Calculation of tractor load limit
Connection of machines to the front or rear hydraulic arms must not exceed the allowed total load of the
tractor, individual axles and tractor tyres. Therefore make sure before buying the aggregation that these
assumptions are fulfilled using the following calculation:
The following data must be known for the calculation:
T
L
(kg) - instantaneous mass
T
v
(kg) - instantaneous front axle load
T
H
(kg) - instantaneous rear axle load
G
H
(kg) - total machine weight suspended in the rear / rear
load
G
V
(kg) - total machine weight suspended in the front /
front load
a (m) - distance between the gravity centre of the front
carried machine / front load and load through the centre of
the front axle
b (m) - tractor wheelbase
c (m) - distance between the centre of the rear axle and
the centre of fixing holes of lower hydraulic arms
d (m) - distance between the centre of fixing holes of
lower hydraulic arms and the gravity centre of the machine
suspended in the rear / rear load
