Who it fits
Good fit for
You should choose this mower if you have a medium yard up to 600 m². The dual-battery system provides enough energy for larger areas without frequent recharging. The 17.5-inch deck balances coverage and maneuverability. If you prefer bagging or mulching, the 2-in-1 function offers flexibility. The 50L box reduces how often you stop to empty clippings. The six height settings let you adapt to seasonal grass growth. This setup is practical for owners who want consistent power without cords.
Who should skip it
Skip this model if you need to mow large properties over 600 m². The battery capacity may limit runtime for extensive lawns. If you require a wider cutting path, this 17.5-inch deck is narrow compared to commercial options. You might also look elsewhere if you need a 3-in-1 system with side discharge. The 26.4-pound weight is manageable but heavier than some ultralight models. Users seeking a single-battery tool may find the dual-system requirement cumbersome. Check your yard size against the 600 m² limit before buying.
Verdict: This mower offers solid specs for medium yards under 600 m². The dual-battery system and brushless motor provide reliable performance.
Key specs for this mower
Voltage: 40V
This mower uses a dual-battery system that combines two 20V sources to create 40V of system power. You get stronger cutting performance than standard 20V models. The higher voltage helps maintain consistent speed as grass conditions change. This is useful if you have dense or tall grass. It ensures the motor does not slow down under load. You should compare this to single-battery 20V units for power differences.
Motor Type: Brushless
The brushless motor reaches 3,600 RPM for efficient cutting. This design reduces internal friction and heat. You benefit from longer motor life and less maintenance over time. There are no carbon brushes to wear out or replace. This leads to higher efficiency and consistent power delivery. When shopping, look for this feature to ensure durability. It is a standard upgrade for modern cordless mowers.
Cutting Width: 17.5 in
The deck width is 17.5 inches. This size balances coverage area with maneuverability. You can mow medium-sized lawns efficiently without the bulk of wider decks. It fits through standard garden gates and around obstacles. Smaller decks require more passes. Wider decks cover more ground but are harder to handle in tight spaces. This width is a practical choice for average residential yards.
Battery Capacity: 2x20V Max 8.0Ah
The system uses two 8.0Ah batteries for a total of 296Wh of energy. This provides 48% more capacity than a 200Wh setup. You get up to 600 square meters of coverage per charge. The larger reserve supports efficient mowing across larger areas. You do not need to stop and recharge mid-job. Compare this to smaller 4.0Ah or 2.0Ah batteries for runtime differences.
Cutting Height: 25-75 mm, 6 levels
You can adjust the cutting height in six steps from 25 to 75 millimeters. This range adapts to different grass types and seasons. You can set a higher cut for dry weather to protect roots. A lower cut keeps the lawn neat in spring. This flexibility helps maintain grass health. When shopping, check if the adjustment is single-lever or individual. This model offers simple height control for various lawn needs.
Design and build overview
The KraftSense Aurora-X20 features an Aurora Green finish according to the listing. The unit measures 18.4 inches in width, 43.8 inches in height, and 45.5 inches in length. It weighs 26.4 pounds. These dimensions place it in the compact category for walk-behind mowers. The 17.5-inch cutting deck balances area coverage with maneuverability in medium gardens. The relatively low weight aids in pushing the mower across uneven terrain and reduces fatigue during longer mowing sessions.
The design supports a 2-in-1 mulching and bagging configuration. A 50L grass box is included for clippings, which reduces the need for frequent emptying. You can adjust the cutting height across six levels, ranging from 25 to 75 mm. This adjustment range allows you to adapt to different grass conditions and seasonal changes. The brushless motor is housed within the deck assembly, contributing to reduced friction and longer motor life. The layout prioritizes practical maintenance, as the listing notes the inclusion of three durable blades. This setup ensures you have spares for convenient replacement without needing to purchase additional parts separately.
Setup and everyday use guide
The KraftSense Aurora-X20 requires two 20V Max 8.0Ah batteries to operate. The listing specifies a dual-battery system that combines these sources to deliver 40V of system power. You must insert both batteries into the mower to activate the brushless motor. This configuration provides 296Wh of total energy, which the manufacturer states supports mowing areas up to 600 square meters per charge.
