Here comes the BaleTrain - raking, baling in one pass
We've all heard of road trains, soul train and gravy trains, but German machinery manufacturer Krone has come up with a novel word for the agricultural sector.
Take the German manufacturer Krone: although a late starter in the market it has carved itself a useful share and a loyal following. And its new four model range is likely to add a few more followers.
The Big-X 680,780, 880 and 1180 wide-bodied machines offer 687, 775, 898 and 1156hp respectively. The three smaller models use a 16.16L Liebherr V8, while the flagship 1180 is powered by a colossal V12, 24.25L motor from the same supplier. Interestingly, this same unit powers John Deere’s flagship harvester, the 9900, that tops out at 970hp.
As you’d expect, the 1180 needs a fair bit of fuel. Its 930L main fuel tank is complemented by a secondary 170L tank with the option of a further tank of 400L, to take total capacity to 1500L.
Similarly a standard 230L additive or water tank can be optioned to work with an additional 275L unit.
Following the harvester’s chopping cylinder, the heart of the machine is an 800mm wide crop flow system. Its new OptiMaxx corn cracker system, like previous designs, uses two heavy-duty chrome plated rollers that run with a standard speed differential of 30%. Dependent on the situation it can be configured for 40% or 50% options.
The new design sees a roller tooth profile inclined by 5 degrees to create a greater shearing effect. And it can achieve better shattering of the maize kernels. Roller dimensions are now 10% wider, 7% faster and use more aggressive spring settings for a more consistent output, particularly in tough conditions.
In the smaller machines, the roller diameters are 250mm; in the OptiMaxx unit, recommended for the Big X 1180, roller diameter is increased to 305mm – claimed to be the largest in the market. This increase in diameter is said to offer 11% more surface area and 20% more rotational speed at the circumference. These combine to allow processing of up to 400 tonnes/hour or 100kg/second. Roller bearings have been upgraded, fitted with an auto-lube system, and temperature sensors to alert operators to overheating.
Up front, the chopping cylinder has automatic shear bar setting utilising knock sensors, although manual setting is still included for sceptics of such witchcraft.
A further option is the VariLoc system that allows a quick shift from 1250 to 800 rpm cylinder speeds or vice versa. This is said to be useful for busy operators who might need to shift from forage to AD production during the same day, which only takes a few minutes.
Also aimed at maximising daily outputs is the option of EasyLoad, a 3-D image-based system for automated spout control, using a front-to-rear or rear-to-front filling sequence.
Likewise, a tie up with Italian weighing specialist Diamamica Generale allows customers to option machines with the AgriNIR, near infra-red sensor to record crop characteristics such as yield, dry matter, crude protein, crude ash and fat content, for future ration formulation and record keeping.
A big year
Krone's harvesting division achieved a turnover of €618 million for the 2017 market year, a rise of 7%, and an increased output of 25,000 machines.
Total production exceeded 10,000 mower units, 1000 large square balers and 450 self-propelled machines in its Big-M and Big-X ranges.
Commenting on the global market for self-propelled forage harvesters, Krone estimates the total is 2800-3000 machines annually.
Meanwhile, at home the company claims to have sold 25% of the 500-520 machines delivered during the year.
About 70% of its production is exported, but its home market of Germany remains number-one, achieving 29% of turnover and a claim of 24% market share for all grassland equipment.
