Claas Balers Turn 30
Claas built its first variable chamber round baler - the Variant 100 - in 1996, so 2026 marks 30 years and the fifth generation of the Variant name, recently complemented by the new Cerex Series introduced in 2025.
The set-up is ideal for seed and fertiliser application in one pass, but also lends itself to the combined application of seeds and companion crops.
As an example, during the spring the f-drill can be used as a fertiliser hopper with the Optima F or in combination with the Kultistrip strip tillage unit. When paired with a power harrow drill combination, it can be used as an additional seed hopper for sowing companion or spring crops.
In summer and autumn, the hopper can be combined with a power harrow, offering working widths from 3-6 metres, with the potential rate of material delivery to the rear from 25kg per minute to 32kg per minute.
Available in two sizes, the f-drill compact has a capacity of 1,600 litres and the f-drill maxi up to 2,200 litres. Optional specifications see the standard versions equipped with a single Eldos metering unit, while the Duo unit offers higher application rates. The Eldos units each distribute up to 400 kg/ha of one type of fertiliser or seed. The company says that high volumes are ensured by the venturi system, with no need for a pressurised system.
The delivery pipes on the new hopper are of a smaller bore than previously fitted and are built-in rigidly up to the point where they descend to the coulters.
The configuration is said to ensure that the material is carried in a faster flow of air with reduced loss of kinetic energy due to friction with the pipe wall. A modular construction featuring a steel frame and moulded plastic hopper results in an even weight distribution, while also offering the driver an unrestricted view over the entire machine setup. The wheel packer system is fitted with a lifting function that is designed to relieve front axle loading, while the self-steering packer reduces the power requirement and fuel consumption.
The f-drill can be connected to any ISObus compatible tractor for use by the tractor’s own terminal. Alternatively, it can use Kverneland’s IsoMatch Tellus Pro or Tellus GO+ terminals – both are fully ISObus compatible.