Daily operation begins with adjusting the cutting height. The mower offers six distinct levels ranging from 25 to 75 millimeters. You select the desired height based on your grass conditions and seasonal needs. The 17.5-inch cutting deck allows for efficient coverage of medium-sized yards while maintaining manageable maneuverability.
For grass management, you can choose between mulching or bagging modes. The 50-liter grass box holds a significant volume of clippings, which reduces the frequency of emptying during longer mowing sessions. The brushless motor runs at 3,600 RPM, delivering consistent cutting performance. This speed helps maintain efficiency as you encounter varying grass thicknesses.
The unit includes three durable blades: one pre-installed and two spares. This provision allows for convenient replacement without immediate additional purchases. The 3-year warranty covers the mower, while the batteries carry a 1-year warranty. You can rely on these specifications for straightforward maintenance and reliable performance throughout the mowing season.
What You Need Before Buying
You need two 20V Max 8.0Ah batteries to power this unit. The listing states these are sold separately. Ensure your existing batteries are compatible with the dual-battery slot. The 296Wh energy reserve supports lawns up to 600 m². If your yard is larger, you may need spare batteries to finish the job without interruption. Keep the three spare blades ready for replacement. The brushless motor reduces friction, but you should still clean the 50L grass box after each use to prevent clogs. Adjust the six height settings based on grass length. This mower sits in the medium-yard category. Compare its 17.5-inch deck against wider options if you have large open spaces. Choose this if you prefer a compact footprint and already own compatible 20V batteries. Check your storage space for the 45.5-inch length.
Check before you buy
- Confirm you own two compatible 20V Max 8.0Ah batteries.
- Verify your lawn size is under 600 m².
- Check storage space for the 45.5-inch length.
- Ensure you have room for the 50L grass box.

Frequently asked questions
Is the KraftSense 17.5 mower suitable for slopes?
The 26.4-pound weight helps stabilize the unit on gentle inclines. However, the 17.5-inch cutting width and push-only design require you to manage the momentum yourself. You should test the slope in your yard first, as steeper grades may make it difficult to maintain a steady pace without the assistance of a self-propelled system.
How does the brushless motor affect maintenance?
Brushless motors eliminate carbon brushes, which reduces friction and wear over time. This design typically extends the motor's lifespan compared to brushed alternatives. You will likely spend less time on internal motor maintenance, though you must still care for the blades and deck to ensure optimal cutting performance and safety during use.
What is the maximum cutting height for this model?
Specific height settings are not listed in the provided specifications. You should check the product manual or the manufacturer's website for the exact range. Typically, these mowers offer multiple positions to adjust the deck height, allowing you to accommodate different grass types and seasonal growth patterns effectively.
Does the Aurora-X20 include a bag for clippings?
The provided data does not mention a grass collection bag. You may need to purchase one separately if your lawn care routine requires bagging clippings. Check the product listing or contact the seller to confirm if a bag is included or available as an accessory for this specific model.
Can I use third-party batteries with this mower?
The listing specifies the use of two 20V Max 8.0Ah batteries. You should verify if these slots accept other brands or only KraftSense branded units. Using non-compatible batteries could void warranties or damage the dual-battery system. Stick to the recommended specifications to ensure safe operation and consistent power delivery.
Is this mower quiet enough for early morning use?
Brushless motors generally operate more quietly than brushed ones due to reduced mechanical friction. The 40V system provides efficient power without excessive noise. However, specific decibel levels are not provided. You can expect a moderate sound level, but consider checking local noise ordinances if you plan to mow early in the morning.
How do I store the mower when not in use?
The unit measures 45.5 inches in length and 43.8 inches in height. You should store it in a dry, covered area to protect the electronic components and metal deck from moisture. Remove the batteries before storage to preserve their charge and lifespan. Ensure the mower is stable and cannot tip over.
