innovators in agriculture
What you feed
is what you get!
Harvest results
A million cows are milked daily by Lely robotic milking systems but it’s not only the
Astronaut that makes robotic milking such a success. It’s the knowledge and experience
of our employees that help farmers to achieve the best results with their cows.
That’s why we know – more than anybody else – that good quality roughage is the
basis of your success. It ensures good animal health, maximum fodder intake and avoids
additional cost for concentrates and additives…
Your forage harvesting is the start for good and efficient milk and meat production.

Lely Welger AP 530-830
Our experience, gained from over one hundred thousand balers and knowledge of
the most modern production technologies, is used in every single one of our balers.
Tried‑and‑tested technology, stable constructions and professional processing lead
to machines that cannot be beaten in terms of reliability and value for money.

the drive, should an unforeseen blockage occur. On the Welger AP 730
and AP 830, this function is fully automated with an auto-reset clutch. The double tines, made out of particularly high-quality spring steel,
also have special tine support plates. This feature also substantially
increases the lifetime of the tine.
Chainless drive
The packers and knotters must run in perfect synchronisation with the
ram. Whilst competitive balers use chains to drive these components,
Lely balers are fitted with torsion shafts and angular gears.
The timing of the packers, knotters and ram, which is set in
production, cannot move, whereas on other makes, every time a chain
is adjusted the timing is altered.

Secure synchronised chainless drive
In order to guarantee the accurate timing of all components over the entire lifetime of a
baler, the packers and knotters are driven entirely via torsionally rigid shafts and gears.
From the main hypoid gearbox, the drive is transmitted via a drive shaft and angular
gear to the packer, knotter and needle drive. No chains or belts are used; even the
pick-up is driven by a shaft. This increases reliability as well as minimising the amount of
maintenance work required. Complex work with tensioning and lubricating chains/belts
is a thing of the past.

Efficient Packer Feed
The Packer Feed consists of two self-deflecting packers (the
Welger AP 830 has three) which prevent blockages caused by foreign
objects and damage to the machine.
The self-deflecting packers, which do not require the normal shear
bolt, can deflect in the case of an overload and then automatically
reposition themselves ready for operation. After several ram strokes,
the blockage will be cleared. The benefits are clear due to the use of a
patented hydro packer, a further development of the tried-and-tested
self-deflecting packers.
Automatic needle drive
A double clutch ensures that the synchronised timing process is accurate
during normal operation of the baler. Should the machine be reversed,
the needles will be driven out of the bale chamber. This device is fully
automatic and makes complicated ram-stop devices unnecessary.
Compact knotter
Our experience, gathered from making more than one hundred
thousand balers, has been implemented in this area too. Just to name
one of the many remarkable benefits: the bearings of the knotter
device are completely maintenance free. Sealed-for-life
bearings make lubrication devices, which are often
used in this area and which are subject to
malfunctions, unnecessary.
11
Equipment for professionals
The easy opening and large guards which make all areas accessible are advantageous
during maintenance and repair work. To supplement the already high specifications of
the standard machines, there is a range of accessories available. An example of this is the
hydraulic drawbar device, which allows the driver to move the machine easily from the
transport to the working position.

Foldable bale chute
The bale chute and the trailer hitch allow swift clearance
of fields. Due to the bale chute being easily foldable, the
machine can be converted quickly from its compact transport
size to field ejection.
This is aided by the hydraulically operated drawbar device
installed on the Welger AP 730 and the AP 830 as standard
equipment, meaning that the machine can be moved quickly
and easily from the transport to the working position.
The knotter – robust and reliable
All Welger AP machines in this range are available with
the option of a wire-tying system. This system is well
known, as is the twine unit, for its sturdiness and functional
reliability.
The use of wire as a tying material is also advantageous
when the bales are used, as the steel wire can be
magnetically removed.
