I'm wondering whether I can get a blade for my 21 inch mower that simply cuts the grass without mulching it. I have used the mower four times with varying success on tall wet grass and medium dry grass on setting 3 for height. I mowed the entire yard without recharging when the grass was dry and medium height. I tried this again today but with the height setting at 2 because we will be gone for 10 days on vacation. This caused the mower to work much harder and I needed to recharge the battery twice. I'm wondering if having a conventional, non-mulching blade and using a side discharge chute would be a better option for me. At this point, I believe it will be necessary to purchase an extra battery or else get rid of the mower. The reality of the situation is that if we have regular rainfall, then mowing can't occur until the grass becomes too tall to be practical for this mower.

No.  The blade doesn't really mulch.  If you were to carefully inspect blades of grass you just cut, you would find that they are cut ONCE.  A true mulching mower will repeatedly cut each blade until they are finely cut up into small pieces.   Your Ego mower is not mulching, despite advertising to the contrary.

And you are correct, that if you have to wait for the grass to dry from rains, it may be so tall that this mower can't handle the load.   I had a Honda Harmony, which was a fantastic mower (it mulched superbly), vacuumed up debris like a Hoover, and was very reliable.  the ONLY reason I switched to the Ego was to get away from the exhaust of a gas mower.  Having electric means making a lot of sacrifices in mulching performance, durability (don't hit an immovable object with the Ego), and raw power.   But I love it's quietness and lack of exhaust.

Thanks for responding. I agree that having a quieter experience mowing is a huge benefit and I'm willing to make some sacrifices to have that. Having to wait for the battery to charge twice is too much for me though. I took a break and had a beer while the battery charged the first time, but that's enough. This mower really does seem to mulch to me. Much of the grass looks like it came out of a blender and I have to clean the wet mess that has collected on the inside of the deck every time I empty the bag, which is often. I just mowed this afternoon and the grass was completely dry and still this wet goo of grass just complicated the whole process. Maybe the grass here in southwest VA is just too lush for this type of mower.

I had a Honda Masters and Harmony prior to my Ego mowers as well. One came with dual-blade mulching setup, the other had a dual blade mulching retrofit kit. I get just as good a cut with my Ego mower:







I'm not discounting the issues others are experiencing, just pointing out that these aren't universal problems that affect everyone. Certainly no reason to doubt the hundreds of positive reviews, top rating from Consumer Reports, or to pass on the mower without giving it a try for yourself.

The mower blade isn't perfect, and hopefully will be improved by Ego or someone else in the near future, but it isn't the epic disaster that some want you to think it is.

I have never seen any grass come out of my 21-inch self-propelled ego mower that looks like it has been mulched when the mulching plug is installed. so I gave up and went back to bagging. I looked at your pictures and that is not what I get when I use the mulching plug I usually cut about 2 inches of grass leaving two and a half inches

Those photos are not mine, they are from a responder. The grass I have has grown from plenty of recent rains and after the mower has chewed it, some of it looks a bit like canned spinach-- as if you put grass in a blender. It cakes all around the inside of the deck up to about a half inch thick. Maybe I'll take a few photos tomorrow and post them.

Try coating the deck with something like a graphite mower deck spray after cleaning all of the grass buildup off. Others here have had luck with some kind of all-surface motorcycle protectant spray. Either will protect the surface and reduce grass buildup much longer than a general WD-40 or silicone-type of lubricant spray. And of course ensuring the blade is razor sharp will help too.

I know what you mean about grass buildup when mowing within a few days after a heavy rain or while the grass is wet. I hadn't treated my mower deck in a while and it was a real pain. The 7.5Ah battery would keep the blade spinning, but the cut wasn't as good and the run time was maybe half. The 2.5Ah battery just laughed and shut off.

Once again, I do believe that a lot of people are getting "good" to "great" cutting results.  As for me, I was super excited to try my new 21" SP, but was left disappointed with its "mulch" cutting capability.  I even tried it for 45 days before returning it to HD and went back to gas and bought a "dual cutting blade" from Honda.

As previously stated, I have nothing against EGO and their products - as I own their 15" trimmer and their 530 CFM leaf blowers.  I love these two power tools and have no issues with them.  As with their lawn mower, it did not perform well on my yard.  Even when I go over each pass twice, it would leave behind a trail of clippings on the left side of the mower.

I can not speak for everyone else as every yard is different in the grass type, texture, soil composition, watering & fertilization patterns, and weather condition.  Therefore, I do agree with David Cline that everyone should try out the EGO lawn mower for themselves and determine if this machine is what you are looking for.  I would recommend that you open up a HD credit card, as you will get $25 Off of your first purchase.  In addition, you have up to 365 days to return your product for a FULL REFUND - so what do you have to lose.

365 days, seriously?  I thought it was 90

90 days if you pay with cash or your own credit card. But with HD credit card, you'll get the 365 day benefits. That's why I buy all my EGO products on the HD card.

I've tried 3 methods of preventing buildup.  Graphite spray didn't work well for me.  A dry lube didn't help.  Someone suggested car wax.   For me, that works the best.

Car wax worked for me. Even if dried on the grass peels off like a decal if you can catch the edge with a plastic scrapper.

I actually used WD40 when I first brought my 21SP home, and that worked well for me.

It works great, but isn't really a permanent coating. I used a silicone WD-40 spray a few times cutting wet grass and it made a big difference at first but was useless by the time I finished. That was probably on my old Honda with a metal deck though, so it might work longer on a plastic surface.

I have to respray it every 3rd or 4th cut, depending on whether I have to cut my grass once or twice a week, and that seems to work well.
