    Answer This Question

    A:  The response by Milwaukee Tool is incorrect; The handle bar has three positions of height adjustment. The length of the handlebar is not adjustable, however.

            This is a cheaply made toy
            I’ve only used this mower about four times. My son wanted to help mow the grass and he accidentally hit this extremely small stump, pictured below, with the mower and the motor completely ripped out of the mower deck. The mower deck must be made out of some kind of plastic. For a top-of-the-line mower of this price tag, I think this is ridiculous! When I called the Milwaukee customer service, they said that I had to drive it to a repair center before they could let me know whether or not it would be covered. This repair center, which doesn’t take phone calls, is between one and two hours away depending on traffic. After much pleading, she finally agreed to find out if it would be under warranty. After sending her the pictures below, she said it would not be under warranty. I made the investment in this mower because I thought I would have it for many years, and I got about four uses out of it. I have a ton of Milwaukee tools I like, but Definitely avoid this mower!!! It is more of a toy than a lawnmower.

              This thing is an absolute monster. With my old gas mower, I used to not be able to mulch while mowing without bogging down my mower. This mower handles with ease. I mow about 1/3 acre only using half battery life on the highest setting.

              Milwaukee Warranty is a pain
              Need a replacement part (28-41-0018 rear guard service kit). Only way to get the part replace free under warranty is to take the entire lawn mower to a service center. This is a major pain to pack up an entire lawn mower for a simple part that can be repaired at home with 3 screws. This isn't a hand tool I can easily load into the back of my vehicle. I know Rigid will sends replacement warranty parts free by mail so I would reconsider this purchase if I were you.

                No suction
                This spring there was huge dead patches in my beautiful new sod lawn, I contacted the turf farm because I had used all the recommended fertilizers brand new topsoil and sod, I showed them the pictures and they said it was caused from the mulch left from the mower not picking up, we always used grass catcher and we cut on #3 height on high vacuum then mowed it twice each direction once a week to get any leftover grass that was uncut. I mow my entire lawn (100’x70’) and get a handful of clippings

                  Yes please, can I get another!
                  Where to start, right off the bat it came with 2 M18 12amp batteries! The mower has sufficient power to mow my 1/4 acre yard and still having 2 bars left. I bought the mower so my kids can help mow when I’m at work and it delivers the power and ease.

                    The Mighty Have Fallen
                    Remember when Milwaukee stood behind their products? Those days are over. I purchased this mower at my local Home Depot in September. There was no bag of hardware or parts to assemble it anywhere in the box. I contacted Milwaukee four times. When I did get someone to help, I had to look up every part for them because they wouldn't do it. That was September 27th and they promised the replacement parts would go out that same day. I'm pretty sure they didn't send the parts. I had to buy my own.

                      Blade fell off when starting motor!
                      After 4 weeks of using the mower, the blade came off when I pushed the start button and it dropped in the dirt next to the mower. I emailed Milwaukee tech support on Tuesday. They claim to respond within 48 hours. By Friday, no answer. I called 1-800-Sawdust. Customer service told me the tech support guys already went home. (It was still business hours). I normally buy power tools from another brand but this expensive mower had convinced me. Now I am not even sure whether it is safe to use.

                        Don't waste your money
                        The lawn mower was easy to setup and comes with two giant batteries but it pretty much stops there. This is a $300 mower with batteries you can use with your other tools. While mowing the mower hit a piece of metal and the motor housing fell off rendering the mower a piece of lawn art. Milwaukee now is servicing mower for $400 and the mower will only be used to mow pristine fairways at Augusta now. The LED lights are cool.

                          Mostly great but with a fatal flaw
                          This mower has plenty of power and cuts well. From the 2 times I was able to use it before it self destructed it seems like the battery is great. Its fatal flaw is that the housing for the electric motor is entirely made of cheap plastic. This means the second you even graze a small rock on your lawn the motor will separate from the mower. Thankfully I was on flat level ground when mine broke and it didn’t cut one of my legs off in the process. Definitely cannot recommend.
