I'm not at all sure I would be interested in it, sure, my curiosity is urging me on something shocking, but in all honesty, I'm running out of space as it is, and i dont even have a tiller to begin with, let alone a compatible one.
althoug my mind keeps making crazy ideas, like converting the head of a whipper snipper to fit, or making 90 degree wheel adapters, and somehow mounting it to a model 5 victa.
But that's all getting a litle nuts!
How did you find out about the square drive, did you get in touch with the seller?
No chance you got your hands on more pic's did you?
