About This Product

Introducing RYOBI's first lithium-ion battery powered zero turn riding mower, the RYOBI 80V HP 42" Lithium Electric ZTR. HP Technology and 80V batteries combine to deliver the power equivalent of a 31 horsepower gas engine*, while eliminating the hassle of a gas mower. This rider cuts up to 3 acres per charge with 4 brushless motors, (2) 80V 10Ah batteries, and (2) 40V 12Ah batteries, with a Super Charger that fully recharges in 2.5 hours so you're ready for your next job. The revolutionary iDrive system uses an intuitive one-handed joystick steering to maneuver around objects more easily than a traditional ZTR. The innovative LCD screen displays runtime, battery life, and more, while the Riding Mower app allows you to monitor charge time and battery life remotely. This riding mower features the CROSS CUT multi blade system, providing superior cutting & mulching performance and a 12-point height adjustment to select the perfect cutting height between 1.5" and 4.5". This mower continues to lead in innovation with the compatible Bagger Boost accessory, which quickly clears the chute with the press of a button, and the rubber side discharge chute makes it easy to maneuver around landscaping. Designed with convenience in mind, this mower features premium seat suspension, 2 USB ports to charge phones, a storage compartment, and LED headlights. Lawn maintenance will never be the same thanks to the RYOBI 80V HP Brushless 42" Lithium Electric Zero Turn Riding Mower.

      Q:I have a brand new 42 inch for Albee. Lawn mower has never cut grass due to the blades, not staying engaged over 3 seconds. Jacket.
      by|Jul 8, 2024
      1 Answer
      Answer This Question

      A:  Hello, Greg - We're sorry to hear about the blade issue. This may occur for a few reasons: 1) The battery charge is low, so please ensure the batteries are fully charged. 2) The blade engage knob is down, so please raise it. 3) The operator is not fully seated. If that's the case sit down fully on the seat, return the joystick to the neutral position, and push the blade engage knob down. Then try again. If these suggestions don't resolve the issue, then please contact us by phone or text at 1.800.525.2579, Monday - Friday from 9 am to 5 pm (EST), or via email when you visit us at https://www.ryobitools.com/support/contact.

        Q:Why does my mower keep turning off even when the batteries are at 100%?
        by|Jul 7, 2024
        1 Answer
        Answer This Question

        A:  Hello, Claudia - We're sorry your mower keeps shutting down. This may occur if the cutting height is set too low, so raising it may resolve the issue. Also, if you're not fully seated in the seat, this may also cause the mower to shut down. If neither of these solutions resolve the problem, then please contact us by phone or text at 1.800.525.2579, Monday - Friday from 9 am to 5 pm (EST), or via email when you visit us at https://www.ryobitools.com/support/contact.

          Great mower, excellent price.
          I was able to get one at an excellent price thanks to Mike, Jorge and Isabel. They were also able to find the two 80V batteries without it there is no way it would work. It was delivered as promised in a week and the delivery went without a hitch. As a display unit it shows signs of wear and the lid for batteries does not stay closed. But it works and mows the lawn perfectly. The joystick is something you will take a day or two to get used to. A big shout out to the lawn team at Dale City HD.

            Disappointing Quality
            The Ryobi 42 Inch 80V Electric Zero Turn Riding Lawnmower fell short of expectations due to its rusted and faded parts, cracked plastic components, and missing batteries and chute. These issues indicate serious quality control problems that need to be addressed. Based on my experience, I cannot recommend this product until these concerns are resolved.

              Very disappointed in Home Depot / Quality Control
              Home Depot is terrible. This machine is rusted all over, I did not get a manual because they said they threw it out along with the tools I was supposed to get. I only got one key.. There is a bolt missing from the left armrest, there was a bolt that fell out of the towing plate which thankfully I was able to grab and the battery hatch doesn’t even have the hook on it to close! I cannot close my back battery hatch. Ryobi, can you make this right??

                Had for over a month now. Cuts great. Get about an acre done with 30% battery left. Love being able to control with one hand and have tthe other free for drinks. Not happy that it got delivered jn the rain uncovered, soaked, and sloppily assembled. They also ran a Memorial Day sale a week after I bought it offering a free bagger, They would not honor that. Told me I would have to return it and rebuy it to get the bagger. Joke customer service for such a big purchase. .

                Be aware
                I bought this supposed to be new and 2024 model was sent last year’s model as evidenced by the USB one amp charging port Batteries looked old mower, looked like it was out in four seasons Very weathered. also, the delivery man Had no forklift .I did receive an email that they were sending me a” Bruised and reduced” Item and maybe I could call and get some money off. Unfortunately, I didn’t see the email before delivery. So now I’m waiting for the exchange…. Stay tuned

                  Weak metal parts and Ryobi provides no support
                  The spindle heads where the blades are attached are made of some cheap pot metal. The pins will break leaving you unable to securely attach the blades. I have mowed my yard less than three times. Once you contact Ryobi for replacement parts they will promise to call you back but not do it. With broken parts and no service you won't be mowing.

                    Cuts 3 Acres - NO WAY - I have 1.6 acres (including house and long driveway) and this couldn't cut half of it. Tried it again with different height adjustment, drive speed, and cut speed and had the same result - 1/2 of the yard. Flat yard, grass was thin and spotty so there isn't a solid reason why this can't handle <1.6 acres. Is it a bad battery? They 80v looked used when I received them and had damaged handles

                    bad product or bad service?
                    The tractor “New” look like an used, and nobody is worried about that. I will test it but I think I will return it asap.

                      Liked it but didn't want to burn down my house
                      DO NOT buy this online. Go to a store. The delivery experience was bad. The return experience was worse. Battery overheated during charging. Ryobi support didn't seem concerned. Guess responsiveness to battery issues is reserved for YouTube influencers. Charger tripped the GFCI even when not connected to the mower. THD would not exchange the mower or extend the return period to troubleshoot so I had to return. Would provide a lot more detail but THD limits reviews to 500 chars.
