3.2 Linkage and Traction Mode
Vehicle brake system:
The trailer can be equipped with various types of brake system (acc. to the relevant
national regulations).
a) Compressed air brake (two-line air brake system)
b) Hydraulically operated brake system
The tractor brake system must match the relevant trailer brake system.
Before starting up, make sure that all road safety and operating safety regulations
have been complied with and that the brake system and lighting function correctly.
Where compressed air brake systems are used, check that the brake power control is
correctly positioned. (see note 19.2)
Hitch the vehicle to the tractor in the prescribed manner. Be particularly careful during
hitching and unhitching!
Ensure that the tractor hitch has been approved to take the hitch eye fitted to the trailer.
If a ball hitch 80 is being used take particular care that the crop guard to ball clearan-
ce is adequate when driving on stacks.
To attain greater freedom of movement on the tractor-side “Scharmüller ball head
hitch”, use the shorter crop guard 1 (Scharmüller order no. 02481316).
Damaged or bent hitching equipment is a threat to safety and should not be used
again.
Before every start-up or drive make sure that there is no-one in the danger zone. Watch
out in particular for children.
When reversing make sure you have a good all-round view. You may need an additio-
nal person to guide you.
After hitching or unhitching is completed, adjust the support stand as required and
secure.
Before loading check that the back panel and/or inspection door is/are closed. Fold
up the inspection ladder.
Do not put down loaded vehicles onto supports.
Before unhitching make sure the support stand is in a stable position. Secure vehicle
against rolling (parking brake, chocks).

OPERATING INSTRUCTIONS
Page 8 Mega-Trailer
Independent braking must be prevented (lock pedals) on all runs with trailers.
Do not go between tractor and trailer while the engine is running.
Observe permitted axle loads, tongue loads and laden weights, in particular the maximum
tongue load which the trailer hitch can take on.
It is forbidden to go within the chute rotation range of the hydraulically swivelled back panel.
When maintenance and repair work is being carried out with the back panel open, the latter
must be secured by closing the stop cock.
Keep an eye on the reactions of your tractor on the road when the load is unevenly distributed
due to loading and auxiliary parts.
Always adapt your driving speed to the prevailing local conditions. When driving up and
down steep hills as well as across hills avoid sudden cornering.
Ensure adequate steering and braking performance.
Single and tandem axle vehicles with tongue load are in danger of tipping over if they have
been unevenly loaded, especially during hitching or in uncoupled condition. Ensure sufficient
tongue load!
Please take care during driving and unloading on the stack that the vehicle is kept stable.
(danger of tipping over)
When driving over stacks with soft sides keep to the middle as the danger of tipping over is
particularly high. Take care to stay at a safe distance from anyone in the vicinity!
Lock the steering axle when driving across slopes and over stacks.
This is recommended for driving on public roads.
If the steering axle is not locked, cornering at high speeds is not permitted.

3.3 P.T.O. Operation (only with discharge unit)
Observe the operating instructions of the drive shaft manufacturer.
Only use the drive shafts specified by the manufacturer.
Mount and dismount the drive shaft only when the engine has been switched off and the
ignition key removed.
Only use the drive shaft with the proper safety guards and in good condition as well as
making sure the protective tubes are secured against twisting.
Ensure sufficient tube overlapping on the drive shaft.
When cornering and with overrunning brake, keep to the permitted bending range and
ensure adequate drive shaft leeway.
Before switching on the P.T.O. shaft make sure that the selected speed and sense of rotation
of the tractor P.T.O. corresponds to the permitted speed and sense of rotation of the machine.
Before every drive shaft start-up check that the locking mechanisms have locked into place
properly.
Never switch on the drive shaft with the engine switched off.
If drive shafts with overload or free wheel clutch are used, these types of clutch must be
mounted on the trailer side.
After the P.T.O. shaft has been switched off, the unit driven by it can run on.
Stay out of the danger zone until all the equipment has come to a standstill.

3.4 Wheels, Tyres, Brakes
To ensure operation safety, wheels, tyres and brakes are subject to special checks.
Retighten wheel nuts after a short period of use and after every 50 hours of operation (see note 11.3)
Check air pressure regularly (see note 5)
Check tyres as well as wheels and brakes regularly for wear and tear. Check brake lines regularly for leaks and
good general condition.
Connect brake system properly before start-up.
Adjustments and repairs to the brake system are only to be carried out by authorized brake service centres or
qualified personnel.
Fitting tyres and wheels requires specialist knowledge and equipment.
If you wish to use a different tyre size, please consult the vehicle manufacturer first.
3.5 Hydraulics
Check the hydraulic lines and hose as well as fittings and parts for damage and leaks regularly. Hydraulic hoses
should be replaced every 6 years. Only use spare parts that meet the manufacturer’s requirements.
Ensure that the hydraulic hoses never bend or rub.
When connecting to tractor, make sure the hydraulic system is depressurised both on the tractor and machine side
and make sure the hydraulic connections do not get mixed up (accident risk due to reversed functions). Keep the
hydraulic couplings clean.
Attention: The hydraulic system is under high pressure. Before carrying out any
maintenance or repair work, always depressurise the system.
Liquids (hydraulic oil) escaping under pressure can penetrate the skin causing serious injuries
and infections.
Never try to block leaks with your fingers.
If injuries occur, consult a doctor or medical services immediately.

