g'day bob,

just can't figure this one it matters not to the blades what engine is
turning them, i mowed lawns for years our 4 strokes cut neat they had
to, for rough cutting 2 blades is better for fine neat work 4 blades
is the go. and with the victa being the only common alternative 2
stroke i can safely say there are no reliable 2 strokes with
durability on the market place but then if the ground is that rough
and undulating there may be no choice.

but a speciaist shop should steer them right in the section.

snipped
With peace and brightest of blessings,

len
