Wheel loaders weights v1.0

Hi
Here I loaders weights. There are four different weights.

Heckgewicht for JCB wheel loader 3000kg
Heckgewicht for NH wheel loader 3000kg
Heckgewicht for Liebherr wheel loader 2700kg
Heckgewicht for Liebherr wheel loader 4000kg

At the weights for NH and JCB is for technical reasons no trailer coupling
At the weights are clutches.
ATTENTION: the weights for the Liebherr no further weights Hitch. It can cause the vehicle and the weight is then round kick uncontrollably when uncoupling and re-coupling.
