20" vs. 21" Self Propelled Head 2 Head!!!

I have completed about 5 cuts on the season with the 21" version. You may have read my impressions of it in another of my threads...I really like it.

Today, I opened up the garage to get a quick cut in and saw my 20" Ego mower just sitting there begging for attention . I just couldn't neglect it any longer. I took it for a spin today...it's first cut of the year. I must say it still does an excellent job even in the face of newer competition .

Guys, you may not like what I'm about to say but....I compared how my yard looked before this year after being cut with the 21" mower with how it looked today after a cut with the 20" mower..

I have to call it....I think the cut of the 20 inch may just be a hair better. I don't know, maybe my lawn looked better this time because it's starting to thicken up unlike past weeks this year.

The only possible explanation I can think of is that the stock blade on the 21" (like the 20" stock blade and all replacement blades I've gotten) comes relatively blunt.

Once it has been sharpened, I think it tends to perform better. So a used 20" blade might cut slightly cleaner than a brand new 21" blade. Otherwise the shape of the two is identical and should cut identically well.

Consumer Reports tested both of the 21" mowers and found them to perform exactly the same in mulching, bagging, and side-discharging—one rating higher than the 20" in all three categories.

Not arguing that a fresh mow with the 20" could subjectively look better to some in certain situations, but that is not because its performance is superior to that of either 21" model.

Point taken. What I am thinking though is that my grass is finally actively growing and this week it was at its longest this season. I also gave it a good, long watering yesterday.

Regardless, both do a good job. I did notice though that after pushing both mowers up a 30 degree incline that's about 25 feet up about 100 times, the weight differences in the mowers become apparent. The original mower can be slung around, the newer one not so much.

The weight difference is certainly noticeable, especially if you move them around at all when folded or have to lift over the lip of a shed.

The 20" was shockingly light—the 21" SP isn't overly heavy, probably still the lightest of its kind on the market. But the weight is probably the first difference that stands out when comparing the two.

Hmmm, looking at that pic, I do believe the 20 incher is the better looking mower of the two.

You're not seeing the 21s best side...a little lipstick... maybe?
