Product Description
The Hillco Hillside Leveling System is designed for John Deere S Series combines. Hillco designed the Hillside
Leveling System to maintain the combine's thrashing capacity and harvesting efficiency on contours of slopes up
to 27%. This leveling system is designed to be installed with little modification to the combine.
The Hillside Leveling System tilts the combine's chassis laterally, automatically compensating for slopes up to
27% as it moves across sloping terrain. The thrashing platform remains level and allows both the combine and
the operator to perform at maximum efficiency.
The leveling system uses a clinometer to sense the combine's chassis position in relation to "level". As the
combine moves onto a slope, the chassis leans out of level and the clinometer senses the deviation and sends
a signal to the controller. The controller opens the appropriate leveling valve. The leveling valve allows hydraulic
oil to flow into the leveling cylinder. The cylinders tilt the combine's chassis to correct for the tilt, bringing the
chassis back to level.
As the combine's chassis levels, the master header tilt cylinder pushes hydraulic oil to the header tilt cylinder,
which counter-rotates the header to keep it parallel to the ground. The operator can manually adjust the header's
position or, alternately, may use the combine's original lateral tilt electronics and sensor-equipped header to
automatically compensate for varying ground contours.
