54" 115 AH ZERO TURN ELECTRIC RIDING MOWER is rated 3.0 out of 5 by 81.
Rated 1 out of 5 by from Horrible mower due to battery Bought this mower last year. After the first year the battery stopped holding a charge and went from being able to mow 1.5 acres to less than 1/2 an acre. Every time I try to mow after a full charge, the battery dies while mowing (less the. 1/2 acre I ) and battery indicator still reads 55%). Even when using both low speed and low cut, still won’t last. ryobi, You know this is an issue and these are expensive mowers. Fix this issue and fix my mower at your cost not to the customer. So disappointed in Ryobi for making this mower knowing the battery issues.

Rated 1 out of 5 by from Runs on Lead Acid Batteries - Stay Away Definitely stay away from this one. Have had it for 2 years and the batteries have died twice already. Now needing to replace the batteries for a 3rd time already and have not owned it for 3 years yet. This machine is run on Lead Acid batteries which are complete trash. If you have to mow more than 1 acre, you will be able to do it for about 4-6 months and then your batteries will crap out and you'll barely be able to mow anything unless you change them. You'll have a great experience for a few months and then your nightmare will begin.

Rated 1 out of 5 by from Very Disappointed - Too Many Problems I was initially skeptical of buying an electric mower over a mower with a gas-powered engine. I decided to buy this mower because my husband had recently died and I needed something requiring little maintenance that I could use to mow a 1/2 acre lawn. I have been utterly disappointed will the trouble I have had with this mower and unfortunately, cannot afford to buy anything else or replace the batteries. My experience has been so bad that I would give this mower a ZERO star rating if it was possible. The product was delivered in late April 2022. Used it less than a dozen times at my second home. The batteries already need to be replaced after just one year. They run less than 10 minutes at a time! From the beginning, it barely cut my half-acre lawn before the batteries needed charging. There is a problem with the left arm that apparently is known, but Ryobi refuses to issue a recall. The slow-cutting speed option no longer works. Few dealers are available to work on the mower and they offer to send instructions and parts when a covered issue exists. If you cannot get it fixed yourself, then you either have to deliver it to a Ryobi authorized repair shop or pay them to come pick it up. In my case, the closest one is over 2 hours away! This mower cost over $5k and has not lived up to the promises. Ryobi will not replace the batteries because they were out of the one-year warranty (after less than 12). Replacement batteries will be nearly $1800 and I just saw that Ryobi dropped the price of this mower to around $3500. What a joke! This is unfortunate because I have purchased all Ryobi tools and been satisfied with them. Electric mowers should not be made with this type of battery. It seems the engineers should have known this. With all the complaints regarding the batteries and repairs, Ryobi should issue a recall and replace the batteries. Dissatisfied and Disappointed.

Rated 5 out of 5 by from Good for smaller yards Excellent performance great price. Does well in dry conditions but if the grass is damp/wet it seems to bog down.

Rated 5 out of 5 by from Never going back to gas! This is my 2nd Ryobi zero turn electric rider and both of them have been fantastic. The first was a 42" 100AH that we used for 3 years and was flawless. We gave that one to our son for his large yard and bought the 54" 115AH model for our property. I mow about 3 acres and 80% of that is a field, not a lawn. Both of these mowers have just been great. Plenty of power, plenty of battery life, quieter, and none of the maintenance headaches I had with previous gas mowers. I'm never going back to gas. Never.

Rated 2 out of 5 by from Unreliable!! I bought this mower in Nov. of 2021 and was thrilled with its performance for the first season. Unlike many other reviews I surprisingly haven't had problems with battery degradation. April 2023 the infamous left arm issue that seems to plague so many customers started. Turns on fine, blades engage, but left arm only beeps when moved in either direction and will not move. This will be the 4th time it's been in the shop this year for various issues. The mower is unreliable. I may be able to mow 5 mins. or 15 mins. then it stops and beeps. It may or may not start after an extended wait time, then I have to push it back to the shed. I spent a total of $5300 for a pretty green Ryobi lawn chair! You would think since so many have had this same "left arm issue" there'd be a recall. With the number of times, it has been it the shop this year, for one thing or another, and the time it takes to receive parts (4 to 5 weeks) from start to return, Ryobi would consider the customer. The mower will have been in the shop as long or longer than I have had it to mow this season. I believe I purchased a "lemon".

Rated 4 out of 5 by from Awesome mower for the money. This thing is great! Love how it cuts my yard and saves so much time. And virtually no maintenance. I just wish the batteries lasted longer and recharged quicker.

Rated 1 out of 5 by from READ REVIEWS THOUROUGHLY BEFORE PURCHASING ZT540! I bought this mower in June of 2021 and was thrilled with its performance for the first season. Unlike many other reviews I surprisingly haven't had problems with battery degradation. I cut a total of about 5 acres per week but over three sessions. Mid season 2022 the infamous left arm issue that seems to plague so many customers started. Turns on fine, blades engage, but left arm only beeps when moved in either direction. What's more I purchased a 3 year extended warranty from home depot but lost access to the icloud account so I cannot access original receipt from online order. Home depot says "no help contact ryobi" while ryobi states not serviceable under warranty without receipt. That's a total of $5000 for a pretty green ryobi lawn chair! You would think since so many have had this same "left arm issue" there'd be a recall or at the very least accurate and readily available information on the replacement part. Curb Appeal & Maintenance has prided ourselves on zero emissions lawn care since 2018 and have only purchased Ryobi products. Trimmers, edgers, even chainsaws. I understand flawed product design and battery limits with current gen lithium but the complete disregard for customer relations while never taking into account customer loyalty was the last straw for me.
