HSA 66 Cordless Hedge Trimmer
Handy cordless hedge trimmer with 50 cm / 20" blade length
Overview
The HSA 66 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.
- Working time with recommended AP 100 battery: Up to 72 minutes

STIHL Smart Connector
STIHL connected is a smart fleet management system that enables professional users to digitally manage machine fleets and work assignments.
This is managed by the STIHL Smart Connector - a sensor with a diameter of just under 5cm, which is mounted on the tool. It can be mounted on petrol, electric or battery-powered tools where it records and saves the operating hours while the motor is running and transmits this information via Bluetooth® 4.2 to the STIHL connected App (the smart connector can be mounted on non-STIHL tools too). The Smart Connector offers entirely new functions and services, as a basis for device management both in your home garden using the STIHL connected App, and for managing your machine fleet using the STIHL connected Portal.
Here’s a few reasons why STIHL connected can help manage your fleet of tools:
- The Digital Fleet Management keeps a record of all tools and their service record
- You get prompts when a tool needs servicing, so you never forget to change the plug, filter or just carry out maintenance
- You can see how many hours a tool has done, so you can plan which tools to use, replace or buy more of
- At the end of the day, you can open the app and see which tools are next to you - so you can tell if something is missing
- Book a service with your nearest STIHL Approved Dealer and give them access to see what work will be needed in advance.
STIHL Connected is an intuitive way to manage your machine fleet and workload intelligently and efficiently. Visit: STIHL connected FAQs to find out more.
