Kuhn has been experimenting with its FC13460RA trailed high-capacity mower for some time, but it is now ready for the market. We caught up with one of the first production units for an exclusive in-field look.
Weight and transport height are two very solid reasons why we have not seen wider working butterflies. Yet there is demand for machines that’ll cut more grass on each pass and make efficient use of the available horsepower. Kuhn’s latest solution for bigger mowing widths is the new FC13460RA. This semimounted machine utilises a number of proven components, as we found out.
Variable cutting widths
Kuhn’s spec sheet shows a working width of 12.40m to 13.40m when partnered with a 3.50m wide front mower conditioner. When tucked in to 12.40m, the overlap is 75cm (reducing to 25cm when full extended). It is also possible to use the 13460 with a 3.10m front mower, in which case the overlap is 55cm and 5cm respectively. And due to the massive working width, Kuhn is eyeing up farms wanting a controlled traffic system.
The pivot point of the Cat III/IV N lower link crossbar is kept back from the tractor to aid manoeuvrability. Otherwise there is only the wide angle Bondioli & Pavesi shaft, the load sensing pipes, electrics and the air brake hoses to connect. For smooth, speedy work, the tractor should produce 120l/min of oil. The mower weighs in at a substantial 8.4t, so Kuhn has opted for large 600/50 R22.5 tyres inflated up to 1.5 bar to help spread the load.
