Krone boosts forager line-up with new models and features

Following on from the development of its ‘small’ series Big X 480 and 580 self propelled foragers, Krone has added extra models right through its range.

Currently, the line-up consists of the Big X 480 and 580, which use a 630mm wide chopping cylinder, and the larger 600, 700, 850 and 1100 which use an 800mm wide chopping cylinder.

 

For 2016, to give customers more choice, the firm has inserted three new models; the 530 and 630 to add to the smaller machines and the 770 to add to the larger machines.

 

Greater appeal

In particular, the 630 and 770 are said to be suited for contractors, offering a high degree of versatility when harvesting mixed crops.

 

In addition to extra models, the larger machines have also been refreshed and now get several features adapted from their smaller stable mates. This includes family styling, MaxFlow drum, StreamControl, drum brake, optional additive tanks and a new, larger machine terminal.

 

MaxFlow chopping cylinder

Rather than the knives being bolted on top of conventional knife holders, MaxFlow drums see the knives ‘cupped’ inside a knife holder. The main benefit from this is it allows more space under the knife to accommodate crop – twice as much as the current chopping cylinder.

 

In addition, because the knife is now held on its top-side, the knife holder and drum body are better protected. Knives can still be adjusted via a tool which allows them to be moved backwards and forwards.

 

MaxFlow drum is standard on all models and can be specified with 20 knives (5-31mm chop length), 28 knives (4-22mm) or 36 knives (3-17mm), and all versions can have half their knives removed for a longer chop length. A 40-knife version of the MaxFlow drum is not available, but a conventional version is.

 

For safety, a drum brake is now fitted which engages when the drum is switched off, or when the operator leaves the seat, and can stop the drum in 10 seconds.

StreamControl adjustable blowing

Following on from the firm’s VariStream control which sees sprung-loaded plates positioned underneath the chopping cylinder and at the back of the accelerator to absorb peaks in uneven crop flow, Krone has now made the latter adjustable from the cab.

 

Called StreamControl, it alters how much crop comes into contact with the accelerator; the more crop which comes in contact results in a more powerful blow, but results in increased fuel consumption and increased wear.

 

If crop does not need to be blown as hard, the operator can now adjust the plate so less crop is forced into the accelerator, reducing blowing force, fuel consumption and wear rates.

Cab and styling

Cab and styling

In-cab, the larger Big Xs get a new, 10inch terminal with improved symbol display and easier machine monitoring and more intuitive to use.

 

Exterior styling sees a redesigned bonnet with increased ventilation, larger mudguards at the front affording easier driver access and the ability to accommodate up to R42 tyres, and new, rear, plastic mudguards based on the design of the smaller foragers, incorporating lighting clusters.

 

For reduced maintenance, a larger lubrication reservoir is now fitted. Redesigned flat pre-cleaners for engine air intake improve rear views and are easier to maintain.

Options

As an option, a 300 litre additive tank, controlled via the terminal, can be fitted. Dosing rates can be done via litres per minute or automatically varied depending on yield.

 

Along with optional yield monitoring, moisture metering can also be done using a near infra red sensor positioned at the base of the spout. This allows for field mapping and documentation.

 

Those chopping maize will be glad to hear spout extensions are now easier to fit via the use of quick couplers. There is also a choice of square profiled ends for grass and conical ends for maize.

 

All machines are available to order now for the 2016 season.
