Greenworks MaximusZ Battery Life & Price: Is It Worth It?

How Long Does the Battery Last on the Greenworks MaximusZ?

Battery life is the biggest concern for any electric mower, and the MaximusZ is no exception. Greenworks equips it with a large 12kWh battery pack (roughly 120V, 100Ah), which they claim can mow up to 2.5 acres on a single charge. However, real-world tests show that this figure depends heavily on mowing conditions. On thick, damp grass or when using the variable-speed drive at higher settings, you might see closer to 1.5 to 2 acres.

For homeowners with lawns under 2 acres, the battery will likely handle the job in one session. But if you have a larger property, you'll need to plan for a recharge, which can take up to 2 hours with the included fast charger. That's a significant downtime compared to simply refilling a gas tank. Keep in mind that battery performance also degrades over time, so expect reduced runtime after a few years of heavy use.

How Much Does the Greenworks MaximusZ Cost?

The MaximusZ carries a hefty price tag of around $5,999, making it one of the most expensive electric riding mowers on the market. That's roughly double the cost of a comparable gas zero-turn mower from brands like Husqvarna or John Deere. However, you're paying for the advanced five-motor system, premium build, and the convenience of zero emissions.

When comparing costs, consider long-term savings: no gas, no oil changes, minimal maintenance, and potential federal tax credits for electric lawn equipment (up to 30% under the Inflation Reduction Act). Over 5-7 years, the total cost of ownership might come close to a gas mower, but the upfront investment is steep. Check our detailed buying guide for current pricing and any seasonal discounts.

Is the MaximusZ Worth the Price?

Whether the MaximusZ is worth it depends on your priorities. If you value a clean, quiet mowing experience and have a medium-sized lawn, the MaximusZ delivers excellent performance. The five motors provide impressive torque and a smooth cut, rivaling gas mowers in power. The 42-inch cutting deck is also a great size for most residential lawns, allowing you to finish quickly.

However, if you have a large property (over 2.5 acres) or need to mow in tight, wet conditions frequently, the battery limitations and higher price may be deal-breakers. User reviews are mixed: some praise the build quality and ease of use, while others report issues with battery longevity and the complexity of the five-motor system. For many, a gas mower remains more practical and cost-effective. Weigh the pros and cons carefully before making a decision.

What Is the Cutting Deck Size and Performance?

The MaximusZ features a 42-inch fabricated steel cutting deck, which is ideal for mid-sized lawns. It offers a cutting height range of 1.5 to 4.5 inches, giving you flexibility for different grass types and seasons. The deck is designed to provide a clean, even cut, and the five motors power each wheel independently, allowing for zero-turn maneuverability that's as good as any gas model.

In performance tests, the MaximusZ handles thick grass well, thanks to the high-torque motors. The variable speed drive lets you adjust ground speed from 0 to 7 mph, so you can slow down for tough spots or speed up on open stretches. The deck also features a washout port for easy cleaning, a nice touch for maintenance. Overall, the cutting performance is a strong point, but the deck size may be limiting for those with very large lawns.

Greenworks MaximusZ vs. Gas Mowers: Performance and Cost Over Time

When comparing the MaximusZ to a gas zero-turn mower, the electric mower shines in several areas. It's significantly quieter (around 70 dB vs. 90+ dB for gas), produces zero fumes, and requires less maintenance—no oil changes, spark plugs, or air filters. The instant torque from the electric motors also means quick acceleration and responsive control.

However, gas mowers still have advantages: they can run indefinitely with a fuel supply, are generally cheaper upfront, and have a longer track record for reliability. Over a 5-year period, the MaximusZ might save you $500-1,000 in fuel and maintenance, but the initial price difference is often $2,000-3,000 more than a comparable gas model. For most homeowners, the payback period is long, making the MaximusZ a premium choice for eco-conscious buyers who are willing to invest.

Warranty and Maintenance Considerations

Greenworks backs the MaximusZ with a 4-year limited warranty on the mower and a 2-year warranty on the battery. That's competitive with other electric mowers, but shorter than some gas mower warranties (which often offer 5 years on the deck and engine). The five-motor system is a unique design, and while it reduces mechanical complexity, it also means more components that could fail. Replacement motors and parts may be expensive, so check the warranty coverage carefully.

Maintenance is generally simpler: you'll need to keep the deck clean, sharpen blades regularly, and ensure the battery is stored properly during winter. The mower also has a built-in diagnostics system that alerts you to issues. However, finding a service center that can repair the five-motor system might be challenging in some areas. Consider these factors before purchasing.
