Cut and collect grass clippings in the 60 litre collector with fill level indicator so you know when it needs emptying. Rear discharge allows the clippings to be ejected through the rear of the machine where they can be left to wilt back naturally. The side discharge option ejects the cuttings through the side of the mower and leaves them in neat rows whilst you mow. Mulching is a particularly beneficial option, especially in hotter, drier conditions. Mulching cuts the clippings into tiny pieces and blows them back onto the lawn where they become barely visible. They then provide your lawn with additional nutrients and moisture which promote healthier regrowth. 7 cutting height positions ranging through 30 80mm can be easily selected using the lever. Start at the highest and work your way down to get the best cut and finish to your lawn. features60 litre easy click rigid grass collector has been designed for optimum airflow which improves the filling performance.
