Abstract: A foliage mowing apparatus and mowing reel assemblies include a plurality of helically shaped blades which are mounted circumferentially with respect to each other. Each blade has a chevron-type junction or apex lying within a radially extending plain which is transverse to the longitudinal axis of the reel. Apexes of adjacent blades do not lie along the same radial plane. Instead, each apex is axially spaced from each of its adjacent apexes. With this structure, if a piece or blade of grass passes uncut through an apex area, a straight blade section follows immediately in order to cut or trim this piece or blade of grass.

Abstract: A mechanism for use in a reel type lawn mower for maintaining a controlled constant uniform pressure between V-shaped reel blades and a bedknife. The blades are arranged to maintain continuous contact with the bedknife on both sides of the center of the reel. A biasing unit acts between the reel unit and the bedknife unit to apply a regulated pressure on both sides of the reel center in response to a feedback signal such as a temperature signal at the reel/bedknife interface.
