          can it self propel up a 6-step stairway?
          ByAug 16, 2026
          1 Answer | 
          Answer This Question

          No. The self-propel system is designed to drive the mower across lawns and slopes while the wheels remain on the ground. It is not designed to climb stairs or pull itself up a 6-step stairway.

            how does is catch the grass- does it fill the bag i have a gas toro and the bag only fills 1/4 full before it leaves clipping on lawn
            ByAug 16, 2026
            2 Answers | 
            Answer This Question

            It does fill the bag. Will continue to try to keep filling it also even when full. Do not recommend this mower.

              (1)

              The M18 FUEL Brushless Cordless 21 in. Walk Behind Dual Battery Self-Propelled Mower (Tool-Only) uses a high-lift airflow design to improve grass collection and bag filling. If your Toro leaves clippings with the bag only 1/4 full, the Milwaukee's High Lift Mode should provide noticeably stronger grass collection.

                How are the tires on steep hills? I am planning on upgrading from the 4wd ryobi as the tires are plastic and spin on grass hills.
                ByAug 5, 2026
                1 Answer | 
                Answer This Question

                The M18 FUEL 21" Self-Propelled Mower handles steep, grassy hills better than plastic-wheeled models due to: High-traction rubber overmold wheels (not plastic), which grip turf much more effectively. Variable-speed self-propel drive for consistent control uphill or downhill. Brushless motor + twin M18 batteries delivering steady torque under load.

                  Milwaukee do not stand by this mower
                  Mine lasted till just beyond warrantee!!! Handlbar main power switch, which is designed to trip via the bail arm has broken and will not stay depressed whether or not the bail arm is engaged. So I use a Dewalt 6" clamp to hold the switch down, which is clearly dangerous. Milwaukee could not have been less helpful... 1. This is clearly a defective part given the amount of communication about it on the internet 2. This is part of the product safety system so should warrant additional care and attention 3. For such a costly product relative to peers, at least double the price of competitors, it should perform better than this 4. There is no switch only available as a spare, only the whole handlebar assembly, at close to $300 5. There is such demand for this defective item it out-of-stock in most locations Overall this has significantly soured my experience with the brand!

                    Was able to mow my whole yard with one charge. Grass was high and wet and didn’t stop it or bog down at all.

                    It's pretty good.
                    It's pretty decent. It's expensive, but it is high quality. My property is small 50ftx 130ft in and small town and my house eats up half my real-estate. The m18 mower has good power and with the two 12.0ah forge batteries It's runtime has been above my expectations. I can mow my front and back yards 3 times before I am at one bar and charge the batteries. I dont use the bag, (kinda feels cheap) I have always mulched and it seems to do that really well. I give this mower 5 stars cause it feels like it will last a long time and I no longer need to worry about gas, oil or filters.

                      Battery Bait & Switch
                      This mower is advertised as coming with two 12ah FORGE batteries, but the actual item contains 12ah HO batteries. When I contacted Home Depot about this, they directed me to talk to Milwaukee. When I spoke to Milwaukee they said it was a Home Depot issue. I’m very frustrated with this issue.

                        Could be more resilient!!
                        I have purchased two Milwaukee lawn mowers in the past 4 years. Both were rendered unrepairable after hitting a dog toy and a tree root, respectively. I recognize our error of not being more careful; it also feels bizarre and unfortunate that one bad contact can brick the mower. This particular result is not uncommon. I am a committed Milwaukee tool owner; I have over 2 dozen M18 and M12 tools and a full set of pack out containers. Please replace my lawn mower and make them more robust.

                          Great until the $5 part falls off the handle. To get replacement you have to spend $50 …. What a joke for this over priced junk. Out on this line … He

                            Best lawnmower I have ever owned and 1st battery powered mower. I was hesitant on the width as I have a 1/4 acre lot but the power and speed of this mower actually reduced my cutting time by 10 minutes. Ignore the negative comments about the blade. This mower provides an excellent cut! I have been using the mower for 2+ months now. Zero regrets on this purchase.

                            Wheel issue
                            I recently purchased a Milwaukee M18 battery-powered lawn mower and was genuinely excited to add it to my M18 tool lineup. Unfortunately, the unit arrived in a damaged condition that prevented safe use right out of the box. Upon unboxing and attempting assembly, I discovered two significant issues. First, the front left wheel was visibly misaligned the deck frame was pressing directly against it, preventing it from rotating freely. This is not a minor cosmetic concern; a bound wheel directly affects the mower’s ability to track straight and would place undue stress on the deck and drivetrain during operation. Second, and more concerning, a closer inspection of the same wheel revealed that the plastic housing was cracked. This is a structural failure, not surface-level damage, and it raises serious doubts about whether this unit was properly inspected before being packaged and shipped. I want to be clear that I am a loyal Milwaukee Tool customer and have invested significantly in the M18 platform. This experience was disappointing not because of the product design itself, but because of the quality control failure that allowed a visibly damaged unit to reach a paying customer. At Milwaukee’s price point and with their reputation for durability, this is simply not acceptable. I would strongly encourage anyone purchasing this mower to thoroughly inspect all four wheels including the plastic housing before first use
