EasyFlow – more efficient and more effective

Picking up the crop at a width of 1,900 mm (DIN 1120) and operating at a higher speed, the camless EasyFlow pick-up comes into its own in challenging conditions. Wide swaths, heavy drop and high workrates – here, EasyFlow is simply the best.

Cost effective and powerful

EasyFlow is a camless pick-up that delivers obvious benefits. Using fewer moving parts than systems with cam track, this system is simpler by design and is much quieter running, which results in less wear and therefore less maintenance and fewer costs. Operating at a 30 % higher speed, EasyFlow is even more effective and powerful now.

No cam – the better way

This pick-up stands out for the special design of its scrapers, which allow the tines to retract and ensure a smooth and consistent flow of material into the machine.

Full adaptation

The pick-up pivots in a linkage system pushes the unit over the ground. Pivoting freely, the unit adapts to ground flow both axially and transversely, ensuring a clean rake and an impeccable surface.

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, the system avoids scuffing and offers best protection of the turf.

Guide wheels at the rear

Optional guide wheels at the rear of the pick-up enhance the overall running and ensure all material is picked up from soft and wet ground. Not running in the tractor tracts, these height-adjustable wheels ensure the depth of the pick-up tines is maintained at all times.

Plenty of ground clearance

The articulated drawbar with double-acting ram is standard specification and provides for a generous ground clearance of up to 75 cm (2'5.5") – enough to roll on clamps without pushing up material.

Cross conveyor belt

The hydraulic cross conveyor discharges the feed to the left and right and easily stores underneath the machine.

Loadsensing

The Comfort level hydraulic control system is compatible with load sensing systems. Load sensing systems control the oil flow and the oil only on demand and thereby reduce the strain on the tractor.

Bespoke tyres

You select the tyres that are approved for this axle and that suit your application best. Wide tyres give easier pulling on soft ground and reduce the risk of compaction.

Suspended drawbar

The optional drawbar suspension system uses nitrogen tanks on the rams to absorb all shock loadings and provide a superior operator comfort.

More output from less horsepower

Buying a KRONE MX forage wagon means buying into experience and expertise. Innovations such as the camless EasyFlow pick-up system, the massive cut-and-feed rotor, the knife bank that swings out to the side, and the chain-and-slat floor that slopes at the front, all combine to implement higher throughputs, lower power inputs, more operator comfort, and less wear and maintenance.

Roller crop guard

The unit eliminates the risk of pushing up crop in uneven swaths and allows the machine to operate at maximum pick-up and output levels while the crop flows smoothly and consistently through the machine.

The better way of forage harvesting

The 880 mm (2'11") by 1,640 mm (5'5") MX rotor with eight helix rows of tines cuts and feeds the crop with extreme power. The tines feature extra wide plates made from Hardox steel to provide gentle crop treatment, enhance the quality of cuts, and use less power.

Loading, feeding, cutting is better now

The MX cut-and-feed rotor combines the benefits of a traditional rotor feeder with those of a swing arm feeder. It is powerful and soft on the crop, as well as low-maintenance and modest in its power requirement. Depending on the model and conditions, the MX self-loading/self-unloading forage wagons can be operated by tractors with 120 hp or more.

Extra strong driveline

The drive power to the rotor flows through oil-immersed spur gears. The driveline is maintenance-free, copes with the highest loads, and warrants dependable operation during the peak season.

Hardox for longevity

The cut-and-feed unit is exposed to the highest strains; therefore, we made its tine plates and scrapers from Hardox steel to reduce wear and increase the unit’s service life.

The crop is pulled over the blades

The knives cut down their full lengths, allowing the system to run easier and quieter. The wavy blades maintain their sharpness over extended periods.

Cutting like scissors

This technique prevents the stems from slipping through the narrow clearance between the wide tine plates and the knives, which eliminates the risk of mushing and guarantees perfect cuts.

Finest quality of cut!

