Mechanical Lower Link Sensing Hydraulics - New Holland T6010 Operator's Manual

MECHANICAL LOWER LINK SENSING
HYDRAULICS (where fitted)
Your tractor is equipped with an hydraulic system
providing accurate and sensitive control over a wide
range of operating conditions. Two systems are
employed, dependent upon the specification level of
your tractor.
The basic hydraulic system, as discussed in this
section of the Manual, is a mechanically controlled
system that offers Position Control and Draft Control
sensed through the lower links of the 3-point linkage.
The system is controlled by the Draft Control lever (3)
the Position Control lever (2) and the fast raise button
(1). The fast raise button will fully raise the 3--point
linkage (and attached implement) independently of
the Position or Draft Control levers.
Position Control provides accurate and sensitive
control of implements, such as sprayers, rakes,
graders, etc., that operate above the ground. Once
set, the position of the lower links will remain at a
constant height unless adjusted using the lift control
lever.
Draft Control is most suitable for mounted
implements operating in the ground. Changes in the
working depth or changes in soil resistance cause
the draft loading on the implement to increase or
decrease.
Pre- -operation Checks
CAUTION
Before starting the engine, always ensure that the
fast raise button (1) is pushed in, as shown, to
prevent inadvertent raising of the 3--point linkage.
IMPORTANT: Some mounted or semi- -mounted
equipment may interfere with, and damage the cab.
To avoid the possibility of cab damage, check for
adequate clearance by slowly raising the equipment
using the Position Control lever (2). If any part of
the equipment comes closer than 100 mm (4 in.) to
the cab, stop raising. Stop the engine, lower
equipment to the ground and adjust the height limiter
cam.
