4 reasons not to buy

  • The self-propelled feature of the Redback 21" Lawn Mower has been described as too fast with no variable speed control, making it difficult to mow at different paces. Additionally, the self-propel activation is overly sensitive, making it hard to control. (4 reviews)

    • “It would be nice if there was a variable drive since it is pretty quick and not every mowing situation calls for rabbit speed. Its pretty much on or off.”

    • “The activation lever is super sensitive. As soon as you touch it, the mower takes off... It runs smoothly while you're cutting in a straight line, but it's hard to control it around those corners or other awkward areas. The self-propulsion is convenient, of course, but the drive speed is pretty fast, so he felt he nearly had to run to keep up with it, and there is no way to adjust the speed.”

    • “The best feature is that it has a motor and can pull itself along. This greatly reduces mowing effort (and battery life too probably). ... I like the pace it pulls at as well, but that is not adjustable as far as I know.”

    • “Cannot control self propel speed , if you push too fast it bogs the mower, so you are stuck on slow mowing either way.”

  • The mower was found to be as heavy as a gas-powered one, which could be a disadvantage for some users. The size and weight of the battery contribute to this issue. (3 reviews)

    • “however some may find the 120v battery a bit heavy.”

    • “definitely don't get this unless you lift weights, it's HEAVY”

    • “As heavy as gas powered.”

  • While the mower has a dual grip safety shutoff, one user noted difficulty in stopping the mower quickly due to the design of the self-propel lever which requires full hand extension. (1 review)

    • “The handle for the self propelled portion is a little hard to grab when you are not looking at it because even with size 13 shoes and large hands, it is difficult to stretch one hand to reach.”

  • A review mentioned that cables just hang from the handlebars and could get caught on something, requiring the use of zip ties to secure them. Also, the handle does not fold quickly for storage, demanding the removal of bolts and mounts. (1 review)

    • “The cables were pre connected and you can see in the picture, they just hang there. I ended up taking some zip ties and tying them to the handle bars so they are less likely to get caught on something. The handle does not fold quickly. You must remove 2 bolts and two quick screw mounts.”

Bottom Line

The Redback 21" Lawn Mower is a battery-powered mower ideal for people who need a reliable and easy-to-use tool. It boasts extended battery life, lower noise levels, and quick assembly. The mower cuts effectively, handles various lawn conditions, and has a convenient one-handed deck height adjustment. It offers mulching, rapid battery charging, and a foldable handle for storage. Downsides include a fast and sensitive self-propelled feature, heavy weight, complicated handle folding, and loosely hanging cables.
