- This video is going to
demonstrate when and how to set
and adjust the suspension
on the Vermeer 10-series
large trailed mowers.
(upbeat music)
You should consider checking
and adjusting the suspension
on your mower if any of the
following have taken place.
Cutter bar weight increases.
Uneven stubble pattern.
This indicates cutter bars are too light
and have been bouncing over crop.
Strips of bare soil.
This indicates the cutter
bars are too heavy.
Field terrain conditions have changed.
Mower is operated with
a different tractor,
different tire sizes and high heights.
If any suspension system
components have been changed.
First, unfold the cutter bars
and turn the suspension valve
fully counterclockwise to open.
Using your tractor's hydraulics,
raise the cutter bars.
With the suspension valve open,
the cutter bars should lower.
Keep the tractor hydraulics engaged
until the gauge pressure
reading decreases to zero.
Move the tractor hydraulic
control to lower the cutter bar.
The cutter bar should
not raise off the ground
but oil is flowing to
the suspension system
and the gauge pressure
reading will now increase.
Keep the tractor hydraulics
engaged for a few seconds
until the pressure reading on
the gauge stops increasing.
Then, return the tractor hydraulic control
to the neutral position.
Pressure reading on the
gauge should hold steady.
Recommended initial relief
valve adjust is as follows.
Next, close the suspension valve.
You can now operate the mower
and check the cutter bar suspension.
