Claas has added a new single-rotor swather to its green harvest range.

The Liner 320 completes the Claas range of compact swathers and incorporates advanced technology features found on larger rakes in the range.

The Liner 320 has a working width of 3.2m for use with smaller tractors and in awkwardly shaped fields or on difficult hillsides.

As with larger Claas rakes, the rotor drive, including the cam track, is completely sealed and continuously lubricated.

The rotor is fitted with eight tine arms, each with three 9mm diameter spring tines that are clamped in place using a cotter pin.

Working height is quickly and easily adjusted using a lockable hand crank.

The Liner 320 rake shares a lot of its features with its bigger relations.

In standard trim, the Liner 320 is carried on a single axle fitted with large 16/6.5-8 tyres, but a tandem axle is available as an option.

Each of the robust arms incorporates a defined bending point, so in the event of the arm striking a solid object, this will bend to avoid the drive system being damaged.

A U-shaped stabilising frame incorporating the three-point link points to attach the Liner 320, guarantees smooth contour following, even in difficult conditions or on hilly terrain.

Having removed some of the tine arms, the Liner 320 can be folded down to 2.25m for transport or storage and the protective covers can be easily folded out of the way for ease of access or maintenance.

Corto series

The current Corto 3200F front mower has now been joined by the new Corto 310F, which has a working width of 3.05m.

The Corto 310F features three-dimensional ground contour following, resulting in a clean cut and protection of the sward.

This system is based on an integrated lateral and longitudinal linkage geometry, which allows the mower to pivot freely for accurate ground contour following.

The Corto 310F also incorporates a simplified process for adjusting the swath discs, making it far easier and quicker to alter the swath width.

Where particularly narrow swaths are required, it is also possible to fit a second set of swath discs.

Other new features include improved crop flow through the mower and flexible rubber collision protection that prevents damage should an obstacle be hit.

All these improvements have also been incorporated into the Corto 3200F, which also features a new design and improved crop flow.

A new option available on both the Corto 3200F and 310F is the actively floating hydraulic suspension system, which was previously only available on the Disco disc mower range.

As ground conditions change, active float enables the operator to alter the ground pressure imposed by the mower by transferring the weight of the mower from the ground to the tractor while on the move.

This results in improved ground contour following and protection of the sward, as well as a reduction in soil contamination on rougher ground. Higher forward speeds are also possible and fuel consumption reduced.

A new addition to the Corto range is the 3200 Contour, which has two large and two small drums, giving it a working width of 3.05m. It replaces the current Corto 310.

The Corto 3200 contour is designed so that the main pivot point is at the centre of gravity and this, combined with the active float suspension which is standard, guarantees optimum ground contour following across all terrain.

In the event of a collision with an obstacle, the break-back protection system incorporates an angled pivot point so that the mower body is lifted up and over the obstacle.

The belt drive also acts to cushion peak loads, helping to avoid damage to the drive train.

To aid ease of use, the design of the Corto 3200 includes standard features such as double-link arm guides and kennfixx grips on the hydraulic hoses to make hitching as easy as possible.

User-friendly

For transport, the mower is carried at 120° so as to provide optimum weight distribution and enhanced visibility to the rear.

Options include hydraulic locking of the mower when in the transport position (in place of a cable) and a parking frame is also available that allows the Corto to be stored in the transport position.

Where space is tight, this frame is also available with castor rollers to enable the mower and frame to be rolled into the final storage space.

Claas has also updated the smaller Corto 190 rear drum mower, which has a working width of 1.85m.

New user-friendly features include folding protective covers on both sides, mechanical break-back protection and a parking stand.

Optional features include spring suspension to reduce wear and tear to ensure improved ground contour following, plus hydraulic headland lift for an improved lift height.
