Detailed Description
Remember when mowing didn’t require gas, oil, or a pull cord? The WEN 20V cordless lawn mower brings that convenience back. The brushless motor fires up quickly and runs at up to 3,100 RPM on the 17-inch blade. Because it’s brushless, you get reduced maintenance and a longer life span — ideal if you’re searching for a durable, low-maintenance mower.
The mower is lightweight and portable, with a collapsible handle for upright storage and easy transport. Switching between mulching and bagging is simple: the included mulching plug makes mulching effortless, and the 13-gallon bag catches clippings when you prefer a tidy finish. With two 5Ah batteries and a dual-port charger, it’s also a strong pick if you want a dual battery mower that’s ready out of the box.
This model is particularly well suited as a quiet brushless 19-inch battery mower for small yards or as a best battery mower for medium lawns with 5Ah batteries, offering long runtime and enough cutting width to reduce passes.

Comparison with Similar Products
Compared to other brushless 20V mowers and cordless mulcher models, the WEN 20839 stands out for including two 5Ah batteries and a dual-port charger in the box (many competitors sell batteries separately). Its 19-inch deck places it in the sweet spot between compact 16–18 inch mowers and larger 21-inch models — offering a balance of maneuverability and cutting coverage.
For those prioritizing runtime, the dual 5Ah configuration can often outperform single-battery competitors. If you need the absolute largest deck or worksites beyond 1/4-acre, consider a 40V or 60V platform; but for most suburban yards, this WEN 20V Max 19-inch cordless brushless mower is a compelling, budget-friendly choice.

- Sharpen the 17-inch blade at the start of the season and check balance regularly.
- Store batteries in a cool, dry place and recharge before long storage.
