1. DESCRIPTION AND OPERATION
Loader backhoes are available with center pivot or
sideshift backhoe attachment.
On center pivot machines the backhoe pivots on a
fixed central point at the rear of the machine.
Independently operated stabilizers are attached to
the base of the chassis and pivot about an arc to
raise or lower each side of the machine.
On sideshift machines the backhoe is attached to a
carriage hydraulically clamped to the machine frame.
This allows the operator to reposition the carriage on
the frame and to adjust the position of the backhoe
attachment to suit the operating conditions.
The machine is raised using two vertical stabilisers
attached to each side of the machine.
Each stabilizer is independently operated using:
Z levers (1) and (2) on loader backhoe control mod-
els mechanical;
Z control levers (3) and (4) on loader backhoe pilot
control models.
