Permanently lubricated and maintenance-free. The enclosed bevel gearboxes and the tine arm rollers are permanently lubricated for optimum care and attention. So, operators need not bother to lube a single component on the rotor.
Boosting the productivity of the entire harvest chain is no problem for KRONE Swadro. The steep cam track is made from hard-wearing materials and provides precision guidance for the tines. A small track diameter in combination with massive cams make for quiet running, reduce wear and lead to well-shaped swaths. DuraMax cam track – maximum efficiency and maintenance-free components. Swadro is fun to use.
Great flexibility and cleanest rakes
The cardanic rotor suspension: The rotors pivot in and across the direction of travel to give optimum adaptation to undulating ground. A cardanic joint on the arm with two elongated holes prevents the tines from being pressed into the ground or from being left suspended in the air, thereby avoiding crop contamination as well as throwing the grass about.
The central suspension: The rotors suspend centrally across the direction of travel which allows them to produce consistent and high-quality windrows. The special suspension ensures they always stay level as they lift and lower on the headland. In addition, the machine’s weight is distributed uniformly on all wheels of the running gear as it travels down the field.
The KRONE Jet Effect prevents the tines from damaging the sward on the headland and ensures the crop stays clean. As the bogies are lowered into work, the rear wheels touch down first before the leading wheels follow. Vice versa, as the rotors lift out it is the leading wheels that lift out first and the rear wheels that follow. This is identical with the take-off and touch-down phases observed with airplanes.
Great stability and excellent tracking
Wide track width and quiet running: It is the extra wide tracking width of the running gear that absorbs the forces that are generated by the rotors and keeps them level and stable in undulating terrain.
Stable running and tidy windrowing
Tine arms and tines: The tine arms are thick-walled and large in diameter. 10.5 mm (0.4″) double tines that wind around the arms in three massive spring coils offering outstanding flexibility and longevity. Each tine arm carries four double tines.
Each tine arm is easily removed: Simply undo two bolts to remove the entire arm complete with bearing and roller.
Sturdy foldback mechanism: Gap-free and hard-wearing functionality comes from a holder that is made from hardened steel and has a pivoting joint that is loaded by a Belleville spring on the models with multiple rotors.
Clean windrows, better feed
Setting the tines to an optimum position: The special Lift tines perform better, because their ends maintain a steep angle even in heavy crop and lift it more easily, which leads to more uniform windrows. As a result, the machine can work at a faster pace and still deliver consistently well shaped windrows.
No crop contamination: Thanks to their excellent performance, the Lift tines can work at a greater ground clearance than traditional tines. And thus reduce the risk of crop contamination as well as tine wear.
The flexible side delivery rake
Safe attachment: The drawbar – floating drawbar or linkage drawbar – is height-adjustable and the hitch ring is controlled by a parallel linkage. The hydraulic ram on the drawbar maintains the leading rotor parallel to the ground as it is lifted and lowered.
No need to leave the cab: The rear rotor features hydraulic crop deflector control for convenient adjustment from the tractor seat. The curtain retracts hydraulically into transport position.
Tandem axles: A wide wheelbase with 18″ wheels provides excellent contouring. The leading wheels run far on the outside to provide optimum stability in sloping terrain. The working height is adjusted via these pin setting systems.
