Knowing how to remove the string trimmer head and attach the brush cutter blade allows you to get to work on tougher items quickly. The removal of a trimmer head is also the same if you are installing a new trimmer head in place of a faulty one.
Things You Will Need
-
Put on leather gloves and safety glasses. Place your Troy-Bilt trimmer on a flat surface with the trimmer head pointing upward and allow it to cool completely if it was in use recently. Pull the boot from the spark plug.
-
Insert the straight end of the locking rod into the locking rod slot underneath the trimmer head. The locking rod is included in the purchase of a new Troy-Bilt trimmer and brush cutter. If you do not have the locking rod, insert an Allen wrench into the hole. Hold the locking rod's long end tightly to the shaft with one hand or hold an Allen wrench in place with one hand near the trimmer head.
-
Grasp the trimmer head with your other hand and turn it clockwise to unscrew it and lift it off the trimmer shaft.
-
Insert a flat-head screwdriver into the three screws in the cutting attachment shield, turn them counterclockwise and remove them. Set the cutting attachment and its shield aside for storage.
-
Install the brush cutter shield onto the trimmer with the three screws removed with a flat-head screwdriver. Place the brush cutter blade on the output shaft, followed by the blade retainer with the flat side down, and then the nut.
-
Insert the locking rod or an Allen wrench into the locking hole under the brush cutter blade and hold it in position. Turn the nut with a 13 mm wrench or an adjustable wrench until it is tight. Reconnect the spark plug.
