Calculation
The measured values can now be inserted into the formulae.
Front ballast
Calculation of front ballast
for machines attached at rear.
Front ballast in kg =
Rear ballast
Calculation of rear ballast
for machines attached at front.
Rear ballast in kg =
Front axle load
Calculation of the actual front axle load
Front axle load in kg =
Gross weight
Calculation of actual total weight
Total weight =
Rear axle load
Calculation of the actual rear axle load
Rear axle load in kg = actual total weight - actual front axle load
Tyre load rating
Information about the tyre load-bearing capacity of the front and rear
wheels can be found in the tyre manufacturer's details.
•
The front tyre load-bearing capacity for two wheels is equal to twice
the permissible tyre load-bearing capacity of a single front wheel.
•
The rear tyre load-bearing capacity for two wheels is equal to twice
the permissible tyre load-bearing capacity of a single rear wheel.
Summary
Check if the following conditions are met:
•
The actual values for the rear axle load must be less than the per-
missible values given in the tractor's operating manual.
•
The tyre load-bearing capacity must be greater than the values for
the rear axle load given in the operating manual.
•
The actual total weight must be less than the permissible total
weight given in the tractor's operating manual.
If these conditions are not met, the machine must not be attached to
this tractor.
If you have a sufficiently large weigh-bridge, you can determine the to-
tal weight and the rear axle load by weighing.
