3 Inch vs 4 Inch Chipper Specs
Cutting capacity
The SuperHandy model handles branches up to 3 inches in diameter. This fits most residential pruning tasks and small yard waste. The MechMaxx model accepts material up to 4 inches wide. This extra inch allows you to process thicker limbs without cutting them down first. If you manage larger trees or have frequent thick brush, the MechMaxx capacity is more practical. For light garden cleanup, the SuperHandy size is sufficient. The difference matters when you want to avoid pre-cutting smaller branches.
Horsepower
Both machines list 7 HP for their engines. The SuperHandy uses a 4-stroke single cylinder OHV gas engine. The MechMaxx also uses a 4-stroke single cylinder OHV gas engine with a DUCAR 212cc displacement. Since the horsepower rating is identical, neither product has a clear power advantage on paper. You can expect similar torque for standard chipping tasks. The actual performance may vary based on engine tuning, but the spec sheet shows equal power output for both units.
Reduction ratio
The reduction ratio shows how much the machine shrinks waste volume. The SuperHandy achieves a 15:1 ratio when using the top hopper for smaller material. The MechMaxx achieves a 20:1 ratio. A higher ratio means the chips are smaller and more compact. This helps you fit more debris into your truck or compost bin. The MechMaxx provides better volume reduction. If you haul chips away often, the MechMaxx efficiency saves space. The SuperHandy ratio is standard for its class.
Blade system
The MechMaxx features a double-edge blade design with two blades and one anvil. The blades are made from CR alloy steel for corrosion and wear resistance. The SuperHandy does not specify its blade count or material in the provided data. The MechMaxx design aims for sharper cuts and less maintenance. Double-edge blades can be flipped when dull. Without specific data on the SuperHandy blades, the MechMaxx offers a more detailed and potentially durable cutting system based on the specs.
Dimensions
Size affects storage and transport. The SuperHandy is 25.7 inches wide, 29.5 inches long, and 40.6 inches high. It is compact and fits in smaller garages. The MechMaxx is 31 inches wide, 76 inches long, and 43 inches high. It is significantly longer and wider. The MechMaxx includes a tow bar and wheels for movement. The SuperHandy requires a separate tow bar kit. If you have limited storage space, the SuperHandy is easier to park. The MechMaxx needs more room.
Which Chipper Fits Your Needs
Small yard owners with limited storage
The SuperHandy model measures 25.7 inches wide and 40.6 inches high. This compact footprint fits tight garages or small sheds. Its 3-inch capacity handles typical pruning branches. You avoid the bulk of larger units while still getting a 7 HP engine for reliable residential performance.
Users needing to process thicker branches
The MechMaxx chipper accepts wood up to 4 inches in diameter. This extra capacity lets you process larger limbs without cutting them down. The 20:1 reduction ratio breaks material into finer chips. You gain efficiency for larger yard waste or light forestry tasks that exceed 3-inch limits.
Operators valuing transport and durability
This unit includes a tow bar and two 14-inch wheels for easy movement. The CR alloy steel blades offer high strength and wear resistance. Kevlar belts reduce maintenance frequency. You benefit from a design built for frequent use and easier relocation across large properties or job sites.

Frequently asked questions
Does a 4 inch chipper need more power than a 3 inch model?
Both listed models use 7 HP gas engines. The MechMaxx 4-inch unit pairs this with a 212cc engine displacement. This suggests similar power output for their respective capacities. You do not necessarily need a higher horsepower rating just to handle the extra inch of diameter.
How much larger is a 4 inch wood chipper physically?
The 4-inch MechMaxx model is significantly bigger. It measures 76 inches in length and 31 inches wide. The 3-inch SuperHandy model is much more compact at 29.5 inches long and 25.7 inches wide. The larger unit requires more storage space and is designed for towing.
Can I tow a 3 inch wood chipper?
The SuperHandy 3-inch model does not list a tow bar in its attributes. It is designed as a stationary or manually moved unit. The MechMaxx 4-inch model explicitly includes a tow bar feature. You should choose the 4-inch option if you need to transport the chipper with a vehicle.
Is a 3 inch capacity enough for typical yard work?
Yes, for most homeowners. The SuperHandy 3-inch chipper handles moderate brush and standard pruning branches. Its 3-inch maximum capacity covers the majority of residential yard waste. You only need the 4-inch capacity if you regularly process larger branches or thicker hardwood limbs.
Do I need a gas engine for wood chipping?
Both recommended models use gas-powered engines. The SuperHandy offers 7 HP, while the MechMaxx also provides 7 HP with a 212cc engine. Gas power provides the mobility and torque needed for dense wood. Electric models are not listed here, so gas is the standard for these heavy-duty tasks.
Which chipper is better for a small garage?
The SuperHandy 3-inch model fits better in tight spaces. Its dimensions are 25.7 inches wide and 40.6 inches high. The MechMaxx 4-inch model is 76 inches long and 43 inches high. The larger unit will not fit in a standard small garage due to its length and tow bar.
What is the difference between a 3 inch and 4 inch chipper?
The primary difference is the maximum branch diameter they accept. The SuperHandy handles up to 3 inches, while the MechMaxx accepts up to 4 inches. Both use 7 HP engines. The 4-inch model is also larger and includes a tow bar for transport, unlike the compact 3-inch unit.
