Greenworks 40V 21" Brushless Cordless (S vs Litheli 18-inch 40V Self-Propelled Brush
Quick Verdict
The Greenworks 40V 21" Brushless Cordless Self-Propelled Lawn Mower is the clear winner for most homeowners with medium to large yards. It offers a wider cutting deck, stronger consumer ratings, and a proven track record. The Litheli 18-inch 40V Self-Propelled Brushless Lawn Mower is a budget-friendly option that works for smaller, simpler lawns but falls short on power, cut width, and reliability based on user feedback.

Where Greenworks Wins
Wider cutting deck – The 21-inch deck covers more grass per pass, reducing mowing time by roughly 15% compared to the 18-inch Litheli. This matters for yards over 1/4 acre.
Higher reliability – With over 1,500 reviews and a 4.1-star average, Greenworks has a strong track record. The Litheli’s 3.7-star rating and lower review count suggest more variability in quality and customer satisfaction.
Better brand support – Greenworks has an established parts network, customer service, and accessory ecosystem. Litheli is a newer, smaller brand with less aftermarket support.
More powerful cutting – The 21-inch deck typically houses a larger motor and blade system, handling thicker grass and uneven terrain better than the 18-inch model.
Higher resale value – Greenworks holds value better due to brand recognition and battery compatibility across a wide range of tools.
Where Litheli Wins
Lower upfront cost – At $239.99, the Litheli is $160 cheaper than the Greenworks. If you’re on a tight budget and have a small, flat yard, this may be attractive.
Slightly lighter – The 18-inch deck and likely smaller battery mean less weight to push, though both are self-propelled. This can help on steep slopes or when maneuvering in tight spaces.
Adequate for small yards – For lawns under 1/4 acre, the 18-inch cut width is sufficient, and the lower price makes sense if you don’t need extra capacity.
Simpler controls – Fewer features can mean fewer things to break, which some users prefer for a no-frills mower.
Which Should You Buy
Choose the Greenworks 40V 21" if: You have a lawn between 1/4 and 1/3 acre, want a mower that will last several seasons, and value a wider cut, stronger brand reputation, and higher user satisfaction. The extra $160 buys proven performance and better support.
Choose the Litheli 18-inch 40V if: Your yard is under 1/4 acre, you need to minimize spending, and you’re comfortable with a less established brand and lower average ratings. It’s a functional entry-level option but not a long-term investment.
For most buyers, the Greenworks delivers better value over time. The Litheli is only recommended for strict budget scenarios or very small, simple lawns.
