991 LB Single Dispenser

991 LB Single Dispenser Linkage 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 L range of linkage round bale wrappers is the first choice for farmers and contractors who are interested in wrapping bales at the storage site. The 991 L range offers the perfect blend of tried and tested technology with solid construction and reliable performance. There are three models in the 991 linkage round bale wrapper range.

The 991 LB is a manually operated machine where four individual levers control all wrapping functions. Powered by either a tractor or an independent power pack, the 991 LB control valve can either be mounted beside the dispenser post or just inside the tractor cab. The control unit measures the revolutions per minute and monitors the number of layers as they are being applied to the bale. The control unit enables the operator to change the number of film layers and store bale totals from different jobs.

Built To Last

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 asymmetric bales.

Extra Film Storage with Easy Handling

The 991 L range can carry 3 rolls of film:

1 roll (dispenser) + 2 rolls (film storage)

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 minimised.

Automatic Film Break Sensors

Automatic film break sensors monitor the plastic as it wraps the bale. If one roll breaks or runs

out, the operator is notified on screen and the machine switches to single dispenser mode.

It will automatically compensate to ensure bales are wrapped correctly. If both rolls break or finish at the same time, the cycle will resume when the rolls are reset.

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 aluminium 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.
