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. For tractors with IVT Transmission, add 233.1 kgs (514 lbs) to front axle and add 146 kgs (322 lbs) to rear axle.      
 
5. Weight of tractor as determined from the Unballasted Tractor Weight Chart or weight from scale. ________ ________ ________
       
6. Ballast needed (subtract tractor weight in Step No. 4 from desired weight in Step No. 3 ________ ________  
       
7. Add ballast. ________ ________  
       
8. Add ballast from Step No. 6 to weights from Step No. 4. ________ ________  
       
9. 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.
