    Standard features

    • Sturdy branch hook

      After pruning, loose clippings can be easily removed from the tree with the branch hook.

    • STIHL EC-motor

      The STIHL brushless electric motor (EC) is very energy efficient and practically maintenance free. Thanks to its outstanding efficiency, the battery power is directly translated into impressive performance. During operation, the electronically controlled EC motor permanently monitors the load and adjusts the engine accordingly.

    • Ergonomic control handle

      The HTA 66 has a locking lever (orange front), ERGO lever (black) and main trigger lever (orange below). The locking lever is self-resetting and prevents unintentional switching on of the device. When the ERGO lever and shift lever are pressed, you can work continuously with ease.

    • Perfectly balanced

      The battery in the shaft of the HTA enables balance during use and allows for fatigue-free work.

    • Side chain tensioner

      The chain tensioner is located on the side to prevent contact with the chain when adjustments are made.

    • Tool-less oil cap

      Patented cap for the oil tank, the tank can be quickly opened and closed without effort and tools.
