6 Best Alternatives to the EARTHQUAKE Walk Behind String Mower (2026)

How these alternatives compare

PowerSmart 22-Inch 170cc Self-Propelled Gas Mower Kit

This PowerSmart kit includes a 170cc gas engine, which is slightly larger than the Earthquake’s 160cc motor. It offers a 22-inch cutting width, matching the original exactly. Unlike the Earthquake’s string trimmer head, this unit uses a traditional mower deck for grass. It adds a dedicated trimmer attachment, expanding your toolset for brush. The self-propelled drive helps with large yards, whereas the Earthquake is a push model. You gain versatility by handling both mowing and edging with one purchase. It is heavier and longer than the Earthquake, so storage requires more space. Choose this if you need a complete yard care system rather than just a trimmer.

Greenworks 40V 21-Inch Self-Propelled Mower

The Greenworks 40V model shifts from gas to a 40-volt battery system. It features a 21-inch cutting deck, one inch narrower than the Earthquake’s 22-inch string path. This unit is self-propelled, removing the physical effort of pushing compared to the Earthquake’s manual operation. It weighs 73.9 pounds, similar to the Earthquake’s 70 pounds. You get quieter operation and zero emissions, but you lose the ability to run indefinitely without recharging. The battery capacity is 5.0 Ah, providing runtime for medium-sized lawns. LED lights improve visibility in low light. Pick this if you prefer electric power and self-propulsion over gas durability and wider cuts.

Greenworks 60V 21-Inch Self-Propelled Mower

This Greenworks 60V mower uses a higher voltage battery platform than the 40V model. It also has a 21-inch cutting width, slightly narrower than the Earthquake’s 22-inch reach. The self-propelled drive system assists you on slopes, unlike the Earthquake’s push design. It weighs 65 pounds, making it lighter than the Earthquake. The 4.0 Ah battery offers less capacity than the 5.0 Ah version, but the 60V system provides more power. It includes a 4-in-1 deck for mulching, bagging, or side discharge. You trade the string trimmer’s unique reach under fences for a traditional mower deck. Select this for quiet, self-propelled mowing on medium lawns without the maintenance of a gas engine.

EGO Power+ 21-Inch 56V Cordless Push Mower

The EGO Power+ model operates on a 56-volt battery system with a 4.0 Ah capacity. It has a 21-inch cutting width, one inch less than the Earthquake. This is a push mower, so you must provide the forward motion, similar to the Earthquake. It weighs no listed amount, but the build feels robust for flat lawns. The 56V system offers high torque for thick grass. LED lights enhance visibility during early morning or evening cuts. You give up the string trimmer’s ability to clear wide debris paths and reach under low obstacles. Instead, you gain a durable, quiet electric mower. Choose this if you want high-torque electric power and do not mind pushing the unit on flat terrain.

PowerSmart 18-Inch 144cc Gas Push Mower

This PowerSmart unit features a 144cc gas engine, slightly smaller than the Earthquake’s 160cc motor. It has an 18-inch cutting width, significantly narrower than the Earthquake’s 22-inch reach. This makes it ideal for small yards and tight spaces where the Earthquake might be too wide. It is a push mower, requiring manual effort. The deck is designed for side discharge, simplifying cleanup. It weighs 58.4 pounds, lighter than the Earthquake. The compact size allows for easier storage and maneuverability around obstacles. You lose the wide cutting swath and the string trimmer’s unique debris clearing capability. Pick this if you prioritize maneuverability in tight spaces over the broader coverage of the Earthquake.

Greenworks 80V 21-Inch Cordless Push Mower

The Greenworks 80V model uses a high-voltage battery system for powerful cutting. It has a 21-inch cutting width, one inch narrower than the Earthquake. This is a push mower, so you handle the forward motion yourself. It weighs 74.1 pounds, slightly heavier than the Earthquake. The 80V system delivers strong performance for small lawns. It excels at mulching, keeping your lawn tidy without bagging. You give up the string trimmer’s ability to clear wide paths and reach under low fences. Instead, you get a quiet, efficient mulching mower. Choose this if you have a small lawn and prioritize quiet operation and mulching over the wide, versatile cutting of the Earthquake.
