KUHN's goal is to develop balers that boost the profitability of your baling operation. High output is an essential factor for all large square balers. KUHN's large square balers are designed with simple, yet efficient techniques that provide the capacity your baling operation requires. The ability to produce top quality bales in all crop conditions sets KUHN large square balers apart from others. Perfectly shaped bales, combined with high output and outstanding durability, ensure the KUHN square baler will be a profitable investment.

Square balers produce rectangular bales of various crops such as straw, hay and forage. Depending on the bale size we can distinguish two types: small square balers and large square balers (or bigbalers).
For the large-scale livestock farmer, contractor and energy crop producer, a large square baler is ideal. To ensure profitability, they must have a high output with a high bale density and minimal downtime. To chop the straw for forage, bedding and feeding the baler can be equipped with a cutting system or a pre-chopper.
Large bales are suitable for hay, straw and energy crop production. Bigger bales are not only more economical, they also need less handling because they can contain higher volumes at once. The large square bale is the most economical alternative for shipping because of its weight to volume ratio. Sizes range from 80x50cm to 120x130cm.
Horse owners or smaller farms regularly opt for small square bales. Thanks to their low weight (around 20-25 kg) and small size, they can be easily moved, stacked, and stored by hand. Several sizes are available, such as 45x40cm or 45x45cm.
For large square bales 80x90cm (3' x 3'), 120x70cm (2' x 4') and 120x90cm (3' x 4') are the most common sizes. But there are more possible sizes, ranging from 80x50cm to 120x130cm.
The weight of the bale depends on the bale density, crop type, crop humidity, machine type and bale size of course. Small square hay or straw bales weigh approximately 20-25 kilos. Large square hay or straw bales weigh approximately 450 - 550 kilos. The target weight for large square bales made of silage is 1000 kilos.
Square balers offer higher crop compaction and capacity than round balers, because square balers are non-stop balers and do not have to stop to bind the bale like round balers do. Their enormous throughput and steady crop flow allows them to produce large quantities of bales per hour.
Square bales are heavier, are more stackable and there is no empty space left between them. A square baler is therefore more often used for baling dry crops in combination with long distance transport. Round balers are more often used on and around the own premises, and are versatile from very wet crop to dry crop.
Square bales are always bound with twine. Round bales can be bound with twine, net or film.
The pick-up, rotor and feeder fork deliver the crop to the pre-compression chamber or pre-chamber. Here the crop is collected and compressed into a flake (or wad). Then the bale is formed in the bale chamber by compressing flakes by a plunger. Lastly the bale is knotted by a single or double knotter system. The bale automatically leaves the bale chamber via the chute. The bales are weighed on the chute if applicable and deposited in the field. The operator controls the machine via the ISOBUS-compatible terminal.

Square hay or forage bales can be wrapped by a bale wrapper. By wrapping a bale, feed quality is maintained and storage time is extended.
There are many different square bale wrappers on the market. Some models can wrap both round and square bales, like KUHN SW bale wrappers: Square & Round Bale Wrappers | KUHN
The SW 4014 is a self-loading model for non-stop, fully automatic loading, wrapping and unloading of square and round bales without interference from the driver.
KUHN is the only manufacturer in the world that offers both large square balers and square bale wrappers. So choosing KUHN means choosing exceptional expertise in square bales.
Large square balers are very versatile. They are used to bale crop residues such as: wheat straw, barley straw, oat straw, maize straw, rice straw and sugar cane. But they can also be used for grass (silage), hay, alfalfa and rapeseed. Large square balers are also increasingly used in energy and biomass crop production such as hemp and miscanthus.
The advantage of higher bale density is that you get more weight of crop in your bale. This increases efficiency in storage and transport.
In a large square baler the plunger takes care of compaction of the crop. Compaction or pressure is expressed as force on a surface area. KUHN divides the plunger in two so that the same force is applied to half of the surface area. This results in higher compaction per square centimetre. This is called the TWINPACT double plunger system, available on the KUHN SB 1290 iD model. The baling pressure is adjustable from the tractor cab on the terminal.
KUHN large square balers set new standards in capacity, bale shape, uptime and running costs. The main advantages are:
KUHN balers can be supplied with a single axle or tandem axle. You can choose different tyre options to suit your needs, e.g. wide tyres to minimise soil compaction.
The cutting system consists of 23 knifes with individual knife protection. The operator benefits from optimal comfort thanks to the heavy flywheel, last bale ejector, automatic greasing system and load sensing hydraulics.

One of the last steps in creating a perfect bale is the knot. You can choose a baler with a single or a double knotting system. KUHN large square bales are equipped with a double knotting system which offers more reliability and can handle higher bale densities. This is how a double knotting system works: The bottom needles bring the twine from bottom to top of the bale and bring the bottom twine and top twine together in the knotter to bind off the bale. The top and bottom twines are then brought back together to knot together for the start of the next bale. And all in 1.3 seconds.
To achieve the best results, we recommend using KUHN Twine. KUHN Twine is available through your KUHN dealer.
The quantity of twine depends on the size and the number of bales you produce. With the KUHN Film, Net and Twine calculator you can estimate the volume of crop packaging products you need per year. In just a few clicks you know what to buy and how much you can save!
KUHN large square balers require a minimum PTO power of 77 kW / 105 horsepower up to 144 kW / 196 hp. For more information, please consult the specifications on the relevant product pages: SB 890 / SB 1270 X / SB 1290 / SB 1290 iD.
