Offering innovative ideas to allow you to work smarter, whilst achieving more output, the McHale name has become synonymous with the production of robust and reliable machines, making McHale the number one choice for professional users.
The McHale V6750 is a semi-automatic variable chamber baler capable of producing bales from 0.6–1.68m (2’–5’6″).
The machine is fitted with a 15-knife chopper unit and heavy-duty rotor. A double drive system aids belt rotation and bale formation to allow the machine to operate in the toughest of conditions.
The machine comes with centralised grease blocks as standard. Automatic greasing is available as an optional extra. Net and bale density can be adjusted from the cab through the Expert Plus control console. The machine is fitted with 500/50-22.5 tyres as standard.
Built To Last
Over the last decade, McHale has designed and developed various types of pick-ups. After extensive testing, McHale decided it will offer customers the choice of 2 pick-up options depending on their working conditions:
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 Fixed Chamber Baler Range are fitted with 5 tine bars for excellent ground cleaning and delivery of crop to the bale chamber. A side inspection port allows the operator to quickly check and change the cam bearings if needed.
All McHale cam pick-ups have heavy-duty tine bar supports to ensure long service life. McHale have also developed a pick-up tine designed to lift even the shortest of crop
A 2.1m camless pick-up is available as an option on all machines in the McHale Fixed Chamber Baler Range. Six tine bars are fitted to all McHale camless pick-ups to provide excellent ground cleaning and fast delivery of crop to the bale chamber.
The camless pick-up has been designed to increase output, reduce levels of maintenance and perform better in certain conditions.
All camless pick-ups are fitted with a fully welded tine bar. McHale have also developed a pick-up tine designed to lift even the shortest of crop
Over the course of a baling season, machines have to work with different volumes of crop. McHale have designed an adaptive intake which allows the intake area to automatically adjust for light and heavy crops to facilitate a smooth crop flow into the chamber.
Split Drive GearBox
A 540rpm Split Drive Gearbox is fitted to all machines in the McHale Fixed Chamber Range as standard. The gearbox design ensures that power is evenly distributed to both sides of the mac
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.
1000rpm Gearbox (Optional)
In order to optimise machine performance, a 1000rpm gearbox is available as an optional upgrade on all machines in the McHale fixed chamber baler 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.
The star shaped feed rotor ensures a high-capacity flow of crop into the bale chamber. McHale have designed 3 rotors for the Variable Chamber Baler Range.
The flights on the rotor are laid out in a spiral formation to achieve consistent crop flow. As crop enters the rotor, rotating flights feeds it to the bale chamber. These ensure high output, while the star layout reduces the load peaks as the machines work in heavy swaths.
- The feed rotor or chopping unit boasts a heavy-duty rotor and comb.
- The flights are welded on both sides for superior strength and on the drive side the rotor is fitted with a double row bearing with a long service life.

To ensure a consistent and even chop quality, two chopping options have been developed for the McHale Variable Chamber Range.
15 Knife Chopper Unit (Standard)
The 15 knife chopper unit is the standard chopper unit on the McHale F5500. A bank of 15 knives provides a chop length of approximately 65mm.
Number of Knives
25 Knife Chopper Unit (Optional)
The 25 knife chopper unit is available as an option on the McHale F5500. A bank of 25 knives provides a chop length of approximately 46mm.
Number of Knives
The knives in the chopping unit are made from hardened tool steel, which ensures long life and maximum productivity by reducing the downtime associated with knife sharpening. The serrated knife edge creates multiple points of contact with the crop to ensure a consistent chop quality is achieved.
To ensure that the machine always delivers a good chop quality, two monitoring systems have been put in place on the V6750.
- Knife working pressure is monitored and displayed on the control console.
- A sensor monitors the distance between the top of the knife and the spine on the rotor.
The knives in the chopping unit can be engaged and disengaged from the tractor cab. When engaged, the knives extend into the spine of the rotor, which ensures a consistent chop quality.
- A primary hydraulic knife protection system protects the knife bank(s) should it encounter a foreign object.
- A secondary protection system is in place on each individual knife.
Selectable Knife System
All McHale V6750 machines have the option to be fitted with a selectable knife system. Various knife configurations can be chosen depending on the knife bank specification.
15 Knife Bank Options
0, 7, 8, 15 Knifes
25 Knife Bank Options
0, 12, 13, 25 Knifes
BENEFITS OF SELECTABLE 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.
