2025 CLAAS Liner Four-Rotor Swathers 4900 Business PRO

With working widths of 30' 5" - 49' 2" (9.30 – 15.00 m), LINER four-rotor swathers form the perfect swath for the harvesting machine following behind.

Features may include:

We understand the importance of doing a first-rate job and producing top-quality forage. So we offer not just the widest tires on the market, but the largest choice of tires to boot – not just for the main chassis, but for the rotor chassis too.

What's more, CLAAS is the only manufacturer to offer the patented fully floating cardan (gimbal) suspension. A dual spring enables quick and simple equalization of the swath rotors to ensure ultra-smooth running – even at higher operating speeds.

Time is money. So we deliberately opted for a mechanical power train because it is simple, direct and efficient. The friction clutches we use provide outstanding power transmission and 'non-stop overload protection'.

In addition, the patented design with double telescopic function and C-profile makes it incredibly easy to switch rapidly between working and transport position – and the working width can be adjusted from the comfort of the cab.

When it comes to the core component of the LINER, we naturally turned to our tried-and-tested rotor drive assembly for professionals. It runs in an oil bath for continuous lubrication to ensure maximum service life.

The main frame is the primary supporting element in the four-rotor swather, like a spinal column in a human. The enormous cross-section, combined with the trapezoidal profile, is designed to absorb forces evenly. The control block, electronics module and hydraulic valves are located on the inside, where they are well protected.

If you find yourself doing a night shift, you can still keep a close eye on everything.

What's more, the machine is not just intelligently engineered – it also features a range of well-conceived solutions designed to make your job easier. For instance, all hose connections are tidily stowed in a special parking bracket. And the hoses are clearly marked to make it easy to attach them.

BUSINESS

These models are equipped with ISOBUS and numerous automation functions, designed to lighten the operator's load. A wide variety of machine parameters can be individually configured, saved and adapted to the field conditions with just one click.

TREND

If you opt for this machine, you benefit from simple, direct operation via the control units. Furthermore, this model needs only two double-acting spool valves for the front arms and main frame, as well as the telescopic arm. A single-acting control unit is additionally required to control the rear swath rotors.
