It can also cause drivetrain problems, increase soil compaction, and reduce efficiency.Īir pressure in the tractor tires also greatly affects soil compaction. This can cause tire failures by tires slipping on the wheel, and lug cracking. Over ballasting also has a potential for problems. Too much slippage effects fuel consumption, field operating time, and tire wear. 5-15% slippage is considered in the normal range with 8% slippage considered optimum. If tractors are under ballasted, there is too much slippage. There are potential problems that can be discarded by the correct tractor ballast. As the drawbar load dramatically increases in downward pressure, the weight splits need to move back to around 60-40% for optimum performance. On 4 WD’s for towed implements, a 55-45% split (55% front and 45% rear) would probably be near ideal as this helps to control power hop. These lighten the front end and may require more front weight. The exceptions could be heavy implements on the three-point hitch or implements that place large loads on the drawbar such as rippers. Once MFWD tractors are set up with the proper weights and distributions, they can basically use any type of implement without having to change weight distributions. When adding or removing ballast, the proper weight distributions should be maintained for the tractor type. Fluid is more economical than cast weights, but fluid is harder to change. Cast weights are the most convenient and can be changed according to ballasting needs. ![]() Cast weights on MFWD’s and 4 WD’s are easier to work with if power hop becomes an issue. Implement dealers have calculators to best determine weights and weight splits based on the type of equipment being used and recommended by the manufacturer.Ĭast weights and liquid can be used to ballast tractors. As in the case of the MFWD, power hop can be controlled by moving some weight from front to rear based on the equipment used. This could change some due to the type of implements used. 120 pounds is a common weight used per engine horsepower. A general recommendation is a 60-40% split, with 60% of the weight in the front. Some manufacturers recommend a 35-65% weight split as it makes it easier to control power hop.Ī 4 Wheel Drive tractor should weigh 85-125 pounds per engine horsepower. The weight split should be 35-40% of the weight in the front, and 60-65% of the weight to the rear. 130 pounds is a common weight used per PTO horsepower. A Mechanical Front Wheel Drive (MFWD) tractor should weigh 120-145 pounds per PTO horsepower. There are general guidelines for ballasting a tractor based on the type of equipment being used. Adding ballast to a tractor is an effective way to get the power of the tractor to the ground. Managing the ballast and tire inflation pressures can maximize traction, minimize compaction, increase the life of the tractor drivetrain, and increase productivity. Adding weight where required will improve traction and reduce slippage. ![]() ![]() Tractors and combines often have to add weight to accommodate horsepower imbalances.
