Grumpy, just spoke to Greenfield again, they don't even have any copies of the original owners manuals. All they have left literature wise is just the parts lists.

Seems also that my particular mower has been through a few upgrades over the years. Majority of it still runs the standard 11Hp setup however some parts have been changed to the 12Hp parts like hand brake for instance. The standard 11HP Anniversary model runs a park brake disc with notches in it. Mine runs the allow drum brake version which was standard on the 12HP but retrofitted to the 11HP after a certain month. Also things like the flanged bearings etc are different.

This is really doing my head in having to consult two different schematics for one mower!! Haha!
