Key Differences Between Models
Power Source
The Sun Joe 15-Inch Corded Dethatcher relies on a 13-amp corded motor, meaning it needs a constant connection to an electrical outlet. This provides unlimited runtime but restricts your movement to the length of your power cord. In contrast, the Sun Joe 24V-CRLM15-CT is a cordless tool powered by a 24-volt battery system. It offers complete freedom from cords, allowing you to mow anywhere without tripping hazards. However, you must manage battery charge levels. The corded model suits large yards with easy outlet access, while the cordless unit is better for smaller, obstacle-heavy lawns.
Cutting Width
Both machines share an identical 15-inch cutting or dethatching width. This standard width means you will make the same number of passes over your lawn regardless of which tool you choose. For the Sun Joe 15-Inch Corded Dethatcher, this width covers thatch and debris efficiently. For the Sun Joe 24V-CRLM15-CT, it provides a consistent cut for grass clippings. Since the working width is identical, neither model offers a speed advantage in terms of coverage area per pass. Your choice will depend on other factors like power source and specific lawn care needs rather than width.
Drive Type
The Sun Joe 24V-CRLM15-CT is explicitly designed as a push reel mower. You must provide all the forward momentum, which offers a lightweight, manual experience but requires physical effort. The Sun Joe 15-Inch Corded Dethatcher also lacks an engine-driven self-propulsion system. It relies on four durable, easy-glide wheels to reduce fatigue, but you still push it. Since both units are manual push models, neither gives you an advantage in ease of movement. You will need to push both tools across your lawn, though the dethatcher’s wheels are specifically noted for smooth navigation.
Height Adjustment
The Sun Joe 24V-CRLM15-CT offers four manual height positions: 0.6, 1.0, 1.5, and 2.0 inches. This allows you to set a precise grass cutting height for your lawn. The Sun Joe 15-Inch Corded Dethatcher features a five-position depth control, but this adjusts the tines' penetration into the soil for dethatching, not a grass cutting height. Because they serve different functions, their adjustment mechanisms are not directly comparable. The mower provides traditional mowing height settings, while the dethatcher provides soil penetration depth settings. You cannot directly compare these as both are for different tasks.
Collection Bag Capacity
The Sun Joe 24V-CRLM15-CT includes an 11.9-gallon rear collection bag for grass clippings. This large capacity helps you mow longer stretches before stopping to empty it. The Sun Joe 15-Inch Corded Dethatcher also comes with a spacious, removable collection bag for thatch and debris. While the exact gallon capacity is not listed for the dethatcher, it is described as large and easy to remove. The mower’s specific 11.9-gallon volume is a clear spec advantage for mowing efficiency. For dethatching, the bag size is sufficient but less precisely defined in the data.
Which Sun Joe Model Fits Your Yard
You need to remove thatch and aerate soil
This model uses a 13-amp corded motor specifically designed for dethatching and scarifying. It effectively removes tough thatch and revitalizes grass.

You prefer lightweight equipment for easy handling
At 27.1 pounds, this corded dethatcher is lighter than the cordless mower option. It weighs less than the 31.8-pound Sun Joe 24V-CRLM15-CT. The unit features four durable, easy-glide wheels for effortless navigation. This design reduces user fatigue and improves overall comfort while you maneuver across your lawn during maintenance tasks.

Frequently asked questions
Can I use the Sun Joe 24V-CRLM15-CT to dethatch my lawn?
No, you cannot. The 24V-CRLM15-CT is a reel mower designed for cutting grass, not removing thatch. It lacks the specialized tines required for dethatching. For that task, you need the corded dethatcher, which uses rotating blades to scarify the soil and pull up debris.
Does the dethatcher come with a battery?
No, the dethatcher does not use a battery. It is a corded tool that plugs directly into a standard electrical outlet. This design provides continuous power without worrying about charge levels, but it limits your range to the length of your extension cord.
Is the 24V mower tool only?
Yes, the Sun Joe 24V-CRLM15-CT is sold as a tool-only unit. The listing indicates that the battery and charger are not included. You must already own compatible 24-volt IONMAX batteries to operate this mower. This makes it a good choice for existing Sun Joe users.

Do both machines have a 15-inch cutting width?
