• The new tapered feed channel encourages the crop to flow from the pick-up and then move towards the rotor and into the bale chamber, maximising throughput.

• McHale have also moved the lateral feed augers forward and their ends are angled towards the rotor for improved crop flow.

• These changes combined offer a massive reduction in the potential for blockages to occur and in turn, increase output for the operator. 

• To reduce maintenance, all Profi-Flo pick-ups are fitted with a heavier driveline which reduces chain load and increases chain life.

Profi-Flo Cam Pick-Up

As standard, a cam operated 2.1m high-intake galvanised pick-up ensures excellent ground cleaning in all types of crop. The cam pick-up runs on a cam track that is fitted with double raced cam bearings to stand up to the most testing of conditions.

All cam pick-ups across the McHale Fusion 4 range are fitted with 5 tine bars for excellent ground cleaning, while new side bands ensure a continuous delivery of crop to the bale chamber.

A side inspection port allows the operator to quickly check and change the cam bearings if needed.

Profi-Flo Camless Pick-Up

A 2.1 m camless pick-up is available as an option on all machines in the Fusion 4 range. The camless pick-up has six tine bars to provide excellent ground cleaning and fast delivery of crop to the bale chamber. The camless pickup has been designed to increase output and reduce levels of maintenance.

Heavy-Duty Pick-Up

All McHale cam pick-ups have heavy-duty formed tine supports to ensure long service life, while all camless pick-ups are fitted with a fully welded tine bars. All Profi-Flo camless pick-ups are fitted with two extra columns of tines.

Efficient Crop Flow Delivery

On the Profi-Flo pick-up, the tine bands and feed augers are positioned close to the rotor to improve crop flow from the outside of the wide pick-up. Tapering the augers with 45° ends and removing the steel hydraulic pipes above the pick-up has resulted in a massive reduction in the potential for blockages to occur due to lumps, which ensures a consistent and even crop flow for producing high density bales.

Optimal Power Distribution

The rollers in the bale chamber are driven from the left-hand side of the machine and the pick-up and chopper unit are driven from the right-hand side of the machine. This system ensures direct, short transfer paths, leading to optimal power distribution to provide more torque and aid in the reduction of blockages.

1000rpm Gearbox (Optional)

In order to optimise machine performance, a 1000rpm gearbox is available as an optional upgrade on all machines in the McHale integrated baler wrapper range.

We recommend you speak with your local dealer or distributor regarding which gearbox is best suited to your requirements, based on your working conditions.

25 Knife Chopper Rotor

• A 25 knife chopper unit comes as standard on the McHale Fusion 4 range.
• A single bank of 25 knives provides a chop length of approximately 46mm.
• Chop length can be adjusted by removing knives.

ADJUSTABLE CHOP LENGTH

With selectable knives, the operator can vary the chop length by engaging or disengaging either knife bank. If fine chopping is required, the operator can choose to engage both knife banks. Should a longer chop length be required, the operator can disengage one bank of knives from the comfort and safety of the tractor cab.

REDUCED SHARPENING INTERVALS

When using both knife banks separately, if the first bank of knives become blunt, the operator can lower the first knife bank and raise the second bank. This reduces the downtime and allows the operator to continue working. By having consistently sharp knives, fuel consumption is reduced and the machine always delivers optimum chop.

OPERATOR COMFORT & SAFETY

A new sharp set of knives can be engaged, without the operator having to physically replace knives, ensuring a well chopped crop and continued high output. Should different chop lengths be required the operator can make the adjustments by engaging or disengaging the knife bank without having to leave the tractor cab.

• 1 - Drop the Floor

Should a blockage occur, the sound of the slip clutch alerts the operator, who can hydraulically lower the floor from the tractor cab.

• 2 - Re-engage the PTO

This widens the feed channel and on re-engaging the PTO, the blockage can be fed through.

• 3 - Reset the Floor

The floor can then be reset to its original position and baling can resume

Auto Unblock

When connected to an ISOBUS tractor, the drop floor will automatically lower when the software detects a blockage. Once the operator restarts the PTO and the blockage clears, the drop floor will automatically rise to its original position.

Automatic Drop Floor Reset

Automatic drop floor reset comes as standard on the McHale Fusion 4 Pro & Fusion 4 Plus. If a blockage occurs, the operator can press one button on the control terminal which lowers the floor. After the PTO is re-engaged and the blockage is fed through, the drop floor will automatically rise and the knives will reset to their original position.

Automatic Knife Drop Feature

This feature can be enabled on Fusion 4 Pro or Fusion 4 Plus machines from the control terminal in the cab. This allows the operator to chop the grass until the bale is almost complete, at which point the machine will automatically drop out the knives. Depending on the feeding method, this improves fodder distribution, keeping the bale neater when the net or film is removed.

