Hard to believe there's no high lift blade available. What's the part number on the 3-in-1 blade?
Never mind - I get part number 942-04385 for the 3-in-1 and I can't find a high lift (2-in-1) for it either.
.I wonder, could a Snapper RER blade be adapted to fit? Might be worth looking into.
Give it a couple years and I'm sure there will be an aftermarket high lift for it.
