Three (3) types of reel designs are used in Reelmaster cutting units: scalloped
radial reel, tapered radial reel and tapered forward swept reel
radial reel designs have blades that are placed in line with the center of the reel
shaft. The rear of the blades either have a scalloped relief or a tapered relief.
The forward swept reel have blades that have a slight forward slant. The rear
of the forward swept reel blades have a tapered relief. Before grinding a reel,
identify the type of reel design to make sure that grinding is correctly done.
Before grinding a cutting reel, make sure that all cutting unit components
are in good condition. Depending on type of grinder used, faulty cutting unit
components can affect grinding results. When grinding, be careful to not
overheat the cutting reel blades. Remove small amounts of material with each
pass of the grinder.
