Cub Cadet PRO Z 772 L Operation Manual - Page 21

OPERATION • Shut engine off and remove the key. • Doing so will minimize the possibility of having your lawn ''browned'' by hot exhaust from your mower's running engine. 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 where 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 exceeds 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.

Inner Baffle: The inner baffle regulates grass discharge. Remove the inner baffle for high-volume grass and install the inner baffle for precision cutting. Discharge Baffle: The discharge baffle enhances the grass discharge pattern. The discharge baffle reduces clumping and should be removed for mulching. Cutting Blades: The cutting blades cut grass, create grass lift and discharge grass through the discharge chute. Gauge Wheels: The gauge wheels reduce scalping, help with precision cutting and reduce turf defacement during turns. Front Roller (if equipped): The front roller reduces scalping, helps with precision cutting and reduces turf defacement during turns. Rear Rollers: The rear rollers reduce scalping and gives grass a striped appearance. NOTE: To avoid damaging grass, no more than 1/3 of the grass height should be removed during a single cutting (i.e. if the grass is 6" tall, cut it to 4"). 21
