In the crowded cordless mower market, Ryobi’s 40V HP Brushless 21-inch self-propelled mower has quietly turned into a workhorse flagship for Techtronic Industries, thanks to a full-size 21-inch steel deck, dual active battery ports and a brushless motor tuned to mimic the torque of a small gas engine while cutting maintenance to a minimum. The mower sits in Ryobi’s 40V platform and is sold at Home Depot in the US, typically bundled with a pair of 40V batteries and a rapid charger for around $699 depending on the specific configuration and retailer promotions. Ryobi’s official product page for its 40V HP Brushless 21-inch self-propelled mower lists the unit as compatible with the broader 40V ecosystem, highlighting its role as an anchor product in the outdoor range.

How the Ryobi 40V HP mower is built for platform buyers

The Ryobi 40V HP Brushless 21-inch self-propelled mower is positioned as a flagship within the 40V outdoor lineup, pairing a high-efficiency brushless motor with a 21-inch cutting deck, variable-speed self-propelled drive, and three-in-one bagging, mulching and side-discharge options that cover typical suburban lawn sizes up to about half an acre on two 6.0 Ah packs in normal conditions. Ryobi specifies up to 70 minutes of runtime on a pair of 6.0 Ah 40V batteries under ideal test conditions, and the design uses load-sensing electronics to step up power in thicker grass and throttle back in lighter passes to stretch runtime without user input.

One of the key platform hooks is the dual active battery ports: both 40V packs sit on board at once, allowing the mower to draw down one and then the other automatically rather than requiring users to stop and swap packs mid-cut. Ryobi’s 40V HP designation indicates that the mower is designed around high-performance 40V packs and brushless electronics, and the same batteries can be moved into more than 75 compatible tools including trimmers, blowers and chain saws across the 40V lineup, turning the mower into a gateway product for homeowners building out a cordless yard-care kit. The cutting height is centrally adjustable across seven positions, usually covering roughly 1.5 to 4 inches, so users can shift from a low, manicured look to a taller, heat-resistant summer cut without walking around the deck to change each wheel independently.

Ryobi has also leaned into storage and maneuverability, equipping the 40V HP Brushless 21-inch self-propelled mower with a fold-over handle system and a vertical-storage-compatible design so the unit can stand on its rear end in a garage, occupying a footprint similar to a push broom instead of a full horizontal space. The self-propelled drive offers variable speed via a thumb or handle control (depending on the exact sub-model), which allows users to match walking pace and manage slopes more comfortably than with a fixed-speed transmission. For noise-sensitive neighborhoods, Ryobi notes that the 40V HP mower runs dramatically quieter than a typical gas push mower and produces zero tailpipe emissions during use, a point that has helped cordless systems win favor in markets where local ordinances are tightening on gas equipment.

In independent testing, reviewers have generally pointed to the Ryobi 40V HP Brushless 21-inch self-propelled mower as one of the more balanced options in its price bracket, with strong cutting performance in normal-length grass and useful convenience features like on-board LED headlights for low-light mowing and a simple single-lever deck-height adjustment, while also noting that wet, overgrown lawns can still challenge battery runtime and require slower passes. A recent long-term review from consumer-tech site The Verge’s sister outlet highlighting cordless lawn tools described Ryobi’s 40V HP mower as a “solid all-rounder” for medium yards, particularly for users already invested in Ryobi’s battery ecosystem, while flagging that buyers with very large properties may still prefer a riding mower or a higher-voltage system.

Because the Ryobi 40V HP mower is sold primarily at Home Depot in North America, pricing and configurations can vary, with some kits including a single high-capacity battery and others shipping with two or more packs along with a rapid charger; discounts often appear around spring promotional events tied to lawn and garden resets, and secondary retailers in Canada and selected online marketplaces carry similar or slightly modified versions for regional markets. An updated Home Depot product listing for the Ryobi 40V HP Brushless 21-inch self-propelled mower kit recently advertised a bundle with two 6.0 Ah batteries and rapid charger at a mid-$600s price point before local taxes, underscoring that the mower targets serious DIY users rather than entry-level buyers looking for the cheapest possible push mower.

Strategically, Techtronic Industries uses Ryobi’s high-volume 40V mowers as a way to deepen relationships with big-box retailers like Home Depot, while its Milwaukee brand concentrates on professional power tools and jobsite equipment sold through trade channels. The company has highlighted outdoor power equipment as a growth engine in recent annual reports, with platform ecosystems such as Ryobi 18V ONE+ and 40V lines designed to lock in repeat battery and tool purchases across seasons. According to Techtronic’s latest investor materials, outdoor products and floorcare together form a substantial share of group revenue, and the company continues to invest in cordless innovation and capacity expansion in North America and Europe. Techtronic’s 2024 annual report points to continued demand for cordless outdoor products and emphasizes Ryobi’s position in big-box retail channels.

Techtronic Industries’ shares (HK0669013440) closed on the Hong Kong Stock Exchange at HKD 103.50 on 06/13/2026, reflecting investor expectations around the company’s ability to sustain cordless growth in both power tools and outdoor power equipment segments.
