Who it fits

Key specs explained

Motor Type: Brushless

This mower uses a 670-watt brushless motor instead of a traditional brushed design. Brushless motors generate less heat and friction, which helps them last longer and run more efficiently. You get consistent power without the wear and tear of carbon brushes. This means less maintenance for you and a tool that holds up better over time compared to older brushed models.

Runtime: Up to 25 min

The dual battery system provides up to 25 minutes of continuous runtime. This duration is suitable for small to medium lawns where you can finish the job in one go. If your yard is larger, you may need to recharge or manage sections carefully. Always compare this figure with other cordless mowers, as runtime varies significantly based on grass thickness and cutting height settings.

Cutting Width: 17 in

The 17-inch cutting deck determines how much grass the mower cuts in a single pass. This width is standard for push mowers, offering a balance between maneuverability and coverage speed. It is wide enough to handle average residential yards efficiently but narrow enough to navigate around garden beds and obstacles. Compare this with wider models if you have large, open spaces.

Cutting Height: 1-3 in, 6 positions

You can adjust the cutting height from 1 inch to 3 inches across six distinct positions. This range allows you to tailor the cut to your grass type and seasonal needs. Lower settings give a manicured look, while higher settings protect grass during hot or dry periods. Having multiple positions gives you control over lawn health, unlike mowers with fixed or limited height options.

Design and build details

The deck is made from steel, which the listing notes as durable. This material choice supports the 17-inch cutting width. You get a clean cut in one pass. The steel construction helps maintain the blade's alignment over time. The mower is a push model, meaning you provide the forward motion. There is no self-propulsion system. This layout keeps the design simple. You control the speed by walking. The unit weighs 33.8 pounds. This weight is manageable for most users. It is light enough to move around the yard but heavy enough to stay stable during operation.

The overall dimensions are 48.4 inches long, 17.7 inches wide, and 42.9 inches high. These measurements affect storage and maneuverability. The width fits through standard gates. The height allows for easy storage in most sheds or garages. The 11-gallon grass catcher is included. It features a built-in indicator window. You can see when the bag is full without opening it. This reduces thatch and keeps your lawn tidy. The height adjustment has six positions. You can set it from 1 inch to 3 inches. This allows you to tailor the cut to your lawn's needs. The finish is standard for this class of tool. It is designed for outdoor use. According to the listing, the materials are chosen for longevity. You do not need to worry about rust or cracking under normal conditions. The build supports consistent performance.

Setup and everyday use guide

Setting up this mower involves assembling the handle and attaching the two 24V 4.0 Ah lithium-ion batteries. The listing notes that the unit comes with a dual-port charger, allowing you to power both batteries simultaneously. This setup process is straightforward, requiring no external power cords. Once assembled, the mower stands 42.9 inches tall and weighs 33.8 pounds. Its 17.7-inch width and 48.4-inch length provide a manageable footprint for storage and maneuvering. You do not need to worry about tangled cords during operation. The push drive type means you guide the mower manually. There is no self-propelled mechanism, so you control the pace. Daily use begins with selecting your preferred cut height. The six-position adjustment allows settings from 1 inch to 3 inches. This range lets you tailor the cut to your lawn’s needs. The 17-inch steel blade ensures a clean path in one pass. As you mow, the 11-gallon grass catcher collects clippings. An indicator window on the bag shows when it is full. This feature helps you manage thatch and maintain a tidy lawn. The brushless motor delivers consistent power for up to 25 minutes of runtime. You can monitor battery life via the charger or the mower’s system. After use, empty the bag and store the unit. The steel deck resists wear, and the cordless design keeps your yard free of tripping hazards. This model suits small to medium lawns where manual pushing is acceptable.

Before You Buy This Mower

This Sun Joe model is a push mower, so you must walk behind it to operate. It lacks self-propulsion, which means you provide all the forward motion. The 17-inch cutting width is narrow compared to larger options in this guide. You will need more passes to cover the same area as wider decks. The 11-gallon bag is large, but you must empty it frequently to maintain optimal airflow and cutting performance. Check that your existing 24V batteries are compatible if you plan to swap them, though the listing includes two 4.0 Ah units. The brushless motor requires no carbon brush replacements, reducing long-term maintenance. However, you still need to keep the steel deck clean and the blade sharp for a clean cut. This unit fits best for small, flat lawns where maneuverability matters more than speed. It is a simpler choice than self-propelled models but requires more physical effort from you.

Check before you buy

• Confirm your lawn size fits a 17-inch cutting width.
• Check if you are comfortable with a push-only design.
• Verify battery compatibility if using existing 24V units.
• Ensure you have space for the 11-gallon bag.
