Problem
VRT Hydraulic Drive System`
1. Hydraulic spinners do not operate when
engaged on screen.
Possible Solution

Check that the tractors hydraulics are
engaged.

Check that the quick release tips are
plugged into the correct remote & that
flow is in the right direction. Red band on
hose end indicates pressure hose. Each
hose should be labelled with ‘Spinner’ &
‘Feed Chain’ to ensure correct connection
to tractor remotes.

Use the manual override valve on the
manifold to confirm hydraulic flow is
getting to the spreader (refer page 9).

Check that the Unipod (ECU) on the
spreader has power. There will normally
be a light on the ECU itself or you may
need to use a multimeter.
2. Feed Chain does not engage

Check that all of the values are set in the
monitor to allow the feed chain to run.

Check that the hydraulics on the tractor
are engaged and that the couplings are
attached correctly to the remotes.

Check that you have a ground speed
reading on the screen of the spreader
control monitor.

Use the manual override valve on the
manifold to confirm hydraulic flow is
getting to the spreader (refer page 9).
3. Cannot achieve set spinner speed or
application rate on screen

Check Hydraulic setting on tractor. It may
be necessary to increase the flow rate of
a particular remote bank to meet the
demand.

Application rate may be too high or door
setting too low for the particular product
being spread. Check rate by slowing the
ground speed down. If the rate
increases, it may be necessary to make
a rear door adjustment or narrow the
spread width by slowing down the
spinners.

Check all operator inputs in the monitor
to make sure all are correct.
