Mower —The mower consists of two functional sections: the traction unit and
the mowing components. The mowing components consist of the carrier frames,
lift arms, cutting units and cutting unit drives.
Lift Arm — The lift arm is a structural unit which lifts and lowers the cutting
unit.
Carrier Frame —The carrier frame connects the lift arm to the cutting unit and
allows the cutting unit to pivot and follow ground contours.
Cutting Unit — The cutting unit consists of a reel, front and rear rollers, a
bedbar/bedknife assembly, and related adjusting mechanisms.
Cutting Unit Drive —Power for the cutting unit is provided by a belt and
pulley system, hydraulic motor, electric motor, or ground driven wheels.
Reel — The reel consists of varying numbers of helix-shaped blades. The blades
are attached to support spiders which are mounted on a rotating shaft. The reel
contacts the bedknife to perform a scissors-like cutting action.
