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. 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 sys- tems. More horsepower is required for these blades when compared to others, and they generally pro- duce 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 generally produce the lowest noise levels. Bahia blades are configured without offset, and with a maximum amount of sharp- ened 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 turbu- lence in order that the grass can be repeatedly cut and re-cut into smaller pieces. These blades gener- ally 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.

MAINTENANCE AND

SERVICE

WARNING:

Disconnect the spark plug wires or remove the key from the ignition to prevent the engine from accidentally starting before performing any maintenance on this mower.

A. Mower Deck

1.Removing the Mower Deck:

a.Apply the parking brake. Remove ignition key and both spark plug caps.

b.Lower the cutter deck to the ground. Cap- ture the foot pedal by placing the height of cut clevis pin in the “lock” position.

c.Remove tension of the PTO belt by moving the belt tensioning rod.

Note: There is a certain amount of spring tension due to the weight of the deck. When removing the lift linkage from the deck the ten- sion of the springs will go from the deck to the foot pedal. Not capturing the foot pedal while removing the lift linkage from the deck will cause it to snap back.

d.Detach the mower drive belt.

e.Remove six linchpins (See Fig. 6) (4) from the deck and (2) from the front of the mower. Remove the linchpins on the left and right rear side of the cutter deck (2);
