Product Information

Full details

The Garden Master 40V Cordless Lawn Mower is designed for homeowners with small to medium-sized lawns who want the convenience of cordless mobility without sacrificing power. Its primary benefit is the efficient brushless motor paired with dual 20V 4Ah batteries, which provides long run times and consistent performance. However, users should note that as a battery-operated tool, it requires regular charging cycles and may not be suitable for expansive professional-grade meadows.

FAQs

Can I use the mower with only one battery?

No, this model requires both batteries to be installed to provide the necessary 40V power to the brushless motor.

How long do the batteries take to charge?

Charging time depends on the state of discharge, but the provided double charger is optimized for standard 4Ah battery recovery.

Is this mower suitable for wet grass?

It is recommended to mow dry grass for optimal performance and to prevent clogging in the collection chute.

Are the batteries compatible with my other tools?

Yes, the 20V batteries are interchangeable with other Garden Master products in the same voltage family.

How do I know when the grass box is full?

The mower includes an auto-full indicator located on the collection box that signals when capacity has been reached.

Troubleshooting

Mower fails to start

Ensure both batteries are fully charged and securely clicked into their respective slots. Check the safety key is inserted properly.

Motor stops during operation

The grass may be too long or wet. Raise the cutting height and move at a slower pace to avoid overloading the motor.

Uneven cut

Check if the blade is damaged or loose. Also, ensure the height adjustment lever is fully engaged in one of the five settings.
