Complex work with tensioning and lubricating chains / belts is a thing of the past.

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 with 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.

 

Automatic needle drive

A double clutch ensures that the synchronised timing process is accurate in 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.

 

Efficient Packer Feed

The Packer Feed consists of two (AP 830 has 3) self deflecting packers which prevent blockage caused by foreign objects or damage to the machine. The self deflecting packers, which do not require the normal shear bolt, in the case of an overload the packers can deflect 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.

 

Compact knotter

All AP machines in this range are available with the option of a wire-tying system. This system is well known the same as the twine unit by 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. Our experience gathered from making more than 100,000 balers has been implemented in this area, too. Just to name one of 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.

 

Main drive with overload protection

Two friction clutches; one in front and one behind the flywheel protect the universal joint and the tractor as well as the baler drive. On the AP 530 and the AP 630, an additional shear bolt protects the drive should an unforeseen blockage occur. On the AP 730 / 830, this function is fully automated with an auto-reset clutch.

 

Pick-up tine bars fitted with ball bearings

In contrast to many other manufacturers, Lely uses strong, maintenance free ball bearings for the tine bars. This high specification construction quickly pays off in terms of the service life.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.

 

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 specification 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 transport to working position.

 

Bale thrower P 23

The bale thrower P23, available for all Lely Welger high density balers, is an accessory available for farms where just one employee brings in the bales. The thrower, driven via its own hydraulic system, allows maximum use of the baler’s performance, as it is no longer restricted by the speed of a manual worker during loading. Using a Bowden cable control, the throwing range can be adjusted easily. This can be calculated according to the bale weight as well as the position of the trailer. The bale thrower can be adjusted using the specialised hydraulically operated drawbar device. This achieves even loading of the trailer even under poor conditions, i.e. side winds or steeply sloping fields. In a few easy steps, you are able to convert to normal field ejection.

 

Advantages:

• Field clearance by just one person.

• Optimum loading of the transport trailer via the thrower range control.

• The side pivot device allows optimum trailer loading even in strong side winds or on steep slopes.

• Can also be converted to normal field ejection

 

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 AP 730 and the AP 830 as standard equipment, meaning that the machine can be moved quickly and easily from transport to working position.
