Front mowers must be properly ballasted for both good performance and safe operation. Ballast requirements differ depending on the front mower model and the implement being used.

The chart below gives the minimum ballast requirements for the various product configurations. Additional ballast is recommended for operating on slopes or other conditions that may warrant it.

NOTE: Use only implements and accessories recommended by the manufacturer.
