ZX 470 GL Krone ZX 470 GL Specifications & Technical Data (2018—2022)

Flap discs

The 24 flap discs have generously overlapping flaps. Warranting superior performance and longevity, they give a 'cold' grind that prevents the blades from annealing.

Operation

Operator comfort is essential. Our shockproof operator terminals are compact, clear-cut and easy to operate. They feature backlit buttons to reduce operator fatigue during those long shifts well into the night. The CCI terminal is a universal operator control unit, which is compatible with a wide variety of ISOBUS implements from many manufacturers.

Delta terminal

The ISOBUS-compatible Delta terminal offers operators full fingertip control of all loading and unloading operations. Here you retrieve the number of hauls and operating hours and pinpoint potential malfunctions. You can also control the LED work lights, the crop covers, and the silage additive system. The backlit digital display screen provides an excellent overview of all machine functions. In addition, you control the auto loading and unloading system, which automatically locks the steered axle, the electric forced steering system, the automatic drawbar, and the blade sharpener. In addition to the fingertip control option, you can also operate the blade cassette from the ground on two controls by the side of the bank.

CCI 1200 terminal

The CCI 1200 operator terminal with 12" touchscreen offers the same features as the Delta terminal. Additionally, it allows operators to split the screen into two views, for example, to see all machine control elements in one view and the camera footage in the other. Also, an additional AUX joystick enhances operator comfort even further.

Loading and unloading rates

Loading and unloading rates are important parameters in viable farming and contracting. The pivoting headboard boosts the machine’s loading capacity by up to 4.5 m³, compresses the material to needs and helps empty the machine faster and effectively.

In loading position

The movable headboard is in mid position when the forage wagon is loading. This position is stored to the control system. It is easy to adapt the board to suit varying harvest conditions.

Plus 4.5 m³

When the sensor detects the machine is filled to capacity, the headboard moves automatically towards the tractor expanding the capacity by 4.5 m³ without extending the machine length. So ZX is not compromised in its compact build and agility.

As forage transport wagon

When the machine is used to haul chopped forage, the headboard moves fore into its end position, increasing the loading volume and intake area.

Boosting unloading rates

The headboard pivots to the rear so the wall of forage topples over, ensuring the machine is emptied fast and effectively. All unloading sequences run fully automatically.

The load area

It takes high-end engineering that withstands the permanent exposure to huge masses of material and fast unloading processes. Two chain-and-slat floors, i.e. four flat link chains and two motors and a conical design that tapers to the rear will always deliver. A load sensor and a volume sensor on the headboard trigger the signal for the chain-and-slat floor to start moving when the filling level and density of the crop is right, ensuring the machine is utilized to potential and reducing operator stress.

Double chain-and-slat floor

The use of two chain-and-slat floors doubles the machine's unloading efficiency. Each of the four flat-link chains is tensioned individually and mechanically. The box section chain slats offer good grip and a positive feed.

Powered from either side

Each chain-and-slat benefits from its separate drive assembly. The gearboxes and hydromotors are journalled inside the frame without any strain. The operator can double the floor’s advance speed via a spool. Everything else is carried out automatically by the fast mode feature.

Flat link chains

The four flat link chains feature massive joints and are extremely hard-wearing and high-tensile. The wide chain links and sprocket teeth translate into less wear and a powerful advance.

The powerful chain-and-slat floor

The chain-and-slat floor slopes at the front, which increases the capacity and reduces the length of the feeding passage for a faster and gentler crop feed and a significantly reduced power input. This ensures maximum efficiency and fuel economy.

Powerful auto-loading

A strain gauge measures the load down on the headboard. When the gauge detects the load and the crop density inside the wagon has reached the default limit, the chain-and-slat floor starts moving automatically, adapting its advance speed to the strain measured by the sensor. A truly impressive system that leads to uniform fills, full utilization, and reduced fuel consumption.

Making the most of machine capacity

The volume sensor on the sensor flap at the top of the headboard senses the filling level. When the hatch at the top of headboard is opened longer than for a preset time, the system triggers the chain-and-slat floor which starts moving. PowerLoad combines the two systems. The benefit is reduced operator fatigue and full use of the machine’s capacity.

