Pickup Speed Adjustment – Closed
Center Systems
The tine speed is adjustable in series with
the belt speed by adjusting hydraulic oil
flow.
IMPORTANT:
For closed-center hydraulic-type tractors,
always leave the hand valves of the merger
manifold completely open (turned out fully).
See Figure 17.
For closed-center tractors, adjust the flow of
the tractor to control the pickup speed.
To set the maximum speed, first, start with a
slow oil flow and increase the hydraulic
flow slowly until the pickup speed no longer
increases or a pulse develops in the pickup
speed, whichever occurs first. Then
decrease the hydraulic flow slightly to make
sure that oil is not pushing over relief in the
tractor.
To set a slower speed, decrease the tractor
oil flow.
IMPORTANT:
It is important to limit the tractor output to
less than 12 GPM to avoid pushing oil over
the relief in the tractor which can cause the
tractor hydraulic system to overheat. The
manifold on the merger protects the motors
from over speed, but not from overheating.
IMPORTANT:
Depending on tractor make and model,
engine speed can impact the hydraulic oil
flow to the merger during this process.
Always set the tractor engine rpm to desired
operating speed before setting merger
hydraulic speeds.
Note: A new manifold is used starting with
serial number RCIX00835. Units built prior
to this serial number break do not feature the
ability to switch between open-center and
closed-center tractors and do not have flow
control built into the manifold. For units
with earlier serial numbers, the belt motor
circuit is equipped with a fuse to prevent
over speed and implement damage. If
hydraulic flow exceeds 11 gpm (42 lpm), the
fuse will trip. To reset the fuse, release all
hydraulic pressure on the motor circuit
through the float position of the tractor
hydraulic function. Resume operation once
reset.
