Ryobi Ryobi RY401110 40V HP Brushless 21 in. CrossCut Push Mower MULCHING POOR Error Fix: Poor Mulching or Bagging Performance

Error code MULCHING POOR on the Ryobi Ryobi RY401110 40V HP Brushless 21 in. CrossCut Push Mower means: Poor Mulching or Bagging Performance. The mower does not mulch clippings finely enough (large clumps left on lawn), or the grass bag fills slowly or clippings are not reaching the bag. For mulching issues: Install the mulching plug if not already installed — mulching requires the discharge chute to be blocked so clippings recirculate under the deck for additional cutting. Sharpen the blade — dull blades cannot finely chop clippings. Mow when grass is dry — wet grass clumps together instead of being finely mulched. Do not remove more than one-third of the grass height in a single pass. For bagging issues: Check that the bag is properly installed and the discharge chute flap is open. Empty the bag before it is completely full — an overfull bag restricts airflow and reduces collection efficiency. Check for clippings clogging the discharge chute opening — scrape built-up grass from the chute. A dull blade also reduces bagging performance because it does not generate sufficient airflow (lift) under the deck to propel clippings into the bag.
