6.1.1.13 Calculation of the tyre load capacity
The tyre load capacity of the tractor's front and rear axle tyres should be designd for
the actual weights of tractor and implement.
Take the tyre load capacity of the tractor tyres from the operator's manual for the
tractor or from the files of the tyre manufacturer and double (two tyres per axle).
Tyre load capacity of the front axle
V
RT
=
double the value of the front axle tyre load capacity
Tyre load capacity of the rear axle
H
RT
=
double the value of the rear axle tyre load capacity.
Enter into table (Fig. 133):
• Tyre load capacity front axle
V
RT
• Tyre load capacity rear axle
H
RT .

Danger
The actual weights in the table (Fig. 133) must be smaller or equal (
≤
) the
permissible values!
Otherwise the machine can not be couples onto the tractor upon which the
calculation was based.
Danger
Only couple the machine on to the tractor after the calculated front ballast (see
Fig. 133/
min
V
G
) has been attached to the tractor!
Otherwise the machine can not be couples onto the tractor upon which the
calculation was based.
