STIGA Alpina Mulching Kit Instruction Manual

1. Introducció

This manual provides instructions for the proper installation, operation, and maintenance of the STIGA Alpina Mulching Kit. This kit is designed to convert your ride-on mower (models BT 66, AT1 66, AT1 66 HCB) for mulching operations, allowing grass clippings to be finely cut and returned to the lawn as natural fertilizer. Please read these instructions carefully before installation and use to ensure safe and efficient operation.

2. Lift the discharge chute cover.
3. Insert the mulching plug firmly into the discharge opening, ensuring a snug fit. The plug should block the opening completely.
4. Lower the discharge chute cover. Ensure it closes securely over the mulching plug.

2.3 Blade Installation (If applicable)

Some mulching kits include specialized mulching blades. If your kit includes new blades, follow these steps. Otherwise, proceed to Section 2.4.

1. Carefully tilt the mower or lift it using a suitable jack to access the underside of the deck. Ensure the mower is stable and cannot tip.
2. Using a wrench, remove the blade retaining bolt and washer. Note the orientation of the existing blade.
3. Traieu la fulla antiga.
4. Install the new mulching blade, ensuring the cutting edge faces the correct direction (usually indicated by an arrow or "Grass Side" marking).

Important: Refer to your ride-on mower's primary instruction manual for specific blade removal and installation procedures and torque specifications.

3. Operating the Mulching Function

For optimal mulching results, follow these guidelines:

• Cut Dry Grass: Mulching works best on dry grass. Wet grass tends to clump and can clog the deck.
• Cut Frequently: For best results, cut grass frequently, removing no more than one-third of the grass blade length at a time. This ensures smaller clippings that decompose quickly.
• Velocitat del motor: Operate the mower at full throttle to ensure maximum blade tip speed for effective cutting and recirculation of clippings.
• Altura de tall: Adjust the cutting height to suit grass conditions. Taller grass may require a higher cutting setting or multiple passes.
• Passades superposades: Overlap each mowing pass slightly to ensure even coverage and prevent missed strips.
• Avoid Excessive Growth: If grass is excessively long, consider bagging or side-discharging first, then mulching the shorter clippings on a second pass.

4. Manteniment

Regular maintenance of your mulching kit ensures its longevity and optimal performance.

• Neteja la coberta: After each use, especially when mulching, clean the underside of the mower deck to remove accumulated grass clippings. This prevents rust and maintains airflow for effective mulching.
• Inspect Mulching Plug: Periodically check the mulching plug for damage, cracks, or wear. Replace if necessary to maintain a proper seal.
• Esmolat/Substitució de fulles: If using specialized mulching blades, ensure they are kept sharp. Dull blades tear grass, leading to an unhealthy lawn and poor mulching performance. Sharpen or replace blades as needed, following your mower's manual.
• Emmagatzematge: When not in use for extended periods, store the mulching kit components in a clean, dry place.
