AUTOMATIC LIFTING SYSTEM
As a part of the hydraulic system, automatic lifting system
allows to lift and lower the equipment while ploughing field
without disturbing the position setting of the linkage arms
on the hydraulic unit.
Automatic lifting system (ALS) may be controlled
mechanically or electrically. The purpose of this system is
to provide the same ploughing depth at every position in the
field and to provide ease of use.
ALS is generally used to lift the equipment at the end of
the groove while ploughing without changing the settings
of hydraulic control levers, and to lower the equipment to
the previous position when the start of the new groove is
reached.
Warning buzzer system activates and warns the user when
the engine is stopped leaving the ALS on.
It is located on the dash panel on fruit garden models.
Lowering and lifting mechanism is also available on the
exterior of the tractor so that it can be controlled by drivers
from the outside.
Warning:
with equipment on the field. Equipment locking pins shall be
installed and ALS shall not be used while carrying load on the
road. Engine shall not be stopped when ALS is active.
