Q:If I use the bag, is this mower capable of picking the gumballs from sweet gum trees.
by|Sep 16, 2023
1 Answer
Answer This Question

A:  Hello, Joew - Thank you for your question. The mower would not be designed to pick up gumballs, the blade and grass bag are designed to lift, deliver and catch grass in the grass bag.

        WARNING - Cheap and Dangerous
        This is the second season I've owned this. It hasn't been used more than twenty times. Today I hit a rock or stump, and the photos explain the rest. The blades are connected to the motor using three square washers, so when the metal failed, it did so in a perfect square. I've never seen anything like it. Cheap and dangerous.

          Over the 20 years I have lived in my current home, I take great pride in mowing and manicuring my large lawn. I have experimented with multiple products from Murray to Lawn Boy to Toro and finally Honda. At last I have found a mower that reigns supreme - Ryobi! My new Brushless 21 in cross cut (dual blades) is a breeze! My mower accompanies a Ryobi weed eater and blower. Thanks to these quality products, this 60-something has the “yard of the year” in her community!

              Non Starter
              [This review was collected as part of a promotion.] I bought this mower at the end of September 2022. I’ve used it twice. Now it won’t start. Lights and self propel work fine but the blades won’t turn on. I’ve tried adjusting the folding handles every which way with no luck. There are no repair shops near me. Help!!

                Very Good Performance
                [This review was collected as part of a promotion.] Purchased this mower a week ago and used it for the first time and first cut of the year. Very satisfied with the cut quality using the mulching function. I have a quarter acre level lot and the mower had no problems getting the job done while using one 40V battery and about 15 minutes of the second battery. I love not having to use oil & gas. Hope it keeps us the performance for the whole summer. This mower had minimal assembly and was easy to get going right out of the box once the batteries were fully charged. A few concerns: 1) After purchasing this mower, I looked up how to find its manufacture date and was disappointed to see that it was built in the 20th week of 2021 (Serial # KC2120....). This is April of 2023 which means this mower was built about 2 years ago! It also means that the design/engineering of it was well before that. When a customer buys a mower in the spring, they are expecting to get the current year's technology, not something over two years old. 2) The levers to activate the blades and the self-propelled wheels are a bit sensitive. About five or six times while mowing I released the self-propelled lever but I also must have eased up a bit on the blade engagement lever which caused the mower to shut off. So I had to restart it each time. Not a big problem with the push button start but a bit annoying. I hope as I get used to the feel of the levers that this won't be a constant issue. 3) As some reviewers have noted, sometimes when turning the mower sharply or slightly bumping the side of the mower housing against something (like the corner of the house), the end of the blade hits the inside wall of the mower housing. This I imaging is not good for the blade and can sometimes cause the mower to stall. I hope to get used to handling the mower more gingerly so this doesn't happen as much. Don't know if this is a function of the plastic housing or the blade rotating too close to the housing but it never happened with my old gas powered mowers with steel housings.

                  Blade doesn’t clear mower deck
                  Right out of the box it made a noise when I started the blade motor. The noise was made because the blades do not clear one side of the mower deck. Hard to believe the assembler did not take 2 seconds to rotate the blades to check for clearance. Now I have to return it.

                      DANGEROUS and Customer Service DOESN'T CARE
                      I was happy the first year. In the second year, the lawnmower stopped running when I was mowing. Initially, I could not get it to turn on. I took the batteries out and then put them back in. The mower began working and then three seconds later, about 7 pieces of the blade assembly shot out the right side. Lucky this did not hurt someone. The full circle nub on the hub/rotor broke off because it is plastic. I contacted customer service and asked for a refund. They said no.

                        The best mawer in the market!
                        I've been using many Ryobi products during the last years and this mower do not disappoint. If you are looking for a high quality mower, this is the best option in the market. It's electric but the engine performs like any other gas mower, with less noise and smell. The dual blade really cut the grass with much better precision leaving a more leveled surface . Also, I had some issues but the guarantee is top notch - you just need to contact Ryobi and they will take care of everything!

                          Simplicity! Simplicity! Simplicity!
                          [This review was collected as part of a promotion.] My wife can do it! This mower is so easy to operate that my 5' 2" wife can handle it easily. The push-button start, the quiet-er motor and the self-propelled features are what turns her on. It's relatively light weight too. For me, I love the larger wheels and one control for height adjustment and storage!!! OMG. It stores away so easily. I love it.
