A: Hi Tina, a fully charged battery is a great start, but if the mower is not turning on there are a few common things to check that can prevent startup. First, make sure the battery is fully seated and locked into place, if it is not clicked in securely, the mower will not receive power. Next, check that the safety key (if your model uses one) is inserted properly, as the mower will not start without it. For starting, press and hold the start button, then pull the safety handle (bail) toward the handlebar at the same time, both steps need to happen together for the motor to engage. It is also a good idea to inspect the battery terminals and mower contacts to ensure they are clean and free of debris or moisture. If the mower was recently used or stored in a hot or cold environment, allow both the battery and unit to return to normal temperature before trying again, as built-in protection systems can temporarily prevent operation. Lastly, check underneath the mower (with the battery removed) to make sure the blade area is clear of any grass buildup or obstructions, as this can trigger a safety shutdown. For a step-by-step setup, this Greenworks Tools video may help (https://youtu.be/vnNhjmgEX3U). If you have gone through these steps and the mower still will notstart, the issue may require further inspection.

A: Hi BOB the mower. Thank you for your interest. No. Greenworks batteries are interchangeable among products within that same voltage platform. This mean a 40V mower would require a 40V battery, any other voltage will not operate the unit. This unit can use any amp-hour sized Greenworks 40V battery. We hope this information helped!

A: Hello, thank you for your question. Yes, the blades should come ready to use.

A: Hello MrsK. Thank you for your inquiry! This unit has a runtime of up to 1/3 acre, or approximately 40 minutes with the included 40V ~ 4Ah battery. Actual runtime may vary based on factors such as terrain, grass height and type, mulching, and the operator’s technique.

A: Hello Darlene. Mower yard size range: less than 1 acre. Runtime range can fluctuate depending on terrain, grass height, grass type, mulching, and operators’ technique etc.

A: Hi Linda. Thank you for your interest. This mower offers the mulching feature, however there is no self-propelled feature. We hope this helped!

A: Hello Battery size - Each voltage line (24V, 40V, 60V, 80V, and 82V) has a set of tools that are only interchangeable within their own voltage platform. Greenworks 40V units are compatible with all Greenworks 40V GMAX, Max, and Elite battery models found in the USA.

A: Hello Carolyn69 - Runtime: Up to 45 minutes of run-time with fully charged 4.0 Ah USB battery (Run-times varies based on grass conditions and operator’s technique.) Charge Time: 120m per 40V battery (4.0 Ah battery). There are many possible scenarios that can affect the lifespan of a battery. In ideal conditions the battery has a charge and discharge cycle of up to 2000. This is a lithium-ion battery and does not degrade during storage.

A: Hello kcmow - All Greenworks 40V ~GMAX machines are compatible and interchangeable with all Greenworks 40V ~GMAX batteries and charger. Please note, only Greenworks batteries, chargers and machines of the same voltage are compatible and interchangeable with one another.

A: Hello rlunford1 - This unit is a push mower.
