This HART 40 volt 20 inch self propelled mower stands out for its wide deck, decent runtime, and solid cutting performance on normal lawns. A 6.0 amp hour battery has covered about a quarter acre with charge left, and the mower has held up well over several years for some. The main drawbacks are weaker performance in thicker or taller grass and uncertainty around long term battery availability now that HART is no longer active. Warranty support has also been inconsistent, though replacement batteries have been sent in some cases, making it a practical choice if the size and battery situation work for you.
The mower can deliver real runtime, mowing about 0.25 acres with a 6.0Ah battery and leaving juice remaining.
The mower can keep running for years, with reports of roughly four years of use and good performance.
HART warranty support reportedly includes sending replacement batteries after mower battery failures.
The system reportedly supports an adapter that can let you use Ryobi batteries with this mower setup.
The battery availability risk can increase because Hart is no longer active, which may affect aftermarket battery access.
The mower can struggle in thicker or higher-density grass, slowing the motor and potentially getting stuck if mowing continues.
Warranty handling can be unreliable, since one battery failure was approved but no replacement was sent despite repeated contact attempts.
Warranty shipping can stall after approval, leaving the mower without a replacement until a spare battery is used.

20, 21 inches is what you want, you don't need self propelled for an electric lawn mower.
You get something like a 14, 16 inch lawnmower you will be walking yourself to death, it adds up, the missing width.
Interestingly with Kobalt, Lowe's never has a replacement blade and they give you no help, it took me a year and a half of searching to find out that Greenworks makes it.
They have two 20-in blades one is non-painted it won't work, it's the painted green one in their brand.
With electric lawn mowers you just can't go buy a generic blade they're typically shape-coded.
Example our blade has two reversed hearts left and right of the mounting point. Not only do you have to match the length you got to match these lineup points shapes, they help the blade to lock in on the hub.
