Kuhn unveils 14.5m mower for high HP harvesters
With most forage harvester manufacturers offering machines touching 1000hp, the logistics puzzle has always been ‘dropping” grass and pulling into a swath big enough to feed the “beast”.
Both machines are said to be designed for intensive use, raking dense and heavy fodder, featuring the master drive double reduction gearbox with conical and cylindrical sprockets.
Meanwhile, aluminium alloy bearings using a guide with bronze bushings and an outward sealing ring allow a significant reduction in the weight of the machines’ moving parts.
Additionally, the design is said to extend the service life of the rotors, with the lubrication intervals pushed out to 200 hours.
A high frame ensures fast rotor lift during turnaround manoeuvres, while providing under rotor clearance from 43 to 70cm, depending on the working width setting, in order to avoid damaging previously formed windrows. The rotor attachment point is optimised to lower the rear of the rotor first, with plant cover preserved thanks to the “jet effect”.
Hydraulic adjustment of the working and windrow widths is standard, while multiple options include hydraulic adjustment of the working height, individual rotor lifting, wider transport wheels, bogie axles and a hydraulic windrow curtain.
