Worksheet to Calculate Ballast Changes

IMPORTANT: Ballast should not exceed weight required to result in recommended percent slip at 6.6 km/h (4.1 mph) MINIMUM.

NOTE: Complete this entire worksheet before adding or changing any ballast, or air pressures.

1. Determine desired weight split for your operation.				____ % Front
2. Record desired weight of tractor (See Ballasting Guide).				_______
				Front	Rear	Total
3. Percent of Weight Split from Step No. 1 multiplied by Step No. 2 (Desired Weight) results in Total Front Weight. For Rear Weight, subtract front weight from Total Weight.				________	________	________
4. Weight of tractor as determined from the UNBALLASTED TRACTOR WEIGHT CHART, in this section, or weight from scale.				________	________	________
5. Ballast needed (subtract tractor weight in Step No. 4 from desired weight in Step No. 3				________	________
6. Add ballast.				________	________
7. Add ballast from Step No. 6 to weights from Step No. 4.				________	________
8. Set tire pressure for operating conditions using weights from Step No. 7. (See appropriate inflation pressure table).					________
NOTE: You are now ready to test for wheel slippage. See MEASURING WHEEL SLIP, in this section.
