1. Calculation of minimum front ballasting
with rear implement:
Enter the result into the table.
2. Calculation of minimum rear ballasting
with front implement:
Enter the result into the table.
3. Calculation of the real front axle load
Enter the result of the calculated actual front axle
load and the permissible front axle load from the
operating instructions of the tractor into the table.

4. Calculation of the actual total weight
Enter the result of the calculated total weight and
the permissible total weight from the operating
instructions of the tractor into the table.
5. Calculation of the real rear axle load:
Enter the result of the calculated actual rear axle
load and the permissible rear axle load from the
operating instruction of the tractor into the table.
Checking the calculation
Check the calculated values additionally be
weighing:
Weigh the front axle load and the rear axle load
on the entire tractor (with implement and bal-
lasting). Compare the measured values with the
permissible values:
•
permissible total weight
•
maximum front and rear axle load
•
Minimum front axle load (20 % of the tractor's
deadweight)
