The versatile KUHN SW 4014 square and round bale wrapper provides fast, cost efficient and operator-friendly wrapping. The laser-guided, patented AutoLoad function detects, loads, wraps and unloads bales automatically, creating a more ergonomic and stress-free working environment. This wrapper features a solid design and a hydraulic sliding frame that allows unique drive-through operation. This provides the ability to widen the wrapper for easy bale loading, outstanding stability and unmatched visibility of the wrapping process. The Autoswitch function enables the wrapper to fold from transport position into field position with a single push of a button on the ISOBUS terminal. KUHN exclusive pre-stretchers, combined with IntelliWrap controls, provide excellent distribution of the film applied around each bale with further film savings.

Design Features with YOU in Mind

Optimal Versatility

The SW 4014 can wrap large square and round bales up to 3,300 pounds (1,500 kg). Wrapping of round bales is possible without any additional equipment or mechanical adjustments. All predefined bale dimensions can easily be selected via the monitor.

Unique “Drive Through” Design

Thanks to its solid design, with incorporated hydraulic sliding frame, an extremely wide track is achieved for outstanding stability of the machine. This unique “drive through” operation enables easy loading of the bale and excellent visibility of the wrapping process.

The Autoswitch function enables the wrapper to fold from transport position into field position with a single push of a button on the ISOBUS terminal. The wrapper is 13’ in field position and folds to a narrow 8’ for transport.

Exceptional Bale Handling

The smart “drive through” design of the SW 4014 guarantees easy (un)loading of the bales, front- and backwards, even when dropped in hard-to-reach locations. All bales are (un)loaded without the risk of damaging or soil contamination because of the two pair of steel rollers. To prevent film damage during transport, the SW 4014 is fitted with large wheel covers.

Easy Maintenance and Accessibility

The large side doors of the SW 4014 provide excellent accessibility for maintenance. The SW 4014 can be equipped with an optional LED work light for a better view of the wrapping process in the dark.

Non-Stop, Fully Automatic Wrapping

Non-Stop Wrapping With Autoload

The innovative AutoLoad function provides non-stop, fully automatic loading, wrapping and unloading of square- and round bales without input from the driver. AutoLoad detects approaching bales, automatically scans the length of the bale and sets the loading arms into pre-load position, resulting in accurate loading, wrapping and unloading of the bale on the go. This leads to increased overall capacity and creates a more ergonomic and stress-free working environment during a long working day.

How Does It Work?

AutoLoad is based on Category II Laser technology. The laser sensor, situated inside the top cover of the machine, scans the area ahead of the bale wrapper. In addition, a wheel sensor is placed on the left wheel which measures the speed and distance traveled.

Laser sensor is measuring ground level.
Laser sensor has detected the bale.
Laser sensor has detected the edge of the bale. Bale length measurement starts by counting pulses on wheel sensor. Loading arms move to pre-load position (based on pre-defined bale width).
Laser sensor has detected the end of the bale. The bale length is known.
Depending on the driving speed, the loading arms are activated at the right time to load the bale in the center of the rollers with no need to stop.
While wrapping, it is possible to drive to the next bale.

In case bales are dropped in ditches, under fences or even in corners of the field, the SW 4014 AutoLoad still allows you to load bales manually, forwards and backwards.

High-Speed, Intelligent Wrapping

Twin-Satellite Design

The twin-satellite design ensures high-speed wrapping. The standard pre-stretchers, which each hold a 30” (750 mm) roll, are made of aluminum to avoid build-up of tack from the film. Both outer ends of the aluminum rollers are cone-shaped to maintain the optimum width of the film and reduce the risk of film tear. The special ribbed profile of the aluminum rollers keeps air and water away from the film. The location of the pre-stretchers makes it easy to change the film rolls. The standard pre-stretch of 60% is reached by a low-maintenance and low-noise gear transmission.

The positioning of the shorter top rollers allow the film roll holders to be positioned as low as possible. As a result, the film is wrapped closer to the center of the bale with less wrinkling, ensuring an optimum oxygen barrier for excellent silage quality.

Once the desired number of film layers has been applied, the film is then held firmly and cut by two “scissor-type” film cutters. The film is held with a clamp, gathered into one solid rope and then cut before the bale is unloaded. The clamp firmly holds the film ready for the next bale.

IntelliWrap

Greater management and control of the wrapping process can be achieved by our unique IntelliWrap control system. IntelliWrap uses sophisticated electronics and hydraulics to monitor the wrapping process and continuously controls the film overlap, allowing total flexibility. Depending on local field conditions, crop and storage periods the amount of film layers (4, 5, 6, 7, 8, 9...) can simply be adjusted. An excellent distribution of the film around the bale and precise overlap of the film provides maximum efficiency and increased silage quality.

Selection of five film layers
The bale is covered with three layers and 67% overlap
Bale rotational speed is increased
Final two layers with 50% overlap

Equipment

CCI Terminals

The SW 4014 is ISOBUS compatible. ISOBUS compatible tractors will therefore not require a separate control terminal for the wrapper. Alternatively, the CCI 50 or CCI 1200 monitor can be used with tractors that are not ISOBUS compatible. Operator settings, such as selecting bale dimensions and switching from transport into field mode, are accessed via the monitor. Information, such as wrapping process overview and number of bales, is also provided.

Full Visibility

To provide optimal visibility and safety around the machine, the SW 4014 can be equipped with a KUHN camera system. There are two kits available, one kit is compatible with the CCI terminal, and the other one consists of a separate monitor and a camera.
