MOUNTING
Tractor connection (mounted version)
Increased risk of injury
When connecting, there is high risk of injury, so never stay between tractor and
machine. Check categories of connected devices of machine and tractor,
categories have to be the same.
➢On the lower arms of the linkage, fit the appropriate balls of the lower arm and secure
them with fuses.
➢Set the lower arms to the same height.
Ensure, that fuses of lower arm click. If they don’t click, the machine could be
released from the lower arms.
➢Connect machine to the tractor, ensure, that fuses of lower arms are clicked.
➢Adjust the lower arms to keep the machine slightly free to left and right.

Tractor connection (trailed version)
While connecting, there is high risk of injury, so never stay between tractor and
machine. Check categories of connected devices of machine and tractor,
categories have to be the same.
➢Lock-off the pin on tractor`s lower linkage.
➢Connect the seeder to the tractor.
➢Lock the pin on tractor`s lower linkage.
Fan drive
Fan on the Venga seeding machine is driven by a pulley, which is through V-belt driven by
tractors power shaft or by hydraulics directly from the tractor.
➢Connect PTO shaft –if the machine is equipped with mechanic drive –on power take-
off of the tractor.
PTO shaft - connect only when tractor engine is off.
➢Power take-off speed set to 540 RPM. At this speed, fan should reach optimal speed.
By increasing or decreasing power take-off speed, you will change fan sped.
➢If the machine is equipped with hydraulic fan drive, connect it to hydraulic circuit; oil
overflow has to be connected directly to the tank- free fall. If tractor isn’t equipped

with Load sensing system, it is recommended to connect fan drive to preferred
circuit. Then, set fan speed by control valve from 3500 to 4500 RPM.
Connections
Electrical system
➢Connect the machine light connector.
➢Connect the connector for additional electrical equipments.
Hydraulic system
➢Connect hydraulic hoses to the tractor.
→chapter Hydraulic system
Hydraulic system
Before connection check all hydraulic hoses and their fixed connection in
couplers. Connect hydraulic only when it is not under pressure. Hydraulic
system under pressure can cause machine movements.
Don’t mix oil types. Machine use with different tractors can cause mixing two
types of oils. This mix can damage tractors devices. Use only permitted type of
oil.
Fan speed can`t be over 5000 RPM. Fan can be damaged by higher speed.
Connectors of hydraulic hoses or color coded. To one hydraulic circuit always connect only
hoses with the same color code. Hydraulic circuits are equipped with ball valve, which are
necessary to open.
Hoses color coding:
- White –control of lifting an axle
- Blue –disc markers
- Yellow –folding / unfolding
- Red –hydraulic fan drive

Hydraulic fan drive
Hydraulic fan drive should connect to tractors pre-fitted control valve. This
minimize fan speed fluctuation when lifting and putting down the machine or
other hydraulic loan.
The oil flow leads to a three-way valve for flow regulation and is regulates the hydraulic
motor speed. Fan speed have to be controlled by tractor’s terminal.

No-pressure return
No-pressure return reduces the risk of hydromotor’s damage. It is important to choose the
right position of connecting the hydromotor to hydraulic system, because:
- returning oil have to flow through the hydraulic filter,
- returning oil can’t flow through control valves, because pressure in return will be
too high.
