        A:  I ordered mine from Home Depot and they were delivered in a couple of days. If you have the zero turn with the 42 inch deck, these are the blades you’re looking for!

          A:  I just went on home depot's website and ordered the blades listed for my mower; ryobi 48v zero turn

          by|Aug 21, 2019

          A:  These blades are out of stock everywhere. This is unacceptable. A $30 set of blades render a $4,000 mower unusable. Need to take mower back for a refund and purchase a product with readily available parts.

            A:  2020 spring season - out of stock since the grass has started growing! Unacceptable!!! These things are so flimsy they take a root and are completely done. Normal mower blades pop back in a vice and your good to go. If these get off canter the slightest bit there battery dive bombs. You MUST look into stocks ng these or hand over to a 3rd party that can stamp metal for you if your having a shortage. If anyone is aware of any aftermarket that fits - please post.

              A:  Look it up by part number or model number on home Depot website or app

                  A:  I'm in the same boat. They said just wait for them to be available from Home Depot is what I'm told.

                    Q:Which set of blades is for side discharge? The one that says bagging blades say side discharge in the description.

                    A:  Mulching/side discharge blades, not bagging blades. Order two sets to get free shipping.

                    by|Sep 2, 2020

                    A:  If you are NOT using the Side Discharge Bag Attachment, than you WOULD USE these blades (Internet #309693621 / Model # ACRM006). I use these blades because they are "mulching" blades and work well with the mower's side discharge; or, like I do, with the side discharge plug installed for mulching the cut grass. You will easily notice the design difference between the "mulching" blades and the "bagging blades" (Internet #309740731 / Model # ACRM007) because the "bagging blades" have a more pronounced turn-up to the end of the blades; which, I'm guessing, helps insure the grass gets thrown out of the mowing deck area with sufficient force to carry the cut grass to the bagger. I'm assuming that since the "bagging blades" are NOT "mulching blades" that if you use the "bagging" blades without the bagger attachment, that you'll get full cut grass discharging a good distance across your lawn, waiting patiently for you to rake. Hope this helps.

                      A:  Hi, Jlh035- These blades are optimal for mulching/side discharge. The bagging blades are ACRM007. We hope this helps!

                      by|Jun 14, 2019

                        A:  According to Ryobi this is the blade the mower comes with. So it’s the discharge / mulching blade

                            Metal is thinner than original blade metal, but works ok
                              The blade fit perfectly and was actually a Ryobi product. The blade did not require balancing. went back and bought another pair for next year maintenance.
                                  Perfect fit and get faster cuts now that I've got new sharp blades installed.
                                      These are the correct size for the 42" cut. Don't get the 10" blades like I did. They will fit but They miss cutting a strip in the middle (imagine that, lol) . I sure did not think they would make a 40" and a 42" in an Electric Zero turn. These blades are thinner than a typical 42" riding mower blade. That is because the electric motors go faster and need a lighter blade, I guess. But net result is these will get bent and dull easier than a typical riding lawn mower.
