991 BC Cable Controlled 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 BC round bale wrapper is the entry level machine in the 991 B range. The McHale 991 BC uses four individual levers to control all wrapping functions. The cable-controlled levers on this round bale wrapper allow the operator to control:
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 asymmetric 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 the 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 Dispensers
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
Used on the base level machines, these simple levers control the functions on the wrappers. Used on both the 991 LB and the 991 BC, the levers control the lift arm (991 BC only), wrapping table, cut & hold and bale tip.
WIZARD Control System
The balewrap monitor controls the number of layers of wrap being applied to the bale and keeps track of the number of bales wrapped. The 3.5m long cable features an auto stop function which locks the rotation lever after 2 rotations and stops at the pre-set number of layer rotations.
