System Description

Intermediate Door Position Indicator (If
Equipped)
A system that contains a cab mounted
indicator box and an additional door position
proximity switch. The indicator switch is
normally installed on the MHT LH lower
hopper assembly. The door switch is intended
to contact the inner door swing arm when the
dump doors are in a customer determined
intermediate position. When doors are open to
a customer determined position, the cab
control box will illuminate a green light and
provide an audio tone.
This system is designed to assist operators in
reduce/control
windrow heights when
performing stockpile operations.
MHT LUBE SYSTEM
The MHT is lubricated through central
lubrication blocks that may be connected to
the tractor auto lube system if installed.
Lubrication blocks service MHT axle A-frame,
hardpan rod, axle struts, hydraulic cylinder
pins and hitch ball socket assembly
MHT LIGHTING SYSTEM
The system contains brake, turn signal,
backing, clearance and work lights. Some
optional lighting features may include load,
backing and auxiliary equipment lighting. All
lighting is controlled by existing switches
mounted in the cab or modified by dealers to
operate at a junction box or added in-cab
control box.
