Rear tool or front-rear combination:
1) Calculation of the minimum front ballast weight: M1 minimum
M1 minimum = [ M2 x (c+d) - T1 x b + 0.2 x T x b ] / [a+b]
Write the minimum additional weight in the chart.
Front tool:
2) Calculation of the minimum rear ballast weight M2: minimum
M2 minimum = [ M1 x a - T2 x b + 0.45 x T x b] / [ b + c + d ]
Write the minimum additional weight in the chart.
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
T1 real = [ M1 x (a+b) + T1 x b - M2 x (c+d) ] / [ b ]
Indicate front axle calculated load value and the one indicated in the tractor operator's manual.
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
5. Axle load calculation
