The hovers only leave a "snail trail" when the grass collector bin starts
getting full, or the blades start getting clogged with wet grass.

In dry grass cutting conditions, say mid-summer, none of that would apply
providing the collector is cleared.

makes them *really* terrible, and clearly if the collector is full, it is
difficult for them to do anything but spill
