The Speed-Feed® trimmer head is the fastest loading bump-to-advance style head on the market. In fact, it can be reloaded without disassembly in 30 seconds or less - there is no need to press in stiff tabs or unlock covers just to re-load line.
The Speed-Feed® is perfectly balanced for vibration-free operation, and its smooth cover design glides while trimming. It comes pre-loaded with .095" diameter Silentwist™ trimmer line. The Speed-Feed® 400 is universal and includes adapters for use on both straight shaft and curved shaft models (non-bulk pack only). The Speed-Feed® 500 trimmer head is for units above 25cc.
