Who it fits
Good fit for
This mower suits homeowners with small to medium lawns who want a complete yard care kit. The 21-inch cutting width is efficient for average yards. If you already own DeWalt 20V tools, the battery compatibility saves you from buying new packs. The 45-minute runtime is enough for most residential jobs. The included trimmer handles edges and hard-to-reach grass. You get mulching, bagging, and side discharge flexibility for different yard conditions.
Who should skip it
Skip this if you need more than 45 minutes of continuous mowing time. The 21-inch deck may struggle with very large or overgrown properties. The 15.9-gallon bag requires frequent emptying on thick grass. If you prefer a single-unit system, the two-package delivery might be inconvenient. The trimmer is only 12 inches, which limits reach for tall weeds. You might need additional batteries for larger areas.
Verdict: This combo offers a practical, spec-driven solution for standard yard maintenance. The brushless motor and compatible batteries add value for existing tool users.
Key specs explained for this mower
Cutting Width: 21 in
The deck spans 21 inches across. This width covers more grass per pass than narrower 18-inch models. You will finish larger lawns faster. It fits standard garden paths without being too wide. Choose this size if you have open areas and want to reduce mowing time.
Battery Capacity: 2 x 8.0Ah
The mower uses two 8.0Ah batteries for power. Higher amp-hour ratings store more energy. This setup supports longer runtimes compared to single smaller packs. You can mow bigger yards before needing to recharge. Check if your existing tools use similar 20V batteries for shared charging convenience.
Runtime: 45 min
The batteries provide up to 45 minutes of operation. This duration suits medium-sized lawns. You can complete the task in one go if the area is not extensive. Larger yards may require swapping batteries or recharging. Compare this runtime with other models to ensure it meets your specific lawn size needs.
Motor Type: Brushless
The motor lacks carbon brushes, which reduces friction and wear. This design typically offers longer lifespan and better efficiency. You may experience quieter operation and less maintenance over time. Brushless motors often preserve battery life better than brushed alternatives. Look for this feature for durable, low-maintenance performance.
Design and Build Overview
The NBKXDEL 21-Inch Cordless Mower and Trimmer Combo arrives as two separate packages, so you should expect them to arrive at different times. The mower itself measures 35.6 inches in length, 16 inches in width, and 22.2 inches in height. These dimensions define the footprint you need for storage and transport. The unit is not a single solid block but a system of components. You will handle the 21-inch mower deck and the 12-inch string trimmer as distinct tools.
According to the listing, the mower features a single-lever height adjustment. This lever allows you to set the cutting height from 1.2 inches to 4 inches across eight distinct positions. You can change this setting quickly to match your lawn’s condition. The trimmer includes a dual-line auto-feed system. This layout lets you switch between trimming and edging without manual line advancement. The 15.9-gallon grass collection bag detaches easily for emptying.
Power comes from two 8.0Ah batteries for the mower and two 2.0Ah batteries for the trimmer. Both tools use brushless motors. This motor type reduces noise and extends operating time. The batteries are compatible with the DeWalt 20V series. This compatibility means you might already have power sources for this tool. The 3-in-1 function allows mulching, bagging, or side discharge. You choose the mode based on your yard maintenance needs.
Setup and daily operation guide
You receive two separate packages for this combo. Expect the mower and the 12-inch trimmer to arrive at different times. Assembly is straightforward. The mower features an 8-position single-lever height adjustment. You can quickly set the cutting height between 1.2 inches and 4 inches. This lever allows you to match your lawn’s needs without complicated steps. The trimmer includes a dual-line auto-feed system. This simplifies grass trimming and edging tasks in tight spaces.
Power comes from the included batteries. The mower uses two 8.0Ah packs, while the trimmer uses two 2.0Ah packs. Both units feature brushless motors. This design ensures durable performance, lower noise levels, and longer operating times. You can mow early in the morning without disturbing neighbors. The batteries are compatible with the Dewalt 20V series. This offers convenience if you already own tools from that brand. The included PD chargers support up to 45 minutes of runtime.
Daily mowing is flexible. The mower supports three working modes: mulching, bagging, and side discharge. You can choose the method that best suits your yard maintenance. The 15.9-gallon grass collection bag is large enough for most jobs. It is also effortless to detach and empty. This 3-in-1 functionality lets you adapt to different lawn conditions. The trimmer handles edge work and trimming with ease. Together, these specs provide a practical solution for common garden tasks.
Before You Buy This Combo
This listing bundles a 21-inch mower with a 12-inch trimmer. You receive two separate packages, so expect them to arrive at different times. The mower uses two 8.0Ah batteries, while the trimmer uses two 2.0Ah packs. The data notes battery compatibility with the DeWalt 20V series. You should verify your existing DeWalt chargers support the included 45W and 100W PD chargers. Runtime is listed at 45 minutes. This is sufficient for small to medium lawns. Larger yards may require spare batteries. The brushless motor reduces noise, making early morning mowing quieter. You will need to empty the 15.9-gallon bag regularly if using the bagging mode. Mulching requires a sharp blade. Keep spare trimmer line for the auto-feed system. This combo offers versatility but requires managing multiple battery types. Compare this against single-unit mowers if you do not need edging or trimming capabilities nearby. Check your storage space for the separate trimmer unit.
Check before you buy
- Verify DeWalt 20V charger compatibility for the included PD chargers
- Confirm your lawn size fits within the 45-minute runtime limit
- Plan storage for two separate packages arriving at different times
- Ensure you have spare trimmer line for the auto-feed system
