Adjustable Working Widths
You can quickly adjust the working width and window width by using a crank or a handle. In many crops, the density makes it necessary to adjust the windrow width. Working width and windrow width are easily adjusted when the rotors are in transport position. When placed in working position, the rotors extend automatically to the preset position. Whatever the setting, the rotors are always set at the lowest possible height in transport, to avoid time-consuming removal of tine arms.
The 3D suspension is enabled by a rotor arm and rotor that are linked by a double link rod. The 3D rotor articulation ensures high-quality raking because the rotors are able to follow undulating terrain smoothly and closely without damaging the crop stubble.
Hyper-Tangential Tine Arms
The hyper-tangential tine arms make windrows larger and fluffier by effectively pushing the crop towards the outside of the rotor. This windrow formation allows for easier crop pickup by the baler or forage harvester with minimum loss and there is no risk of pulling crop out of a formed windrow. Lastly, high quality raking at higher speeds is available due to a reduced distance between tine passes.
The tine angle provides clean raking and gentle handling of the crop, whether light or heavy, with minimal ground contact. The tines are made of heat-treated steel, optimizing service life and increasing resistance to wear. The “floating” attachment of the times, featuring three large-diameter coils, further reduces wear.
A bogie axle for rotor guidance is ideal for raking difficult terrain (deeper pivot tracks, uneven ground after grazing) and where higher raking speeds are desired.