Cutting like scissors... The secret behind this system, which cuts the crop like scissors, lies in the extremely narrow gaps between the wide tine plates and the spring-loaded knives. As many as 41 knives are available to produce perfect cuts. The central knife selection system operates the knives in sets of 23 or 46 for quick chop length adjustment.

Automatic knife selection system

The central knife selection system makes it easy for the operator to set the desired chop length. MX operators can select sets of 20, 21, or 41 knives, setting the nominal chop lengths to 90 mm or 45 mm; 0 means the system will not chop the crop.

Cab based control

The knife bank is lowered hydraulically when a blockage occurs. Once the blockage is removed, the knife bank swings back into position, and work is resumed.

Individual knife protection

Each knife benefits from its own spring-loaded protection, retracting and swinging back automatically after the object has passed.

From the ground

These extra controls raise and lower the knife bank conveniently from the ground for easy maintenance and knife changes. The controls are available on machines that feature the Comfort on-board control system.

Straightforward and convenient

It’s easy: Lower the knife bank and swing it out to the left, then remove all knives from here – a time and cost-saving system.

How you do it:

Lower the entire knife bank hydraulically, move the knives to position 0, and unlock them. Then release the bank from a lever on the left machine side and swing out the unit.

Keep it all in

An optional plate is available to guard the rotor as the machine is loaded with maize or grass from the forage harvester, ensuring that not a single stalk or stem is lost through the intake area.

Mx 320 gd, mx 350 gd

These versatile rotor wagons with solid steel sides and extensions are equipped with up to three discharge rollers, which unload the material in uniform mats to reduce the workload on the clamp, providing the best conditions for high-quality hay silage.

Floor with four chains

Two chain-and-slat floors ensure MX unloads the material smoothly and fast. The four short-linked chains are high-tensile and long-serving.

Advancing to success

Our MX range meets the needs of customers who also use their forage wagons in large-scale and contracting applications. The sloping chain-and-slat floor is an achievement that provides efficiency and smooth-running at the same time.

Powerful driveline

The hydraulic chain motor varies the floor’s advance speed infinitely variably. The self-unloading models feature an additional reversing mechanism that moves the material away from the discharge rollers to solve a malfunction, for example.

Powered from either end

The split chain-and-slat floor with motors on either end is an option on MX 320 and standard specification on MX 350. Operators can double the floor’s advance speed from a spool.

Powerful chain-and-slat floor

The chain-and-slat floor slopes at the front and thus reduces the length of the passageway and the power required to feed the material into the load area, translating into a faster and gentler crop feed. The advantage is maximized efficiency at minimized fuel consumption.

Taking more in

Automatic loading system with fill level and pre-compression sensors. Automatic floor shut-off protects the tailboard from damage, ensures smooth discharge roller start-offs, and warrants loading to full capacity.

It’s safe, too

This sensor switch on the MX GL tailboard triggers the shut-off mechanism of the chain-and-slat floor. The floor automatically stops advancing to protect the tailboard from damage.

The chain-and-slat floor stops automatically

When the machine is filled to capacity and material is pushing the bottom rotor to the rear, the motion detector stops the chains and the discharge rotors start off smoothly.

Packing more in

The MX self-loading/unloading forage wagons are designed to maximize your outputs. The optional automatic loading system uses an extra pre-compression sensor that helps pack in as much material as possible. MX means maximum loading and minimum transport costs.

Boosting capacity

The automatic loading system is an option on our MX models with steel extensions and Comfort electronic box. To achieve higher filling levels and a higher pre-compression, the system comprises a pre-compression sensor that sits down on the headboard and a number of filling level detectors at the top. Only after both sensor systems are activated, will the chain-and-slat floor start advancing and moving material to the rear. The system ensures a consistent feed of material to the rear and fills to capacity; in addition, it relieves the operator from the strain of watching the loading process and eliminates the risk of air pockets forming inside the crop.

Versatile

MX has a very robust body. Lacking top hoops and ropes, they make perfect trailers to run in the maize harvest chain.

