Check Ground Conditions


MIF

ˇ Clear mowing area of objects that might be thrown. Keep people out of mowing area.

ˇ Study mowing area. Set up safe mowing pattern. Do not mow under conditions where traction or stability is doubtful.

Avoid Injury From Contacting Blades


MIF

Before you dismount to unplug or adjust cutting units:

ˇ DISENGAGE reel drive by moving PTO switch to OFF position.

ˇ STOP the engine.

ˇ LOCK the park brake.

ˇ Remove key.

ˇ Wait for reels to STOP.

Keep hands, feet and clothing away from cutting units when engine is running.

DISENGAGE reel drive by turning PTO switch to OFF position when you are not mowing.

Cutting Taller Grass (Front Rollers Are Optional)

IMPORTANT: Avoid damage! When mowing tall grass in rough terrain, it is recommended to leave the front rollers on to protect the reels from striking any unseen objects.


When cutting grass taller than approximately 38 mm (1-1/2 in.), the front roller tends to knock down grass affecting the quality of cut. In these conditions, it may be necessary to operate with cutting units in fixed position without a roller.

NOTE: The fixed position is recommended for smooth areas only, such as athletic fields, level parks, etc.

1. Remove front roller (A).

2. Remove scraper, if equipped.


M56202

3. Install 1/2 x 1 in. cap screw, and nut, from bag of hardware supplied with machine, to fixed position (B) on both sides of all three cutting units.

Cutting Shorter Grass

When cutting grass under approximately 38 mm (1-1/2 in.) Place the cutting unit in the floating position.


M56207

1. Install front roller (A).

2. Install scraper, if equipped. (See instruction sheet provided for scraper kit).


M56203

3. Remove 1/2 x 1 in. capscrew and nut from fixed position (B).

NOTE: Cutting grass under 38 mm (1-1/2 in.) in dry conditions a grooved roller may be desirable.

In wet/muddy conditions or in new growth areas a smooth roller may be the choice.

Grass Deflector
