The PowerSplit feature matches power to crop yield and has two operating modes Eco-Power 460hp and X-Power 596 hp . There are new 710 / 70 R 42 front tyres and a choice of rear tyres fitted to the wishbone suspended axle . The cab features a large touch screen terminal and Krone joystick for

easy and comfortable operation .

A new MaxFlow chopping drum with a choice of 20 , 28 or 36 knives provides a chop length ranging from 3mm to 31mm . The drum has twice the crop carrying capacity giving it a significant efficiency boost . VariQuick allows the corn conditioner to be engaged and disengaged in a matter of minutes .

BiG Pack HDP II is a new generation high-capacity square baler that delivers up to 50 % more bales than the 1290 HDP baler while bale density has been increased by up to 10 % without compromising forward speed . Its higher performance requires design upgrades , from the pick-up all the way down to the eight double knotters .

The flywheel now weighs 608kg and is backed up by an intermediate gearbox that increases its speed to 1,180rpm . The main gearbox is able to handle a power flow of up to 1,230KW ( 1,680hp ). The new Big Pack also features the Active Pickup , the crop press roller and the mechanical feed roller as standard specification . The pick-up also handles extremely wide swaths and short and brittle crops .

Rotor cutter diameter has been increased by 30 % to 720mm . Operators can select 26 or 13 knives quickly and without the need of tools . The cutting system is driven by a Powerband and the rotor cutter shuts off automatically if either the belt slip is excessive or the packer is blocked . At baler start , a slight delay in the pick-up avoids load peaks .

The three packer arms on the Variable Filling System ( VFS ) has been reinforced , and its feeder

arm now receives larger cam rolls , increasing the capacity of the feed chamber . Updated packer elements on the Big Pack HDP II improve the crop flow and optimizes the baler ' s stability .

Six pressure rams operate the HDP II chamber doors , the top door being operated by two 140mm rams and each of the two side doors by two 110mm rams .

The unique double eight knotter uses 20 % less space than existing knotters and can tie bales of up to 10 % higher density without requiring the baler to travel at lower speeds .

A high-capacity mechanical knotter fan backs up the established pneumatic system by directing a continuous flow of air to the knotters to continuously remove any debris .

The eight double knotters are supplied with 54 balls of twine , with an option for two further compartments , each storing six balls .

A bale weighing system is integrated in the bale ramp with an accuracy of down to 2 %. Overload protection is provided by clutches rather than shear bolts . The entire driveline as well as the chassis has been upgraded to match the machine ' s huge capacities and loads .
