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 generally produce the lowest noise levels. Bahia 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.

F.Cooling System

This product is equipped with a cooling system employing state-of-the-art technology. A 12VDC pow- ered fan draws air “upward” through a high efficiency multi-pass heat exchanger for about 10 minutes, then stops, runs in the “downward” direction for about 1 minute. Except for engine starting when the fan does not run for the first minute, the fan blows downward (to clear debris on the inlet screen) for about 1 minute, then upward for about 10 minutes...this 1 and 10 minute cycle repeats until the engine is shut off. The heat exchanger is mounted at an angle so that the heat will be blown away from the operator station. The heat exchanger can

be unlatched, pivoted upward, and secured via a prop- rod for access to the engine, etc.

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 main- tenance 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. Capture the foot pedal by placing the height of cut cle- vis 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 ten- sion due to the weight of the deck. When remov- ing the lift linkage from the deck the tension of the springs will go from the deck to the lift handle.

Not capturing the lift handle 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
