Which one should you choose?

Choose MechMaxx 6-Inch 15 HP Gas Wood Chipper if

  • You need to process thicker branches up to 6 inches in diameter.
  • You prefer a lighter machine that is easier to tow and maneuver.
  • You want a 360° rotary discharge chute for precise debris placement.

Choose MechMaxx 5-Inch 15 HP Gas Chipper Shredder if

  • You primarily handle smaller branches and twigs under 5 inches.
  • You require integrated tail lights and warning signs for road transport.
  • You do not mind the extra weight for a slightly more robust frame.

Verdict: Choose the 6-inch model if you need to handle larger diameter wood and want a lighter, more maneuverable unit. The 5-inch model is suitable for smaller branches and includes essential road safety features like tail lights. Both offer the same engine power and efficiency for general yard waste management.

Chipper Specs Compared Side By Side

Cutting capacity

Edge: MechMaxx 6-Inch 15 HP Gas Wood Chipper

The MechMaxx 6-Inch 15 HP Gas Wood Chipper handles branches up to 6 inches in diameter. This larger intake opening allows you to process thicker limbs without pre-cutting them into smaller sections. In contrast, the MechMaxx 5-Inch 15 HP Gas Chipper Shredder is limited to 5-inch diameter wood. If you frequently deal with heavy brush or large tree limbs, the extra inch of capacity on the first model saves you time and effort. The difference is significant for clearing larger yard waste efficiently.

Engine displacement

Edge: Tie

Both machines use a 420cc engine displacement. This specification indicates the total volume of all the cylinders in the engine. A 420cc displacement generally provides ample power for residential and light commercial wood chipping tasks. Since both units share this exact engine size, you can expect similar torque and power delivery from the motor. There is no advantage in raw engine size for either model, as they are mechanically identical in this regard.

Horsepower rating

Edge: Tie

Each chipper is rated at 15 horsepower. Horsepower measures the rate at which work is done, and 15 hp is a robust output for a gas-powered chipper. This power level ensures the blades can maintain speed under load, even when feeding dense wood. Because both the 6-inch and 5-inch models list the same 15 hp figure, neither has a power advantage. You get the same pulling force and cutting speed from the engine in either unit.

Reduction ratio

Edge: Tie

Both chippers feature a 20:1 reduction ratio. This ratio describes how many times the input material is reduced in size by the output. A 20:1 ratio means that a 5-inch branch will be reduced to chips approximately 0.25 inches in size. This consistency helps in creating uniform mulch or sawdust for landscaping and soil enrichment. Since both models share this specification, the fineness of the resulting debris will be comparable between the two machines.

Blade material

Edge: MechMaxx 6-Inch 15 HP Gas Wood Chipper

The blade construction differs slightly between the two models. The 6-inch chipper uses A8 alloy steel, specifically 5Cr8MoVSi, for its double-edge blades. This material offers high strength and good wear resistance. The 5-inch chipper uses CR alloy steel for its blades. While both materials are designed for corrosion resistance and durability, the specific alloy composition varies. The 6-inch model lists a more complex alloy, which may offer distinct wear characteristics, though both are built for heavy use.

Safety features

Edge: MechMaxx 5-Inch 15 HP Gas Chipper Shredder

Safety equipment varies between the two units. Both include an emergency stop button on the upper feeding drum and a press bar on the lower side for quick shutdown. However, the 5-inch chipper adds triangle warning signs and tail lights. These features are crucial if you plan to tow the machine on public roads or work near traffic. The 6-inch model does not list these lighting features in its specifications. For road transport safety, the 5-inch model has a clear advantage.

Physical dimensions

Edge: MechMaxx 6-Inch 15 HP Gas Wood Chipper

The physical footprint and weight differ significantly. The 6-inch chipper is 109 inches long, 47.9 inches wide, and weighs 441 pounds. The 5-inch chipper is shorter at 99 inches long, narrower at 41 inches wide, but heavier at 547 pounds. The 6-inch model is lighter and more compact in width, making it easier to maneuver in tight spaces. The 5-inch model is shorter overall but heavier, which might affect stability or transport needs differently. You should choose based on your storage and towing capabilities.

Which Chipper Fits Your Needs

You need to process thick limbs

Our pick: MechMaxx 6-Inch 15 HP Gas Wood Chipper

The MechMaxx 6-Inch model handles wood up to 6 inches in diameter. This larger cutting capacity allows you to feed thicker branches directly into the hopper without pre-cutting them. The ZONSEN 420cc engine provides the power needed for these larger pieces, making it the better choice for heavy yard cleanup tasks.

You want safety features for towing

Our pick: MechMaxx 5-Inch 15 HP Gas Chipper Shredder

The MechMaxx 5-Inch unit includes tail lights and triangle warning signs. These features are essential if you plan to tow the chipper on public roads. The 420cc engine offers sufficient power for standard yard waste, while the added lighting ensures you remain visible and compliant with traffic safety regulations during transport.

You prefer a compact footprint

Our pick: MechMaxx 5-Inch 15 HP Gas Chipper Shredder

The 5-Inch model measures 41 inches wide and 99 inches long. This smaller physical profile makes it easier to maneuver in tight garden spaces or store in a compact shed. While it handles slightly smaller branches, its narrower design offers practical advantages for users with limited storage or workspace constraints.
