I have an Echo HC151 hedge trimmer with 21.3cc engine. It is very reasonable priced. I have it for over 2 years. It works. Question is , a lot of time when I trim anything with stems half inch or over diameter, the branch can get caught and jam the trimmer. The engine can still run when I push harder but the clutch slip and go nowhere. Am I asking too much on a small trimmer like this? Any suggestion on a good strong commercial hedge trimmer? Weight don't matter. I don't want the long pole type, only the regular single or double sided 30 or 40".
