Our Top Picks
The Ryobi Expand-It snow thrower attachment is the ideal solution for homeowners who already own a compatible Ryobi power head and need to clear light snow from decks, sidewalks, and short walkways without the expense or storage footprint of a full-sized machine. At a $149 price point, it offers excellent value for managing manageable accumulation, though it is not a replacement for a two-stage blower in heavy-snow regions.
The Ryobi snow thrower attachment is a $149 accessory that converts compatible Ryobi string trimmers into a lightweight snow blower. By detaching the lower shaft of the trimmer and connecting the snow thrower head, users can clear light snowfall from sidewalks, decks, and walkways. It features a 12-inch clearing width and a 6-inch clearing depth, making it a space-saving alternative to dedicated snow removal equipment for small residential areas.
Compatibility: Will It Work with Your Trimmer?
The most common mistake I see people make is buying an attachment that simply will not fit their existing equipment. The Ryobi Expand-It system is modular, but it requires an attachment-capable power head to function. If your current string trimmer has a coupler in the middle of the shaft that allows you to swap out the trimmer head for a leaf blower or a hedge trimmer, you are likely in the clear.
The Ryobi snow thrower attachment is designed exclusively for specific attachment-capable power heads within the Expand-It system. It is a Home Depot exclusive, meaning you will generally find it there or through authorized online resellers. This modular approach is part of the broader Ryobi lawn care philosophy, allowing you to use one motor for multiple seasons.
Before you head to the checkout, you must verify your power head model. The Ryobi snow thrower attachment compatibility list includes the following models:
- P20220
- RY42050
- RY40270
- RY40290
- RY40ST01
- RY40HPST01
If you are using an older 18V ONE+ system, check the motor's power rating. While the attachment will physically fit most 18V attachment-capable heads, the performance is significantly better when paired with the 40V HP Brushless motor. The higher voltage provides the necessary torque to spin the auger through denser patches of snow without the motor bogging down.
| Power Head Type | Performance Level | Best Use Case |
|---|---|---|
| 18V ONE+ | Moderate | Small wooden decks and porch steps |
| 40V HP Brushless | High | Long sidewalks and suburban walkways |
| Gas (2-Cycle/4-Cycle) | High/Consistent | Rural areas where battery charging isn't convenient |
To connect the unit, you simply loosen the wing nut on your trimmer shaft, press the locking button, and slide the lower shaft out. You then slide the snow thrower attachment in until the button clicks and tighten the wing nut. This tool-free transition is a major selling point for those of us who don't want to fumble with wrenches in sub-zero temperatures.
Real-World Performance: Decks, Walkways, and Wet Snow
When we look at the technical specs, the Ryobi Expand-It 12 in. Snow Thrower Attachment (Model RYSNW00) is designed with a 12-inch clearing width and a 6-inch clearing depth. In practical testing, these numbers are quite accurate for light, fluffy snow. When you are dealing with that "powder" that falls in mid-winter, this tool is a joy to use. It glides over flat surfaces and throws the snow about 10 to 15 feet away.
However, the real test of any Ryobi string trimmer snow blower attachment is how it handles the "heart attack" snow—that heavy, wet slush that accumulates at the end of a driveway after the city plow goes by. Because this unit uses a plastic auger and lacks a directional discharge chute, it does have limitations. In my experience, using Ryobi snow thrower attachment on decks and walkways is where it truly shines. The plastic auger is gentle on wood and composite decking, unlike metal-bladed shovels or heavy gas blowers that can leave unsightly scratches.
One issue I noticed during extended use is the vibration through the handle. Ryobi includes an offset handle with the attachment to help you maintain a comfortable posture, but the torque of the power head motor can still cause some hand fatigue after twenty minutes of clearing. Additionally, the Ryobi snow thrower attachment performance in wet snow can be frustrating because you cannot control where the snow lands. It throws the snow straight ahead, which means if you are clearing a long path, you might find yourself throwing the same snow twice if you aren't careful with your clearing pattern.
