Using a Mulching Mower

Benefits of Proper Mulching

Mulching consists of a mower deck which cuts and recuts clippings into tiny particles and then blows them down into the lawn. These tiny particles decompose rapidly into by-products that your lawn can use. Under proper conditions your mulching mower virtually eliminate noticeable clippings on the lawn surface.

Limitations of Mulching Decks

Mulching mowers cannot function properly if the grass is wet, or if the grass is simply too high. Even more than normal mowing, mulching requires that the grass be dry and that no more than 1/3 of the height is cut.

Do not use the mower as a mulching mower during the first two or three cuttings in the spring. The long grass blades, quick growth, and often wetter conditions are more suitable for broadcasting (side-discharging).

Correct Ground Speed & Engine Speed

Use full engine throttle to maximize mower blade tip speed matched with a slow ground speed so that clippings will be finely cut. Ground speed while mulching should be half the speed used when broadcasting (side- discharging) under similar conditions. Since mulching requires more horse power than broadcasting, using a proper ground speed is vitally important for good mulching operation.

Correct Cutting Height

Cutting off too much at one time shocks the plant’s growth system and weakens the grass. A good rule of thumb is the 1/3 rule: to cut no more than one third of the grass height, and never more than 1 inch (2,5cm) at a time.

The best mulching action typically results from cutting only the top 1/2” to 3/4” (1,25 - 2cm) of the grass blade. This provides short clippings which decompose properly (much more quickly than longer clippings). The ideal cutting height will vary with climate, time of year, and quality of your lawn. We recommend that you experiment with both the cutting height and ground speed to achieve the best cut. Start with a high cutting height and use progressively lower heights until you find a cutting height that is matched to your mowing conditions and preferences. For best results, overlapping is recommended.

Using the Side Discharge Deflector

When to use the side discharge deflector: If you’ve been on vacation or missed a mowing and the grass has gotten very long, do not try to mulch at your normal cutting height. To handle these situations your mulching mower is equipped with a side discharge deflector. Installing the side discharge deflector allows you to broadcast clippings. Broadcasting, or side-discharging, disperses fine clippings evenly over the entire lawn. Always operate the engine at full throttle. Use an appropriate ground speed for the thickness and height of grass you are cutting. If you hear the engine slowing down, you are mowing too fast, use a slower ground speed. Mow when the grass is 3”-5”(7,6-12,7cm) long. Do not cut off more than 1” (2,5cm) in a single pass.

WARNING

Never operate the mower deck without either the discharge chute or mulching deflector in place.

To install the side discharge chute:

1.Lift up the mulching cover (B, Figure 15).

2.Install the side discharge deflector (A) under the mulching cover. The side discharge deflector hooks onto the mulching cover hinge rod, and is held in place by the mulching cover.

3.Release the mulching cover.
