The Stihl HSA 66 Cordless Hedge Trimmer 20″ is a quiet and lightweight cordless hedge trimmer with droplet shaped blades to guide branches in between the teeth and cut them efficiently.

This clever design also delivers in-built cut protection as the droplet shapes overlap the sharp cutting teeth to reduce the risk of them coming into contact with you. The screw-on tip protector also protects the blades when trimming close to the floor or walls.

The HSA 66 is powerful but easy to use – just push the battery in and you’re ready to go, without even needing to wear ear defenders.

The HSA 66 is part of the AP System PRO Cordless range of tools, with interchangeable batteries – it is not compatible with the AK batteries in the COMPACT AK Cordless System.

Functional design
The engine housing has smooth surfaces and round contours. This prevents the tool from getting caught on branches. The hedge trimmers are easy to clean.

Innovative cutting system
The blade shape has been optimised to catch branches and hold them against the blade during the cut and serves as an integrated blade guard.

Blade tip protector
The tip protector comes fitted as standard and makes cutting near the ground or along walls easier, whilst helping to protect the cutters from damage.

Protects the cutting blade for safe storage and transport.

1 review for Stihl HSA 66 Cordless Hedge Trimmer 20″

  1. Amy

    I bought this after I had bought the cordless strimmer as I was so impressed with the range. Pop the battery in and ready to go. Tackles all my hedges with ease, even lobbing some 2 inch branches. Quite heavy but then I am not used to such physical work. Fantastic peace of equipment. Gives me about 10 solid minutes on the AP 100 battery which is the lowest power so would get a lot more time upgrading to the higher one. You will not be disappointed.
