KraftSense 18-Inch 40V Max Brushless Cordless Self-Propelled Mower — 40V 4.0Ah, 18" Deck

The KraftSense 18-inch 40V Max brushless cordless self-propelled lawn mower is a battery-powered mower with an 18" deck, a brushless 3,600 RPM motor, and a 40V 4.0Ah (148Wh) battery for quiet, maintenance-light yard work.

This mower combines a high-efficiency brushless cutting system and a self-propelled drive to make residential lawn care faster and easier without gasoline or oil. It ships with a 40V Max 4.0Ah battery and charger, offers up to roughly 30 minutes of runtime per charge depending on conditions, and provides 6 height settings with both mulching and rear-bag collection options. Backed by a 3-year tool warranty and a 1-year battery warranty, it’s built for homeowners who want a low-maintenance electric alternative to small gas mowers.

How does the battery power performance compare to small gas mowers?

The 40V Max 4.0Ah battery delivers 148Wh of energy, which is designed for typical residential mowing sessions up to about 30 minutes per charge. Brushless motor efficiency helps translate battery energy into steady cutting speed and torque, minimizing stalls in normal lawn conditions.

• 40V Max 4.0Ah (148Wh) included battery and charger for plug-and-play use
• Brushless motor up to 3,600 RPM for consistent blade speed
• Estimated runtime of up to 30 minutes per charge under moderate load
• Cleaner startup and no fuel storage or engine tune-ups

What makes the self-propelled drive useful for yard work?

The mower’s variable self-propelled system reduces the physical effort of mowing by adjusting drive speed from 1.3 to 2.9 mph. This is helpful on flat lawns and gentle slopes, so you spend less time pushing and more time guiding the mower for even results.

• Adjustable drive speed between 1.3 and 2.9 mph for personalized control
• Designed to ease pushing on up to 1/8-acre lawns
• Compact 18-inch cutting width hits a balance of coverage and maneuverability

Can it handle different grass heights and disposal preferences?

The mower offers six cutting positions that adjust blade height from 1.0 to 3.0 inches, making it adaptable for seasonal needs and grass variety. You can switch between mulching to return fine clippings to the lawn or rear-bag collection using the included 50L grass bag for a cleaner finish.

• 6-position height adjustment from 1.0 to 3.0 inches for versatile mowing
• 2-in-1 operation: mulching or rear bagging with the 50L collection bag
• 50L bag capacity reduces stops for emptying on average-sized yards

What about maintenance, durability, and warranty?

Electric tools typically need less routine care than gas equipment, and this mower follows that trend: no gasoline, no oil changes, and fewer seasonal tune-ups. The brushless motor requires less service than brushed designs, and KraftSense supports the tool with a 3-year warranty, plus a 1-year warranty for the battery for added peace of mind.

• Brushless motor for longer life and lower maintenance
• No fuel, oil changes, or spark plugs to replace
• 3-year tool warranty and 1-year battery warranty for reliability

Who is this mower best for? Homeowners with small to medium yards—roughly up to an eighth of an acre—who want a quieter, low-maintenance alternative to a gas push mower will find this model attractive. It suits users who value easy storage, straightforward operation, and the convenience of battery power with the option to mulch or collect clippings. If you need a compact, efficient mower for routine lawn care without dealing with fuel, this KraftSense model is designed to deliver consistent, user-friendly performance.