For over a decade, all machines in the variable chamber baler range are fitted with the McHale Drop floor unblocking system, a feature which operators have come to love for it’s simplicity of use and effective unblocking cycle.
The McHale Variable Chamber Baler Range is fitted with a Drop Floor Unblocking System, which means blockages can be fed through in three simple steps.
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. When operating the drop floor cycle, the knives and the drop floor drop together during the unblocking process, giving even more clearance to allow the blockage to be fed through.
2 – Re-engage the PTO
This widens the feed channel at both the front and rear of the drop floor where the blockage is more likely to occur. By lowering the front and rear of the drop floor, the blockage can be fed through and effectively cleared when the PTO is re-engaged.
3 – Reset the Floor
The floor can then be reset to its original position and baling can resume. On the F5500,F5600 and F5600 Plus the drop floor is equipped with a drop floor sensor to ensure the chop quality is consistent by indicating to the operator via the control box if the drop floor is open and the knives are down.
Bale Chamber & Bale Sizes
The bale chamber on the McHale variable chamber baler range is comprised of heavy-duty endless belt(s). The belts are extremely hard wearing and are reinforced with synthetic material, which ensures that the belt(s) can absorb and apply high pressure to the material in the Bale chamber.
The V6740 can make a bale from 0.6m (2 ‘) to 1.68m (5 ‘6 “)
The bale size can be adjusted up from the minimum setting in increments of 10mm (2/5″)
Bale Chamber – Belt Options
Three Endless Belts
All V6/ V8 variable chamber balers are equipped with 3 heavy duty endless belts as standard. These strong belts exert high pressure in order to form a dense bale in the chamber and are manufactured to the highest of standards using layers of synthetic and rubber material to form a durable endless belt with no joins.
Single Belt (Optional)
A single full width endless belt is also available as an optional extra on the V6740 and V6750. This full width belt reduces crop loss, particularly in alfalfa and provides better belt traction for the operator compared to multiple endless belts.
Bale Chamber Primary Drive
A heavy-duty drive system powers belt and bale rotation on all machines in the variable chamber baler range. On the McHale V6740, a primary drive system is fitted to ensure belt rotation and bale formation.
Bale Shape Indicators
Ultra-sonic bale shape indicators are fitted to all McHale Variable Chamber Balers and indicate to the operator via the control console which side of the chamber needs to be filled.
Mechanical Tailgate Locking System
The tailgates on all McHale variable chamber balers are fitted with a pair of mechanical locks, which keep the bale chamber securely closed. These locks remain activated until, the progressive density system reaches the preset bale size and density and the required amount of net has been applied. This eliminates the need for the chamber door to rely on hydraulic pressure when making high density bales.
Oiling & Greasing
The McHale variable chamber baler range of balers are all fitted with a continuous oiling system. Once the PTO is engaged, the continuous oiling system constantly lubricates the chains to ensure a long lifetime. A lube alarm sounds after 300 bales to inform the operator to refill the oil tank.
Continuous Oiling System
The continuous oiling system on the machine is driven off the gearbox and delivers oil to the following chains:
- Chamber Drive Side Chains
- Rotor Drive Chain
- Pick-Up – Drive Chains
- Pick-Up – Cam Track
- Pick-Up – Drive Gears
All machines come fitted with a number of manual greasing points which are easily accessible throughout the baler either individually or through a centralised greasing block. The following bearings highlighted below are greased:
- Bale Chamber – Drive Side
- Bale Chamber – Non-Drive Side
- Rotor Bearings – Drive Side
- Rotor Bearings – Non-Drive Side.
High Performance Netter
A high performance netter has been designed and developed for the McHale Variable Chamber Baler Range. This netter is very reliable and comprises of a moving roller which allows the roll of net to rotate as it is being applied to ensure even net application.
A simple yet very effective netting system comprising of a moving roller allows the roll of net to rotate as it is being applied to ensure even net application. Net is stretched around the bale using a hydraulic brake. The brake places a resistance on the speed at which the roll of net can rotate, the greater the resistance the more stretch that is applied to the net. The operator can adjust net tension without having to leave the comfort and safety of the tractor cab.
McHale V6 & V8 balers are fitted with a bale discharge sensor, which notifies the driver when the bale has left the bale chamber and has passed over the heavy-duty bale kicker ensuring a clean separation between the machine and the netted high-density bale. Storage for two extra rolls of net is also provided on the baler platform.
