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 rotors can be lifted out independently. This is standard specification on the TC 930 and TC 1000 and an option on all other Swadro TC models. This feature brings great advantages in wedges, along boundaries and in low-yielding crops.
Swadro TC 640 and TC 760 come with a standard mechanical working width control. The arms extend and retract as the operator turns a crank.
All Swadro TC models (option on TC 640 and 760) offer standard hydraulic working width adjustment. The operator can clearly read the selected work width on a large scale from the seat.
Swadro TC 680 and 760 can be equipped with a new development from KRONE – a hydraulic rotor with 6 tines that disturb and aerate dry and light material which placed in the middle of the rake and between the rotors. The disturber promotes uniform wilting and ultimately the quality of hay and leafy forage such as lucerne.
Swadro TC and TC Plus are attached to the two-point headstock by a ball bearing joint and a rod-steered undercarriage with articulated steering. This makes these rakes particularly nimble – a boon in awkward areas where no crop is left behind and shunting is eliminated. The machine simply goes into every corner of the field without manoeuvring. The articulated steering is an option on the TC 640.
Great road stability and exceptional castering are the stand-out features of the chassis that is approved to 40 km/h (25 mph). Quick changeovers: bring drown the transport height to less than 4 m (13’2″), fold up the rotors without removing any tine arms (except on TC 1000) or guards first, and retract the telescoping arms to reduce the machine width.
