      Hello Bobb! This unit does not offer a side grass catching bag, I am so sorry for the trouble! Thank you for your question!

        3 position height adjustment, take off each wheel? You are kidding? I am not lazy, but if I need to adjust cutting height and take of wheels each time I will not worry about it be cause I will not own one. Todays mowers have auto adjustment.

          When I took out of box and unfolded handle, the handle is not sitting in the grooves so it cannot lean back. I do not see how to get the handle into the grooves, it came already fastened and it is not the kind of bolt I can unscrew and I do not see how to

            Because it’s $299 junk

            By|Feb 24, 2026

              I guess because it is a newer model maybe? I don't know but I wish there were more reviews, pictures, videos because I cannot get the handle right. I know others can do it no problem but I am not those people, lol.

                  Ok mower
                  Delivered extremely damaged. Oil leaking everywhere. Bent handle, no gas cap, missing hardware. Took old hardware from older mower to put it together. Also used old gas cap from older mower but it doesn't fit. Not HDs fault but whoever ships this out should definitely package the product better. Opted not to haul back to store for replacement . Gassed it up and it works. A discount would be appreciated.

                    Lasts about a year!
                    Bought 14 monthes ago and supposed to have 2 year warrantee. Mowed lawn and was just ready to turn off when started to smoke badly with clouds of smoke. Turned off and put it in garage. Few hours later saw pool of black oil on cardbard at left front. Called Home Depot and told to call Troy Built. Called Troy Built and was told to call Briggs & Stratton. Brought to service center for Briggs & Stratton but was told they tould give estimate but Briggs & Stratton would probably deny coverage for repairs and make excuse for operator errror. I would not buy this lawn mower unless you want to replace it in a year. Terrible product and even worse customer service from all p[arties. Will not buy from Home Depot after this.

                      So far we are pleased with the performance. The engine is just right for our front yard and our back yard. The mower handles well.
