Switching between collection or mulch modes is extremely simple and takes less than a minute. To mulch, just remove the collector, insert the mulching plug into the discharge chute and replace the collector. To return to collection, simply reverse the procedure.
Mulching the grass allows the clippings to be recycled, improving the soil as they decompose forming a natural fertiliser high in potash and nitrogen. You will notice a marked improvement in your grass as this fertiliser takes effect over the course of the cutting season.
