Highly efficient operation
On a global scale, the differences between silage are huge. Climatic and field conditions will determine what is the ideal spec of your 245. There are a number of options available when it comes to chopping units, tying systems and lubrication systems as well as control facilities. The heart of the baler is constituted by the well proven 1.25 m diameter bale chamber with 18 Powergrip steel rollers. The bearings of these rollers can be tailored to all operating conditions. Choose a 245 to suit your requirements and experience many years of pleasant and highly efficient operation.
Wide pick-up – Large swaths
The RP 245 model has a 2.25 m wide free running pick-up with five tine bars. Pick-up capacity is huge; the long 5.60 mm tines have large coils and are therefore ideal to retrieve the crop from high stubble. Due to their great flexibility, the tines can easily adjust to uneven ground contours, thus eliminating contamination. Suspension of the pick-up is adjustable and perfect ground contour following is ensured in combination with the height chains and pick-up wheels.
The benefits of an efficient chopping device
• Lower costs per bale due to increased bale density.
• Increased forage intake by animals due to better conservation and feed quality.
• Time saving through ease of distribution at feeding time.
The additional investment in a chopping system is always worthwhile and therefore the Lely Welger RP 245 range offers three configurations with 13, 17 or 25 knives (Profi model).
Mastercut13 – affordable and rigid
The comprehensive range of state-of-the-art chopping units starts with the Mastercut13 – 13 extra-long knives, reaching deep into the ring of the rotor, ensure consistent chopping of the crop. Crops can be chopped to a bare minimum of 90 mm. The two-star rotor guarantees an impressive throughput assuring optimum output even in the heaviest of crops.
Xtracut17 – high throughput and ease of operation
The 17 knives of this chopping unit are divided in two groups of eight and nine knives which can be selected by the operator from the tractor cab. The 500 mm diameter chopping rotor has an exceptionally open construction ensuring that the spirally configured tines have a large grip of the crop. Due to this rotor construction, crop throughput to the bale chamber is massive ensuring high output when baling high volume crops.
Cleanest crop pick-up
It is not the only function of the two single-acting hydraulic rams behind the pick-up to lift or lower the pick-up; these rams – fitted with adjustable springs – also constitute the pick-up’s suspension. Due to these springs, the pick-up floats over the ground with a minimum weight, whereby the pick-up wheels operate as adjustable gauge wheels to ensure the correct working depth. At the moment when the pick-up needs to be lifted, the wheels can easily push the pick-up upwards. The maximum downward stroke is limited by two heavy-duty chains.
Highest quality machines
With over 100 years of baler experience Lely Welger RP balers set the standard in terms of quality and reliability. Some convincing examples: the rollers and intelligently engineered bearing housings which – even after years of baling heavy dense bales – require the least amount of maintenance.
Impressive silage operations
When operating in wet conditions and needing to bale large quantities of grass for silage this model exceeds all current standards. Exceptional performance and reliability are ensured by the Xtracut17 chopping mechanism with its huge appetite and by the 50 mm diameter roller shafts and heavy bearings (optional). The strength of these shafts ensures precise alignment of the sprockets minimising chain wear. The rollers which experience the heaviest loads are fitted with double race bearings on the drive side.
Lubricated bearing housing
The unique bearing housing on the Lely Welger RP fixed chamber round baler ensures stable alignment of all driving gears on the drive side of the machine thus eliminating undue wear and tear of chains. On the non-drive side, the sealed bearings can shift in their housings so that the lateral forces exerted by the pressure onto the bale chamber are perfectly absorbed. The unrivalled bearing system of these balers ensures lowest possible maintenance costs and supreme reliability.

New pick-up for modern baler
The new free running pick-up of Lely Welger RP balers has been designed as a result of the increased output from these machines. Improved crop throughput to the bale chamber has eliminated the need for the specific movement of a conventional pick-up. With no cam track the pick-up consists of fewer moving parts. It is more reliable, less sensitive to wear quiet and maintenance free.
More tine bars – cleaner pick-up
Due to the additional space created through the absence of a cam track and cam followers, 5 tine bars are now fitted to the pick-up. Along with the 64 mm interspace of the tines this allows a 25% increase in pick-up capacity resulting in an even better and cleaner pick-up of the crop.
New pick-up – new tines
The tines are the most crucial parts of a pick-up and therefore a completely new tine has been developed for this pick-up.
- The angle of the tine has been adjusted to ensure the cleanest possible pick-up under all conditions.
- The longer tine is more flexible and featuresi mproved adaptation possibilities.
- The tine is made of material with a 5.60 mm thickness, which favours tine life. Due to the larger coil, the tine remains flexible.
- Improved tine fixation prevents tine breakage as the tension within the material is more evenly spread.
Closer to the rotor – improved crop throughput
Due to the more compact construction the new pick-up is closer to the rotor. Consequently the rotor removes the crop from the pick-up easier ensuring improved crop flow, especially with awkward, short material, this is transported to the bale chamber far more efficiently. Improved crop flow means a better bale shape, plus increased output.
