2.3. Design and operating principle of the big bag fertiliser suspended loader

The general design of the big-bag fertiliser suspended loader is shown in g. 6.

Fig. 3 Design of the arm.

1 - support frame; 2 - upper arm; 3 - extended arm; 4 - support assembly; 5 - extension

actuator; 6 - lifting actuator; 7 - warning plate with lamp.

(1) is a support frame designed as an open welded structure made of sections and high-grade
steel sheets. The upper part of the frame features the mounting opening for the upper arm. The
middle part has eyes for the upper arm lifting actuator. The frame can be attached to a three
point hitch on a tractor and on its other end, it allows coupling with a spreader. The compatible

18

spreaders are N061 standard versions from Metal-Fach; other spreaders can be coupled via
adapters.

The upper arm (2) is made as an open welded structure and serves as the guide for extending
and retracting of the extended arm. It has welded bushes at the other end for articulated coupling
with the support frame. The lower part features the mounting opening for the lifting actuator.
The upper part has eyes for the lifting actuator.

The extended arm (3) is a welded structure that increases the working range of the upper
arm. At its end, the arm has a hook with the adequate strength class for hooking of big bags.

The support assembly (4) is a welded structure used for secure resting of the arm on a hardened
ground after decoupling from the tractor. Children must not approach the machine, especially
when it is in the position explained above. The actuators (5) and (6) are used, respectively, to
extend the upper arm and to lift it in the horizontal plane.

3. Operation

3.1. Coupling the arm with the tractor

The fertiliser big bag loader can be directly coupled with the three point hitch of a tractor.
When coupling, the loader must rest rmly on a level and horizontal ground, supported by
the support frame and the support assembly. Depending on the tractor's design, couple the
bottom links with the top or bottom holes. Depending on the fertilising method (pre-sowing
or top dressing), couple the spreader with the appropriate holes. Use the top coupling holes for
standard fertilisation. The bottom holes are for late fertilisation and ensure that the machine
runs higher. After installing and securing the lower link pins, set the top coupler height, install
its pin and secure it.

Always mind that no one must remain between the tractor and the machine when approaching
the latter with the tractor. Only one person, the operator, shall couple the two machines.

Warning!
Use of non-standard safety measures (bolts, wire, etc.) to
couple the links and the coupler with the machine may result
in accidental release of the coupled machines and an accident.

Fig. 9 Coupling the arm with the tractor and the spreader (1) – Cat. II pins

of the lower coupler link; (2) – Cat. II pin of the top link

24

Use the original and operable cotter pins to secure the links and the coupler pins.
Limit the side movement of the bottom links to + 2.5 cm with bars or stabiliser chains.

Warning!
Before coupling the machine with the tractor, calculate the
required load of the front axle. Additional weights may be
necessary. Install them according to the tractor manufacturer's
guidelines. The minimum front axle load is 20% of the tractor's
kerb weight.

3.2. Installing the PTO drive-shaft

The spreader coupled with the loader frame shall be coupled with the tractor's PTO. Couple
the machine's drive system with the tractor with the machine lowered, the engine turned off and
with a shaft recommended by the manufacturer. The shaft shall be complete with guards, in a
proper technical condition and with a working decoupling safety.

Check that the catches fully secure the PTO drive-shaft ends.

Fasten the shaft guard chains – one at the tractor end, the other at the machine tow bar.

Warning!

Do not couple and operate shafts with damaged guards.

Warning!
If the drive shaft needs to be shortened, follow the applicable
instructions from its manufacturer.

Warning!
Danger of being caught by bare input shaft if the transmission
shaft is not properly installed! When installing the machine end
of the transmission shaft, the shaft guard bell must be properly
installed on the transmission neck and the input shaft must be
fully covered at all times.

25

3.3. Charging the spreader

Use extreme care when loading the fertiliser spreader with the big bag arm. Follow the

guidelines in these operating instructions.

The following table lists the general requirements for proper work with big bags:

Do the following to charge the spreader body with the fertiliser from the big bags handled by
the loader arm:

- Prepare the big bag for loading;

- Position the tractor at a spot that facilitates hooking up the load;

- Having coupled the fertiliser spreader, approach as close to the big bag as possible with

the tractor/loader/spreader unit;

- Operate the control levers to move the hook as close to the big bag sling as possible;

- Next, lower the arm until its support frame bottom part rests rmly on the ground;

- Make sure that the unit (tractor/loader/spreader) is stable;

- Turn off the tractor and remove the ignition key;

- Approach the big bag and hook it up to the arm;

- Check that the bag is properly hooked and close the hook safety catch;

- Start the tractor and operate the DCV levers to lift the big bag over the spreader hopper;

- Use the special tool to open the big bag and ll the hopper;

- Do not charge more fertiliser that the hopper capacity listed in the technical characteristics

issued by the spreader's manufacturer. Check for the correct weight of the fertiliser (in
the sowing tables) to avoid overloading the tank.

Warning!
No bystanders are allowed within the work zone of the machine
when loading with the big bag fertiliser suspended loader.

Warning!
Do not use any unauthorised components to extend the sling
when hooking up the big bags.

Warning!
Exceeding the permitted load capacity may damage the machine
and cause work accidents.

28

Warning!
The loader has been designed and tested (for strength) for lifting
loads with the maximum weight of 1000 kg. Do not exceed this

limit!

Do not charge fertilisers that are clumped, contaminated with foreign bodies or wet and

prone to leaching; this may reduce the performance of the spreader or incapacitate the spreader.

Identication and verication of the tractor's technical parameters for driving the loading
arm/spreader unit

Check the following before coupling the arm and the spreader with the tractor:

The permissible tractor kerb weight;
The permissible tractor axle loads;
The permissible tractor hitch load;
The permissible tractor tyre load;
That the permissible tractor hitch load is sufcient.

Warning!

6.1. Description of residual risks

Residual risk results from incorrect actions of the big-bag fertiliser suspended loader
operator.

The greatest hazards arise when bystanders (especially children) and animals remain within
the hazardous areas of the loader at work. The level of risk increases when warning labels are
ignored!

Extreme hazards include:

- remaining under the raised loader arm and the big-bag at work;

- humans and animals staying in the loader's work area;

- servicing and repairing the loader with the tractor engine running and the loader raised;

- use of cracked or deformed hydraulic lines;

- failure to keep a safe distance from power lines during work;

- controlling the loader while remaining outside of the driver's cab;

- operating the loader without verifying the tractor's parameters (i.e. installation of

counterweight).

The hazards do not occur when the operating instructions and safety instructions are

followed.

37

6.2. Residual risks assessment for operation and daily servicing of the
loader

Follow these rules:

1. Carefully read and fully understand the operating instructions.

2. Do not allow any bystanders to come near the arm at work.

3. Do not allow children to come near the machine at work.

4. Use the machine only as intended.

5. Wear tted clothes only, i.e. without any loose parts.

6. Only the operator (after thoroughly understanding the operating instructions and the

safety regulations) is allowed to operate the loader.

7. Inspections and repairs shall be carried out by trained personnel only.

8. Securing the machine for the duration of repairs and daily servicing will preclude risks

to the user.

Warning! The residual risks arise if you fail to thoroughly understand
