The new Oregon PivoTrim Pro trimmer head is the newest innovation in string trimmer head design. It is designed to dramatically increase trimmer line life and reduce line welds and breaks, while offering outstanding performance. Standard trimmer heads force trimmer lines to bend and weaken at the eyelet, but the Oregon PivoTrim Pro’s patented pivoting attachment point deflects impacts and dissipates heat from the lines by allowing them to swing freely from 4 stainless bushings. The Oregon PivoTrim Pro is universal for all gas and propane trimmers and yields unmatched performance on rough terrain like chain link fence, rock borders and heavy vegetation. Its innovative design also offers quick line loading, and it conveniently uses standard .095" or .105" trimmer line.