It's safe, too

After the pick-up has filled the body to capacity a sensor switch on the tailboard stops the floor and tilts the headboard towards the tractor.

The KRONE EasyFlow pick-up

The camless and hydraulic EasyFlow pick-up with tines arranged in a helix meets the most exacting demands. Absolutely maintenance-free and a benchmarker in performance, this pick-up offers an even larger work width now that its hydraulic drive has been integrated in the rotor. As a result, an increased pick-up width helps collect even more material at an optimum ground speed, maximizing the overall intake capacity.

Camless is better

This camless pick-up stands out for the scrapers and their special design, that ensure a continuous and smooth crop flow as the tines retract.

EasyFlow – more efficient and more effective

Working at a width of 2.12 mm (DIN 11220), the wide and camless pick-up with helical tines is powered by its own separate hydro motor for dependable performance also in challenging conditions. Even awkwardly shaped swaths are gathered with precision and in a uniform flow. The height is adjusted easily to suit the current crop, the swath volume and ground speed.

Hydraulic drive

The integral hydro motor offers a number of advantages: It frees space on the pick-up ends for a wider work width Maintenance-free The absence of sprockets on the sides translates into a larger pivoting range Manual or automatic ISOBUS speed adjustment to the current ground speed and prevailing conditions

Excellent tracking

The pneumatic guide wheels on either side of the pick-up offer height control for full adaptation to any ground contours. Tracking excellently behind the tractor during headland turns, these wheels avoid scuffing and offer best protection of the sward.

Large pivoting range

The laterally pivoting pick-up follows ground contours both axially and transversely and benefits from more generous travel now – courtesy of the integral hydro motor that replaces an external sprocket. The result is a clean rake and nothing is left behind.

Lifting out higher

In undulating terrain, the pick-up oscillates through a constant range around the core of the cut-and-feed rotor, maintaining an optimum flow of material into the machine no matter how difficult the conditions. Aligned with the core of the rotor, the pick-up can be lifted out high on the headland.

Auto articulated drawbar

The articulated drawbar with double-acting ram is standard specification and provides a generous ground clearance of up to 75 cm – enough to roll on clamps no problem. The new automatic articulated drawbar offers a better ground clearance for headland turns. One headland and one road position can be programmed to the control unit.

Guide wheels at the rear

Optional guide wheels at the back of the pick-up ensure reliable performance in soft and wet ground. Height-adjustable, these wheels do not run in the tractor wheelmarks, preventing the pick-up from scratching the ground.

Gentle on the soil

A nitrogen damper provides electro-hydraulic suspension for the pick-up for even better soil protection. The system allows operators to set the suspension pressure from the cab and on the move.

Powerful

The robust headboard is operated by hydraulic rams on either side. Its movement is controlled either manually or automatically. The slotted design provides an excellent view of the load area.

Perfect for first passes

The headboard tilts toward the tractor and the articulated drawbar lowers – an ideal scenario for the forager to fill the wagon following behind, eliminating any risk of crop loss and providing optimum fills.

Smooth emptying

The conical design offers the advantage of providing a wider outlet area for a smoother material flow. Also, all obstacles in the material flow have been eliminated ensuring nothing is left behind.

Automatic locking and unlocking

The tailgate is opened and closed by hydraulic rams on either side. The board is locked and unlocked automatically – very convenient.

Very adaptable

The axles provide for generous travel, distributing the load uniformly to the rear and front wheels at all times. The design provides for excellent climbing and unloading on high and steep clamps.

Full flotation

Each axle benefits from individual suspension and hence offers huge travel. As a result, each wheel puts the same pressure to the ground no matter how undulating the terrain.

Convenient attachment

The operator can also control the articulated drawbar from these buttons on the front of the machine. This way, he monitors the hitching process.

A unique pivoting system

Arranged in a W, the tines warrant a consistent crop flow and an equally consistent and full-width supply of the material to the rotor cutter, boosting throughputs and machine fills.

