4.4 Mulching and Bagging Setup
Your mower offers 2-in-1 mowing versatility: mulching or rear bagging.

5.2 Mowing Techniques
For best results, mow in straight, overlapping lines. Avoid cutting more than one-third of the grass blade length at a time. If the grass is very tall, raise the cutting height and make two passes. The mower provides up to 60 minutes of runtime with a 4.0 Ah battery, depending on grass conditions.
