Had play with it today had no luck,

It is the top belt that I am trying to adjust.

The only adjustment I can do is the plate under the gear box that lets me move the gear box back but doing this puts slack on the drive chain and then it fulls off.

Or do I have the wrong Belt?
A870/A870 is the one I have put in.

looking in the Rover parts list (Rancher_2_Models_11044,_11050,_11055.pdf) it is (35. A05071 Belt (7313)Is this the same?

Do I make the rear Pulley open up more by puting in a biger Shim
