Determine Maximum Rear Ballast

IMPORTANT: DO NOT overload tires. If maximum weight shown in chart is not enough for safety, reduce load or install heavier ply tires.

To extend drivetrain life, avoid excessive soil compaction and rolling resistance, avoid adding too much ballast. Ballast should never exceed the weight required to provide traction for continuous full power loads in 3rd gear for 2-WD tractors. Remove ballast if tractor engine labors when pulling heavy loads in the first three gears. When using mechanical front wheel drive, ballasting to one gear slower is appropriate.

Chart shows carrying capacity per tire.