The high performance netter is extremely reliable and features:
Endless adjustment of tension to ensure optimum bind material usage and bale shape
Up to 1300 mm
Capacity to take rolls of net wrap up to 1300 mm in width and 4500m in length.
180-degree wrap around on the rubber feed roller, eliminating any net or film slippage while feeding
Expert Plus Control Console
The McHale V6750 is fitted with an Expert Plus control console, which has a large graphic display.
From the control console in the tractor cab the operator can adjust the following;
- Core Size & Bale Size
- Core Density & Bale Density
- Revolutions of Net Being Applied
Expert Plus Control Console Features
The Expert Plus console, also gives the operator the choice of selecting a soft or hard bale core, depending on the customers feed out requirements. The control console can also store ten bale count totals so the operator can record ten different counts that may be associated with different fields or different customers
The bale diameter can be adjusted on the control console from 0.6–1.68m (2’–5’6″) on the V6740. The preset diameter setting is displayed on the bottom information block on the main screen and a live diameter reading is displayed as the bale is being formed. There is also a vertical bar graph which shows progress as the bale is being made.
A bale profile setting retains the operators personal setting choice from core diameter, bale diameter, core density, bale density, net layers and net stretch for use in different crops. There are 5 bale profile settings to choose from. Each profile will retain its own individual settings so that the machine can easily be changed to work in different crops without needing to change a lot of settings.
Bale Shape Indicators
The variable chamber baler range is fitted with bale shape indicators, which indicate to the driver via the control box, which side of the chamber needs to be filled, ensuring that when the machine works in a light swath that the best bale shape is achieved. The bale shape indicator arrows are also accompanied by a series of beeps so the operator does not need to watch the screen. A low tone is emitted when the operator needs to steer left and a higher tone for when the operator needs to steer right.
McHale machines work in different conditions around the world. To optimise machine performance, we offer a number of options in the McHale fixed chamber range. We recommend you speak with your local dealer/distributor as regards the best configuration to meet your requirements
The 2.1m camless pick-up runs smoothly, particularly in short crop, and requires less maintenance due to a reduced number of rotating parts. All camless pick-ups in the McHale variable chamber baler range are fitted with six tine bars and a double crop roller to provide excellent ground cleaning and fast delivery of crop to the rotor.
Rotor / Chopper Unit
The 25 knife rotor and chopper unit is available as an option on the McHale V6750,V8950 and Fusion Vario variable chamber machines and delivers a chop length of approximately 46mm.
A selectable knife system consists of two knife banks which allow for various knife configurations to be chosen depending on the knife bank specification. If a machine is equipped with 25 knives, then a bank of 12 and a bank of 13 knives are available to be chosen from. Where a machine is equipped with a 15 knife chopping unit, then a bank of 7 and a bank of 8 knives are available to be selected. If no chopping is required then the operator can select for no knives to be engaged. On all V8950 machines, knife selection is engaged from the baler. On all Fusion Vario machines, knife selection can be decided from the tractor cab.
McHale machines work in different conditions around the world so in order to optimise machine performance, a 1000rpm gearbox is available as an optional upgrade on all machines in the McHale baler range.
All balers in the McHale V6 variable chamber baler range can be equipped with brakes as an optional extra. McHale offer the choice of hydraulic or air brakes. All McHale Fusion Vario machines come fitted with hydraulic brakes as standard but can be specified with air brakes as an optional extra.
A single, full width, endless belt exerts a high pressure on the crop in order to form a dense bale in the chamber. Heavy-duty belts are manufactured to the highest of standards using layers of synthetic and rubber material to form a durable endless belt with no joins. This full width belt reduces crop loss, particularly in alfalfa and provides better belt traction for the operator compared to multiple endless belts.
Automatic greasing is available as an option on all McHale V8950 machines. Automatic greasing saves time as it reduces the amount of manual greasing to be done by the operator. All drive and non-drive side chamber bearings and rotor bearings are greased as the machine is working through the automatic greasing cycle. A measured amount of grease is distributed around the machine every time the bale chamber door opens on the McHale V8950. The grease cartridge should be replaced after 1200 bales.
ISOBUS is available as an optional extra on all McHale V6750 and V8950 machines. When the machine is fitted with ISOBUS, it can be plugged into any ISOBUS tractor connection and operated through the terminal in the cab.
McHale offer a number of tyre upgrades depending on customer preferences and ground conditions.
