Comparison with HLA 56
The Stihl HLA 66 is the successor to the HLA 56. The main difference between the two models is the power of the motor. The HLA 66 has a brushless motor, which is more powerful and efficient than the brushed motor in the HLA 56. This means that the HLA 66 can cut through thicker branches and vegetation with more ease. The HLA 66 also has a longer cutting width (50 cm vs. 40 cm) and a longer reach (205 cm vs. 180 cm). However, the HLA 66 is also slightly heavier (3.8 kg vs. 3.4 kg).
Overall, the Stihl HLA 66 is a more powerful and versatile hedge trimmer than the HLA 56. However, it is also more expensive and heavier. If you need a hedge trimmer for heavy-duty trimming, the HLA 66 is a good option. If you are looking for a lighter and more affordable hedge trimmer, the HLA 56 is a good choice.