Crop press roller

This standard-fit roller maximizes the machine’s pick-up capacity and warrants a continuous flow of the crop into the machine. The roller can be set to various heights to match the swath size and ground speed perfectly.

The KRONE cut-and-feed rotor

The cut-and-feed rotor is powered by a 6-groove poly V-belt and planetary gears – a driveline concept that caters for the enormous horsepower of today's high-end tractors. Integrating the gearbox inside the rotor frees space to extend the rotor so work rates and throughputs can increase – a unique design that offers superb responsiveness in peak loads.

A KRONE exclusive – the Powerbelt

The unique KRONE Powerbelt drive concept in conjunction with a planetary gearbox inside the cut-and-feed rotor reduces the input speed for the rotor. The compact design of the assembly allows us to maximize the length of the rotor and hence the width of the crop flow. The KRONE Powerbelt offers an exceptionally long service life and extremely quiet running. Transmitting up to 400hp is no challenge for the extra wide belt. A cam clutch inside the tractor driveshaft protects the entire driveline from overloads of up to 2,800 Nm. But the highlight of this system is that the KRONE Powerbelt simply absorbs the peak loads caused by lumpy swaths. Maximum throughput in literally all conditions – this landmark feature makes the KRONE ZX the world’s most powerful forage wagon.

Higher outputs, better cuts

Powered by a poly V-belt, the 88 cm diameter and 191 cm wide feed rotor is extremely powerful. It features eight rows of tines in a helical arrangement. The tines have wider steel plates that treat the crop more gently for enhanced cutting quality. The feed plates are made from extra hard Hardox steel for enhanced wear resistance and extended service life at reduced costs.

Clever design

The two-speed integral planetary gearbox reduces the speed to optimize the circumferential speed of the cut-and-feed rotor. This in turn makes for a wider stream of crop that is fed into the machine.

The KRONE cutting system

Cutting like a scissor – the secret of this system lies in the extremely narrow gap between the wide tine plates and the blades. 48 blades are available to give perfect cuts. The central blade selection system quickly selects the desired number of blades and hence the length of cut.

The material is pulled over the blades

Cutting with their full edges, these blades lead to smoother and quieter running. The wavy blades maintain their sharpness over extended periods of time.

Controlled from the cab

The blade cassette lowers hydraulically to remove a blockage. After the blockage is removed, the blade cassette swings back into position and work is resumed.

Individual blade protection

Equipped with individual spring protection, each blade retracts and swings back automatically once the object has passed. The tripping force is set variably from the cab and can be adjusted to special conditions.

Central blade group control system

The central blade selection system makes it easy for the operator to set the desired chop length. ZX operators select the blades in sets of 24 or 48 which provide nominal chop lengths of 74 mm or 37 mm. '0' blades means the material is not cut.

Quick-change blades

You change the blades without tools and without leaning over the blade cassette which is now alongside the machine. Lower the blade cassette, swing it out to the side and remove the blades without tools – a time and cost saving system.

How you do it

Lower the entire blade cassette hydraulically, retract all blades to position 0 and unlock them. Then operate a lever on the left machine side to unlock the bar and swing it out (pic. 1). You can now remove all blades easily and conveniently (pic. 2). The blade cassette swings back in place and locks home automatically on its right end (pic. 3).

From the cab

Operated hydraulically, the blade cassette lowers deep for an effective removal of blockages and swings out to the side for convenient blade replacement.

Convenient for operators

These controls allow operators to conveniently raise and lower the blade cassette from the ground – for easy maintenance and blade changes.

Blade grinding interval

They can set the blade grinding interval on the terminal to adapt the intensity to the actual level of wear.

A KRONE exclusive!

This optional and fully automatic sharpener consists of a hydraulic shaft with grinding discs that slide to the side. Sharpening of all 48 blades is triggered and carried out automatically – simply by a press of a button.

Consistent sharpness

Each disc is pressed on to the blade by a bevel spring, a design that leads to a high-quality and consistent cut of all blades whilst minimizing the material that is removed from each blade. The system warrants consistently sharp blades even when these show different degrees of wear.

