I received my mower yesterday...got it oiled up and gassed up...put the handle on it and off I went. It runs really well easy to push,but the handle knob fell off( I could not get it to tighten) and I mowed over it...so out of the box ,throw the handle knobs away and put you a bolt ,washer and double nut on it or the handle will fall off.. I give it 3 stars for that reason..5 minutes and have to fix something,not good! The rubber thing at the back of the mower stays under the mower,I just left it , the blade didn’t hit it..the reason I would recommend this mower is because it does run good and easy to push.but put some good bolts in it first...honestly I don’t look for it too last long.

    Simple to use, power to spare.
    [This review was collected as part of a promotion.] The Murray 21" Cut Gas Push Mower arrived just in time as the weather was turning, the grass was lengthening, and my old mower had died at the end of last season. Fortunately the Murray is doing a fantastic job, and making my time tidying the lawn less of a chore. Out of the box you only have to straighten and tighten the bolts of the handle, slowly pull the starter cord to place in the spiraled metal housing, fill with the included oil, and fill with gasoline (not included, obviously). This took literally 5 minutes and I was ready to go. It may take a minute or two more if you want to install the grass shooter on the side of the body, but I prefer to mulch my grass, and that’s how it was installed in the box. There are 6 levels to choose from on deck height, or rather 12, as both the back and front tires have the ability to be adjusted. After 3 squeezes on the bulb to prime, I pulled the lever, then the cord and the Murray started without issue. The engine was steady and strong, and the lever was easy to hold in place. Because the back wheels are so large it is easy to maneuver, which i appreciate as my lawn is far from even or smooth. When I killed the engine going over some too tall, damp weeds, it responded immediately when I started her back up. The engine sounds are consistent and without labor. My only very minor quibble is the placement of the priming bulb. It is on the opposite side of the starting cord, so you have to reach across the mower to prime. I know nothing about engines, so this may be necessary or standard, but I would prefer they were on the same side. That said, it certainly doesn’t give me pause in recommending this mower even the slightest. The mower looks pretty cool too, if that matters to you. It has a silver finish, with black and red accents. It seems to be very well made, and of good balance, and quite sturdy. It doesn’t rattle or vibrate to excess, which is a sensation I really can’t abide. It has good power, and doesn’t require much overlapping when trimming the yard. I anticipate this lasting for a long time, and I’ll certainly be happy to use it. It is easy to use, reliable, and looks great too. I do recommend!

      Very sturdy and durable
      [This review was collected as part of a promotion.] I finally had the chance to use my new Murray gas push mower for the first time since having it. It was easy to put together right out the box. I used the quick start guide included in the packaging to get started before using the mower. I had to add the gasoline and engine oil to the mower before I could use it. A Quick Start Guide was included in the packing to get me started. The packaging also included some engine oil for the Murray mower. It came with all I need except for the gasoline. The Murray 21" 2-in-1 High Wheel Push Mower is a high-quality product with a 125cc E450 Series Briggs & Stratton engine. I am a fan of Murray and Briggs & Stratton. The Briggs & Stratton engine is reliable and powerful that cut through the thick grass I had without a problem. I like that the rear wheels on the mower are high. That way it, makes it easy to handle on a hill or uneven terrain. It is a reliable mower that is sturdy and durable. I am impressed with all the features this Murray mower has. The easy-to-start featuring the Prime and Pull, 2-in-1 cutting deck to mulch (mulching plug included) or use the side discharge, dual-lever height adjustment with six grass-cutting settings, 21" Steel cutting deck, and a dependable 125cc Briggs & Stratton Engine. It does a great job mowing my half-acre lot. I highly recommend this product. It comes with a 2-year limited warranty too. I am impressed and overjoyed that I have this excellent product. What a way to start my mowing season out. Truly pleased!!

        Lightweight but Powerful!!
        [This review was collected as part of a promotion.] This 21" Murray Push Mower came almost completely assembled, which was really convenient. The instructions were very clear and easy to understand. It also came with a container of oil, which was a plus and it was easy to fill. I've had this mower for about two weeks and haven't had any issues. It has started on the first pull everytime and runs great. I really like how easy it is to maneuver, it makes it easier to get between and around things in my yard. This lawnmower may be lightweight, but the engine is powerful. This lawnmower also has 6 different height adjustments and it is easily adjusted, with just two levers. My favorite feature would definitely be the option to switch between the side discharge and mulching function, depending on the height of the grass. This Murray Push Mower leaves my lawn looking fresh, with a nice, even, clean cut.

            Nice product
            [This review was collected as part of a promotion.] We received the Murray 21" Cut Gas Push Mower and my husband put it together with all ease . We can't use it right now due to coming out of a ice /Snow Storm. Very durable material it is made of . Only one fault we have with the lawnmower is that there is no drain hole for the oil . You have to turn it completely over to drain . Other then that it starts with just one pull of the cord !!

              Nice Lawn Mower!
              [This review was collected as part of a promotion.] This is a really nice, basic lawn mower. Briggs & Stratton motor (made in the USA so that's a plus), 21" mower has 2-in-1 mower/mulcher side discharge cutting deck with an easy to install piece to blow mulch/cuttings out the side of the deck. A flap in the back will keep cuttings from blowing all over your feet and legs. Dual level height adjustment, controls lift both sides at once. One for rear wheels, one for front wheels. 6 levels of height adjustment, on the highest level there is plenty of clearance to whack through some thick and unruly growth. Seems super maneuverable with an easy pull start. Mower comes almost fully assembled, you only have to attach the handle together. Comes with all instruction manuals and a quart of oil. Unfortunately, I live in Maine and my lawn is currently buried under a foot of snow, so I haven't been able to use it yet, but I am really happy with the quality, construction, and features, and I am looking forward to using this mower!

                Starts on First Pull
                I have used this Murray lawn mower twice since the initial purchase and both times it started immediately on the first pull. The construction appears to be fine for an average size residential yard. The 140 cc Briggs & Stratton engine has the power (torque) to cut through tall and/or wet grass without difficulty.
