    • “using the self propelled mode”

    • “The self-propel feature can run without the blades running.”

    • “Self propel system switch sticks often and will not shut off.”

    • “The self-propel feature. I bought this feature more for my significant other, but the mower seems lighter weight than the Troy-bilt/Honda mower it replaced, so it actually feels like it pushes easier”

  • Several users say the battery life is great, letting them mow for a long time without having to recharge often. (5 reviews)

    • “Really long lasting battery”

    • “The charge in the battery is beyond impressive, I am tired of mowing before the charge runs out.”

    • “Runtime is very good”

    • “I still had between half and three quarters battery life indication after each use”

    • “It takes about two full batteries to mow my lawn when it is super long. If you keep up with your mowing should only take one charge.”

  • The mower's feature that automatically increases power when it hits heavy or thick grass is seen as a plus. (3 reviews)

    • “When ever it hits anything heavy, it increases powers automatically to power through it, then drops back to normal.”

    • “When the mower detects that the blade speed starts to slow down, it'll kick in to high blade speed.”

    • “Performs great when mowing thick brushy areas”

  • Several reviews appreciate the fact that the mower does not require oil or gas. This reduces maintenance efforts compared to gas-powered mowers. (3 reviews)

    • “Oh, did I mention, no oil, gas and POLOUTION including Noise.”

    • “I don't have to deal with the maintenance that an oil and gas mower needs.”

    • “No gas can, no oil level.”

  • The ability to adjust the speed of the self-propulsion lets users customize it to their preference and comfort. (3 reviews)

    • “The workaround is to play with the self propulsion speed (faster or slower... doesn't matter which. Just do your own preference). Keep adjusting it in very small increments until the mower stops randomly shutting off on you while you're using it.”

    • “Slow speed was like walking extremely slow. The next speed was like an extremely fast walk.”

    • “The speed control is a breeze to tweak to your desire”

  • The blade width is praised for covering more ground, reducing mowing time. (2 reviews)

    • “Also, the blade is not short, which helps to reduce moving time.”

    • “Cutting characteristics are generally good, but a little quirky in that the cutting width is just inside the inner wheels (actual blade width from tip to tip is 19.75")”

  • The ease of starting the mower with a push of a button is often mentioned, contrasting with the hassle of starting traditional gas mowers. (2 reviews)

    • “This mower instantly starts and does not stop until I want it too.”

    • “Charge the battery, check the blade, and mow !”

  • There is less pollution, and the mower is quieter. This is great for users who want to mow without making a lot of noise. (2 reviews)

    • “Oh, did I mention, no oil, gas and POLOUTION including Noise.”

    • “Wonderful, fume free, quiet mowing and at any time of day or night”

  • Users appreciate the quick charging feature of the battery, reducing downtime between uses. (1 review)

  • On high blade speeds, the mower exhibits decent vacuum power, which is useful for standing up grass blades for an even cut. (1 review)

4 reasons not to buy

  • The grass catcher fills up fast, which can be a hassle for people with big lawns or tall grass because you have to empty it often. (3 reviews)

    • “the bag fills sort of quickly, but probably it is because of my long grass in the yard”

    • “The mower will cut off four to five times to fill one bag with grass clippings.”

    • “mulching does tend to load up the deck and make for a more arduous cleanup task afterward as the deck will hold a large amount of pureed cuttings”

  • At lower blade speeds, the mower doesn't pull up the grass well, especially if you have a type of grass with wide blades. This can make the cut look uneven. (2 reviews)

    • “Horrible vacuum power in low blade speed”

    • “I have found out the front opening of this lawnmower is too low that pressed weeds under blade level, which left lots of weeds survived after cutting.”

  • Although this electric mower is pretty strong for its kind, it's not as powerful as gas mowers. This might make it less effective in very thick grass or on big lawns. (2 reviews)

    • “It definitely doesn't have the power of a gas mower but will definitely get the job done.”

    • “Manufactory probably needs to add teeth on blade with reaping hook to make cutting perfect flat. I have an old gas lawnmower it has teeth and reaping hook on blade it cuts much better than this.”

  • The self-propel feature takes about 5 seconds to disengage, which can make quick back-and-forth mowing less convenient. (2 reviews)

    • “The propel features takes a about 5 seconds to disengage so going back and fourth quickly is not easy to do unless you just push it yourself during those times.”

    • “One thing that is a bit weird about the self-propel, is the foot or two the mower must move AFTER the on/off propel switch is released”

Bottom Line

The KT 80-Volt Max is a robust electric mower with a powerful motor that tackles tough and thick grass with ease. It's self-propelled, making it user-friendly, and boasts long battery life for extended mowing sessions. The smart power boost in thick grass, hassle-free push-button start, and no need for oil or gas are a big plus. It's also quieter and less polluting. However, it may lag behind gas mowers in extreme conditions, and the self-propel can be slow to disengage. The grass catcher also fills quickly, so frequent emptying may be needed.
