991 BJS Servo Joystick Trailed Round Bale Wrapper
McHale’s round bale wrapper range has been designed with the demands of today’s farmer and contractor in mind. This common-sense approach to design ensures that each machine’s operation is kept simple and user friendly.
Farmers and contractors all over the world are under pressure to reduce costs and increase output. To help with this, McHale concentrate on features like the patented hydraulic ground supported bale damper system, patented high-speed transfer system, patented tip rollers, hydraulically operated cut & hold system, 750mm dispensers and high specification components.
These features ensure long working life, reliability and a machine rugged enough to handle the toughest crops, heaviest bales and roughest ground conditions.
The McHale 991 BJS is a servo joystick machine which uses low pressure hydraulics to provide a smooth controlled transition between functions. This system is often favoured by high-end users as it allows full control over the functions of the machine. Each wrapping function is controlled through a sequence of joystick movements. The servo joystick allows the operator to control the following functions:
Lift Arm
Wrapping Table
Cut & Hold
Bale Tip
Features
Ground Supported Damper System
The patented bale damper system gently lowers the bale to the ground while eliminating any stress on the chassis of the machine.
When tipping a bale, the heavy-duty damper is also lifted to cradle it, while the second arm is lowered automatically to the ground. This allows the heaviest of bales to be gently lowered to the ground, eliminating any damage.
Lift Arm & Wrapping Table
The 991 BC and BJS lift arms are operated manually. On the 991 BE and High-Speed, the auto lift function places the bale on the wrapping table automatically.
The wrapping table has four heavy-duty belts, which ensure smooth and consistent bale rotation even when dealing with loose or asymmetrical bales.
Extra Film Storage with Easy Handling
The 991 B range can carry 7 rolls of film:
1 roll (dispenser) + 6 rolls (film storage)
Optional Side Tip
An optional side tip is available on all trailed machines to place bales on their ends after wrapping is complete.
This helps by:
Tipping bales onto where they have more plastic, thus reducing damage in stubbly fields.
Allowing round bales to hold their shape better.
Stopping the bale from rolling when ejected on slopes.
Cut & Hold System
At the end of the wrapping cycle, the hydraulically operated cut & hold system cuts and holds the film in position ready to wrap the next bale.
Uniquely designed, this system works reliably and consistently in all weather conditions. The plastic is gathered to one point, cut, and then pulled against the side of the bale so that tails are minimized.
Automatic Film Break Sensors
Automatic film break sensors monitor the plastic as it leaves the dispenser rollers. If plastic breaks or runs out, the machine will notify the operator via the control console.
If needed, the 991 High-Speed automatically switches to single dispenser mode, where the machine compensates for the broken or empty roll and ensures the bale is wrapped correctly.
Easy Load Dispenser
The McHale lock and load system makes film loading quick and easy by locking the dispenser bobbin up when unloading and locking it back down by simply pulling the cable.
All machines are fitted with 750mm aluminum dispensers, which provide a 70% film stretch. Other film stretch options are available on request.
Shear Bolt Unit
A Shear Bolt protects the gearbox when wrapping poorly shaped bales. All machines are now driven by a heavier gearbox than previous models.
The gears are wider in diameter and have a larger tooth module on them, making them easier to drive. This heavy-duty gearbox contains a new key way protection system, which replaces the old roll pin system.
Control Options
The single joystick servo controller on the 991 BJS uses low-pressure hydraulics, similar to telescopic loader controllers, to smoothly transition between the four functions: lift arm, wrapping table, cut & hold and bale tip.
WIZARD Control System
On the 991 BJS the wizard control console allows the operator to select the following:
Set the number of layers to be applies
Set and monitor the revolutions per minute of the bale wrapping table
Store two job totals
