Evening geenhorn and gml,
Sounds like your a handy bloke to have on the welder

This is very interesting! Your suggesting this is a very late model tractor! My own tractor is from '82 (I think) and also has a green sticker. And the black striped nose decal seems more 'forward' looking than retro now that I think about it. But what about the mudguard style? Perhaps I'm wrong about that too.
Very interesting info on the intention to remove the aluminium nose cone post '82. Is this from memory or documents? Either way I'm super keen to hear more!
About the belts for the 'red'. Wher did they get these sizes? Are you saying they have a catalogue for that old girl?
gml, if your interested I now have the belts off my beast. If you like I can pop into the bearing shop with them and get them to measure them on their device. Now That I think about it if everything else is equal we could have taken that belt size and measured the height difference between the g40 and the g65 and been be able to come up with a good number for your mates machine geenhorn.?? Should have thought of that earlier.
Cheers,
