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.

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. cap screw and nut from FIXED position (C). Install
1/2 x 3 in. cap screw if not done so already. Cap screw (B) can remain in place, it is (C) that has to be removed depending on mowing conditions.

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

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

Grass Deflector


M56238

The cutting units come with a grass deflector mounted on the rear of the cutting units.

NOTE: For ease of changing, the bent end of rod (A) should be located opposite the motor end of the cutting units.
