“Comes with everything you need to make the conversion. Heavy duty, solid construction, appears to be very durable. Time will tell how long it will last but it appears well built and easy to install and use. Came shipped to my door. I highly recommend this product.” - Bondo

Way More Power

Double Duty. Specifically engineered to cut more grass per rotation, the Aero-Flex® system has twice the blades as traditional trimmer heads, hitting and cutting vegetation more frequently on each revolution so you can get more done in less time, with less effort.

“I was given this kit as a gift and I cannot say enough about it. The blades are very durable and the instal was very easy. I have noticed my gas powered trimmer uses less fuel than it did before and cuts nicely at the lowest speed. I will never go back to a string weed eater system again.” - James
