ADC2350 Hydraulic Circuits
The implement has one or two hydraulic circuits (with a
low pressure sump return line). The standard circuit
powers lift, fold and weight-transfer functions, controlled
by a valve block on the left front of the implement. An
optional circuit operates the markers.
If the tractor has a load-sensing or constant-flow hydraulic
system, the implement must be equipped with an optional
bypass valve to avoid tractor damage. See “Hydraulic Bypass
Kit” on page 59 for ordering.