Drop Floor Sensor

On Fusion 4 Pro and Fusion 4 Plus machines, the drop floor is equipped with a sensor to ensure the chop quality is consistent by indicating to the operator via the control terminal if the drop floor is even slightly open.

Heavy Duty Chains

High quality heavy-duty chains ensure reliable operation all around the machine. The main drive chain coming off the gearbox is a high tensile, heavy duty 100H endless chain for maximum strength. All other chains on the drive side of the bale chamber are inch and a quarter (20B). The rotor chain is inch duplex (16 B2) and all pick-up chains are three quarter inch (ASA 60H). New chain tensioners are fitted on all machines in the Fusion 4 range to allow for a spring to be tensioned by simply tightening a bolt at the end which replaces the need to manually release the spring and reattach.

Chamber Bearings

Single sprocket rollers on the chamber drive side are equipped with 50 mm shafts and bearings. Rollers under the most load are fitted with double row bearings. All rollers fitted with double sprockets are equipped with 55 mm shafts and double row 55 mm bearings. The non drive side of the bale chamber is also fitted with heavy duty 50 mm bearings.

Bale Density Adjustment

Bale density pressure has increased across all machines in the Fusion 4 range. On the McHale Fusion 4, the chamber pre-charge pressure can be easily adjusted by twisting the density control valve on the side of machine.

On the McHale Fusion 4 Pro and Fusion 4 Plus, the bale density can be adjusted from the tractor cab using the virtual density pressure gauge displayed on the control terminal.

Roller Design & Sealing

Bale chamber rollers are fitted with 50 mm bearings on the drive and non-drive side. Rollers fitted with double sprockets are equipped with 55 mm shafts and double row bearings. All roller ends are fitted with high performance self-cleaning seals that have a unique reverse-thread sealing system. This prevents crop from getting into the bearings; as the roller moves in one direction, the thread on the seal moves in the opposite direction, ensuring that any crop that tries to find its way into the bearing is automatically threaded out. The seals prevent the grease around the bearings from becoming contaminated by crop, resulting in increased reliability.

Automatic Greasing

The McHale Fusion 4 integrated baler wrapper range is fitted with a new automatic twin pump lubrication system which has a separate pump for grease and oil. This allows the oiling rate to be adjusted independently by the operator without affecting the greasing rate.

This pressurised system delivers a measured amount of grease around the machine after every bale cycle. Automatic greasing saves time as it reduces the amount of manual greasing to be done by the operator. It also ensures all bearings are greased under high pressure. This system ensures that the grease cartridge usage is spread out evenly over the 300-bale interval to 39 individual grease points. A lube alarm sounds after 300 bales to inform the operator to refill the grease cartridge.

The following components are greased:

• Bale Chamber – Drive Side
• Bale Chamber – Non-Drive Side
• Rotor Bearings – Drive Side
• Rotor Bearings – Non-Drive Side
• Pick-Up – Drive Gears

Pressurised Oiling System

The McHale Fusion 4 integrated baler wrapper range is fitted with a pressurised oiling system. Depending on working conditions, from the in-cab control terminal,
the operator can adjust the lubrication oil flow to the following chains that are serviced by the system:

• Chamber Drive Side Chains
• Rotor Drive Chain
• Pick-Up – Drive Chains
• Pick-Up – Cam Track

Endless Adjustment

Endless adjustment of tension to ensure optimum material usage and bale shape

Up to 1250 mm

Capacity to take rolls of net wrap up to 1300 mm in width and 4500m in length.

180-Degree Wrap

180-degree wrap around on the rubber feed roller, eliminating any net or film slippage while feeding

1 Bale Binding In Chamber & Wrapped Bale Being Tipped

When the bale on the back is wrapped the machine will hold the wrapped bale and automatically tip it while the next bale in the chamber is being bound with net or film. At this point the bale on the wrapper can be set to automatically tip if preferred.

2 McHale Patented Bale Transfer

Once the bale is formed, net or film is automatically applied and the chamber then splits like a clamshell. The lower section of the bale chamber then transfers the bale into the high speed vertical wrapping ring.

3 Baling while wrapping

Once the chamber is closed the operator can continue working and the fully automatic machine will start the wrapping process. In difficult ground conditions bales can be tipped at the operator’s convenience by pressing the tip button

Two 750 mm Dispensers

The vertical wrapping ring on the Fusion range is fitted with two 750mm dispensers. Using both dispensers, all machines in the Fusion 4 range take approximately 18 seconds to apply 4 layers of film and approximately 24 seconds to apply 6 layers of film. This means that the wrapping platform is always waiting for the next bale.

