HYDRAULIC SYSTEM

Hydraulic Productivity

The more demanding your application, the greater the
need to properly manage the tractor hydraulic system.
Proper circuit connection, use of the flow control, and
removal of unintended circuit restrictions can improve
hydraulic system performance.
A basic hydraulic circuit consists of:
n
A pump
n
Control valve(s)
n
Hydraulic function
(steering, implement, 3-point hitch, or other).
Larger implements equipped with several lift cylinders
will require more flow to properly lift and lower the
implement. If the flow control is set to deliver the
necessary flow requirement the operator can activate the
circuit and tend to other necessary activities while the
hydraulic circuit completes its cycle.

After connection, operate the circuit and
adjust the flow control dial until the
desired raise/lift time is obtained.

Megaflow Option

The optional megaflow pump adds an additional
hydraulic pump to the system, an additional 29.4 gpm
for a total hydraulic system output of 68 gpm overall.
This is very beneficial when low flow high pressure is
needed at the same time as high flow low pressure.
With the Megaflow option:
n
The Megaflow pump supplies oil to remotes 3, 4, and 5.
n
The standard pump supplies oil to steering, remotes
1 & 2, three-point hitch, and power beyond.

Hydraulic Connection Basics

Hydraulic circuits must be properly connected to
the tractor to operate correctly.
Implement Raise/Lower Cylinders
Implement raise/lower cylinders should be connected
with the remote valve load check in the raise side of the
circuit. If the cylinder is not connected in this way, the
implement will settle while the control valve is in the
neutral position.

Hydraulic Orbital Motors

n
Orbital motors (sprayers, planters, etc.) should be
connected with the motor supply connected to the
lower side of the circuit.
n
Orbital motor supply/return lines should not contain
load checks or other in-line restrictions.
n
The return side of the circuit should be connected
to a motor return port. A motor return connection
minimizes restrictions and improves operating
efficiency in the hydraulic circuit.
