I recently purchased my mower and am pretty happy with it. However, the blade isn't built with high quality metal. It's already nicked up and doesn't feel like it's very durable. Does EGO offer an alternative blade? Can I buy a different blade from another manufacturer?

I just bought mine a mo ago and have used it a few times already.....I know the blade seems a little flimsy but not sure about after market blades.

On another note, have you noticed, if yours is the 2100sp, does it leave uneven lines? Mine does and there's a lot of talk about this on the Ego community. Have you got this issue? If so, did you fix yours and how?

Ideally, EGO mowers would be compatible with universal 21 inch blades, but I think that might cause warranty complications were EGO to actually support something like that, otherwise, I would have been on the lookout for an Oregon blade to put on it, or a Toro blade if they have any universal ones.

I haven't experienced the uneven lawn issue, but I mow on setting 4. Not sure if your issue might be caused due to a shorter cutting height. I do experience the issue where a few strands of grass are not cut down properly and stick out. I think that's an issue with the blade though which is why I'm looking for a replacement.

I had the same issue with my 21" self propelled.  I discovered that if you put any downward pressure on the handle, the mower deck flexes causing uneven cutting.  If you put the mower on concrete, and start to apply downward pressure on the handle, you can see that the left front wheel lifts up first due to frame flex.  I have changed the way I hold the handle, including raising the handle and have virtually eliminated the striping like you are seeing.

Marco, right now the only blade options for the 21" mower are the stock blade and the High Lift blade. Both are made by Ego.

I have the uneven cutting problem. The right side of the mower will not pull up the prior pass wheel rut. I put on another blade that I had lying around. It was heavier and did a wonderfull job of cutting However the mower was louder and the battery didn't last as long. Considerably less. Conclusion the motor was working harder to spin the heavier blade. Got the high lift blade but it did not cut any better, motor was louder and the battery life less. Only solution I have found is to mow clock wise so left side is raising the wheel rut

I ordered my High Lift blade through Amazon about a month ago and it just arrived today. I mowed my front and backyard and the difference between the two blades is amazing! The new high lift blade picked everything up and left the lawn much neater looking!!

Since I have new sod (4 months old and thick and healthy, cut to 4" height (position 6), I'm bagging my clippings this year as the sod farm recommended. Next year and beyond, I'll mulch my clippings as I always have...  This is the blade I ordered and I'm very satisfied with it!!