Harvesting without losses

High efficiency and versatile application, the MX 320 GL and 350 GL forage wagons with solid steel extensions and 32 m³ and 35 m³ load areas are tailored to large-scale operations and contracting businesses. These machines are designed to deliver highest levels of efficiency and profitability.

Pump it all out

Featuring a wide opening tailboard, two chain-and-slat floors and smooth, vertical sides, the MX GL model effectively and smoothly pumps out huge masses of forage.

Operation

The machine is controlled via the Comfort on-board electronic box – either from the tractor seat or from the control panel on the machine next to the belt.

Reaping success

The first step in making quality silage is spreading the material in uniform mats on the clamp. The MX models with steel sides and up to three massive rear rotors unload the material layer by layer and across the full length of the heap, maximizing your clamping efficiency.

The heavy-duty driveline

Strong chains and spring-loaded chain tensioners transfer the drive power efficiently and without losses to the rollers. A motion detector on the bottom roller shuts off the floor to ensure smooth unloading.

The direct driveline

The direct driveline warrants dependable unloading. The main driveshaft has an integral overload clutch that protects the rotors and speeds up the unloading process, saving time and boosting the machine’s efficiency.

Three rotors for triple power

Specify your forage wagon with an optional third roller and you will spread the material in even more uniform mats. Studded with V-tines, the rotors spread the crop across the full machine width, with the bottom rotor spinning faster than the top rotors to cut down on unloading time.

Medium on-board control box

The Medium level on-board electronic system including Alpha operator terminal is base specification on all MX self-loading/unloading forage wagons.

Comfort on-board box

The Comfort electronic system is ISOBUS compatible and is required to operate optional components like the automatic loading / unloading system.

The Alpha terminal

The Alpha operator terminal on the MX self-loading/unloading models controls the pick-up, the articulated drawbar, the chain-and-slat floor, the knives, the tailboard and the work lights. A bar graph shows the floor’s advance speed on the self-unloading models. LEDs indicate all functions including the optional locking function on the steered axle.

The Gamma terminal

This terminal offers operators full fingertip control of all loading and unloading operations. Here you retrieve the number of hauls and operating hours as well as diagnose potential malfunctions. The backlit digital display screen provides an excellent overview of all machine functions. In addition, the Gamma terminal controls the automatic loading and unloading system, automatic locking of the steered axle, the cross conveyor belt, the silage additive feed system and fast floor advance. You can operate the knife bank also from the ground on two controls next to the unit.

Dependable in the heat of harvest

MX 350 GL is a heavy-duty machine with an up to 24-ton weight rating. It delivers efficiency, cutting quality and dependability – all key criteria for effective silage harvesting.

Control it from the cab

The steel tailboard is operated by two single-acting rams on the sides – and is locked and unlocked automatically.

On the road to success!

Heavy-duty axles will a requirement you can’t do without, if you are looking for high capacities and swift travel between the field and clamp. Our suspended tandem axles with axial draft arms and our tandem axles with hydraulic auto-levelling respond to these demands and are absolutely heavy-duty and offer superior rides.

Draft arm guidance

This spring-loaded assembly with balancing arm and parabolic springs features extra draft arms between the undercarriage and the axles to give maximum stability and easy pulling. The pulling effect provided by these beefy arms is the ideal design for smooth running on clamps and travelling around bends, taking strain off the parabolic springs so these serve exclusively for suspension.

Hydraulic control

Large wheels and high sides pose high demands on the running gear. The caster steered tandem axle offers hydraulic levelling to cater for all requirements and needs. The running gear offers maximum stability when travelling at speed, around bends and on slopes, providing absolutely convenient and safe rides.

The system

The oil flows from the cylinder on the front wheel to the cylinder on the rear wheel on the same side and vice versa to compensate for uneven ground. The concept of using two separate and enclosed circuits inside one axle assembly eliminates the risk of rolling and maintains the body level at all times.
