My lawn mower  leaves a whole six inch patch in the middle of the cut!!! So between the wheels...it will cut eight inches on each side...WELL then there is a whole patch of grass not cut!!! I have tried everything.  Moving side to side, mowing criss cross...mowing slow...mowing fast...using the self propelled...not using the self propelling...It's like getting a mohawk haircut!!!  I just replaced the blade...nope! Still a mohawk!  It is not tall grass...not heavy grass..it's grass.  I even tried a new blade.  Nothing has helped!

Is your deck totally clean?
Are you mowing at WOT?
Have you sharpened your blade? And is it balanced? 

Finally, is the blade properly aligned on the mower? (Not installed upside down)

totally clean.
what's WOT?
I'm assuming factory blade was properly installed correctly...I have JUST bought a new blade and installed per the directions.  Thought maybe new blade might help...just makes it more pronounced!
MOHAWK...thanks!!!

I can only hazard to guess that WOT is "Wide Open Throttle", meaning the motor is running at speed. Seems like the only thing that would do what you are describing is the blade installed upside down. (And yeah, I think it's possible that the factory installed a blade upside down on very rare occasion.) The bulging embossment stamped into the blade should be facing down toward the grass. I think the blades even say "This side facing the grass". Sharp and balanced as Paul said is also important.  Good luck!

OK!!!! AFTER further review!!!! The blade was on upside down!!!  I put the blade back on exactly the way it came off...so it came to me that way.  But we took apart again - put the blade back on and I just tried it!  NO MOHAWK!!!  I am so excited!  I've been living with the mohawk for two years now! Lesson learned! Double check the factory installation!

If your mower is an EGO, it was built in China, and Chinese quality control is notoriously spotty.  And not only for EGO products.  I have radio gear whose capabilities were greatly restricted for some time before my eyeball exam revealed several bad solder joints.  Luckily, these were easily repaired as they were discovered.

Keith, Quality Control is as good or as bad as the company wants it to be regardless of where their factories are located.  Most of the world's most desirable electronic devices are made in China and have very good track records.  Some of the least reliable products in history have also come from China.  It's also entirely possible to make terrible products right in the USA.

There was a time where things made in China were on average far less reliable than products made elsewhere, but that time has passed.  If a company wants to make good products they most certainly can, and they can do it anywhere.  It's just up to them to properly manage their QC.

Same thing here. Also, one direction cuts lower and the other direction cuts higher mowing up or down or sideways on slopes. Don't ask me how. I had to overlap thereby causing me twice the time to mow and charge battery. I've tried everything. Will take it in in late fall when I can afford not to have a mower for 6 weeks.

Is this a sloped area ?
Have you tried applying some upward pressure on the handle to make sure the front of the mower is not lifting up as you push or go over bumps ?
Have you checked the blade for proper installation and sharpened it.
