Hi Norm
Victa vac I have thought of but 90% of leaves aren’t on paths, it’s in the garden beds or paths with jarrah wood chips so a victa vac wouldn’t work – probably would end up with a bag full of wood chips. There was one a few suburbs away with a good bag for $150 last year but couldn’t justify it.
The ryobi is good because it is easy to poke under bushes and tends to not pick up much mulch if you are careful.
Looking at it, I reckon a regular ryan engine will fit – fingers crossed
