Four-Rotor Rakes

Swadro 1400 • Swadro 1400 Plus

• Variable, up to 13.50 m (44'4") work widths
• Convenient handling from a choice of KRONE operator terminals or an existing in-cab ISOBUS terminal.
• Foldable tines (Swadro 1400) or a hydraulically lowering running gear (Swadro 1400 Plus) reduce the transport height to less than 4 m (13'2")

Swadro 1400 and 1400 Plus from KRONE have four rotors that work at variable widths between 11.00 m (36'1") and 13.50 m (44’4) coincide with work rates of up to 13 ha per hour. These machines stand out for enormous acreages, quick changeovers, rapid travel, great longevity and easy use.

The KRONE Tridem running gear: The Tridem bogies have two castering wheels clad with wide tyres running on the front and rear axle. The rear axle can take offset castering wheels in a tandem arrangement, thereby offering particularly smooth running.

Optimized driveline: Movable gearboxes mount far out on the wings to optimize the driveline. Swadro 1400 Plus features heavy-duty driveshafts and the rotors are protected by star ratchet clutches.

Massive coil springs on the Swadro 1400 Plus shift much of the weight of the jib and rotor to the main beam, preventing the rotors from sinking into wet ground and ensuring good tracking in sloping fields. Dynamic suspension is an option on the leading rotors and is useful in extremely undulating and boggy terrain where it improves contouring. The system adjusts the rotor suspension automatically and relative to the work width set on the jib, which is done by a hydraulic cylinder on the beam (right photo).

Changing work widths hydraulically: The work width on the front and rear rotors is adjusted by telescoping the arms hydraulically, thereby moving also the positions of the right-angle gearboxes which drive the front rotors. This system warrants effective overlapping of both ends of the driveshafts irrespective of the current work width.

Variable working and windrowing widths: Vary the work width easily from 11 m (36'1") to 13.50 m (44'4") and adapt to any field situation. At the same time, vary windrow widths from about 1.40 m (4'7") to 2.20 m (7'3") by adjusting the rear rotors. The leading rotors operate at higher speeds than the ones at the rear, throwing the crop wide and ahead of the rear rotors which rake it into uniform and fluffy windrows without roping.

Controlling the height of the rotors conveniently from a cab-based terminal with large display screen is standard specification on these models. This way, the operator adjusts all rotors at once or each rotor individually. Swadro 1400 Plus allows operators to set the height on one rotor and then have all remaining rotors adopt the current setting.

The Alpha control box for the Swadro 1400 gives finger-tip control of rotor height, work width and windrowing width as well as individual or sequential rotor up/down control.

The DS 500 operator terminal: The DS 500 terminal has a backlit display which shows the current settings. This terminal provides all Alpha features plus auto height control on Swadro 1400 Plus after the height was set on one rotor. An optional joystick is available to off er even more convenient operation.

CCI 1200 operator terminal: Offering a large 12inch colour touch screen, this terminal splits into three separate views, offering a customized user interface. CCI 1200 is ISOBUS compatible and therefore a universal terminal that is ready for use on other machines as well. For added operator comfort, it also has inputs for an optional joystick (WTK) with customizable controls.

The ISOBUS-compatible tractor terminal: Here is an example of an ISOBUS-compatible tractor terminal which controls all machine functions.

The automatic SectionControl feature is very useful when raking out wedges and awkward patches. Detecting raked areas and raising the rotors, this feature prevents the same patch is raked twice.

A comfortable transport height: All Swadro 1400 models have a transport height of less than 4 m (13'2”) after folding the outer tine arms. This is not necessary on the Swadro 1400 Plus The beam lowers hydraulically to bring the machine down to the statutory transport height.
