The Cat SR118 Snow Blower is a heavy-duty attachment built for skid steer loaders, compact track loaders, and compact wheel loaders. As a mechanic who’s worked on a lot of Cat gear, I can tell you this model is designed for serious snow removal. It uses a two-stage system: an auger to break up the snow and an impeller to throw it clear, giving it the strength to handle everything from light powder to packed, icy drifts.
Cat SR118 Dimensions
| A. Intake Width | 64 in (1614 mm) |
| B. Overall Width | 74 in (1877 mm) |
| C. Cutting Height | 34 in (867 mm) |
| D. Overall Height | 73 in (1843 mm) |
| E. Overall Length | 37 in (951 mm) |
The unit’s intake width is about 64 inches, and it can throw snow as far as 40 feet when the conditions are right. It’s a solid, well-built attachment weighing around 430 kilograms, so you’ll want to make sure your machine can handle that load comfortably.
Cat SR118 Specs
| Maximum Throw | 40 ft (12 m) |
| Snow Blower Weight | 1054 lb (478 kg) |
| Auger Diameter | 18 in (457 mm) |
| Impeller Fan Diameter | 25 in (635 mm) |
| Impeller Fan Width | 8.7 in (222 mm) |
| Chute Rotation | 270° |
The SR118 runs best on machines with standard hydraulic flow roughly 20 – 23 gal/min (76 – 87 L/min) at about 2800 – 3300 psi (19300 – 22750 kPa) of pressure. You’ll need a 14-pin electrical connection for the hydraulic chute controls. The chute itself can rotate up to 270 degrees, which means you can direct snow exactly where you want it without repositioning the machine. That, combined with the hydraulic deflector, makes it easy to work around obstacles or keep snow away from buildings and vehicles.
Cat SR118 Required Hydraulics
| Required CAT Hydraulics | Standard Flow |
| Optimal Hydraulic Flow | 20 – 23 gal/min (76 – 87 L/min) |
| Optimal Hydraulic Pressure | 2800 – 3300 psi (19300 – 22750 kPa) |
One thing I like about this blower is how service-friendly it is. It comes with a bolt-on reversible cutting edge, adjustable skid shoes, and a reversible auger and impeller, all of which make maintenance and wear part replacement straightforward. The coupler height can also be adjusted to fit different machine types, so it’s versatile across a range of Cat models. The offset chute design improves visibility from the cab, which makes operation safer and less tiring over long shifts.

For contractors, municipalities, or anyone dealing with heavy winter workloads, the SR118 is a dependable choice. It’s powerful, reliable, and built to last, but it does require proper hydraulic capacity and regular maintenance to keep it running smoothly. If your loader or track machine meets the flow requirements, this attachment will handle snow clearing on streets, parking lots, or driveways with ease – the kind of performance you’d expect from a Caterpillar-built tool.
