Rated 5 out of 5 by from Game changer I bought this as a back up mower, but it is so much faster it cuts my mowing time as well as the grass!

Rated 3 out of 5 by from Long term durability issues starting to concern me After 50 hours of use starting my forth season. I’ve already stated all the things I like about this mower in my two other reviews. See tapeguytech, so now I will update on how the mower has held up. One of the blade drive motors kept shutting off and had to be replaced. If this had not been under warranty I would have been less that happy. The mechanic noted he had seen a few of these and wheel motors go bad. If electric motors are going bad with less than 50 hours of use, I am worried about this mowers long-term cost of ownership. This silver metal pin that holds the black plastic grass shoot on, keeps sliding out. I carry a small hammer and tap it back in after each use. There does not seem to be anyway to correct the issue. I got too close to a bush and a limb broke the flimsy plastic charging port cover off, It's now held on with duct tape. The mower still randomly faults out for no reason. A few times it has shut off while going at full speed, coming to a bone jarring stop. Sometimes there is a delay from when you press the accelerator and the mower moving. Sometimes after fully charging the battery gauge will show, 1/2, 3/4 or full. The seat sensor is much to sensitive, turn your body, sneeze or cough and the mower may shut off. Would I purchase this mower again? It depends on what improvement have been made and what else is on the market. With that said I still do not regret this purchase. Even with its short comings there is a lot to like about this mower.

Rated 1 out of 5 by from Wanted to like it, but not ready for primetime. Bought this in June of 2018, from day one had nothing but problems. 1st e-clip wasn’t installed on the steering wheel and the vertical steering shaft movement broke the steering wheel. 2nd, starting getting low voltage errors errors and randomly the blade would shut off. 3rd, steering sensor went our and the mower wouldn’t move, had to tow it back to the garage which was the final straw. Ended up returning to dealer for the gas model. I really like the idea of this mower and when it did run it was great, but it is way too unreliable at this point.

Rated 5 out of 5 by from Love this machine Bought this mower this month after researching other electric rider and gas riders. We also have Greenworks blower and Ego push mower as well as Ego weed eater - all outstanding and powerful products. (Full disclosure, I can't wait for Infiniti qx80 to come out in all electric model!). I have never owned a riding mower but have been paying someone to mow our 4.5 acre backyard. I am very non mechanical but wanted to expand my horizons and try a rider. Well, I am thrilled with this mower. It is very easy to operate, cuts effectively, rides smooth, and just a lot of fun. I want to get it out of the garage every day and take it for a spin and cut some grass!! This weekend I bought a pull behind cart and it pulls it effortlessly (I got the idea from a reviewer). Next I am going to buy a pull behind spreader to spread rye seed this Fall. I should add that I asked the dealer to attach a little hitch that comes on other gas Cadet riders. The electric is plenty powerful enough to pull it. It runs a strong 2 to 2 1/2 hours on full bore mowing g. The field has some longer grass and tough weeds but it handled them with no issue. Overall, one of my great purchases last couple years and I highly recommend this 42" RZTS zero electric. ( Oh, it also has cruise control and a tight ZERO turn with a steering wheel!)

Rated 5 out of 5 by from Exceeded all expectations We purchased this one year ago when we decided to tackle our 3/4 acre lot on our own going forward and stop paying a service. We looked at a lot of mowers and after running into an article about electric lawn mowers in Mother Earth News I started doing some digging. After quite a bit of research we decided on this one and have not looked back. There are so many things to like about it there is not room to list them all. It is so quiet! Even when the blades are on it is tolerable without any kind of ear protection. There is almost no maintenance. Grease the wheels and sharpen the blades and you are done. I love getting the service reminders from my local dealer and looking at the list of things they want to do and laughing because none of them apply to this mower. It can easily mow our lot twice on one charge although now that I have the wagon I have been using it for all kinds of projects around the place so I usually charge it one night per week and it is set for another seven days worth of hard labor. The only drawback is the aluminum blades. My wife was too close to the drainage ditch and hit a rock about the size of a brick and it twisted it into a pretzel. Other than that it is complaint free and I cannot recommend it highly enough. You need this if you at all considering buying a riding mower!

Rated 5 out of 5 by from Best mower I have used this mower for three seasons now and it is the best mower I have ever owned. It's very quiet: I forget my hearing protector sometimes and it really isn't necessary. It cuts very evenly. The batteries gave me about two and a half hours of mowing time per charge the first season. That dropped to about 90 minutes the second season and about 45 minutes the third season. I was disappointed with the drop off but I did use the mower far more than it was designed for. They recommend it for about 3/4 of an acre and I was mowing probably three times that, so perhaps the batteries would last longer under those conditions. I will order new batteries for next season.

Rated 3 out of 5 by from Tough mower BUT... This is my third season using the zero, first let me say I love the low maintenance, and this thing (when working) can go with the best of them. I actually used mine to clear brush (4ft) very slowly with multiple passes. My issue has been maintenance when something goes wrong. My something was mice, in my first year mice found its way in the mower and nested on the wires. I live in NE so mice are the norm. I have since mouse proofed the shed. The first repair was fine, cleaning and wire replacement, however the battery would not maintain a charge, it would charge all week and nothing. So I took it back in, this is a pain because my closest dealer is two states away! This time they said the batteries were bad and changed them. So I get it home and yes the batteries charge but they die in about 30-40 mins, I have a little less than an acre and when this thing was brand new I could cut my lawn 2 times on one charge, now I can't even cut half my lawn. So I now have to drive back to Mass/Rhode to have it looked at again.

Rated 4 out of 5 by from 20 cents to mow my yard! Well as my first summer with an electric mower comes to a close, here is my update. I'm starting to love this mower. Especially using it with wagon in tow, as a utility unit. Hop on it zip over there, five minutes later zip to the other side of the yard. Zero issues with mowing my grass, has only shut off one time in thick clover. Just turn on the turbo boost and take your time and it will cut through some thick grass. It's taking slightly less than 2 KWH of electricity to recharge after mowing 3/4 acres. 2 KWH comes to 20 cent for me, now that's low cost. As I drive an 100% electric car, I know electricity leaves gasoline way behind. An internal combustion engine (ICE), is less than 30% efficient. 70% of the energy in a gallon of gas is wasted as heat. Whereas an electric motor is over 90%, that's why I can cut my gas for $0.20
