When you compare a 201 vs 151 wood chipper, you are looking at two specific models from GARDENBEAUT that share the same core engine specs. Both units feature a 7 HP, 212cc gas engine and handle up to 3 inches of wood. The main difference lies in their reduction ratios. One model offers a 20:1 ratio for finer mulch, while the other provides a 15:1 ratio. This choice affects how finely the debris is shredded and how much volume you reduce.

Which one should you choose?
Choose GARDENBEAUT S1 7 HP 3-Inch Wood Chipper if
- You want a higher reduction ratio to create finer mulch from your branches.
- You prefer a machine with a specified dual-bearing design and larger cutting rotor for stability.
- You need a lighter unit that fits standard wheelbarrows or small trailers.
Choose GARDENBEAUT S3 7HP Gas Wood Chipper if

20:1 vs 15:1 Chipper Specs
Reduction Ratio
The GARDENBEAUT S1 offers a 20:1 reduction ratio, while the S3 provides a 15:1 ratio. A higher reduction number means the machine chops material into smaller, finer pieces. With the S1, you get more mulch from the same amount of brush. This is useful for creating fine garden soil amendments. The S3 still reduces volume significantly, turning branches into manageable chips. However, the S1’s 20:1 ratio gives you a finer output for composting or bedding. If your goal is fine mulch, the S1 has the edge.
Cutting System
The S1 features a large 15.6-inch cutting rotor equipped with two blades and six hammers. This setup is designed for efficient shredding and consistent speeds. The S3 data does not specify the internal rotor size or the exact number of blades and hammers. Both machines handle 3-inch wood, but the S1’s specific configuration suggests a more robust processing mechanism. The combination of blades and hammers in the S1 helps transform debris into mulch quickly. Without detailed specs for the S3’s cutting head, the S1’s described hardware offers a clearer advantage for heavy-duty shredding.
Discharge Chute
Both the GARDENBEAUT S1 and S3 feature a vertical extended discharge chute. Each includes an adjustable discharge guide with an angled range of 90° to 145°. This allows you to direct debris accurately for easier cleanup. Since both models share this identical feature, neither has a functional advantage here. You get the same level of control over where the chips land. This consistency means you do not lose convenience by choosing one model over the other based on discharge capabilities. Both deliver precise debris discharge for efficient yard maintenance.
Weight and Portability
The S1 weighs 119 pounds and includes 10-inch PU wheels for all-terrain use. It also has a dual bearing design for stability. The S3 data lists a weight of 7.48 ounces, which appears to be a data error for a gas chipper. The S3 is described as compact and lighter than other steel chippers. Assuming the S3 is indeed lighter, it may be easier to move. However, the S1’s 119-pound build with sturdy PU wheels suggests better stability during operation. If you need a lighter unit, the S3 claims an advantage, but the S1 offers proven stability features.
Engine and Power
Both the S1 and S3 are powered by a 7 HP, 212cc horizontal 4-stroke single-cylinder OHV gas engine. They both use 87+ unleaded gasoline with no ethanol recommended. The S3 has a 0.7-gallon maximum fuel capacity. The S1 data does not list fuel tank size. Since the engine specs are identical, performance should be similar for standard tasks. The S1 includes a low oil alert sensor for engine protection. The S3 does not mention this sensor in the provided data. For power, it is a tie, but the S1 offers an added protective feature.
Choose the right chipper for your yard
You want finer mulch and faster processing
The GARDENBEAUT S1 delivers a 20:1 reduction ratio, chopping branches into smaller, finer pieces than the S3. Its 15.6-inch rotor and dual bearing design provide stability during high-volume use. You get more consistent mulch for enriching garden soil, with a vertical discharge chute that allows adjustable angles from 90 to 145 degrees for precise placement.
You need a lighter unit for transport
The GARDENBEAUT S3 is designed to be compact and lighter than standard steel chippers. While both share the same 7 HP engine, the S3 is marketed as the mini option with strong power. Its smaller footprint and reduced weight make it easier to move around your property or store in a smaller shed when not in use.
You prefer a more stable, heavier base
The S1 weighs 119 pounds, providing a solid, stable platform for heavy-duty chipping tasks. Its dual bearing design adds extra stability compared to the lighter S3. This weight helps keep the machine steady while processing thick branches, reducing vibration and ensuring safer operation during extended periods of yard cleanup and debris management.
