Yep, there are a number of design differences between the 'Super HD8' [as we shall call it henceforth], and HD8 models.
The most visible of these is the front axle mount. The drive setup is a bit different too, as the Super HD8 runs two belts from the engine - one to the wheel drive, which is constant drive; and one via the front manual clutch to drive the cutter deck or PTO.

Also, the PTO arrangement?
Righto; I had to give this some thought, as I've only encountered one of those front-mounted slashers; it was the only one we ever sold - over 40 years ago now!

The Super HD8 PTO setup was very similar to that used on the HD8, as depicted in the HD8 IPL excerpt below.

Component #1 here is the same frame used to mount the conventional cutter deck. For front slasher use, Component #2 bolts up to that frame from below. It has a vertical spindle mounted at the centre of the crossbar of the T.

For the Super HD8, a single double groove pulley is fitted on that spindle, as it doesn't need the dog clutch used on the HD8. The 'cutter drive belt' from the engine is fitted to the top groove, and the PTO belt runs forward to the slasher, from the bottom groove.

Cheers,
Gadge
