Unwanted scalping and striping by Ego self propelled mower.

My self propelled Ego sometimes seems NOT to be revving up enough to cut thicker Bermuda grass then seems to bog down into the grass runners scalping the grass. The mower also cuts stripes by cutting the grass shorter in one direction then longer in the other direction. Weird. I do cut on inclines but not what I would call steep. I have cut in all directions on the inclines but lately I can't do that without scalping the grass. I use a slower self propelled setting. Second season of cutting. Old Toro did alright before dying.

Are you bagging or mulching?

Mulching. No bagging.

I also had the problem with the stripes of grass almost Mohawk looking lines. What I did was over lap my passes by a few inches. What size battery are you running?

Battery is the big one that came with it.  I also noticed the mohawks and did overlap but that only solved the mohawks not the other. I'm beginning to think it's not revving up properly sometimes and trying to cut thick grass at normal speed causing it to bog down into the grass instead of high rpm's to cut the top off.

21” self propelled, correct? I had the same problem, although I was intentionally scalping my lawn but when I cut normally I have no issues with the low revving. I know it’s a pain but when the grass gets too high you could cut at let’s say deck 3 and then drop the deck to 2. I also have thick Bermuda.

Yes it's a 21" self propelled. I always cut at the third level high. I cut the grass on Fridays and Mondays so it won't get to high. I'm taking it in to a Home 
Depot tech next week after talking to Ego support. I don't think it's revving up like it should. When it does rev up it cuts fine. Thanks for your help.

What's your height of cut you're trying to maintain?  You may not be mowing frequently enough.

I cut at the third level. I cut on Fridays and Mondays. If that's not enough cutting then I'm quitting and living under a bridge homeless.

Also usually scalps grass going down an incline. When I say scalp I'm talking about cutting the grass shorter browning it. The troubles are usually on the inclines and not on level ground.

Try using the new 21" uplift blade and go slower with your lawn mower.  It made a big difference in mulching our lawn.  Also, don't cut any lower than 31/2 inches, which is the fifth level on the self propelled lawn mower.  The longer the grass, the longer the roots and the healthier your grass will be.  Good luck!

I thought of doing both of your suggestions. I have bermuda so I think third level high should be alright. If I cut it higher I'll never be able to cut it lower. Found out that Home Depot techs can only fix something obviously broken on the mower. My problem isn't obvious. Therefore they will have to send it off and I can't be without a mower for weeks. I'll most likely borrow a gas powered mower and see if it does the same thing to rule out the Ego as being the problem. Also will try another blade. Thanks.
