Welger RP 445

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.servicing.

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.

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.

Always in the centre of the bale chamber

Throughout the baling process, the core of the bale always remains in line with the crop feed system and the heart of the bale chamber. The tail gate even changes its position during the baling process. This geometry is hugely important for bale size and bale rotation and is the only way to make perfect bales.

Mechanical tail gate locking system – time saving due to uniform bale and fast tail gate

To ensure minimum differences in terms of bale diameter, two mechanical hooks secure the tailgate once it’s fully closed and ensures that it remains so throughout the baling process. This locking is linked to the two single acting rams of the tail gate; these rams can open and close the tail gate far quicker than double acting rams on a baler with a hydraulic locking system.

Full speed right from the start

When starting a new bale, the operator can start at full speed. This is because the four belts of the baler take up the crop material effortlessly, right from the start of the baling process. The two big springs that form part of the CPS system ensure correct bale density right from the core. This benefits bale formation and ensures a properly structured bale core, which is very important for the end product. The big springs have a great capacity for adaptation, which provides space for the belts; they can easily absorb the major L/H - R/H differences in bale diameter.

High density on the outside doubles your bale weigh

After the core of the bale has been formed, the hydraulic system is activated. Hydraulics react more gradually to changes than a mechanical system and can be controlled better. The hydraulic system keeps building up pressure until the pre-set density is achieved. The intelligent construction of the belt tension device and the position of the CPS rams make sure that the tension on the belts increases proportionally to bale circumference. Thus, the CPS ensures a constant density achieving maximum filling.

Bale density adjustment

The pressure that the hydraulic system transfers to the bale is manually controlled by RP 415 – RP 445 with BCE or through the E-link control in the tractor cab.

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 thereby improving feed quality.

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.

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.

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 onto the chain. The large capacity of the oil reservoir means oil does not have to be replenished on a regular basis.

Endless belts for the longest lifetime

Two core inserts made of special synthetic material allow particularly high tensile loads. These layers are securely manufactured with a large overlap, independent from each other. No joiner, no problems!

Powersplit – Designed for outstanding performance

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.
