CAUTION! The permissible loads on the axles and tyre load capacities must
not be exceeded. The front axle load may not be less than 20%.
Axle load calculations
Key:
GC
–
the tractor weight,
TP
–
front axle load for the unhitched tractor,
TT –
rear axle load for the unhitched tractor,
GT
–
total weight of the rear
-
mounted implement,
GP
–
total weight of the front
-
mounted implement,
a
–
distance between the centre of gravity of the front
-
mounted implement and the axle
centre,
b
–
tractor wheelbase,
c
–
distance between the rear axle centre and the centre point of the hitching pin of the
rear
-
mounted implement,
d
–
distance of the centre of gravity of the agricultural implement from the hitching pins
of the tractor,
x
–
distance of the centre of gravity from the rear axle (assume 0.45 if the manufacturer
does not provide this parameter).
