TAS 103E 8.5" Sprinkler Head Trimmer Attachment. The TAS Trimmer 8" (Model 103) works great on Hunter G-90 and G-95 Rotary Heads, Rainbird series 900, Toro 650 through 780 series and Bear 870. It's designed to trim grass quickly and cleanly away from sprinkler heads, valve boxes, yardage markers, tee markers and bunkers (without liners). It is the top choice of Golf Course Superintendents throughout North America and Europe. The strong, one-piece steel design of the TAS Trimmer makes it superior to all other irrigation head trimmers.
