Calculation of Actual Front Axle Load [T3] of the Tractor
Calculation of Actual Total Weight [W] of the Combined Tractor and Sprayer(s)
Calculation of Actual Rear Axle Load [T2] of the Tractor
Calculation Compared to Permissible Values
÷
NOTE! Fill in the values in the fields above. You can find the permissible values for the total tractor weight, axle loads
and load capacities in the tractor’s registration papers or in the tractor documentation.
μ
ATTENTION! Add weights to your tractor at the front or rear, if the tractor axle load is exceeded on only one axle.
μ
ATTENTION! If you do not achieve the minimum weight at the front (W2
min
) from a front-mounted sprayer alone, you
must add front weights to the tractor.
€
DANGER! It is forbidden to couple the sprayer to the tractor, if one of the actual calculated values is greater than the
permissible value, or if there is no front ballast (if required) mounted on the tractor.
€
DANGER! When driving on hilly ground, the centre of gravity can change significantly for the combined tractor and
sprayer - allow for this when calculating the minimum ballast for the tractor as well as driving carefully. Risk of the
tractor turning over resulting in the driver being crushed or trapped. Risk of impact with the sprayer through
insufficient stability of the tractor and insufficient steering abilities and braking power.
