The innovative AUTOLOAD function provides non-stop, fully automatic loading, wrapping and unloading of square and round bales without interference from the driver. AUTOLOAD detects approaching bales, automatically scans the length of the bale and sets the loading arms into the 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.
The AUTOLOAD function is based on Category II Laser technology. First the laser sensor, situated inside the top cover on the front side of the machine, is scanning the area ahead of the bale wrapper. In addition, a wheel sensor is placed in the left wheel which measures the speed, thus the distance until the next bale.
The SW 4014 is capable of wrapping large square, medium square and round bales up to 1500 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.
Thanks to its solid design with an 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 touch of a button on the ISOBUS terminal. The wrapper has an operational width of 4 m in the field and folds to a narrow 2.5 m for transport.
To provide optimal working convenience, the SW 4014 has a smart feature that enables you to choose (automatic) unloading of bales in a selected position. You can choose to unload the bale with the knots on top for easier loosening of the twine and also quicker access to your feed after unwrapping the bale. Or, if required, you can unload on the short side for easy transport.
The large side doors of the SW 4014 provide excellent accessibility for maintenance. Furthermore you can open the top cover and side doors without the need of tools. The SW 4014 can be equipped with an optional LED work light to have a better view of the wrapping process in the dark.
The twin-satellite design ensures high-speed wrapping. The central driven satellite arms each hold one pre-stretcher with a 750 mm film roll. It rotates the bale applying the requested number of film layers while being protected by the safety arms.
The standard pre-stretchers are made of aluminium to avoid tack build-up 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 tearing. The special ribbed profile of the aluminum rollers keeps air and water away from the film. The location of the pre-stretchers makes it very easy to change the film rolls. The standard pre-stretch of 70% is reached by a low-maintenance and low-noise gear transmission. An optional 60% pre-stretcher gear kit can be installed to change the standard pre-stretch to 60%, to adapt to difficult wrapping conditions.
The wrapper is equiped with a high-speed double satellite with a boost function to increase the speed up to 40 rpm when travelling a forward speed of 5km/hr or higher. This results in a capacity of up to 100 bales per hour when applying 6 layers of film.
INTELLIWRAP allows greater management of your wrapping process. Continuously control the film overlap and required amount of wrapping layers (4, 5, 6, 7, 8, 9…) to match your local circumstances, crop conditions, and storage periods. An excellent distribution of the film around the bale applied with precise overlap, provides maximum efficiency and increased silage quality.
Once the desired number of film layers has been applied, the film is held firmly and cut. The well-known ‘scissor-type’ cutters hold and cut the film. Due to its design, the film is caught across the full width. The film is held with a clamp, stretched into one solid string, and then cut before the bale is unloaded. The clamp firmly holds the film ready for the next bale.