If the snow is deeper than the 6-inch clearing capacity, you will need to take it in layers. This is where the power head motor matters most. If you have the 40V HP Brushless version, you can skim the top three inches and then go back for the bottom three. If you try to shove a full 10 inches of snow into the 12-inch clearing width all at once, the motor will likely trigger its overload protection and shut down.
The $149 Verdict: Attachment vs. Dedicated Blower
So, is the Ryobi snow blower attachment worth $149? The answer depends entirely on your existing tool shed and your local weather patterns. This accessory is priced at $149.00 and is compatible with most brands of attachment-capable gas or cordless string trimmers, not just Ryobi. This versatility adds a lot of value for someone who might own a Toro or Craftsman power head.
When comparing the Ryobi snow thrower attachment vs dedicated 40V snow blower, the main advantage of the attachment is space-saving storage. A dedicated snow blower is a massive piece of equipment that takes up a significant footprint in your garage for nine months of the year. The Expand-It attachment can be hung on a wall hook, taking up no more room than a spare shovel.
Furthermore, the snow thrower attachment is backed by a 3-year limited manufacturer warranty and includes an offset handle to assist users in walking along a cleared path. This provides some peace of mind regarding the durability of the internal gears and the plastic auger.
Pros & Cons
- Pros: Significant cordless convenience; much faster than manual shoveling; lightweight and easy to maneuver on stairs; excellent for composite decks; small storage footprint.
- Cons: No chute to direct snow to the left or right; plastic auger can struggle with ice; requires a compatible power head; not suitable for large, multi-car driveways.
If you live in an area where you get occasional 2-to-4-inch dustings, the Ryobi Expand-It snow thrower is a fantastic investment. It turns a grueling hour of shoveling into a fifteen-minute walk. However, if you live in the "snow belt" and regularly deal with double-digit accumulation, you should skip the attachment and go straight for a dedicated 40V brushless snow blower with a metal auger and a discharge chute.
For most suburban homeowners with a single-car driveway and a small porch, this $149 add-on is a smart way to maximize the value of your Ryobi Expand-It system. It saves your back, saves your time, and—most importantly—saves your garage space.
FAQ
Is the Ryobi snow thrower attachment compatible with all power heads?
No, it is only compatible with attachment-capable power heads that feature a coupler for the Expand-It system. This includes specific Ryobi 18V, 40V, and gas models, as well as some other brands like Toro, Weed Eater, and Troy-Bilt that use the same universal connection system. It will not work with standard string trimmers that have a fixed, one-piece shaft.
How deep of snow can the Ryobi snow thrower attachment handle?
The attachment is officially rated for a 6-inch clearing depth. While it can handle slightly deeper snow if it is very light and fluffy, anything over 6 inches will require multiple passes—skimming the top layer first and then clearing the base. It is not designed for heavy drifts or snow piled up by street plows.
Does the Ryobi snow thrower attachment work on wet snow?
It can handle wet snow, but with significantly reduced efficiency. Heavy, wet snow tends to stick to the plastic auger and the internal housing, and the throw distance will drop from 15 feet to just a few feet. It also puts much more strain on the power head motor, which may cause the battery to drain faster or the motor to overheat.
Is the Ryobi Expand-It snow thrower worth it?
If you already own a compatible power head and only need to clear small areas like decks, patios, or short sidewalks, it is absolutely worth the $149 investment. It is much more efficient than manual shoveling and easier to store than a full-sized snow blower. However, it is not a primary tool for clearing large driveways in regions with heavy winters.
Can you use the snow thrower attachment on a 40V Ryobi power head?
Yes, the 40V Ryobi power head is actually the recommended power source for this attachment. The 40V system, especially the HP Brushless versions, provides the necessary power and torque to spin the auger effectively through snow. Using a 40V battery will result in better performance and longer runtimes compared to the 18V alternative.