Sharp blades in only 4 minutes

A complete grinding cycle on all 48 blades including moving the blade cassette out and back in takes only four minutes depending on the number of cycles entered to the terminal. With the blade cassette out and alongside the machine, the operator can watch the grinding process and conveniently check on the result.

Automatic and safe

Simply swing out the blade cassette, fold up the grinding shaft, couple two oil hoses and connect an electric lead. Then press an external control to start grinding hydraulically and watch how the shaft moves automatically up and down and to the sides, completing the job without any interference from the operator. The grinding is carried out with the blade cassette out and alongside the machine so you can easily watch the process.

No losses

You can cover the cut-and-feed rotor with a plate to protect it from ingress of chopped maize when serving the forage harvester.

Smooth operation

The floor slopes 35 cm towards the cut-and-feed rotor – for increased capacity and a smoother material flow into the machine.

The tandem axle

The caster and force-steered tandem axle offers hydraulic levelling to cater for all requirements and needs. Each assembly offers maximum roll stability when managing bends at speed. More than that, they provide great stability on the slope. These axles offer maximum safety and operator comfort.

Maximum stability

To compensate for undulating ground, the oil flows from the cylinder on the front wheel to the cylinder on the rear wheel on the same side of the machine and vice versa. Using two separate circuits inside one axle assembly eliminates the risk of rolling and maintains the body level at all times.

Gentle on the sward

The steered axles are standard specification. Tracking excellently in headland turns and curved lines, these wheels eliminate the risk of scuffing, protect the sward and take off stress from the running gear.

Superior road stability

A separate oil circuit on either machine side and equal oil pressures on either side of a ZX tandem or tridem axle assembly translate into greater road stability and reduce the risk of roll when working on slopes or managing tight turns.

Up to large 30.5" wheels

Tyres are offered with a range of different treads and carcasses to provide the perfect outfit for every situation. The ZX 560 models with tridem axle can be ordered with 30.5" wheels for an increased footprint and reduced rolling resistance, protecting the sward and saving fuel.

Steered wheels

A steered front or rear axle ensures excellent tracking in every curve protecting the sward and minimizing drawbar power.

Lifting axle

The front axle can be raised by pressing a button on the operator terminal. This lift axle is a standard feature that reduces tyre wear and fuel costs in empty hauls.

Forced steering

Forced-steer wheels protect the sward and the tyres as the machine is making the turn, reducing the load on the tandem or tridem axle and resulting in easier pulling. The electronic system allows the operator to interfere with the shunting or countersteer manually on the slope or on the clamp.

Cardanic rotor suspension

The tandem and tridem axles are steered by a rod that connects to the standard hitch ball and operates the master cylinder.

Electronic forced steering

An electronically controlled forced-steer system controls the axle via the tractor's hitch ball, a steering rod and a sensor that senses the wagon's current steering angle relative to the tractor and sends the information to the axle steering system via the steering computer. This steering version uses a very compact linkage system which provides better agility than the hydraulic system.

Beware of the edge

You know it too well – the machine is at risk of slipping off the clamp whilst rolling too closely along the edge. In this situation, the electro-hydraulic forced steering system allows the rear wheels on a tandem assembly (or the front and rear wheels on the tridem axle) to steer away from the edge.

Steering uphill

The electro-hydraulic forced steering system allows operators to countersteer in situations where the wagon is at risk of drifting downhill when travelling at right angles to the slope. The system steers the leading and rear axles on a tridem assembly.

Tractor attachment

Increased gross weights have made bottom-hitching the most popular type tractor attachment, because it transfers more load to the tractor’s front axle and gives the four-wheel drive system more grunt.

Suspended drawbar

The drawbar suspension system uses nitrogen tanks on the rams to absorb all shock loadings for superior operator comfort.

Ball hitch 80

This hitch ball offers maximum operator comfort and minimizes wear on your equipment as the combination runs smoothly without jolting or experiencing shockloads. Forced-steering systems require ball hitch attachment.

Optional weighing system

The electronic weighing system uses sensor pins inside the drawbar and on the tandem/tridem axle with hydraulic levelling. The system determines the weight of the load by computing the difference between the gross weight and the weight of the material left on the machine after unloading is completed.
