The Sun Joe 24V-X2-17LM-CT is a powerful battery-powered, cordless electric lawn mower with dual 24-Volt lithium-ion batteries as its beating heart. This delivers an impressive amount of power via the 670-watt brushless electric motor.

The cutting deck of the Sun Joe 24V-X2-17LM-CT harvests a 17-inch wide swath of grass in a single pass. It is designed to divert the cut pieces of grass back to the 11-gallon grass collection bin. It also has an easy-to-read indicator that lets you know just how full it is. This is a great way to prevent harvested grass clippings from drying out into turf choking thatch.

It’s also worth noting that the cutting blade is made from hardened steel, which isn’t always the case with cordless electric lawnmowers in this niche. This helps preserve the sharp edge while reducing your need to sharpen or replace the cutting blade frequently.

The 17-inch cutting deck has 6 adjustable height settings. It lets you adjust the deck from as low as 1-inch high when the grass is growing vigorously. Then you can set it up as high as 3-inches for times when the weather has been dry for more than a week and you want to help preserve some of the lingering soil moisture.

The Sun Joe 24V-X2-17LM-CT only weighs 34-pounds and rolls easily across your lawn with special Easy Glide Wheels. It’s also light enough to be stored vertically.

Key Features

  • Dual 24-Volt lithium-ion batteries
  • 17-inch cutting deck

  • Only 34-pounds
  • 6 height settings


The dual 24-Volt lithium-ion batteries with 48 total volts of power in the Sun Joe 24V-X2-17LM-CT do an impressive job of driving the 670 Watt electric brushless motor. It’s also very easy to move across most level suburban lawns. Just bear in mind that it’s probably a little on the small side for larger yards of half an acre or more.

Ease Of Use

The Sun Joe 24V-X2-17LM-CT was designed to be very easy to use and store. The Easy Glide Wheels make it comfortable to push across your average suburban lawn. Its steel cutting blade lasts a long time without needing to be sharpened and replaced. The fact that it only weighs 34-pounds makes it easy to store on a shelf or in an upright position.

Though it’s important to note that this particular iteration of the Sun Joe 24V-X2-17LM-CT is the tool only and does not include the charger for the dual 24 Volt lithium-ion batteries.

Special Features

At first glance, the brushless electric motor might not seem like something special. Though it does translate into quieter operation, which is nice if your lawn is in a tightly-packed suburban area, or you have young children napping. It also produces far less heat, which translates into a longer overall lifespan for the electric motor. It also makes more efficient use of the power stored in the dual lithium-ion batteries, which makes for a slightly longer run time on a full charge.

The 11-gallon grass collection bin is another one of those features that might not jump off the screen as being “Special.” Though it certainly comes in handy. Not only does it prevent harvested grass clippings from turning into turf-choking thatch, but it also gives you green material to add to your compost pile or garden. The indicator lets you clearly see how much grass is in the bin. The 11-gallon size is perfect for one single dump for an average suburban lawn.

Cut Quality & Options

The 17-inch cutting deck on the Sun Joe 24V-X2-17LM-CT is just about right for clearing a wide swatch of grass while also helping to keep this cordless electric lawn mower lightweight for easy handling. The Easy Glide Wheels also make this cordless electric lawn mower nimble.

The cutting deck on the Sun Joe 24V-X2-17LM-CT can be adjusted through 6 distinct cutting heights to match the prevailing turf conditions. If sunny conditions and periodic light rain have your lawn growing like crazy, then you can set the cutting deck down as low as 1-inch to keep the grass tamed and neatly manicured. If the prevailing weather has been overly dry, you can dial the cutting deck height up as high as 3 inches to help shade the turf a little and preserve some soil moisture until the rains return.


The Sun Joe 24V-X2-17LM-CT requires very little maintenance for a cordless electric lawn mower. The steel cutting blade has a reputation for holding its edge for a long time. The brushless electric motor is also very energy efficient and will put less drain on the dual 24 Volt batteries. It also produces less heat than a similar electric motor with a brush-based drive system. This translates into less heat, which can be a factor for longer mowing sessions.

You will also appreciate that the lightweight of just 34-pounds means the Sun Joe 24V-X2-17LM-CT is very easy to store, and can even be kept in an upright position or on a heavy-duty garage storage shelf. Just be sure to follow the instructions in the owner’s manual regarding storage.

Safety Features

The Sun Joe 24V-X2-17LM-CT has the standard hand control safety features. The level indicator on the grass collection bin is also nice for preventing clogs in the chute or deck, which can be an issue for thick lawns or longer than average mowing sessions.


There are several different things that make the Sun Joe 24V-X2-17LM-CT more cost-efficient than a lot of other cordless electric lawn mowers. The brushless electric lawn mower is more energy-efficient, as well as producing less heat, which translates into a longer overall lifespan for the electric motor.

The bagger with its level indicator is also a cost-efficient benefit of this cordless electric lawn mower. Not only does it prevent inconvenient clogs, but it also keeps harvested grass clippings off your turf. Not only can this boost your compost pile or help you mulch your garden to prevent weeds, but you also save money by eliminating the need for seasonal aeration.
