Hello Boise mower man,

Thank you for taking the time to leave a review. We are sorry to hear you are experiencing shorter than normal runtime.

For best results users should:

1) Mow when the grass is dry.

2) Mow in the morning or late afternoon to reduce the heat stress on the newly cut grass.

3) Alternate mowing patterns each time you mow. As grass develops a grain based on your cutting direction it will lean towards the direction of your mowing path. Changing the pattern allows better vertical growth and helps to keep the cut neater.

4) Consider mulching. To mulch, remove the bag and insert the mulch plug into the rear of the unit. This will leave the clippings on the lawn allowing the nutrients and nitrogen contained within them to return to the soil and allow the remaining grass to recycle them (always discharge the mulch towards a previously cut area to prevent your mower from bogging down).

5) Always keep in mind what conditions your variety of grass prefers. If your grass prefers cooler climates, reduce the frequency with which you mow and increase the cutting height of your mower during hot seasons to compensate for the reduced growth rate these varieties may experience in this type of weather.

6) Make sure the battery is cool before use. When the battery will not be in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging.

Lastly it is worth noting, lawn mower that provides more than one battery ports; it is recommend using all batteries for optimal runtime. This unit requires all six (6) batteries for optimal runtimes.

We hope these tips will help! If not, we would be happy to investigate to see whether your run time would be considered average, please contact Greenworks Solution Service Team at 1-877-481-6087. All we ask that you have access to the unit so that we can complete troubleshooting with you and gather necessary unit information.