6. Hydraulic System
Every hydraulic function is directly connected with and controlled from the tractor.
The tractor requires a double- or single-acting control valve with free return (red = supply; blue = return) for
the floor conveyor drive.
A free return direct to the hydraulic oil tank is preferable as it involves less tailback pressure.
A double-acting control valve on the tractor is required for each of the following functions: Tailgate, steering
axle, hydr.upper front panel or hydr. stand. The control valve requires a floating position for the steering
axle.
As a special feature, an electro-hydraulic remote control is available for controlling. The hydraulic block is
constructed in modular design so that optional equipment can be fitted at a later date by simply extending
the hydraulic block. The flow regulator for the neutral circuit, the pressure relief valve and the floor conveyor
valve are to be found in the pump inlet plate. Speed adjustment for consumers other than the floor conveyor
is regulated from the adjusting screw on the intermediate plate.
6.1 Regulating the floor conveyor
All Mega-Trailers (with or without discharge unit) are equipped
with hydraulic floor conveyor drive. The floor conveyor speed
can be variably adjusted infinitely by turning knob 4 fig.3
(on the left, vehicle rear).
The floor conveyor return can be actuated by pressing button 8.
Fig. 3
Attention: Only reverse floor conveyor briefly
The fast run floor conveyor speed (special feature) can be switched
on from the toggle switch on the control box.

OPERATING INSTRUCTIONS
Mega-Trailer Page 15
6.2 Electro-hydraulics (special feature)
The hydraulic system can be driven as an open system with max. 80 l. /min. The tractor requires a double- and a
single-acting control valve with free return (red=supply;blue( thick hose)=return for the hydraulic connection.
A free return directly to the hydraulic oil tank is preferable as it involves less tailback pressure. The flow regulator
for the neutral circuit and the speed adjuster for the small consumers such as pick-up, the articulated drawbar,
tailgate etc. are to be found in the pump inlet plate. The speed adjustment for consumers other than floor conveyor
and cross conveyor is regulated from the adjusting screw (1). The flow rate can be set from 1 – 16 l. / minute.
If the tractor control valve is actuated, oil flows through the hydraulic system.
(Attention: Always ensure correct flow direction!)
The tractor control valve lever should always be locked in
place so that it does not have to be held onto constantly.
The functions required can now be selected directly from
the control box using the toggle switches.
Attention: Before depressurising the hydraulic system again
via the tractor control valve, the toggle switches on the
electrical control box must be put to zero position.
High accident risk!
Fig. 3.1
6.3 LS – Connection
The self-loading trailer hydraulic system can be regulated with the tractor LS system. (The hydraulic pump’s pres-
sure and delivery rates are adjusted to current need).
For this purpose the LS connection on the tractor is connected up to the LS connection (2) fig. 3.1 on the self-
loading trailer control valve.
The supply is connected directly to the hydraulic pump.(Not via the tractor control valve).
Attention: Never use the pressure connection without the LS connection.
The pressure regulator must be blocked by screwing in the bolt (3) fig. 3.1 as far as it will go. The regulating
current cut-off must be set to open system.
Attention: If connecting via the tractor control valve, the bolt (3) will have to be screwed out again as far as it
will go.

8. Technical Data and Notes on practical Usage
1. The system can only be operated at 12 volts
2. Connecting terminal 15 / 30 – plus; 31 – minus
3. Hydraulic system maximum flow rate 70 l/min.
4. Hydraulic system maximum pressure 210 bar
5. Supply SN 16 (marked red)
6. Return SN 20 (marked blue)
7. Tailback pressure at tractor must not exceed 10 bar
8. Hydraulic block torque setting 25 – 28 Nm.
9. Control light bulb can slip out of its holder if not handled carefully.
10. Every unit must have an emergency hand-operated actuator. If the electrical system breaks down, the
magnets can be actuated with a sharp object.
11. When hitching, make sure that the hydraulic couplings are perfectly clean. If dirt gets into the hydraulic
system, malfunctioning is likely to occur.
12. The hydraulic couplings on the trailer must match those of the self-loading or discharge trailer. On certain
types of trailer, for example, John Deere, Ford or Fiat, the hydraulic couplings are fitted with a ball. If this
kind of coupling is used, tailback pressure or complete closure of the coupling can occur.
13. Protect the control box against humidity.
14. When driving for longer periods on the road, it is advisable to switch off the tractor hydraulic system.
This prevents the system from heating up unnecessarily.
15. During long downtimes the self-loading and discharge trailer electrical systems should be switched off
as otherwise the consumers connected up to it will cause the tractor battery to discharge completely.
