The STIHL HS 72 and HS 74 are gas-powered hedge trimmers – for your information, HS is the gas-powered hedge trimmer range designation, HSE is electric, and HL are extended-length hedge trimmers (which are gas).
The HS 72 and 74 are basically identical machines – they have the same identical 23.9 cc engine and everything else – the only difference is that the HS 74 has a rear handle twist lock. This is a lever for rotating the rear handle – an additional feature.
The HS 72 and 74 were made in both Germany and the USA, but information on the trimmer is hard to find. They were produced between 1992 – 1996, so it’s not a long run.

The HS 72 shares a manual with the HS 74. There is another version with the HS 74, HS 76, and the BG 72 (a gas-powered leaf blower).
We emailed STIHL to see if we could get the HS 72 / 74 manual, and they sent it through. You can download it here.
The model pictured here is made in Germany (seen on the STIHL tag), but we’ve seen other HS 72s with “Made in the USA” labels as well.

There are plenty of HS 72 and 74 parts on eBay at the time of writing.
This includes petrol hoses, engine covers, new blades, mufflers, air filter covers, blade brake assemblies, carbs, cutter guards, flywheels, and more.
Parts supply doesn’t appear to be an issue, and they are also reasonably priced.
Stihl hedge trimmer blades can be replaced or sharpened.
User ‘cscltd’ on ArboristSite shared (edited for clarity):
The HS 72, 74, 76 are rated pro models. Based on FS 76 Japanese trimmer engine.
The HS 45 is a home owner model.
If the HS 72 Hedge Trimmer is anything like Stihl Chainsaws in the quality of build and performance, this will be an excellent product.
Stihl HS 72 / 74
While it’s hard to find any user reviews on the HS 72 and 74, they appear to run well in the few videos of it on YouTube.
Also, those who have run one appear happy with their performance. There’s no doubt it will get light work done, but as it’s only a 24 cc hedge trimmer, it’s not for huge jobs.
The HS 76 is a more powerful version of the 72/74, but more commonly found models are the HS 75, 80, and 85. Personally, we use the DEWALT battery-powered hedge trimmer – it’s also good for light work.
