Front tool:
2) Calculation of the minimum rear ballast weight M2
minimum
Write the minimal additional weight in the chart.
M2
minimum =
M1 x a - T2 x b + 0.45 x T x b
b+c+d
3) Calculation of the actual load on the front axle T1
real
If the front tool (M1) is lighter than the minimum load required at the front (minimum), increase tool weight
until the required minimum front load is reached
Indicate front axle calculated load value and the one indicated in the tractor operators' manual.
T1
real =
M1 x (a+b) + T1 x b - M2 x (c+d)
b
4) Calculation of the total weight M
real
If the rear tool (M2) is lighter than the minimum load required at the rear(minimum), increase tool weight
until the required minimum rear load is reached
Indicate calculated total load value and the one authorized as indicated in the tractor operator's manual.
M
real = M1 + T + M2
5) Calculation of the actual rear axle load T2
real
Indicate rear axle calculated load value and the one indicated in the tractor operator's manual.
T2
real =
M
real -
T1
real
6) Tyre carrying capacity
Indicate double (2 tyres) the authorized load value (see tyre manufacturer indications).
