Post driver
In viticulture, the stakes used for trellising are usually installed mechanically. The same tools used in viticulture are generally used in agriculture for fencing meadows or paddocks. Finally, some equipment, particularly portable equipment, can be used by private individuals to build a fence around a house, for example.
There are three main types of post driver used in viticulture, each adapted to specific needs:
Different types of post driver
Mast post drivers
This type of post driver is fitted with a vertical mast that guides the post during driving. It is generally mounted on machines such as tractors or mini-excavators. The mast ensures precise, straight driving, even in hard or uneven ground. This model is particularly suitable for large areas where even placement of posts is essential.Percussion post driver
Operated by a system of repeated impact, the percussion post driver is effective for driving stakes in dense or stony soils. The percussion mechanism generates successive shocks that drive the post into the ground quickly and effortlessly. This type is often fitted to heavier machines, such as tractors, to resist vibrations and ensure good stability.Thermal or pneumatic post drivers
These portable models are powered either by an internal combustion engine or by compressed air. They offer great mobility and are ideal for small farms or hard-to-reach areas. Lightweight and easy to use, they are also popular for work outside the vineyard, such as residential fencing. Their main feature is their autonomy, as they are not dependent on a heavy machine to operate.These three types of post driver allow winegrowers to adapt to different types of terrain and farms, offering a wide range of options in terms of mobility, power and precision.
Different mountings
- Tractor-mounted models: Post drivers can be installed on inter-row tractors, with different mounting options (rear frame, front frame or between the wheels). These machines enable you to work efficiently over large areas, driving the posts at regular intervals and with great precision.
- High-clearance tractors: For better manoeuvrability and an unobstructed view of the vineyard, some post drivers are mounted on the front of high-clearance tractors. This type of mounting is particularly suited to difficult terrain or sloping vineyards.
- Mini excavators and front-end loaders: These machines are extremely versatile, and can be used in confined spaces or for specific tasks. Post drivers mounted on mini-excavators are appreciated for their precision and ability to manoeuvre in inaccessible areas.
- Portable post drivers: Used mainly for smaller projects or hard-to-reach areas, these models are often thermal (motor-driven). Their portability means they can be used manually, which also makes them handy for work outside the vineyard, such as fencing around private properties.
Use outside viticulture
Although mainly used in viticulture, post drivers are also useful in general agriculture, particularly for fencing off meadows or livestock pens. What's more, portable models are becoming increasingly popular with private individuals for jobs such as demarcating a house.All in all, the post driver is an essential tool for winegrowing professionals, enabling them to streamline the process of installing trellis stakes while guaranteeing high precision and reduced physical effort.
