Solution to Trailing Shield Breaking off on 21" Mowers

Earlier I reported the trailing shield broke off on 21" EGO Battery Mowers (after three mows).  EGO sent a replacement shield quickly - under warranty. 

Solution from this forum to use metal rod rather than supplied screws worked perfectly to reinstall the old shield. 

However, on further investigation, the trailing shield still buckled during mows, causing further stress.  The issue is that the designer made the shield too wide (in the vertical) and it would only perform properly when cutting grass to a very high height (eg setting "6").  I suspect most users use setting 3 or 2 for much shorter grass.

Therefore, simply cut off enough of the shield so that it just drags the top of the grass for your most common height setting.  When backing up, it therefore does not buckle and the attachment points to the mower are not stressed.

Yes, I just experienced the same issue with the trailing shield after 3 mows.  Will contact for replacement.

As mentioned it is too wide.  Probably you are safe to cut up to half of it off.  And don't toss the old one.  Take a good strong metal coat hanger, made perfectly straight in the vice, then add a small right angle at one end; poke it through the old screw holes and the entire length of the top part of the trailing shield to the other end.  Cut off the hanger there and just bend it carefully about 45 degrees (no need to try to make it 90 like the other end).  This will hold it in; the ends clear the wheels by a lot and the 45 degree end will be easy to straighten out with pliers when you are ready to install a new shield.
You will have the right size when it does not catch the ground or buckle when you need to pull the mower briefly backwards at the end of a row.

I'm in the market for a battery mower.   Think I'll wait for an upgrade

Maybe an idea.  My surveying told me EGO was one of the best so that's why we went with it.  Main issue might be too much plastic, but functioning except for the 'trailing shield" has so far been excellent.  It has six cutting heights and the one you use depends on a lot of factors and the type of cut you get and how the lawn looks for days afterward is related to how long or short you leave the grass.  Here in the hot East, it is now better to not cut too short to reduce browning.

Calling for 95F again today, 115F with humidity, here in Ottawa. Near record temps. I’ve been cutting my grass on the 20” mower’s highest setting ever since I started fertilizing, and one of the benefits is how drought resistant the lawn now is. We water our plants but barely ever need to water the lawn.

I'm in Ottawa too.
The high setting (6) would leave very long grass and you would have no trouble with the shield.

I`m using setting 3 - the middle one and mulching, and our lawn is greener than the neighbours who are cutting IMHO too short for these conditions.  Over a week now too between mows.  Never water the lawn either and it is a no fuss one so I dig out dandelions in the spring.
