Scientifically Engineered for Superior Design and Value

Aero-Flex Engineers have developed a new way to efficiently cut vegetation without overstressing the equipment being used while providing a significantly more efficient trimming process. The high-tech MACH 4^® System is scientifically consistent with the basic laws of Engineering with some of the formulas involved ??? below.

Aerodynamically streamlined – More power!

Low air drag coefficient – tear drop (low drag) efficiency Also reduces friction and drag through grass Requires less than ½ power

Higher mass /higher kinetic energy/lowerdrag

Major power improvement – Does more work even at lower speeds.

Higher mass – more cutters Higher kinetic energy in line blades Concentrated delivery into vegetation Improved erognomics Lower noise (200% drop) Very powerful line blades Symmetrically balanced - very smooth and comfortable (low vibration)

Higher line blade mass creates higher line blade power

Strong blade-like structure – Yet with flexible hinge!

• Delivers more torque
• Cuts at lower RPM

Higher centrifugal force Higher line blade mass creates higher centrifugal force combined with a better blade-like structure creates a stronger cutting mechanism.          MACH 4® line blades can achieve the same or greater centrifugal force as conventional lines but at much lower speeds.
Higher Centrifugal Force Better Structure

Low stress design at key locations reduces breakage

At outlet Large surface areas absorb high forces Large outlet radius                            Stress levels greatly reduced Impact release hinge – cushion impacts – a flexible living hinge Larger areas absorb force thus reducing operating stresses (extends life)

Low Stress Design

High kinetic energy concentration slices through heavier vegetation with ease

Greater number of line blades Higher line blade mass creates greater line blade power Sharper leading edge radius concentrates the higher forces, breaks down vegetation fibers easier Kinetic energy density is 8x greater Slices heavy vegetation conventional line cannot begin to cut           Materials – high grade nylon copolymers and new compounds without need of moisture                                                                                                 Manufacturing processes – conventional molding systems for high production volumes
	Kinetic energy density (KED) is 8x greater - Slices through heavy vegetation conventional line cannot begin to cut
