Not all trimmer heads are interchangeable. The compatibility of trimmer heads depends on the specific make and model of the trimmer.
Different trimmer manufacturers use varying designs and attachment systems for their trimmer heads. It’s important to refer to the manufacturer’s guidelines or consult the trimmer’s user manual to determine which trimmer heads are compatible with your particular trimmer model.
Using an incompatible trimmer head can result in improper attachment, reduced performance, or even damage to the trimmer.