Wear-resistant and maintenance-free
Since the new free running pick-up does not have a cam track, the pick-up unit consists of fewer moving parts. It is more reliable, less sensitive to wear, quiet and maintenance-free.
- The new camless free running pick-up by Lely:
- Boasts high capacity thanks to good crop flow.
- Power saving due to not having cam followers.
- Has fewer moving parts because there is no need for a cam track.
- Is maintenance-free because the components need no lubrication.
Crop press roller
The crop press roller assists the pick-up when handling a smaller crop volume, ensuring efficient flow due to its rotation. The roller is also improving bale shape by evening out large quantities of crop without creating lumps. This roller is a quality and output increasing factor at all times.
Chopping silage improves your results in many ways
Lely Welger offer many options when choosing a chopping system for your baler. Initially this may seem like an additional investment but chopping the crop will help improve the quality of your forage and thereby your results in so many ways that you actually need more reasons not to choose one.
Xtracut – extra output and additional comfort
To ensure optimum performance when chopping, Lely Welger have designed the Xtracut17 and Xtracut25 chopping mechanisms with selectable knife banks. The operator can select from the E-link control box in the cab various knife bank selections when baling different crops, which is ideal for contractors. Both machines have two sets of knife banks that are hydraulically protected. So on the Xtracut17 you have an option of not chopping, or 8 or 9 or 17 knives engaged. On the Profi you have a choice of not chopping, or 12 or 13 or 25 knives engaged.
Chopping length’s that can be easily adjusted
From the tractor cab the operator can – via the E-link control – easily adjust the chopping length required by using both knife banks at the same time, or disengaging one. For the Xtracut25 this means a chopping length of 45 mm when all knives are engaged, or 90 mm when using 12 knives. Otherwise both groups can also be disengaged.
Always sharp knives
Timely changing of knives ensures a proper chopping action, reduced fuel consumption and also eliminates excessive wear of knives. The Xtracut option offers flexibility to the operator using one bank of knives. When necessary the second bank of knives can be engaged in one simple operation from the tractor cab ensuring continuing high output with a new sharp set of knives.
Chopping for higher density bales
Chopped hay, straw and silage crops are much easier to bale due to the reduced length and elasticity of the forage. This ensures heavy dense bales are produced leading to a reduction in handling, transport and twine/net tying costs.
Chopping to improve feed intake
Silage that has been harvested will ferment much better due to the sugars in the crop being readily available. This results in tastier fodder, which has a positive effect on the roughage intake of animals. In addition, short crops are generally digested better.
Chopping saves time through easier distribution at feeding time
Chopping the crop will avoid the build up of material and prevent blockages on the moving parts of diet feeders, forage boxes and straw choppers etc. Shorter material is also easier and faster to distribute.
Hydroflexcontrol – output is determined by throughput
Often the time for harvesting is limited and sometimes operators overstep a balers limits in terms of overload capacity. These limits are determined by the narrowest passage of the machine, which is decisive for its output. With balers, the space underneath the rotor is the critical factor. The Hydroflexcontrol anti blockage system increases this room in case of peak loads while at the same reducing downtime as a result of an inadequate forward speed or sorting out a blockage.
Flexcontrol + Hydroflex = increased baling output with less downtime
The two functions that are hidden in the name Hydroflexcontrol relate to the hydroflex floor which is underneath the rotor. The flex part avoids blockages; the hydro part solves blockages as and when they may occur. All Lely Welger balers with a chopping unit can be fitted with the Hydroflexcontrol system.
Flexible floor deals with peak loads
Flexcontrol is situated under the rotor where the feed passage is at its narrowest. It allows movement of the front part of the feed chamber floor to flex up and down via a rubber suspension – hence the word ‘flex’. If a small foreign object or a wet lump of material is picked up from the swath, this flexing action smoothes out the crop flow reducing the risk of blockages in the feed area.
Dealing with blockages from the tractor cab
The second feature is a hydraulic stage, whereby the rear of the feed table floor can be lowered hydraulically from the tractor seat to free the rotor of any blockage. When lowering the feed table floor the fact that all knives are also withdrawn ensures the blockage has passed into the bale chamber without any crop wastage before the operator re-engages the machine.
Saving time and money…
Net/twine tying, wrapping, transport and storage are all costs associated with baling. Less bales means lower costs. The bale chamber of a Lely Welger round baler produces the heaviest bales in today’s market place thus saving you time and money.
Bale rotation and pressure are critical for bale density
Bale rotation and pressure are critical for bale density The bale chamber which is fitted with 18 Powergrip steel rollers is critical for bale density. It is of paramount importance that all rollers keep a firm grip on the bale at all times. The number of bale rotations and the pressure exerted on the bale will directly influence final bale density. Therefore the bale chamber needs to have a perfect round shape and be fitted with rollers all around with the bare minimum of space between rollers to ensure maximum contact between the rollers and the bale. The mechanical tail gate locking system ensures that consistently sized bales with the highest density are produced every time.
