Chief among the latest forage equipment developments from Krone, including new mowers and a revamped rake, are the updates and new introductions to its round baler range.
In particular, the company has been busy updating its Comprima range, replacing the Xtreme with Plus models. Both the semi-variable chamber and variable chamber bales have seen revisions, with the combibaler getting the most attention.
While the variable chamber baler gets step-less adjustment from 1,000mm to 1,500mm, the semi variable uses a bar with pre-drilled holes to change the bale size in 50mm increments from 1,250mm to 1,500mm.
Taken from the firm’s forage wagons is its EasyFlow pickup, measuring 2,150mm wide. Helical tine arrangement and no cam track are said to ensure efficient intake of material with minimal wear. As well as swing out, pickup wheels now also castor.
A new 530mm Hardox rotor is used, with the option of 17 or 26 knives. Cut length varies between 42mm with a full set of 26 knives engaged and 128mm with half of the 17-knife set option engaged.
The XCut rotor also features a helical design, forcing material to the edges to ensure firm bale shoulders, claims the company. Knives are engaged hydraulically.
Inside the bale chamber, the company has continued to use its unique belt and slat system. This has been upgraded for increased longevity and higher bale densities.
In the fixed models, the NovoGrip belt has grown from 115mm to 147mm, while the variable belt is now 115mm instead of 90mm.
The company says the centre of the bales can be made considerably tighter with this system, when compared to a fixed chamber roller baler, as compression starts at an earlier stage. Net or film can also be used.
Drive line has been upgraded, with chains growing from 32mm (1.25in) to 38mm (1.5in). Sprockets and pulleys have also been beefed up.
Automatic lubrication for chains and bearings is now standard, with only the pto needing to be greased by hand.
Wrapping assembly has also been fettled, with a new transfer utilising gravity and a lifter in the bottom to ensure safe bale placement on the wrapper, says the manufacturer.
Wrapper arms now spin at 36rpm, completing wrapping cycles quicker.
Film can be pre-stretched to 50 or 75 per cent. A weighing system can also be added to the wrapping table on CF and CV models.
IN addition to Comprima updates, the company has taken the decision to develop its own belt baler for drier crops.
Called the VariPack, the variable chamber baler comes in two sizes, the first capable of a 1.65-metre maximum bale size and the second 1.9m. Both have a minimum size of 800mm.
Using components from its existing machines sees elements such as the cam-less EasyFlow pickup added. Helical arranged tines are positioned across the 2,150mm-wide pickups.
The integral XCut rotor is also 530mm in diameter. Up to 26 blades can be deployed for cutting crop, with the smallest chop length 42mm, or 84mm with half the blades in.
Four 275mm belts are responsible for bale formation. The company sees this machine as a high output straw and hay baler, with features such as its five-second bale ejection routine aimed at adding capacity and maximising bales per hour.
The manufacturer says durability and reducing routine maintenance was a major concern, hence the use of cam-less pickup and integrated rotor, as well as a 32mm main drive chain.
FRONT mowers without conditioners are now available with the option to spec as push or pull types.
The range includes 3.2-metre versions with or without swath forming rollers and a 3.6m version only available with the swath former. Swath rollers are spaced 1.45m apart.
The main advantage of the push type (pictured), the company says, is its compact dimensions, including reduced distance between the cutter bar and front axle, aiding road transport, as well as an all-round simpler design.
Once set up on a tractor, contour following is comparable to its pull type cousin, without the extra bulk of the suspension and lift system, says the manufacturer.
However, it adds that it is ideally a one tractor machine to reduce the amount of time needed to set cutting height accurately.
Lateral suspension is provided by two large springs, which hold the mower level when the bottom three-point linkage pins are floating in the large slot in field mode.
A telescopic top link with internal spring is also recommended for accurate ground following and suspension in the vertical plane.
However, the coup de grace with the range is the lack of an A-frame, an unnecessary complication these days, according to the company.
With so many types of A-frame available, the simplest solution, the firm says, is to standardise the range and stick with three-point linkage attachment.
FEATURING modern, sleek and curved framework, the firm’s trailed mowers are available as centre pulled, enabling the mower to be offset either side of the tractor, or as a simple side pull.
Seven variations of the range are available: a side pulled (TS) plain mower in 3.16-metre working width; the same configuration but with roller or tine conditioner; a centre pull (TC) with the same working and conditioner options; as well as a 3.6m side pull with the two conditioner options.
Mower frame geometry has also been tweaked, allowing for greater lift height and improved lateral float.
Suspension is provided by springs on the plain mower, and hydraulic and nitrogen dampers on the conditioner models, which can also be equipped with the optional cross conveyor.
The company has also launched a new style of conditioner which can be fitted to any of its CR roller conditioner models.
Designed for consistent crimping in delicate crops, such as Lucerne, the M rollers measure 250mm in diameter for improved crop flow.
REPLACING the company’s popular Swadro 1400 is the Swadro TC 1370. The new four-rotor rake features a trapeze-shaped main beam for added strength.
Hydraulic suspension is favoured over the springs of old and height is controlled electronically. This allows weight to be split between the tractor or rotors, or put solely on either.
All four rotors feature 13 arms, but the front features four double tines per arm, whereas the rear, which does more work, has five.
Each rotor now also features an overload friction clutch to protect the driveline.
At the rear, air brakes are now an option, as is the choice to fit 710mm tyres. Other options for the rotors include up to six wheels with the front and rear steering and a guide wheel mounted ahead of the rotor which helps lift it when a rise is encountered.
Working widths range from 10.8 metres to 13.7m, with swath widths of 1.4m to 2.6m. Option and control of settings is through an IsoBus terminal.
