Mower Cutting Blades
The blades normally factory installed on a mower afford the best grass cutting performance on the
majority of grasses and mowing conditions; however, there will be occasions whereby the grass type,
stage of grass growth, soil conditions, and weather conditions will require different cutting blade types.
Since the mower decks are designed so that over-lap of the cutting blades generally exceed 1.5”, there
is no need for orientation of one cutting blade to an adjacent blade (i.e., the blades do not need to be
“timed” nor synchronized).
Hi-lift — These are generally the best cutting blades for most grasses and mowing conditions. The
Hi-Lift blades are the factory installed blades on these mowers. These blades will provide extra “lift” for
the thinner leaf grasses, will handle lush grasses, and will provide maximum grass and debris discharge.
These blades are generally required for material collection systems. More horsepower is required for
these blades when compared to others, and they generally produce the highest noise levels.
Medium-lift — These blades require less horsepower than the hi-lift, and they generally work well
in wider leaf grasses and some mulch applications.
Low-lift — These blades require less horsepower than hi-lift and medium-lift blades, and they generally work
best with wide leaf grasses, sparse grass growth, and sandy soil conditions. They produce the lowest noise levels.
Low-lift blades are configured without offset, and with a maximum amount of sharpened cutting edge.
Mulch — These blades are generally designed for use in cutting decks equipped with mulch baffles. The
shape of the blade generally produces higher turbulence in order that the grass can be repeatedly cut and re-cut
into smaller pieces. These blades generally require more horsepower than other blades. Mulch blades work best
when the grasses are cut at the highest levels, minimal lengths of grasses are removed, and grass conditions
are generally dry.
NOTE: Refer to the Attachment & Accessories section for a list of part numbers.
Table Notes: This table is a general outline of suggested settings, mowing conditions may vary.
*Inner Baffle (48, 54 and 60 inch Decks Only): The inner baffle (a) regulates grass
discharge. Remove the inner baffle for high-volume grass and install the inner baffle for precision
cutting (Figure 17).
Discharge Baffle: The discharge baffle (b) enhances the grass discharge pattern. The discharge
baffle reduces clumping and should be removed for mulching (Figure 17).
Cutting Blades: The cutting blades cut grass, create grass lift and discharge grass through the
discharge chute.
**Gauge Wheels (48, 54 and 60 inch Decks Only): The gauge wheels reduce
scalping, help with precision cutting and reduce turf defacement during turns.
Discharge Chute: The discharge chute controls the mower deck discharge and enhances the
discharge pattern
NOTE: To avoid damaging grass, no more than ⁄ of the grass height should be removed during a single
cutting (i.e. if the grass is 6” (15.2 cm) tall, cut it to 4” (10.2 cm).