Powergrip – maximum grip ensuring maximum bale rotation
The 18 Powergrip steel rollers ensure the highest bale compaction and excellent baling performance and rotation under all operating conditions. In a special manufacturing process the ten longitudinal ribs on each roller are pressed into the thick walled 3.2 mm tube. With each roller being seamless, the material structure gives the rollers an unequalled strength and a lifetime that is truly unrivalled in the market place. This unique Powergrip design is a patented feature of Lely Welger round balers and enables the balers to work with all types of materials in virtually every condition.
Mechanical tail gate locking system
All Lely Welger round balers feature a mechanical tail gate locking system. Two heavy-duty hooks secure the tail gate once it is fully closed and ensure that it remains completely closed throughout the baling process. These hooks are linked up with high-grade rubber blocks which increase the pressure that the bale chamber exerts on the bale. Bale density is determined through accurate measuring of the position on the tail gate hooks. This mechanical system can withstand the highest of pressure and it is not liable to the loss of pressure as in hydraulic systems. The result is evenly-sized, high density stable bales with little or no crop loss. Opening the tailgate goes fast and is very easy as only a single-acting hydraulic connection is required for opening the tail gate.
Effective tying saves costs and time
Making a perfect bale is one thing – preserving the bale for a longer period of time is a different matter…a variety of methods for storing, preserving and feeding bales necessitates a flexible tying system. Correct use of tying material limits costs, reduces the time required for tying the bales which in turn increases output per hour.
Varionet – for perfect bale coverage every time
We don’t just accept high-density bales, they should also look good. The Lely Varionet net wrapping system works perfectly with all standard net widths. Thanks to exhaustive testing, the well-proven tensioning system and a special net spreading device, the net wrap is consistently applied across the bale. Wide net wrap will even reach over the edges of the bale. This means that not only do the bales look great; they are also completely protected against bad weather conditions and crop losses. This process also eliminates any unnecessary air pockets,
Varionet wrapping with Easy Load System (ELS)
The well-proven net wrapping system has ELS which allows easier loading of the net roll from ground level from the left-hand side of the machine. After loading the new net roll is simply tipped backwards with the storage container, lifted into the operating position via the spindle and then locked into position. A spare nett roll can then be located in the frame ready for use. It couldn’t be any easier and will save you time and effort, thereby improving feed quality.
Variotwin – secure, fast, economically viable
The unique feature of this twine tying system is the variable speed control. This device allows for a sufficient number of twine rotations at the bale edges, enabling the bale to be tied quickly and ensuring that the ends do not fall apart. In this way even the lightest of crops can be tied quickly and securely in a cost effective manner.
Combination wrapping – double tying, double protection
All Lely Welger balers are designed to allow simultaneous twine and net-tying. This can result in up to 30% savings in wrapping material costs while in addition minimising crop losses.
Strength and Reliability
Unique roller bearings eliminate undue wear and tear
‘Flexibility’ is key when it comes to absorbing major forces in various directions. By ensuring that the rollers and the bale chamber can move in respect of one another, a major axial load onto the bearings of the rollers is eliminated. For this reason, Lely Welger round balers use unique bearing housings. On the drive side the bearing housings fitted allow the bearings to move slightly so that aligning of the gears always remains intact. However on the non-drive side the bearings can move in their housings; thus, the movement of the bale chamber is absorbed. Consequently, the pressure that the bale exerts on the side walls of the chamber constitutes a very minimal axial-load for the bearings, which greatly increases their lifespan. Just like the bearing housing on the drive side, these special bearing housings can be fitted with a lubrication system ensuring a moving action even in the most aggressive and wettest of conditions.
Environmentally friendly chain lubrication
Small swaths and wet crops constitute the heaviest conditions for a baler’s drive chains. The automatic chain lubrication system ensures that all baler drive chains are constantly lubricated with oil ensuring a long lifetime. The quantity of oil can be adjusted for each chain and brushes apply the oil directly on to the chain. The large capacity of the oil reservoir means oil does not have to be replenished on a regular basis.
Roller lubrication – guaranteed performance and output
Wear and tear caused by adverse weather and working conditions while baling silage is most effectively counteracted through regular lubrication of the rollers. This is made easy with the centralised and easily accessible location of the greasing block for the rollers.
Pick-up fitted with ball bearings
Lely set new standards here with a 2.25 m pick up consisting of four strong round steel tinebars consisting of 30 tines. Specially sealed grooved ball bearings ensure not only low power, they also exceed the service life of a normal bearing many times over. Precise height control is achieved through a spring balanced hydraulic lifting device and accurately adjustable guide wheels. The Lely Welger pick-up that is unique due to its large capacity as well as an exceptionally long service lifetime.
Powersplit – split power drive concept
Machines with a massive throughput need a drive system that is able to withstand the consequent high loads. The Powersplit transmission equally divides the amount of power required by the rotor and the bale chamber. This split drive train reduces the amount of horsepower required.
