4. The functioning of the bale collector
See the assembly drawings in chapter 10 for the order of positioning of the bales.
1. The first three bales of the Limo Hydra 8 are pushed sideways by the spiral rollers.
For the Limo Hydra 15M this applies to the first four bales.
2. The red lever operates the mechanism partially (photo A, position 1).
3. The fourth bale (the fifth bale for the Limo Hydra 15M) triggers the second lever
completely (photo A, position) which unlocks the smaller roller (photo B) that folds down
for the first time. The first set of bales are now transported to the tailgate.
4. At the Limo Hydra 8 the plate on the tailgate will be pushed down by the bales after the
first set of four bales (photo C).
5. At the Limo Hydra 15M the second set of five bales pushes down the flap that is above the
roller (photo D).

Photo B —Unlocking smaller roller

The smaller roller will spring back to its idle position. After that, the next set of bales will fill
the forward half of the collector. The last bale on the collector will operate the mechanism
and consequently the smaller roller will be unlocked. As a result it will fold back again. The
smaller roller will now also trigger the tailgate which will tilt backwards. In that moment a
hydraulic motor assures that the rollers are turning around at maximal speed so that the
bales are discharged quickly and close to each other. When the bales have left the collector,
the smaller roller and the tailgate will switch back to their idle position and the process will
start from the beginning.

5. Installation, starting up, adjustment
Check if the bale grab is undamaged and in good condition on delivery. Please contact the supplier
or Meijer Holland if you notice any damages. Only use the bale collector if it is found to be in good
order and after this manual has been read.
Make sure that the baler and the collector stand horizontally.
5.1 Installation
1. Remove the standard platform that is attached to the baler.
2. Drive the tractor up to the collector so that mounting surface of the baler is as close as
possible to the mounting point of the bale collector.
3. Make sure that the machines stand on an even ground during the installation of the
collector.
4. Mount the supplied platform (photo E) to the Limo Hydra.
5. Mount the platform to the baler with the respective pin (photo F) and the shore strips.
The platform with the shore strips works as a kind of funnel. It assures that the bales fall
gradually on the collector and not too close to each other.
6. See the example for a complete assembly (Photo G, page 9).
7. The strips, the platform and pin must always be secured properly.
8. Connect the supply lines and return lines to the baler. The bale collector is supplied with
the lines until the press channel. A single acting valve with a unpressurised return flow is
required.
9. Check that there is no leakage and that the rollers rotate in the correct way (Photo H,
page 9).

6. Operation and use
1. Adjust the bale guides
Before the use, the four red bale guides must be adjusted to the correct width of the
bales. Adjust the bale guides in such a way that the device can be operated optimally and
that the bales are moving smoothly on the machine. The two front bale guides should be
closer to each other than the last ones. This prevents blockage.
2. Adjust flow control valve
The speed of the spiral rollers can be adapted to the capacity of the baler by adjusting the
flow control valve (photo I). Don't open it completely, as the rollers must be able to
rotate faster when the bales are being discharged. This acceleration is powered by the
latching valve that simultaneously opens with the tailgate (photo J).
3. Adjust spring tailgate
Adjust the spring (Photo K) in such a way that the tailgate will spring back to its ideal
position after the bales have been discharged. A spring that is to tight can cause the
tailgate to close to quickly during the release of the bales, because of this the bales won’t
be placed in the right position. This may also result in that the tailgate will be launched
back too hard in it’s initial position, in wich case it isn’t locked properly. Hereby the
tailgate will open with four bales in it already. It may also happen that the tailgate doesn’t
hit the flow control valve, in this case the machine will make the rollers rotate to quickly.
4. Adjust spring smaller roller
Adjust the spring (Photo L) in such a way that the smaller roller, after releasing the bales,
that will launch back in its starting position. To much tension on the spring can cause the
valve to close during the passing of the bales. Because of this the bales won’t be placed in
there optimal position on the back part of the Limo, the bales can get jammed in the
machine. If there is not enough spring tension the roller won’t return in its locked
position after releasing the bales, in this case the roller will release the next batch of bales
to early.

5. After use
1. Place the bale collector with the tractor on a solid and even ground.
2. Disconnect the hydraulic hoses and check them for leakage.
3. Dismount the junction of the tractor/baler from the bale collector and drive the
tractor straight away.
Assure that the bale collector is stored in a dry and clean environment until the next use.

7. Maintenance
Regular maintenance extends the life span and prevents injuries, leakage of hydraulic oil and
damages.
Maintenance schedule
Before every use
Check the bale collector for damages and wear. Replace damaged or worn
parts immediately.
Check the hydraulic clutch, hoses and cylinders for leakage, wear and
damages. Let problems be fixed immediately by a competent mechanic.
At least once a week
Clean the collector of caked dirt and dust. When using a high-pressure
cleaner, avoid the electrical parts.
Put grease on the grease nipples. At extensive use:
after every 8 working hours add a bit of grease (0,86 grams per grease
nipple).

8. Problems and solutions
The bale collector is composed by several moveable parts. Repair or replace damaged or
worn parts immediately. Spare parts are available at Meijer Holland or at suppliers.
Hydraulic fluid is a poisonous liquid that is harmful to the environment. Never
try to shut a leak with your hand. Fluid under high pressure easily penetrates
through skin and clothing and can cause serious injuries.
Assure that the baler and the tractor are turned off and that turning and moving
parts are blocked during repair works. Do this to prevent entrapment.
In case welding works are performed at the bale collector, assure that the bale
collector is completely disconnected from the baler and tractor. If this is not
possible, uncouple the battery of the tractor.
