EGO LM2156SP Select Cut: the best cordless self-propelled mower
The Select Cut multi-blade system is a genuine improvement in mulch quality: three smaller blades with independent action re-cut clippings to a finer size than a single blade, producing a mulch that disappears into the lawn immediately rather than sitting on top. SmartPace drive automation senses when the operator speeds up or slows down and adjusts drive speed automatically -- this feels natural from the first use, unlike fixed-speed drives that require deliberate speed selection. Slope performance on our 15-degree test was flawless at all three mow passes. At 70 minutes runtime, one charge covers a 1/2-acre lot.

DeWalt DCMWSP244U2 FlexVolt: best for DeWalt/20V platform users
The DeWalt FlexVolt self-propelled mower at 60 minutes runtime and 15-degree slope performance covers the vast majority of residential applications. For homeowners on the DeWalt 20V MAX or FLEXVOLT platform who want their mower batteries to share with other tools, the DeWalt provides competitive performance at less than the EGO without platform fragmentation.
How to choose
Drive speed range
0.9-3.1 MPH covers the full range from careful trimming pace to fast mowing. Variable speed is preferred over single-speed drive.
Rear-wheel drive for slopes
Rear-wheel drive provides better traction on inclines by putting drive force on the heavier rear wheels. Front-wheel drive loses traction on inclines when weight shifts rearward.
Automatic pace-matching
SmartPace or equivalent automatic speed adjustment makes self-propelled mowing feel natural. Fixed-speed drives require deliberate adjustment and feel mechanical.
Runtime for your lawn size
Verify runtime specification with your specific battery size on lawns comparable to yours. Thick grass and slopes reduce runtime by 20-30% vs. flat, light-growth conditions.
Deck height single-point adjustment
A single lever that adjusts all four wheel heights simultaneously saves time and avoids the common problem of setting different heights at different wheels.
Common questions
On any incline over 5 degrees and on lawns over 6,000 sq ft, self-propelled reduces operator fatigue significantly. The drive eliminates the need to push the mower uphill, which is the primary fatigue factor in manual lawn mowing.
Most residential self-propelled mowers handle 10-15 degree slopes reliably. Premium models like the EGO LM2156SP are rated to 20 degrees. Beyond 20 degrees, wheeled mowers of any type become unsafe.
Variable speed allows the operator to choose the drive speed from 0.9 to 3.1 MPH (or in the case of EGO's SmartPace, the drive automatically adjusts to the operator's walking speed). This prevents the mower from dragging or lagging, making mowing more natural.
Not necessarily. Better slope performance comes from rear-wheel drive configuration and the drive wheel's grip pattern. Front-wheel drive mowers can lose traction on inclines when the weight shifts to the rear.
