Home Depot currently has a 1 day sale on the 20" walk behind with a 5ah battery for $359. Their 21" is $400 with the same battery. Should I go with the 20" for the sale? Not really sure what the difference is between the two mowers besides the 1" difference and variable cutting heights.

21” has a bit more power in case you have really thick grass, and cuts 1/2” higher if you like cutting your grass tall. Three handle height settings instead of two.

20” is a little lighter, a little smaller, a little easier to maneuver. Some say it mulches better, but this is likely based more on grass type.
