APPENDIX Combination of tractor and mounted implement
Combination of tractor and mounted implement
The mounting of implements on the front or rear
three point linkage shall not result in exceeding the
maximum permissible weight, the permissible axle
loads and the tyre load carrying capacities of the
tractor. The front axle of the tractor must always to
be loaded with at least 20% of the unladen weight of
the tractor.
Make sure before buying an implement that
these conditions are fulfilled by carrying out
the following calculations or by weighing the
tractor/implement combination.
Determination of the total weight, the axle loads, the tyre load carry-
ing capacity and the necessary minimum ballasting
For the calculation you need the following data and see the table of page E:
T
L
[kg (lb)] Unladen weight of tractor
T
V
[kg (lb)] Front axle load of unladen tractor
T
H
[kg (lb)] Rear axle load of unladen tractor
G
H
[kg (lb)] Combined weight of rear mounted implement/rear ballast
G
V
[kg (lb)] Combined weight of front mounted implement/front ballast
a [mm (in)] Distance from centre of gravity for combined front
mounte dimplement/front ballast to front axle centre
b [mm (in)] Tractor wheelbase
c [mm (in)] Distance from rear axle centre to centre of lower link balls
d [mm (in)] Distance from centre of lower link balls to centre of gravity
for combined rear mounted implement/rear ballast
