Thermal or pneumatic post driver
Thermal or pneumatic post drivers are powered either by an internal combustion engine or by compressed air. They offer great mobility and are ideal for small farms or difficult-to-access areas. Lightweight and easy to use, they are portable.
They are also popular for work outside the vineyard, such as installing residential fencing. Their main feature is their autonomy, since they do not depend on heavy machinery to operate them.

Component parts
The engine or compressor
Equipped with a two-stroke or 4-stroke internal combustion engine, depending on the model, the hammer is operated by a trigger.The pneumatic version, which is less widespread, relies on an air compressor to operate the hammer.
The hammer
The posts are driven by a bell which strikes the post like a jackhammer at a rate of around 1,500 to 1,700 blows/min.When driving metal posts, it is essential to use and place a martyr (or borrow) between the bell and the post in order to preserve the integrity of the iron post.
