Connection to tractor hydraulic system

The attachment can be connected to any tractor hydraulic system available on the market.

Connection to tractors with constant-flow hydraulic system or load-sensing system

The quick release coupling 8040 is connected to a control unit port of the tractor with adjustable oil flow.

This control unit provides oil supply for the attachment and is adjusted to a constant volume flow of Qmax = 50 l/min.

The system screw 6034 is turned out up to the stop so that the input pressure balance 7063 is operative.

The quick release coupling 8041 is in general connected to the pressureless return line T of the tractor.

If a pressureless return line is not allowed in continuous operation (e.g. because lubrication of the tractor gearbox is not guaranteed), a double-acting control unit can be used for supplying oil to the attachment.

In this case, the quick release coupling 8040 is connected to port A (feed) and quick release coupling 8041 to port B (return) of the corresponding tractor control valve.

Adjust the volume flow to Qmax = 50 l/min; please refer also to the tractor's Operating Manual, e.g. "Continuous operation of hydraulic motors".

The quick release coupling 8042 (LS, working hydraulics signal) is not used with this connection option.

If the tractor is not provided with a flow-adjustable control unit, the volume flow must not exceed 50 l/min.

Connection to tractors with constant-pressure hydraulic system

The quick release coupling 8040 is connected to a control unit port of the tractor with adjustable oil flow.

This control unit provides oil supply for the attachment and is adjusted to an oil flow of approx. Qmax = 50 l/min.

The system screw 6034 is turned in up to the stop so that the input pressure balance 7063 is blocked.

The tractor's hydraulic pump is shut down when the system pressure has been reached.

The quick release coupling 8041 is connected to port T (pressureless return line) of the tractor.

The quick release coupling 8042 (LS, working hydraulics signal) is not used with this connection option.

2/3 The quick release coupling 8040 is connected directly to the pump via the Power Beyond port P. The quick release coupling 8041 is connected to port T (pressureless return line) of the tractor.

The quick release coupling 8042 (LS, working hydraulics signal) is connected to the tractor's "LS signal" port when using this connection option.

The system screw 6034 is turned in up to the stop so that the input pressure balance 7063 is blocked.

The tractor's hydraulic pump regulates as a function of the attachment's load signal.

Test points / Characteristics

When no function is active on the attachment, the attachment must not load the tractor hydraulically (The tractor engine speed must not be reduced).

The allowed temperature of the tractor's hydraulic system must not be exceeded; see also the Operator's Manual of the tractor.

Connection to tractors with load-sensing system without a Power Beyond port

The quick release coupling 8040 is connected to a control unit port of the tractor with adjustable oil flow.

This control unit provides oil supply for the attachment and is adjusted to a constant volume flow of Qmax = 50 l/min.

The system screw 6034 is turned out up to the stop so that the input pressure balance 7063 is operative.

The quick release coupling 8041 is in general connected to the pressureless return line T of the tractor.

Quadrant 2100

Overall hydraulic system

3/3 As soon as the QUADRANT is mechanically driven, the baling pressure hydraulics pump 2036 pumps a constant oil flow into the baling chamber hydraulic cylinders 3034.

The oil pressure in the baling chamber hydraulic cylinders 3034 is controlled by the baling pressure build-up solenoid coil Y050.

To achieve this, the baling pressure build-up solenoid coil Y050 is actuated by the electronic unit using pulse-width modulation (PWM).

When the baling pressure build-up solenoid coil Y050 is not energized, the maximum oil pressure is reached in the baling pressure hydraulic system. This pressure is set to 150 bar at the factory.

The baling pressure sensor B056 transmits a signal to the electronic unit which corresponds to the oil pressure. This pressure is displayed on the terminal.

The baling pressure measuring point 9011 can be used for measuring the pressure and for bleeding the baling pressure hydraulic system.

Working hydraulics

When the solenoid coils Y048, Y145, Y150 and Y151 in the working hydraulics basic block are actuated, they transmit a load signal to the input pressure balance 7063 and to the tractor's LS signal port 8042. This is required for building up the oil pressure in the working hydraulics.

(Exception: tractors with constant-pressure hydraulic systems); see also section "Connection to tractor hydraulic system".

When the solenoid coils Y142, Y147 and Y148 in the additional valve block are actuated, the solenoid coil Y150 or Y151 is actuated at the same time.

The additional valve block is supplied with volume flow by the actuated solenoid coil Y150 or Y151.

Function of input pressure balance 7063 in constantflow operation

The spring space of input pressure balance 7063 is relieved towards return line T when no working hydraulics function is activated.

When volume flow is flowing, the pressure balance is opened against the spring.

The volume flow flows from 8040 P to 8041 T with a low circulation pressure.

When a function is activated which requires pressure build-up in the working hydraulics, a load signal is transmitted into the spring space of input pressure balance 7063. This load signal and the spring force control the pressure balance.

Pick-up hydraulic system

When the pick-up is lowered, the volume flow flows out of the pick-up hydraulic cylinders 3031 across the pressure relief valve (80 bar) 7006.

These 80 bar hold the pick-up in this working position, accumulator 5009 provides spring-type suspension.

The working hydraulics (pick-up) measuring point 9001 can be used for measuring the pressure and for venting of the pick-up hydraulic system.

Baling pressure hydraulic system

The baling pressure hydraulics pump 2036 provides a constant oil flow when the machine is driven. The oil pressure in the baling chamber hydraulic cylinders 3034 is controlled by baling pressure relief valve 6022 and indicated by baling pressure gauge 9012.

Ejecting the bale

The bale ejector hydraulic cylinder 3007 is controlled by the bale ejector control valve 6032. The bale ejector shut-off valve 6035 must be actuated.

The double-acting control unit on the tractor is actuated so that volume flow flows through quick-release coupling 8043. When the bale ejector control valve 6032 is actuated, the baling pressure hydraulic cylinder 3080 is also retracted. This sets the baling pressure relief valve 6022 to 0 bar.

5009 7006 7032

Description of function: Raise pickup (Extend cylinder)

Oil from the tractor control unit flows to port (X) through the non-return valve (7032) with an upstream restrictor via port (Y) to the pick-up cylinders.

The pressure relief valve (7006) is without effect since oil pressure is applied on both sides. This fills the accumulator (5009) almost completely with oil, making it ineffective.

Lower pick-up (Retract cylinder)

Oil from the pick-up cylinders flows to port (Y) through the pressure relief valve (7006) via port (X) to the tractor control unit into the sump.

The non-return valve (7032) blocks the direct oil flow from port (Y) to port (X).

The pressure relief valve (7006) maintains the pressure in the pick-up cylinders at the set value (approx. 80 bar for PFS).

Due to this, the accumulator is only partly filled with oil and thus acts as floatation spring for the pick-up.

Note:

06/07

Proper function of the pick-up floatation requires that the tractor control unit is set to blocking position as soon as the pick-up sensing wheels touch the ground.
