4. Counterweight
The stability of the tractor-loader unit can only be ensured with
a counterweight installed on the rear of the tractor. This should
ensure that 20% of the gross weight (tractor, loader, implement,
maximum load and counterweight) bears on the rear axle of the
tractor for optimum working safety.
The formula below is used to calculate the counterweight (M)
(standard EN12525 + A2 2010).
— G: Load on the rear axle, with no counterweight, with empty
implement (kg).
— G1: Load on the front axle, without counterweight, with empty
implement (kg).
— b: Distance from front axle to the implement's centre of gravity
(mm).
— I1: Distance from the linkage arm pin to the rear axle (mm).
— I2: Wheelbase (mm).
— N: Usable load of the loader for implement pivot point (A)
horizontal with the loader pivot point (B) (kg).
— P: G + G1 (kg).
— M: Counterweight (kg).
