Why We Recommend It
- 01.
60V / 4Ah battery system operates at 57% higher voltage than the database average of 38.1V, translating to stronger cutting performance in thicker grass
- 02.
22-inch cutting deck is wider than the 18-inch walk-behind average , covers more ground per pass for faster mowing sessions
- 03.
90-minute total runtime (two 4Ah batteries included) far exceeds the average battery mower runtime of 52.7 minutes
- 04.
14-inch never-go-flat wheels front and rear provide stable, consistent rolling across uneven turf without tire maintenance worries
- 05.
Push-button start and zero fuel, oil, or spark plug maintenance makes it far simpler to own and operate than a comparable gas string mower
Considerations
- 01.
Push mower only , no self-propelled drive, so larger or sloped yards will require more physical effort from the operator
- 02.
At 40 lbs, it's manageable but not the lightest option; users who want to minimize fatigue over long sessions may notice the weight
- 03.

Power & Performance
The 60V battery platform is the standout power spec here , at nearly 60% higher voltage than the average battery-powered walk-behind in this category, it produces more torque through the cutting blade, which matters when tackling dense or slightly overgrown grass. The three-speed cutting dial gives you control over motor output so you can conserve battery life on thin grass or dial up for thicker patches.
While there's no brushless motor explicitly listed in the spec sheet, the 60V architecture generally supports strong consistent power delivery across the full cutting session.
Cutting System
The 22-inch composite deck is a meaningful upgrade over the 18-inch industry average , that's roughly 22% more cutting surface per pass, which adds up to noticeably fewer back-and-forth runs across your lawn. The rotary blade design handles standard residential turf well across varying grass types.
Cutting height is adjustable via the handlebar-integrated or deck-mounted system (verify your preferred height range before purchase), and the string trimmer cutting mechanism is well-suited for edging close to obstacles where a blade mower would struggle.
Drive & Handling
This is a push mower, so all forward motion comes from the operator. At 40 lbs, it's within the typical range for battery walk-behinds and manageable for most adults on flat to gently rolling terrain.
The adjustable handlebar accommodates different operator heights, reducing fatigue over longer mowing sessions. The 14-inch never-go-flat wheels on all four corners roll smoothly over turf irregularities and eliminate the hassle of checking tire pressure , a small but practical advantage over pneumatic-wheeled models.
Battery / Fuel
Two 60V 4Ah batteries are included along with a charger , this is a notable value addition since many competitors sell batteries separately. Each battery contributes to the combined 90-minute runtime rating, which is among a strong option for in the cordless walk-behind category (database average: 52.7 minutes).
Battery swaps are simple when one depletes mid-session. Unlike a gas string mower, there's no exhaust, no fuel to store, and no seasonal maintenance , just charge and go.
Recharge time isn't specified in available data, so confirm with the manufacturer if turnaround time between sessions matters to your workflow.
Who Is This Mower For?
Ideal For
- ✓ Medium to large flat yard owners (1/4 to 1/2 acre) who want a single charge to cover the whole lawn , the 90-minute runtime and 22-inch cut path make this viable without swapping batteries mid-session
- ✓ Eco-conscious homeowners switching away from gas string mowers , zero direct emissions, no exhaust fumes, and a quieter operating experience without sacrificing cutting width
- ✓ Low-maintenance seekers who want to skip oil changes, fuel stabilizers, carburetor clogs, and pull-cord frustration that come with gas alternatives
- ✓ Users who want an out-of-the-box ready mower , no assembly required means you can start mowing the same day it arrives
Not Ideal For
- ✕ Hilly or steep terrain owners , the push-only design means you're providing all the forward force on inclines, which becomes physically demanding quickly
- ✕ Very large property owners (1+ acre) who need extended continuous runtime; even with two 4Ah batteries, you may need a charging break mid-mow on bigger lots
- ✕ Users who prioritize ultra-lightweight equipment , at 40 lbs, this is not the lightest cordless option if physical ease is the top priority
Earthquake states no assembly is required for this model, meaning it arrives ready to use straight out of the box. Charge the included 4Ah batteries, adjust the handlebar to your height, and you're ready to mow.
Fully charge both 4Ah batteries before first use to ensure maximum runtime and condition the battery cells
Set the handlebar height before your first mow , the adjustable design means a few seconds of setup will prevent back strain over longer sessions
Warranty details for the Earthquake 44965 are not included in the available product data. Earthquake is an established outdoor power equipment brand , verify current warranty terms directly with the manufacturer or retailer before purchase, particularly coverage for the battery cells and motor, as these are the highest-value components.
FAQ
Does the Earthquake 44965 come with batteries, or do I have to buy them separately?
Yes , two 60V 4Ah batteries and a charger are all included in the box. This is a meaningful value add since replacement or extra 60V batteries can investment -+ each when purchased separately.
You get everything needed to start mowing immediately after charging.
How long does the battery last on a single charge, and can I mow a 1/2 acre lot on one set?
Earthquake rates the two included 4Ah batteries at a combined 90 minutes of runtime, which is well above average for cordless walk-behinds. A 1/2 acre lot typically takes 45-60 minutes to mow depending on pace and obstacles, so a full charge on both batteries should cover it with runtime to spare.
Thick or overgrown grass will draw more power and reduce total battery life per session.
Is this mower self-propelled, or do I have to push it myself?
The Earthquake 44965 is a push mower , there is no self-propelled drive system. You provide all the forward force.
At 40 lbs with 14-inch wheels, it rolls reasonably well on flat to gently rolling terrain, but users with significant slopes should factor in the physical effort of pushing uphill.
How does the 60V system compare to other battery mowers , is it actually more powerful?
The 60V platform operates at significantly higher voltage than the battery mower average of around 38V in this category, which generally translates to more torque and better performance in dense or slightly tall grass. The three-speed dial also lets you manage how aggressively the motor runs, balancing power output against battery life based on your lawn conditions.
What are the wheels like, and do they handle uneven ground well?
All four wheels are 14-inch never-go-flat units , larger than typical and solid-fill so they never need air. This makes them more reliable over time than pneumatic alternatives and they roll smoothly over small ruts, roots, and turf irregularities.
The 14-inch diameter also helps maintain momentum and reduces effort when pushing across longer stretches of lawn.
How does maintenance on this compare to a gas string mower?
Maintenance is dramatically simpler than a gas string mower. There's no oil to change, no spark plugs to replace, no exhaust buildup, no carburetor to clean, and no fuel stabilizer needed during off-season storage.
Battery care is the primary maintenance consideration , store batteries at partial charge in a cool, dry space during winter and avoid fully depleting them regularly to maximize long-term battery life.
Bottom Line
The Earthquake 44965 is one of the more capable battery-powered walk-behind string mowers available, combining a wide 22-inch cutting deck, a high-voltage 60V system, and dual included 4Ah batteries for 90 minutes of runtime , all with no assembly required and zero maintenance compared to gas alternatives. It's an excellent fit for flat-to-moderate medium and large yards where the push design isn't a drawback.
Those with steep hills or very large properties should weigh the push-only limitation carefully.
Best for flat to gently rolling medium yards (1/4 to 1/2 acre) where owners want a powerful, low-maintenance battery mower with generous runtime and wide cutting coverage.
Consider alternatives if you have steep terrain requiring self-propelled assist, or a property over 3/4 acre where even 90 minutes of runtime may not be enough for a single uninterrupted session.
