T35 Tap Advance Trimmer Head, part # 537 38 81-01
Exclusively designed by Husqvarna, the T35 Professional Tap Advance trimmer head features an easy to reload spool that comes off with the cap, eliminating the need to turn the trimmer upside down to reload the line. The spool has a split design which reduces tangling and line welding, and has arrows to show the correct directional winding of the line to eliminate guesswork. The spool has two key slots to lock the trimmer line in and keep it from unwrapping while putting the cap back on the trimmer head. The T35 holds .065", .080", .095", or .105" trimmer line and has a capacity of 28 feet of .095" gauge line, one of the best in the industry and comes pre-wound with .095" Titanium Force™ trimmer line.
