Features
Independent Load Sensing Hydraulic System
The McHale 998 square bale wrapper is equipped with a fully integrated, PTO driven, load sensing hydraulic system allowing for a low horsepower requirement.
This simplifies tractor change over and delivers consistent performance, eliminating problems associated with different tractor hydraulic systems, oil flows and oil temperatures. The stand-alone load sensing hydraulic system also reduces the risk of oil contamination.
Conveyor Loading
The front-loading conveyor on the McHale 998 allows for effortless square bale loading. This system allows for 3 bales to be moved together.
As one bale is being unloaded at the rear of the machine, the next bale is being transported from the front of the machine onto the conveyor. The conveyor can also be used to pick the third bale and carry it as the machine finishes the wrapping process. If the operator wishes to do so, the Auto Load function can be activated which will enable the bale to be automatically loaded onto the conveyor once detected by the sensor. This allows the operator to simply drive the tractor without having to worry about operating the machine.

Patented Oscillating Rollers
The patented oscillating rollers on the 998 High Speed square bale wrapper cradle the bale between the rollers as it is being wrapped. The oscillating rollers rotate the square bale at a uniform pace ensuring that the square bale receives the correct and even overlap, which ensures a tight seal and a high-quality finished square bale of crop.

This consistently accurate bale movement results in a superior wrap every time as the bale is not relying on gravity. The 4 oscillating rollers are in contact with the bale at all times in order to control bale rotation which ensures the wrap is evenly applied. To ensure wrap is evenly applied, bale rotation is monitored through the use of the two potentiometers. These count the corners of the bale and ensure the correct amount of plastic is applied irrespective of the size of the bale.
Patented Roller Angle Measuring & Levelling System
The 998 High Speed features a patented roller angle measuring and levelling system, which gives a consistent and even wrap regardless of square bale size or shape.
The patented roller angle measuring and levelling system allows for extra care wrapping. When the extra care program is selected in the control box, bale rotation is slowed down at the corners of the bale and additional plastic is applied which ensures good quality square bales are produced. This careful wrapping program ensures even odd shaped bales can be wrapped at eight predetermined points.
Hydraulic Cut & Hold System
As with all McHale bale wrappers, the reliability of the cut and hold systems is a feature of the utmost importance. On the last rotation of the wrapping cycle, the cut and holds extend out and the wrapping film is gently gathered in the cut and hold rails.
Once supported, the cut and hold gathers the wrapping film to one point where it is cut and held. By gathering the plastic to one point, this reliable system ensures better grip and provides more consistent superior performance, particularly when working in extreme hot or wet conditions.
Quick Fit Dispensers
The McHale 998 features two 750mm aluminum dispensers. The units are designed so that the angle that they work at during the wrapping cycle stays constant in order to maintain a consistent stretch.

This gives a more even stretch throughout the roll of film which maximizes film usage. The dispenser unit consists of two aluminum rollers, which are geared to each other with robust steel gears of different ratios. If required, the stretch can be adjusted by changing the gears. The dispenser units also feature the McHale user friendly quick fit plastic loading system which simplifies film changing.
Film Break Sensors
The twin satellite dispensers are fitted with film break sensors, which notify the operator through the control console in the tractor cab if one or both dispensers run out of film.
If one dispenser runs out of film, the machine will continue working and automatically slow bale rotation while also increasing the number of rotations of wrapping arms to ensure that the bale is wrapped correctly.
Easy Film Loading
On the McHale 998, the dispenser’s lock and load system simplifies film loading.
Read More
When removing the core of the used roll of plastic the dispenser bobbin locks in place. When a new roll of plastic is in the loading position, it can be locked in place by simply pulling the cord on the dispenser.
Film can be loaded from the left-hand side of the machine with the help of a film replacement loading step.
After loading film on the first dispenser, the operator can push the index button located on the drawbar, and the dispensers will then rotate around and automatically stop at the loading position for the second dispenser. This allows the operator to easily load the second roll of film from the one location.

Extra Film Storage
The McHale 998 High Speed can carry 12 rolls of film: 2 rolls in the wrapping dispensers and 10 spare rolls in film storage.
A Film Replacement Loading Step is fitted on all machines to aid the operator when changing a roll of film. This step can be extended out when changing a roll of film and folded back to its original position when the machine is in operation in the field or in transport.

Laser Sensors
Through the use of Laser Sensors, the 998 High Speed can operate at approximately 40rpm in High Speed Wrapping Mode. These sensors allow for the satellite wrapping arms to safely increase in speed.
Should someone come within the close vicinity of the machine, the sensors will detect their presence and slow the wrapping arms down to a lower speed. This function has the ability to deliver 35% more output over a standard 998 Based On Field Test Conducted in 2017.
Expert Control Console
All 998 High Speed square bale wrappers feature an In-cab Expert control console to allow the operator to control the machine at the touch of a button. The McHale 998 High Speed is a fully automatic machine thanks to the continuous automatic cycle which operates all the wrapping functionality of the machine.
Expert Control Console Functions
Bale Settings & Continuous Automatic Cycle Function
The Expert control console enables the operator to change the bale size and select the desired number of film layers to be applied to the bale.
When set, the continuous automatic cycle function operates the complete cycle from start to finish. This function increases output as when one bale is unloading, the next bale is being transferred from the ground onto the conveyor. Once in position on the wrapping conveyor, the wrapping cycle commences automatically.
Customize the Wrapping Program
From the control console, it is possible for the operator to select the wrap start position and to customize the wrapping program. This provides the operator with the ability to apply more plastic at eight points on the surface of the bale and store the customized program for later jobs which have the same bale size.
Adjustable Maximum Speed & Extra Care Wrapping
An Adjustable Maximum Speed setting is fitted as standard on the McHale 998 High Speed, which allows the operator to set the speed at which they wish to work at from the control console in the tractor cab. This speed can vary from 25rpm to 40rpm depending on the conditions.
The operator can also select extra care wrapping, which makes the McHale 998 square bale wrapper range apply additional plastic on the corners of the bale which is particularly beneficial to rectangular shaped bales.
Wired Handpiece Control
A new wired handpiece control comes as standard to work with the McHale 998 High Speed square bale wrapper.
The new wired handpiece control gives the operator more ergonomic access to the following machine functions:
Conveyor Forward
Conveyor Reverse
Auto Start & Stop

998 High Speed Optional Extras
Radio Remote Control Kit
Should you wish to use the McHale 998 or 998 High Speed bale wrapper for static wrapping, a new radio remote-control kit is available. This allows the machine to be efficiently used as a static machine for wrapping round or square bales. An operator can load the bale wrapper using a loader and easily activate an automatic cycle by using the radio remote control.
Static Wrapping Unloading Conveyor
The McHale 998 and 998 High Speed is available with an optional rear unloading conveyor. This unloading conveyor can be used when static wrapping to allow the careful unloading of a bale from the wrapper. To avoid damage to the plastic, the bale is unloaded from the wrapper onto the conveyor where it is held until it is collected by the loader and placed in the stack. This ensures the wrapped bale has no contact with the ground. When the wrapping job is complete, the unloading conveyor is neatly folded up for transport.
Air Brakes
All machines in the McHale 998 square bale wrapper range come fitted with hydraulic brakes as standard but can be specified with air brakes as an optional extra.
