Hi. Does the 20 and 21 inch mower contain the the same technology other than the span of the blade? Are there features in the 21 inch mower not present in the 20 inch mower?

The 21" is more powerful (700W push, 1000W SP, vs 600W for the 20"), has a wider range of cutting heights, has three height positions for the handle instead of two, offers a SP version, and has a variable speed blade motor to adjust the blade speed to cutting conditions.

I have the 20" and I'm happy with it. Some people with extremely thick grass and/or grass that is cut at a very low height have commented that the 20" can lack power, requiring a slower walking pace to keep from overloading the mower, but I don't find I have this problem. However, I generally cut my grass at the highest setting.

One advantage the 20"'has over the 21" is weight; the 21" weighs more, but even the SP version weighs considerably less than a gas mower.
