Morning Jace,
I'd looked at that one on Gumtree. Of course being in SA and I in QLD meant I couldn't pursue it.
It's a first generation Greenie. The main indication is the front 'axle' (not the right term but I can't think of the correct one) pivots above the axle. Ever after they nested it into a U channel and pivoted it thro' the centre. The other thing is it is a single drive belt from the engine to a dog clutch on the cutter housing. The next model had both the drive and cutter belts going to the engine.
People refer to them as an HD8. Technically I'm not sure this is correct as I havnt seen Geenfield use that term in their literature until the next model. Original colour is red.
Not too many in running order. I'd be keeping it for resto too

I have a couple of these and a HD8. I'll do a collection photo when I finally get them all home. I only have one here.
Good to have you on board.
