Hello Troyjan. Thank you for taking the time to share your experience and review! It is important to recognize that the run time depends on the load acting against the unit and fluctuates depending on the height setting, the terrain, grass height, type of grass, whether you are mulching, operator technique, etc. - there are so many factors to consider. The harder the unit will work, the quicker the battery charge will drain. Like how the gas in a vehicle will deplete quicker when driving at higher speeds or carrying more weight. As the lawn becomes consistently maintained you will see the cut and runtime improve. New mower blades often have a protective coating applied to them. This coating helps prevent rust and corrosion during storage and transportation, especially if the blades are stored in environments with high humidity or where they might come into contact with moisture This is a common characteristic of many new mower blades, including those from Greenworks. Sharpening or replacing blades is recommended at least once a season, or more frequently if needed, as a dull blade can lead to ragged cuts and other lawn issues.
