Setting Flow Control Valve
This procedure is for those units with the solenoid valve
option, on RCP 2560 and RCPM2560.
The flow control valve diverts excess oil back to the
tractor, which in turn keeps the back pressure down and
keeps the oil cooler.
1.
Time the 2nd arm cylinder (arm furthest from the
tractor) from the fully extended position, to the fully
retracted position.
2.
Set the turtle/rabbit control on the tractor, or the flow
control valve (optional), so that the cylinder cycles at
5 seconds.
3.
These cylinders require 5 GPM (gallons per minute)
for proper arm function. Timing of the cylinder is the
easiest way to set the GPM.
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.
IMPORTANT:
Overheating of the oil may occur if the flow
control kit is not installed. Damage to the o-ring in the
solenoid valve and/or the cylinders may occur if the oil
becomes overheated
.
Timing Procedures
Refer to Figure 2-12:
1.
Set the RCP2560 in the transport position with the
arms and deck in the folded position.
2.
Retract the 2nd cylinder which will raise the 2nd
arms up. Time this sequence. Time should be 5
seconds.
3.
Adjust the turtle/rabbit control or the flow control
valve until the cycle time is 5 seconds.
4.
The unit is now set for proper operation.
If the unit is having overheating problems through the
hydraulics, check the tractor’s operator’s manual for
power beyond hook-up.
