Reel Mowers
13
Factors that affect the clip rate:
•
•
•
•
Diameter of reel
Number of blades
Speed of reel
Ground speed
The ideal situation is when H.O.C. = Clip Rate
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
