Claas has added two mower conditioners to its triple mower range, the Disco 8400C Contour and the Disco 9100C Contour.


The arrival of these butterfly-type triple mowers means there is now a choice of five conditioner and two non-conditioner triple or butterfly models to choose from, with working widths from 8.1m to 9.1m.

Both the new models have a mounting system for the outer two rear-mounted units that is designed to position them as close as possible to the tractor to reduce axle loading.

The outer units are also centrally suspended and incorporate Claas’s Active-Float hydropneumatic suspension system. This system allows the operator to adjust the suspension pressure from the cab according to the conditions, thereby ensuring a clean cut and minimal risk of soil contamination.

The outer units also have an automatic breakback feature – when an obstruction is hit the whole mower unit swings back and lifts to avoid damage.

All three mower units use the Claas conditioner unit, which is fitted with rubber-mounted steel tines. A full-width spreader hood is also available to allow the crop to be spread across the full width of the mower.

Both mowers use the Claas P-Cut cutterbar, which is designed to give an even and clean cut. Drive to the discs is through a smooth-running, low-wear transmission using large diameter gearwheels, with an individual drive system for each cutting disc.

The cutting discs are set lower in the cutterbar for a cleaner cut and improved crop flow and are mounted in a new, high-strength sealed roller bearing assembly.
