Basically your saying that the HD8 term belongs to the red machines and 'super' to the yellow ones? That's interesting. I'd been given to think that the HD8 term only started with the yellows as there is no HD8 decals or reference to the term on the IPC for the red girls.
You raise an interesting point here,
prd. Use of the 'HD8' designation for the 'old red' Greenfields is really just a habit we've got into at ODK, as a shorthand moniker for the 'second model' series. And that may not be quite accurate! That said, far from all of the 'third model' yellow 'Super 8's' we've seen have the HD8 decal on them, either.
The red machine pictured in this thread is apparently the very rare 'first model' Greenfield, going by its design features.
It's quite possible that the dual rear wheels are a factory option - they are mentioned in ads for the second and third model series, but are not shown in the IPL for either of those models.
Ah!, a bolt on double pulley. That makes sense. Not quite so easy to fit as the arrangement with the dog clutch perhaps but given the extremely poor sales it's purely academic, I guess.
Well, the dog clutch setup wasn't there so much for easy detachment, but to make it possible to disengage the cutter drive. We had one of those red painted T-piece PTO mounts in stock for years - it probably went to scrap when the business was sold. It's all history now anyway...
