The HTA 66 is a lightweight, but powerful cordless pole pruner, which is ideal for cutting high branches in those hard-to reach areas, thanks to the 240cm length.

The HTA 66 has a 1/4" PM3 STIHL saw chain, which has been manufactured to the highest standards in our own factory in Switzerland to deliver high quality and efficient cutting at all times.

It's easy to use and can be used either right or left-handed, and low vibration so it's comfortable when working. It's quiet too, so there's no need to wear ear defenders. For greater comfort, consider adding the RTS Super Harness

It's just the tool you need to help you keep shrubs and trees in order.

Check out our blog to find out the four signs of a dull chain. This can be easily done for you at your nearest STIHL dealer, or you can do it yourself using a filing kit, or our 2-in-1 EasyFile that makes chain sharpening a breeze.
