Sun Joe iON100V-21LM Features and Specifications
Sun Joe iON100V-21LM may be purchased as a bare tool (tool only) or as a lawn mower kit, consisting of:
- Sun Joe iON100V-21LM lawn mower,
- Sun Joe iON100V-5AMP 100V 5.0Ah lithium-ion battery,
- Sun Joe iON100V-RCH Rapid Charger for 100 volts ION100V Series batteries.
Also, Sun Joe offers iON100V-2.5AMP lithium-ion battery, which can be also used with Sun Joe iON100V-21LM lawn mower, but also with other Sun Joe tools designed for these batteries.
Sun Joe iON100V-21LM is designed as a 3-in-1 walk-behind lawn mower, with three 'basic' lawn mower functions including mulching, side-discharge, rear-discharge into 13.2 gallons (50 liters) collector bag.
Sun Joe iON100V-21LM is powered by a strong and energy-efficient 1000W brushless motor, offering output power just like some corded units.
Although the unit features '21LM' as part of its label and many sites claim that the cutting width is 21-inch, this is a lawn mower with 20-inch (~51 cm) wide cutting width.
Sun Joe iON100V-21LM weighs 61.7 pounds (28 kg) without the battery and is a rather maneuverable unit, at least across the level terrain.
To help users mow their lawns more easily, Sun Joe iON100V-21LM is designed as a self-propelled lawn mower.
Note: Sun Joe iON100V-21LM is actually very easy to, assemble, use and maintain a cordless lawn mower, just be sure to read the manual thoroughly when the unit arrives.
Self-propelled feature can be engaged when the blade is not spinning and vice-versa, the blade may be in use, while the self-propelled feature is not in use - this allows the user to extend the battery lifetime by not using self-propelled feature while mowing, but also it allows the user to transport the lawn mower to shorter distances using the self-propelled feature with the blade turned off.
The self-propelled feature is turned On/Off using an additional lever near the handle, while the speed is set using a rotating dial, also near the handle.
Sun Joe iON100V-21LM comes with adjustable cutting height with 7 possible positions, including 1.2 inches, 1.57 inches, 1.97 inches, 2.36 inches, 2.76 inches, 3.35 inches, and 3.75 inches (3 - 9.5 cm), which is more than enough for most users.
When the unit is not in use, the handle may be folded forward, helping with the storage space.
Thanks to the powerful electric motor, sharp and balanced blade, Sun Joe iON100V-21LM provides clean and uniform cuts, leaving the yard or lawn cleanly mowed.
Blade's no-load speed is 2800 rpm (~47 rotations per second), which is a good result for a cordless lawn mower with a 20-inch blade.
Note: Sun Joe iON100V-21LM comes with typical safety features commonly found at walk-behind lawn mowers. But, the education of users is the most important factor for safe lowing - hence, when the unit arrives, pay special attention to Safety Instructions!
