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 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.
