4 Usage
4.1 Coupling
Before coupling the machine, ensure that it has been correctly immobilised.
1. Check the machine and tractor couplings for wear and cleanliness.
2. Move the tractor up to the machine.
3. Couple the machine.
a) Machines with coupling on the lifting arms :

Couple the machine

Lock the catch hooks

Tension the stabilisers to prevent lateral movement

Ensure that the level of the linkage is set so that the machine frame is in a horizontal position

Connect the hydraulic brake connector
b) Machines with hitch ring :

Adjust the height of the drawbar so that the machine can be coupled.

Couple the machine.

Insert the bolt and lock it.

Connect the hydraulic brake connector
c) Machines with ball coupling :

Lower the drawbar or cap onto the ball and raise the machine slightly.

Position the clamping frame.

Check and adjust the size of the gap between the clamping frame and the cap.
4. Fold in the support legs and lock them in place with the pin provided.
4.2 Hydraulic connection
The operation of the seed drill requires :
- 1 double-acting hydraulic valve for folding and unfolding the machine's wings.
- 1 double-acting hydraulic valve to raise and lower the seeding units in the field.
- 1 double hydraulic valve for the use of markers (optional).
- 1 single-acting to power the hydraulic turbine.
- 1 free return (male in 3⁄4) to the tractor's hydraulic oil tank for turbine oil return.
When using a tractor with a variable flow pump and integrated regulators (closed circuit), the tractor's regulator must
be used to adjust the fan speed.
The oil flow rate required for a turbine speed of approximately 4,500 rpm is 45 l/min.

Clean the hydraulic connections before connecting.

Connect the hydraulic hoses that supply the folding system to a double-acting valve.

Connect the hydraulic hoses required to supply the markers to a double-acting control valve.

Connect the free return of the turbine (photo).

Connect the turbine supply to a single-acting valve.
4.3 Electrical connection
1. Plug in the road signal electrical socket.
2. Connect the power supply plug of the regulator (photo)
3. Connect the cigarette lighter socket to the power supply of the touch pad.
!
Never operate the valve controlling the turbine without having correctly connected the free return,
otherwise the turbine motor may be damaged.
