Active Density

Electronic variable density pressure regulation, results in increased bale density, due to the higher loads exerted on the bale at the optimum stages of bale formation.

Shape Sense Indicators

All V6760 machines are fitted with load sensing bale shape indicators that directly measure the bale pressure inside the chamber. By comparing the loading on each side of the chamber, the bale shape is calculated and then indicated to the operator via the control console, which side of the chamber needs to be filled. This direct measuring of the chamber pressure allows the bale shape indicators to be extremely accurate and responsive.

Intelli-Chamber

Chamber opening and closing speed has been increased for more productivity, with electronic proportional control of the chamber movement for improving operator comfort. Variable chamber opening height to suit the bale diameter and increase bale ejection speed.

Active Release

The McHale V6760 has a hydraulic bale kicker which lowers or raises as the chamber door opens or closes. Once the door opens, the kicker lowers to the ground to allow the bale to be ejected with more momentum and clear the door swing zone. The kicker raises to its original position when the bale passes over the paddle to ensure a safe ejection of the bale.

• 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.

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 Variable Chamber 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 Variable Chamber 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

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 variable chamber baler range.

ADJUSTABLE CHOP LENGTH

With selectable knives, the operator can vary their chop length by engaging or disengaging either knife bank. If fine chopping is required, the operator can choose to engage both knife banks. A reduction in chop length can also be quickly and easily achieved without the operator having to remove knives.

CONSISTENTLY SHARP KNIVES

When the operator is using only one knife bank, this can easily be swapped to the second knife bank from the cab to provide a fresh set of sharp knives. By having consistently sharp knives, fuel consumption is reduced as less power is required to chop the crop with sharp knives. Without the operator having to physically replace knives, a new sharp set of knives can be engaged, ensuring a well chopped crop and continued high output. Should different chop lengths be required the operator can make the adjustments

OPERATOR COMFORT

Without the operator having to physically replace knives, a new sharp set of knives can be engaged, ensuring a well chopped crop and continued high output. Should different chop lengths be required the operator can make the adjustments without having to alter the knives.

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. 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.

McHale have developed a bale chamber that can quickly form the bale from the start. The operator can commence baling at full speed as the progressive density system can quickly adjust to ensure that pressure is exerted on the crop right from the core of the bale, regardless of bale size.

This is done by four heavy-duty springs that pressurise the crop at the start of the baling process. The tension placed on the crop by these large springs allows for the perfect start to the bale. The spring tension on the belts ensures easy bale formation and a properly formed core.

As the bale is forming inside the chamber, the hydraulics take over the tensioning of the belt(s) from the four large springs. Two hydraulic rams control the tension on the chamber belt(s) as the bale forms inside the chamber.

Just like the core of the bale, the outer layers are compressed at the same consistent pressure using both springs and hydraulics until the set bale density and size is reached.

Double Drive

In more difficult conditions, such as wet heavy grass, if the primary drive slips slightly, the double drive will engage in order to aid belt and material rotation in the chamber. This double drive helps bale formation as a constant pressure is kept on the chamber belts which results in the production of a solid and uniform bale even when dealing with a wet and heavy crop.

A cleaning auger is fitted to the double drive system in order to prevent crop build up and allow the double drive to aid bale rotation when working in wet or sugary crops.

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.

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

Greasing

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 V6760 machines. 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

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

Bale Settings

The ISO-PLAY 7 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 0.6–1.68m (2’–5’6″) on the V6760. 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.

Shape Sense 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.
