increase productivity. ere are general guidelines for ballasting a tractor based on the type of equipment being used. A Mechanical Front Wheel Drive (MFWD) tractor should weigh 120-145 pounds per PTO horsepower. 130 pounds is a common weight used per PTO horse- power. e weight split should be 35-40% of the weight in the front, and 60-65% of the weight to the rear. Some manufacturers recommend a 35-65% weight split as it makes it easier to control power hop. Implement dealers have calculators to best determine weights and weight splits based on the type of equipment being used and recommended by the manufacturer. Cast weights and liquid can be used to ballast tractors. Both have pros and cons. Cast weights on MFWDs and 4WDs are easier to work with if power hop becomes an issue.
