- To be checked :
• The total authorised weight.
• The permitted weight per axle.
• The authorised support weight on the tractor’s linkage.
• The permissible load capacity for the tyres tted to the tractor.
• Is the authorised linkage weight sucient?
All of this information can be found on the registration papers, or on the data plate and in the tractor manual.
FIGuRES THAT YOu SHOuLD KNOW
ð
M1 mini = Calculation of the minimum ballast need in front.
ð
P1c = Calculation of the weight on the front axle
ð
Pc = Calculation of the total weight of the unit (tractor + machine)
ð
P2c = Calculation of the weight on the rear axle
- Complete the table below :
- Check that :
• The values calculated should be < or = to the tractor’s permissible values and the values for the tyres tted to the tractor.
• It is essential that the minimum load on the front axle is > or = to 20% of the unladen tractor weight.
The machine musT noT Be hiTched To a TracTor if:
ð
The total weight calculated is > than the maximum authorised weight.
ð
The weight on the front axle is < than the minimum required.
