Hi Jack and all,
Thanks for that info Jack.,I just didn't think you can reverse blades "The blade edge was just a couple of millimeter higher when reversed"
I thought reversing a blade is a design no no ,the blades work like a boomerang creating an upward lift
if you reverse the blades the air flow will push the grass down making cutting more difficult..
But I see what you mean by the cutting of high grass the air flow may have minimal effect at pushing the grass down.
If there is no reference to reversible blades I think the air flow problem is why.
I think I did see one vintage American mower with this type of blade.
Cheers
Max