Easy Film Loading

Film can be loaded from the left hand side of the machine. After loading film on the first dispenser, the operator can push the index button and the dispensers will then rotate around and automatically stop at the loading position for the second dispenser. This allows the operator to easily load the second roll of film.

McHale have added internal panel lighting to aid the film loading process during night-time operations on all Fusion 4 Pro and Fusion 4 Plus machines.

Film Break Sensors

The dispensers are fitted with film break sensors, which notify the operator through the control console in the tractor cab if one or both dispensers run out of film. If one dispenser runs out of film, the machine will continue working by automatically slowing bale rotation, increasing the number of rotations of the wrapping ring to ensure that the bale is wrapped correctly. These sensors are now fitted with removable batteries which can be easily replaced.

Reliable Cut and Holds

On the last rotation of the wrapping cycle, the cut and hold rails extend out to be in the correct position to gather the wrapping film. The cut and hold retracts which gathers the wrapping film to one point where it is cut and held. The introduction of the new brushes on the gathering unit makes the Fusion 4’s performance even more reliable by reducing friction to eliminate plastic tearing, particularly in hot or wet conditions. The cut & holds now also feature a hydraulic tap to lock the cut and hold in the open position for the ease and safety of maintenance.

Fully Automatic

The ISOBUS control terminals, when combined with the load sensing valve on the McHale Fusion 4 Pro and the McHale Fusion 4 Plus, is capable of making baling and wrapping fully automatic.

Bale Density & Binding Adjustment

The ISOBUS control terminals allow for the bale density to be adjusted from the comfort of the tractor cab. From the control terminal, the operator can adjust the number of layers of net or film being applied to the bale. On the McHale Fusion 4 Plus, the operator can also adjust the stretch being applied to the film in the bale chamber from the control terminal in the tractor cab.

Auto Knife Drop

This feature allows for the operator to chop the forage until the bale is almost complete, at which point the machine will automatically lower the knives. Depending on the feeding method, this can improve fodder distribution and machine intake.

3D Manual Mode

When operating the machine in manual mode, a 3D image of the machine is displayed which allows the operator to select the relevant functions to control. In each function there is an information button that, when pressed, will show the current state of the function, for example:

• Netter – Net knife tripped or reset
• Chamber – Open/closed
• Chopper unit – Knives up/down
• Information Information – on/off
• Wrapping Ring – Dispenser position
• Bale Tip – Up/down
• Drop Floor- Up/down

Smart Switching Cameras

All control consoles are fitted with camera functionality as standard on the McHale Fusion 4 Pro and the Fusion 4 Plus. In manual mode, the operator can switch to camera mode to view the wrapper and rear of the machine. In automatic mode on all ISO-PLAY consoles, the camera image will appear at intelligent times on the screen during the baling cycle rather than on a time-based system, on existing machines.

The smart switching cameras can also be fully customised by the operator to suit their preferred view for when the bale is being transferred or being tipped.
If an additional camera is required on the McHale Fusion 4 Pro, the control console’s second camera input may be used. This second input is used for displaying the film binding process on the McHale Fusion 4 Plus machines.

Virtual Density Gauge

A Virtual Density Gauge is displayed on the screen of the connected ISOBUS terminal. This allows the operator to view the density of the bale being produced on screen rather than on the machine body.

During the baling process, a bale fill indicator shows the driver how the bale is forming in the chamber. When the desired density is achieved on the graph, a “Stop” warning is signalled to the driver to notify them that crop should stop being fed into the chamber.

CHAMBER FILM ACTS AS A WRAPPING LAYER

The plastic which is added to the barrel of the bale to keep the bale together also forms part of the wrapping process. This adds value by placing more plastic on the largest surface of the bale.

CHAMBER FILM RESULTS IN BETTER SHAPED BALES

When plastic is applied to the barrel of the bale, it can be stretched to the manufacturers recommendations, which is a higher ratio than can be achieved with net wrap or twine and as a result, the material is kept tighter, which ultimately results in better bale shape.

CHAMBER FILM DELIVERS HIGHER QUALITY SILAGE

As the plastic is being stretched during application to the barrel of the bale, it expels more air than net wrap does and as a consequence, results in better silage quality.

CHAMBER FILM MAKES RECYCLING EASIER

As plastic is used to both bind the bale in the bale chamber and to wrap the bale, on feed out, the farmer will be left with one form of waste. This reduces the time needed to feed the bale and avoids the unpleasant and time-consuming job of separating the twine or net wrap from the plastic before the plastic is recycled.
