      Q:I had a earlier version of this that I liked and need to replace. One issue was the front wheel adjuster failed twice. Seems to be poorly designed and wanted to know if this has been improved? It was a metal notch that catches to the various heights.

        Horrible so far.
        I bought this mower back in Dec of 23, to be prepared for mowing season of 24. I opened it up a few days ado, now 3/30/24. I assembled it, put oil in it, gas, the common stuff. I fired it up just to make sure it worked, but to my dismay it was leaking oil already within 2 minutes of being on. I turned it to discover what appears to be hairline fractures on the bottom of the motor, incredibly disappointed.

          Easy put together and start!!
          [This review was collected as part of a promotion.] I am a 74 year old woman and was able to put this mower together myself and it started on the 1st full. I am so happy about that!!

          Made of more plastic then they used to be.
          [This review was collected as part of a promotion.] I previously had a TB 110. Hands down the best push mower I ever had in my life. I moved to a new location and decided that I would sell that mower and get an electric mower. That was a mistake. Thankfully I was able to give that to my retired parents, which admittedly is a much easier lawn mower to push at that age and muscle strength status. The electric Ryobi 40 volt is good for flat grassy lawns but no good for pine straw and oak leaves or magnolia leaves. I purchased this mower and at first glance it's pretty much like the TB110. However, I can see several shortcuts mainly involving plastic. And this "check the oil don't change the oil" is the silliest thing I think I've ever heard of. Of course I will maintain an inline fuel filter with shut off valve with good clean non-ethanol gas with the proper enzymes and additives. I expect this one to last as long as the other one would have. But like I said, there are some pieces that are more plastic than metal this time around. Even the side discharge attachment does not have the clips on it to attach to the handles. But other than that, I think I'm going to be very satisfied with this mower.

          Only used the mower 4 times since I’ve had it and it’s doing great so far. Engine doesn’t bog down when I go through the thicker parts of my lawn.(St.Augustine grass).Easy to put the little bit of assembly ( the handle)together and is a breeze to operate and handle.So far so good.

          First time I used it half way through it started backfiring and barely running. I found the butterfly on the carburetor stuck shut and it freed up after I flexed it with my finger. The second time it keep dying as soon as it stared. I shook it and that fixed it(stuck float. Called Troy Built but had time hang up after 45 minutes on hold. Called be and they washed their hands of it and said I need to contact Briggs and Stratton?. Never worked right and now nothing but a run around. Bought this because of the name. Guess that was a mistake!

          I would return the mower if it was possible. As a woman, I am unable to pull start this mower. My male neighbor had to pull start it. Worst $400 I ever spent & NO HOME DEPOT EMPLOYEE will assist me to see if there is a solution.
