Grass bag features a capacity of 11 gallons (~40 liters) and can be easily attached and detached from the rest of the lawn mower. Also, the grass bag features a small grass indicator window - as long as the air flow keeps the grass indicator window open, the grass bag is not full. When the flap closes during the mowing, the grass bag is full and must be emptied.

Without the batteries, Sun Joe 24V-X2-17LM weighs 30.2 pounds (13.7 kg), and with a pair of 24V 4.0 Ah batteries, it weighs 33.8 pounds (15.3 kg).

As one can see, Sun Joe 24V-X2-17LM is a rather lightweight unit - cordless design, lightweight construction, and easy-glide wheels ensure that the unit is rather maneuverable and able to reach and mow all corners and edges of the yard, garden or lawn.

Note: Like all similar units, Sun Joe 24V-X2-17LM is unable to cut the grass all the way into the corners, but the amount of uncut grass is minimal.

The unit is equipped with 670 watts high-efficient brushless motor, which is being powered by a pair of 24V 4.0 Ah batteries - the unit cannot operate using only one battery.

Note: battery's maximum voltage is 24 volts and the nominal voltage is 21.6 volts - these are 6-cells lithium-ion batteries that are able to store ~86.4 Wh of energy, each (~173 Wh total). batteries

The maximum runtime is ~65 minutes, although this highly depends on the grass type and height, battery condition, blade sharpness, and similar.

Sun Joe 24V-X2-17LM cordless lawn mower kit comes with a pair of 24V 4.0 Ah batteries and a dual-port, quick battery charger that is able to recharge these batteries in under two hours (1h 50 minutes).

Battery charger monitors the condition of the batteries, and if the batteries are too hot or too cold, batteries will not be charged - it is highly recommended to cool down the batteries after use and not to recharge them right away.

batteries and charger

Note: Sun Joe manufactures several batteries compatible with Sun Joe 24V-X2-17LM and they range from 2.0 to 5.0 Ah. Never, but really never use the batteries of the different capacity for powering of Sun Joe 24V-X2-17LM or any similar unit - such use may damage the battery, to say the least.

For example, 24V 5.0 Ah batteries are recharged in 2h and 20 minutes and they feature maximum runtime of 1h and 15 minutes (10 minutes longer than 4.0 Ah batteries). Again, this is the 'maximum' expected runtime and in the real-life, one gets less than that - 24V 4.0 Ah batteries may power Sun Joe 24V-X2-17LM for 40-45 minutes on flat, even terrain, with grass of common height and thickness (found at most lawns, gardens, and yards).


Sun Joe 24V-X2-17LM cutting width is 17 inches (~43 cm) and is well suited for a 670W cordless unit - cutting width is wide enough for the user to mow a relatively large area quickly, but still narrow enough for the blade to provide clean cuts.

The blade can be easily removed for sharpening or replaced with a new one - again, just be sure to follow maintenance procedures found in the Owner's Manual.

Note: when the motor is turned off, the blade continues to spin for few more seconds. After turning the motor off, wait for the blade to completely stop before continuing with any other task like emptying the grass catcher bag, cleaning the cutting deck, changing the batteries, etc. Better safe than sorry... After all, the no-load speed of the blade is ~3700 rpm (~62 rotations per second).

height adjustment

Cutting height is adjustable using a single lever with 6 height positions, ranging from 1 to 3 inches (25 - 75 mm), which is more than enough for most users.

Sun Joe 24V-X2-17LM cordless lawn mower comes with a 2-year limited warranty, which is a very good warranty for the unit in this class.

sun joe 24v x2 17lm mLong Story Short: Sun Joe 24V-X2-17LM Cordless Lawn Mower Kit is a well-balanced unit that is able to do its job. It is a powerful unit for a cordless lawn mower and can help the user keeping small to medium size lawn in good condition and looking neat.

However, don't expect any cordless unit of this size and power to compete with large corded and especially not with a gas lawn mowers.

But, the Sun Joe 24V-X2-17LM is also a very quiet unit, which can be of great importance in many situations.
