2.11 Description of function
The Vento® II is a pneumatic granulate doser for applying seeds and granulated fertiliser in agriculture.
Precise dosing is achieved using a cellular rotor valve that is driven according to the speed of the vehicle. Automatic
dosing by means of a wheel sensor or GPS receiver is possible. The spreader has an agitator for spreading materi-
als with reduced free-flowing properties. The spreading material is applied by means of an airflow through 8 hoses.

3 Mounting and start-up
Warning!
Risk of injury due to inadequate attachment
If the spreader or hopper tip over, this can cause crushing or other injuries.
•Only mount the spreader on carrier vehicles that have a sufficient load carrying capability.
•Before start-up, make sure that the implement, spreading material hopper and hopper cover have
been correctly attached.
3.1 Implement holder
The Vento® II is supplied mounted on the universal
holder as standard. The mounting is specifically depen-
dent upon the carrier vehicle provided, and must be
adapted to its conditions.
Before operation, check the attachment of the spread-
er on the universal holder. The attachment must be se-
cured with the safety bolts (1). If replacing them, use
M10 bolts with a strength class of at least 8.8, with self-
locking nuts.
Optionally, installation is possible using U-brackets
(2) on a square tube with dimensions 80×80 mm to
120×120 mm.
3.2 Install the control panel
Install the universal holder supplied in the package in the working range of the driver.
The installation is specifically dependent upon the carrier vehicle provided, and must be adapted to its conditions.
Advice
Select the installation position so that the accessibility of other controls is not adversely affected.
1. Secure the universal holder to the vehicle using
point (1) and (2).
