Baling pressure regulation and hydraulic feed

Claas offers the Quadrant 5300 scare baler with heavy-duty knotter for automatic baling pressure regulation and hydraulic feed. The baler comes with an Isobus terminal.

During the summer of last year, Claas introduced the Quadrant 5200 and 4200 heavy-duty knotter with automatic baling pressure regulation and active air ducting for bales measuring 70 cm x 120 cm. The company is now introducing this innovation for the 90 cm x 120 cm bale size, which is widespread in Europe, and replacing the current Quadrant 3300 model with the Quadrant 5300.

Achieving higher bale densities and more stable bale shapes along with a higher throughput were the main focus during the development of the new square balers, including the Quadrant 5300. As such, the torque of the feed rake and rotor coupling, the rotor speed and the length of the bale chamber have been increased by around 12 % for the 5300 model.

The single knotter is valued in operation for the reliability of its tying without the production of twine waste. In order to match the higher level of performance, the company has increased the overall size of the single knotter and redefined every single step of the tying process.

The knotter hook and twine retaining plate have been structurally altered to allow them to operate using longer twine ends. This means that the knots can now no longer come undone at high baling pressures. The heavy-duty knotter also works using active twine pressure control. This ensures the twine is held tight at the maximum clamping pressure when the bale is being formed, which is then reduced during the tying process. This places less strain on the twine, so balers can achieve optimal tying results even when using lower-quality twine.

A special feature of the Quadrant 5300 is the off-center needle control. This Claas patent ensures that the needle speed varies and that there is more time spent on the tying process. During upwards movement, the needle is rapidly accelerated, then remains at the knotter for a long time before being quickly pulled back down again. This guarantees optimal tying results, says the company.

With the patented automatic baling pressure control system, APC (Automatic Pressure Control), the Quadrant 5300 can also always be operated at its maximum selected output. To do this, the operator enters the desired bale density and quality of the baling twine being used in the Isobus terminal. Depending on these two values, which are measured by four sensors on the knotter and main frame, the baler automatically regulates the baling pressure itself. With the APC, even inexperienced operators can now achieve the maximum possible output for the machine and twine, and can produce bales of uniform weight irrespective of the quality of the baling material.

APC sensors are provided on three knotters. There is also the option to equip the APC with the KCS (Knotter Control System) with six sensors for knotter monitoring. With the KCS system, the operator can see the knotting quality of each individual knotter displayed on the terminal. The user interface of the balers' terminal can be individually adjusted to meet the needs of the driver. In addition to the Isobus-capable operator terminal, Claas also offers the Isobus Communicator II S10 operation as well as the Easy on board app' for tablets.

Active knotter cleaning

To ensure the knotter is cleaned effectively, the high-power Turbo Fan has been equipped with active air ducting. The focused air stream flows over oscillating pendulums at a speed of 140 km/h and is directed not just towards the front of the knotter, but the sides as well, ensuring that it remains free from residual material at all times and is able to operate without hindrance.

According to the company, with the introduction of the Quadrant 5200 last year, they became the first baler manufacturer to add a hydraulic feed. This has now been carried over to the Quadrant 5300. Thanks to the pick-up's hydraulic drive, Power Feeding System (PFS) and rear roller crop press, the speed of the feed can be regulated and can be reversed from the tractor cab in the event of a blockage, for instance when baling silage. This means that the driver can drive at the maximum output without concern, irrespective of the baling conditions. At the same time, the feed speed can be reduced for delicate crops such as lucerne hay in order to minimize leaf loss. The Quadrant 5300 will be offered in the Roto Feed variant without knives, as the Roto Cut variant with 25 knives, and with 51 knives with the Fine Cut cutting system.
