The Homelite UT-20046 is a 25-cc string trimmer that uses a universal head. The head assembly should be replaced when the strings get cut or frayed. You can purchase replacement head assemblies online or at stores that sell home and garden equipment. Replacing the head only takes a few minutes and can make trimming the grass at the edges of your lawn a quicker operation.
