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)
