Atomic Mulching: Blade has a toothed sail for mulching in discharge mode.
Recycler Blade: low lift blade ideal for mulching without discharge
Low sail blade: ideal for light turf conditions, sandy geographies and bagging dry leaves
Medium sail blade: ideal for side discharging or bagging in average conditions.
High sail blade: ideal for side discharging in dense, heavy conditions or bagging wet leaves
Toro-
Can it be concluded that the HIGH SAIL BLADE is backward compatible to cover HEAVY CONDITIONS and also AVERAGE CONDITIONS, or does it perform only in HEAVY CONDITIONS ?

...thank you.
