Tractor-mounted anti-frost machine F252

These machines have a 2-speed gear box. On the lower speed, less horsepower is needed. Of course, the protected area will be smaller. To have most weight as close to the tractor as possible, the fan is mounted vertically and two gas bottles are put in front of the fan. There are 3 different models: • The F252 has two lower exits. It’s capacity (6 to 8 ha) is not as big as the capacity of the F501 (8 to 10 ha) • The F252S has 1 low and 1 high exit. This machine is smaller than the F252 and can be used in rows of 2m wide.. • The F152 has only one exit below and therefore less capacity then the F252 (2 to 4 ha). It’s ideal for smaller, narrow plots. How does it work? The Frostbuster is a trailed or 3-point mounted machine. The powerful fan is driven by the PTO of the tractor. In the air inlet of the fan, there is a gas burner that heats the air up to 80° Celsius. At the back of the machine are the containers for the gas bottles. The heated air is blown between the trees through 2 outlets (1 at the left and 1 at the right). Because the air flow is so powerful, we cover a distance up to 40 to 50 meters at each side of the machine. Therefore, it’s only necessary to drive through the rows every 60 to 90 meters. We will calculate for you the ideal circuit which is different for almost every orchard. However, it is very important to pass at the same spot within 10 minutes. The total surface that can be protected depends on the shape and the dimensions of the plot.
