The tractor’s turtle/rabbit flow control valves are used
when all hydraulic connections are connected directly to
the tractor outlets.

and the turtle/rabbit flow control valves have been set
correctly, then check tractor operator’s manual for power

NOTE: Parallel Arm Cutters with (S/N 163695-) will
require flow control valve kit #316-068K if your
tractor does not have flow control (turtle/rabbit
control) or if your tractor uses an open center
hydraulic system. Check your tractor’s operator’s
manual to determine your tractor’s set-up.

Hydraulic Flow Control Settings
The hydraulic cylinders require 5 GPM (gallons per
minute) to function properly. This is set by adjusting the
flow control valve(s) and then timing how long it takes for
the cylinder to fully retract. The valve is adjusted
correctly when it takes 5 seconds to retract.

Cutter Flow Control
Refer to Figure 2-1:
An auxiliary flow control valve is included with the cutter
when provided with solenoid controlled cylinders. The
flow control valve diverts excess oil back to the tractor
keeping oil cooler and back pressure down.
