Nut (5/16 inch)—48-inch decks only | 3 |
Nut (5/16 inch)—54-inch and 60-inch decks only | 4 |
Install the left baffle as follows:
For 48-inch decks, install the left baffle using 3 nuts (5/16 inch) and 1 carriage bolt (5/16 x 3/4 inch) as shown in Figure 14.
For 54-inch and 60-inch decks, remove the existing fasteners from the holes shown in Figure 15, and install the left baffle using 4 nuts (5/16 inch) and 1 carriage bolt (5/16 x 3/4 inch).
Tighten all fasteners.
Parts needed for this procedure:
Decal | 1 |
Mulching blades | 3 |
Install the decal to the mower deck in the location shown in Figure 16.
Install the mulching blades on machine; refer to the Operator’s Manual for the machine.
For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height of cut so low as to totally surround the mower in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.
Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, cut the lawn twice to ensure an acceptable quality of cut.
Cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.
Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
To improve cut quality, use a slower ground speed in certain conditions.
When mowing uneven turf, raise the cutting height to avoid scalping the turf.
If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward.
Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the mower blades after each use for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
