The blade is able to cut the knocked down grass twice as it travels over it (front and back of blade path). When you are turning, the wheels knock down grass that is cut by the blade parallel to travel and the blade only has one shot to lift and cut it. Both factors lead to leaving grass around turns. The problem is exaggerated by dull blades or blades sharpened almost to the wing. These old decks don't have high lift blades. Mulching blades are about the only option for them, but I've read they don't do much for a better cut, just makes the clippings smaller.
FWIW, I only have the none cutting around corner issue when I make the initial 2 passes around my house and yard perimeter. The rest of the time I am going in straight lines back and forth, no turns to mow around. If you are starting on the outside and mow in circles till your done, it will give you the worst looking cut because your constantly mowing around corners.

I agree with all that.
When I used those older decks, I had the same problem whether the blades were sharp or dull. They don't like 90* corners.
In one of the Cub manuals, it shows how to mow corners. Go past the corner, turn the tractor around and hit the corner square on. That way you're not dragging the deck sideways over the grass.
I bought a set or two of those hardened blades. They'd last forever before getting dull compared to the standard blades. Very pricey though.
