A plug that blocks the chute, and sometimes a different blade

Mulching kits, compared

Mulching means cutting the clippings small enough that they fall back into the sward and rot there instead of being collected, and on most mowers it is done by blocking the discharge chute so the grass is recirculated under the deck until it is short enough to fall through. The part that does the blocking is a wedge — « Mulchkeil » in the German titles — and that is the simplest thing this shelf sells. The type column separates it from the other two forms. A full kit pairs the plug with a purpose-shaped blade whose curved wing keeps the clippings circulating, which mulches markedly better than a plug alone on a deck that was not designed for it. And a mulching blade sold on its own suits machines that already have a plug or a closed deck. The fits column is absolute here: a plug is a moulded shape that has to seal one particular chute, and the listings name single models — Makita 191D46-2, AL-KO Easy 4.60 SP-S, EGO LM1900E-SP — rather than families. A universal plug is a rubber flap and it works about as well as that sounds. The cutting width is quoted where a blade is included, because the blade has to match the deck exactly. The parts column says what is in the box — plug, blade, bolts, or all three — and it is the difference between a twenty-euro purchase and a sixty-euro one. Mulching returns nitrogen to the lawn and stops the ritual of emptying a box, at the cost of needing to cut more often and never in wet grass. We compare type, cutting width, fits, parts and material.
