Ballast MFWD-Equipped Tractors

Ideal tire slippage for MFWD-equipped tractors is 8—12 percent. To reduce wheel slip to this level, more weight is needed on the front than with two-wheel-drive tractors. The ideal weight split is 40 percent front, 60 percent rear, of total tractor weight. In some cases liquid ballast will be needed in front tires to obtain this weight split.

NOTE: Implement codes are used to determine proper ballast for stability and steering control. Refer to the implement code in your implement operator's manual, along with “Using Implement Codes” in this section, to determine the minimum number of front weights that are required for your tractor model. In some cases, additional front ballast is required for optimum field performance. If more assistance is needed, see your John Deere dealer.
