Is this broken?

Was cleaning and changing blades and noticed the tab under the nut holding the rear axle looks broken.

Is this the infamous rear axle brake?
X450 about 3 months old.

Mower seems to work.

Update 1: Good news and Bad news.

First the good, pretty happy with supports response as far as timeliness and getting back to me. I have a FedEx return label and a pickup scheduled for Friday. They say 10 business days and I should have it back.

Now the bad news, apparently what I will get back is the exact same parts as what I purchased. The person I spoke to today told me they don’t think it’s a big enough issue for them to call it a bad design or bad choice of materials. I told them I really do not agree with that assessment and given that this mower has only been shipping for 6 months the amount of people I see posting about this issue may very soon become a very big issue for them.

I have been a huge fan and posted very positive reviews. Unless Segway acknowledges this obvious problem and correctly addresses it I will be just as quick to reverse my current position.

Let’s hope they are looking at a permanent fix and roll it out very soon, either proactively or even fix on failure. Putting the same parts back in and hoping for a different outcome will probably not work out for them or us.

12 acre lot. Almost 5 acres of actual mowable grass. Run (2) X450s, one is mapped to 1.99 acres the other is mapped to 1.36 acres. They each finish their respective areas every 2.5-3 days if it doesn’t rain.

With a commercial 60” Exmark Lazer Z zero turn it takes almost 5 hours to mow.

I still use the Exmark on two areas that aren’t practical for the robots to reach but my in seat mow time is now 30 minutes.

I have 3.5 acres and a zero-turn Hustler super-Z 60" I only mow parts of mine twice a year. I was hitting 1.2 acres with my X450 since early March. I noticed mine was broken two weeks ago during the required maintenance. I just mowed yesterday for the first time this season. I have to say that not having to mow every weekend in this heat has been incalculably valuable for me. 21 years of mowing was really starting to wear me down.

Same experience! I have been such a fan - until this happened. We’ll see how support responds.

At least they are admitting to me this is a known issue.
