Setting frame Bergmann M1080 v1.0

Hi
Here I have the manure spreader Bergmann M 1080 setting frame.
Capacity: 6000 Liiter
Price: 15200
Washable
Log-free.
There is a problem: when he is on the dolly does not the helper.
If he is on the road does the helper.
It depends on the truck with the spreader it still a dolly with spreader to work the helper of the spreader on the dolly, but with restrictions: you must turn on the spreader and passed as the helper.
Have fun
