Beautiful completion of the fleet

Available are with me from Siku Control MAN with low-loader (6721), the Fendt 939 with front loader (6769) and the (obsolete) John Deere 6920S and other vehicles Siku-Control series. The Dolly SIGA Duo is a meaningful completion of the Siku Collection since the two tractor trailers of the MAN now also can draw itself. The entire fleet is now much more versatile.

Benefits:
==================
- The whole part is comparatively heavy and makes a very strong impression, including the mechanism for locking and releasing the trailer coupling
- The tractor can the dolly coupling and uncoupling without being engaged by hand, because the drawbar is immobile.
- The tractor can drive with Dolly and hitched a little practice back at the waiting trailers without having to intervene.

Disadvantages:
==================
- The team of Dolly plus loader is difficult to pull even in the Fendt 939. Nor is it a vehicle and it goes around the curve, turn well before the wheels of the tractor through.
- The fact that the drawbar is rigid, it also dissolves before the pulling tractor, especially the John Deere 6920S.
