Mechanical Leveling Cylinder Stops
Some tire configurations may come into contact
with the side panel when the combine is leveled
over. Limit switches will prevent this contact,
however, Hillco requires installing mechanical
leveling cylinder stops. This will prevent damage
in the event of hydraulic or electrical failure. After
setting the carriage angle limits verify there is 1"
between the tire and the closest contact point or 1/4"
between the driveshafts and the leveling system
chassis. Add cylinder stops to prevent the cylinder
from over-leveling the combine. Contact Hillco for
these cylinder stops.
Notice
Set Carriage Angle Limits prior to
installing Leveling Cylinder Stops.
Carriage
The carriage is designed to support the combine's
chassis while allowing the combine to rotate through
full range of motion. It consists of an undercarriage
and an overcarriage. The drive wheels, final drives,
and transmission are mounted to the undercarriage.
The overcarriage bolts to the combine's axle and
chassis. The leveling cylinders connect to the
overcarriage and the undercarriage. The carriage
raises the combine chassis eight inches to prevent
the tires from coming into contact with the side
panels.
Hydraulic Leveling Cylinders and
Counter-Balance Valves
There are two leveling cylinders located on the
rearward side of the leveling system's carriage.
These cylinders are pressurized by the leveling
hydraulic valve to tilt the combine chassis to correct
for slope changes.
equipped with built in hydraulic counter-balance
valves that positively lock the oil into the cylinders
until a pressure signal is sent from the hydraulic
leveling valve. These counter-balance valves lock
the chassis position in the event of hydraulic hose
failure.
