Questions & Answers

Will this fit a ZT480EX riding mower?

Answer This Question

The answer from Ryobi is confusing at best. Yes, the blades are for the ZT480EX which is the model: RY48ZTR100. I have that same mower. Have you done the conversion to the (Lithium Iron Phosphate - LiFePO4) batteries? It's a game changer for these models.

                  5/28/19 I managed to damage a blade and need a replacement. I've played hot potato with the RYOBI "Parts/Help" phone number a few times. Given the wrong part number and no way to order now. Anyone have better luck?

                  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!

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

                      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.

                        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.

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

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

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

                                By|Sep 2, 2020

                                  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.

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

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

                                        Semi good mower
                                        [This review was collected as part of a promotion.] Really nice mower, but unfortunately, it takes lots of attention and maintenance. The catcher bag is fairly flimsy. The batteries don’t last that long and they are very expensive. Ended up switching to lithium and had to do some rewiring and adding a resistor and momentary switchfor startup. Also, the blades are very flimsy and you will go through them fast if you start hitting rocks or sticks or even pinecones. They bend and dull. It will cut an acre of grass very nicely on one charge. When the original lead acid batteries that came with it, I would be able to do the whole acre with 75% power left. Eventually, that diminishes to the point where the batteries are no good. The wheels in the front sometimes dig into your grass when you make two chop turn and creates divots. I think Ryobi has a lot of adjustments to do to make this lawnmower better. I gave it three stars because I don’t have to buy gas or oil.

                                          Blades are weak and bend easily
                                          [This review was collected as part of a promotion.] I have gone through 2 sets of blades this in less than a month, bending them when they hit uneaven ground (ground mole trails) and fairly soft dirt. Ryobi better make stronger blades.

                                            Perfect Fit and Great Cutting Performance Product: Replacement Mower Blades (Fits Ryobi RM480e / RM480ex & 42-Inch Zero-Turn Models)
                                            Pros: Exact Fit: Fits perfectly onto the deck spindles with zero slop or alignment issues on both the RM480e / RM480ex and 42-inch decks. Cut Quality: Delivers a crisp, clean cut across the entire lawn without tearing the grass tips. Lift & Airflow: Generates plenty of airflow to clear clippings smoothly out of the side discharge chute without clogging the deck. Easy Installation: Swapping out the old set is quick and straightforward once the deck is accessible. Cons: Edge Prep: Like most factory or aftermarket blades, giving the edge a quick touch-up with a file before installation ensures maximum sharpness. Bottom Line: If you need a reliable set of replacement blades for your RM480e, RM480ex, or 42-inch zero-turn mower that drop right into place and restore your mower's original cutting performance, these are spot-on. Highly recommended for keeping your lawn looking sharp!

                                              These are good blades, and they are OEM.. Im my opinion they would be a bit better if they were a little thicker. I understand that they are trying to keep the weight down to extend the battery life, but if they were a bit heavier, I think that a little bit more weight would make them more durable. I
