21″ (53 cm) Steel Cutting Deck: Durable steel construction stands up to regular use and provides a broad cut per pass for efficiency.
4-in-1 Cutting Options: Collect in the large bag, mulch back into the lawn, or eject from the side or rear depending on your preference and grass conditions.

Large Capacity Collector: 65 L grass bag means fewer stops and more mowing time.
Technical Specifications

For best results, mow when grass is dry and only remove a third of the blade length at a time — this reduces stress on the engine and gives a cleaner, more even finish. Make sure to check and empty the grass bag regularly to maintain airflow and cutting performance.
