Figure 3.55: Lift Cylinder
Two hydraulic cylinders (A), one at each end of the carrier, raise
or lower the rotary disc pull-type when the tractor
’
s cylinder
control lever is activated.
The lift system is equipped with a lock-out valve (B) at each
cylinder which prevents the cylinder from extending or
retracting due to accidental movement of the lift control. Refer
to
3.11.2
Lift Control
The lift control is not normally used to control cutting height because cutting is usually performed with the cutterbar on the
ground. This control is used to raise the rotary disc pull-type to clear obstacles and windrows during field operation, to
adjust the rotary disc pull-type height for maintenance, and to raise the rotary disc pull-type for storage or for transport
behind a tractor.
WARNING
Be sure all bystanders are clear of the machine before raising or lowering the rotary disc pull-type.
