Hi P.G. there was an edger attachment that was produced for the Model 45, there were one or two complete, brand new, unused in the box, on E-Bay a while back....sold for big $$$.
Guess what! They don't work...it is driven by an extension to the upper engine shaft by a 'V' belt
external to the chain case to a flimsy blade assy attached to the lower left hand side next to the height adjuster handle.
To operate the edger, the cylinder reel (which can't be disconnected from the drive train, because it is also connected by chain to the engine shaft) is also spinning, not on grass, but often running dry with the machine having to run along on the concrete path! The complaints to Scott Bonnar were such that they withdrew the attachment from sale and discontinued it's production!
I have no info on one for the Diplomat.
