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 |
The servo operated system on the 991 BJS uses low-pressure hydraulics, which provides a similar feel to the joystick used in telescopic loaders. On the 991 BJS the wizard control console allows the operator to select the following:
