Reel Mowers 13

Factors that affect the clip rate:
The ideal situation is when H.O.C. = Clip Rate
• Diameter of reel
• Number of blades
• Speed of reel
• Ground speed
If we observe multiple clips we get a series of triangles set side by side.
The top of the triangle represents the individual shear point.
The clip rate is therefore, the distance between the tips of the triangles.
The clip rate is critical to the appearance of the cut. Ideally, the clip rate should equal the height of cut.
Factors that affect the Clip Rate are listed in the illustration.
Generally, the lower the height of cut, the more blades are required, or the reel must rotate at a faster speed
to keep the clip range in sync. A greens mower cutting unit, for example, may be available with 8, 11, or even
14 blade cutting units.
Most cutting units have a preferred operating range and all cutting units can be adjusted beyond that
preferred range. Choose a cutting unit where the intended height of cut is in the middle of the height of cut
range
