The 40V push mower from Greenworks provides a lighter option with a 19″ steel deck for efficient coverage of larger yard areas. The mower uses a brushless motor for improved torque, quieter operation, and longer life. A 4.0Ah battery extends run time, and the 7-position single-lever height adjustment ensures precise cut levels across varied terrain. The 2-in-1 design allows mulching or side discharge of clippings for flexible maintenance.
LawnMaster CLMF4819X 19-Inch

Buying Guide
When selecting a side discharge electric mower, consider these factors to balance performance with yard size and storage needs:
- Battery System and Runtime: Higher voltage generally means more torque and longer runtime. Look for mowers with 60V–80V systems or dual-battery setups for extended lawns.
- Deck Size and Cut Width: A larger deck covers more ground per pass. For bigger lawns, 21″ decks are common, while 19″ decks suit compact storage spaces.
- Self-Propelled vs. Push: Self-propelled models reduce effort on uneven or hilly terrain. Check speed settings to match your pace.
- Discharge and Mulch Options: Side discharge is convenient for tall or thick clippings; mulching capability helps return nutrients to the lawn.
- Maintenance and Durability: Brushless motors offer longer life and quieter operation. Look for steel decks for durability and longevity.
- Accessory Ecosystem: A mower compatible with a broader line of tools can be cost-effective if you already use a particular brand.
- Storage and Portability: Foldable handles and compact designs simplify storage in smaller spaces.
For choosing among the options, compare runtime under typical mowing conditions, the weight for maneuverability, and the availability of headlights for early morning or late evening sessions. Real-world performance varies with grass type, moisture, and operator technique, so selecting a model with a flexible power system and good warranty coverage can improve long-term satisfaction.
