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:

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 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

Camless Pick-Up

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

Heavy-Duty Pick-Up

The specially designed McHale pick-up is positioned close to the rotor to improve delivery of the crop through the rotor to the bale chamber. Large diameter lateral feed augers help direct crop to the bale chamber ensuring a consistent and even crop flow for producing high density bales.

Adaptive Intake

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.

Read More

The adaptive intake plate sits higher in low volumes of crop and can adjust to a lower position for higher volumes of crop. This avoids peak loads and results in higher daily throughput regardless of working condition.

Split Drive GearBox

A 540rpm Split Drive Gearbox is fitted to all machines in the McHale Variable Chamber Range as standard. The gearbox design ensures that power is evenly distributed to both sides of the machine. 

Read More

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.

Read More

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.

Selectable Knife System

All McHale V8950 machines have the option to be fitted with a selectable knife system. Various knife configurations can be chosen depending on the knife bank specification.

Read More

15 Knife Bank Options 

0, 7, 8, 15 Knifes

25 Knife Bank Options

0, 12, 13, 25 Knifes



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.


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.


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.

Drop Floor

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.

Read More

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.

Read More

Bale Sizes 

The V8940 can make a bale from 0.6m (2 ‘) to 1.9m (6 ‘3 “)

 Size Increments

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 Double Drive

A heavy-duty drive system powers belt and bale rotation on all machines in the variable chamber baler range. On the McHale V8950, a primary drive system is fitted to ensure belt rotation and bale formation.

Read More

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.
Read More

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.

Automatic Greasing (Optional)

Automatic greasing is available as an option on all McHale V6750 and V8950 machine. A pressurised system delivers a measured amount of grease around the baler every time a bale is ejected from the bale chamber. Automatic greasing saves time as it reduces the amount of manual greasing to be done by the operator. The grease cartridge should be refilled after 1200 bales

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.

Read More

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

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

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

Expert Plus Control Console

The McHale V8950 is fitted with an Expert Plus control console, which has a large graphic display.

Read More

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

Bale Settings

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

Bale Size

The bale diameter can be adjusted on the control console from 0.6–1.9m (2’–6’3″) on the V8940. 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.

Bale Profiles

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
