Sowing Depth Control
The sowing depth is dependent on:
1 The wheel height in relation to the chassis
2 Tyre pressure
3 Ground condition i.e. hard or soft
The wheel height in relation to the chassis is controlled using
the hydraulic ram depth stop. With the machine raised up,
adjust the position of the depth stop.
Transport Position
It is recommended to raise the drill into the transport
position when turning at headlands to avoid damage to the
ground engaging components.
Wing Pressure Setting
This is used to keep down pressure onto the wings for
even sowing depth across the tool bars: this transfers the
centre frame weight to the wings in hard conditions.
The wing hold switch must not be activated when the
wings are folded ie when the machine is in transport.
The switch may only be activated when in the drilling
position.
All conditions are different so the wing pressure can easily
be adjusted to the desired setting by using the gauge on
the machine. When the switch is activated, the oil in the
wing rams is held in this hydraulic circuit under pressure
and can’t return to the tractor. Expelled oil from the rams is
taken up by the accumulator.
When the tractor remote is postioned into the float position
it allows oil in the hoses to flow back into the tractor. On
heavily undulating ground and in some other conditions a
(factory set) safety pressure relief valve is automatically
triggered; this protects the machine from damage.
When this safety feature is triggered, the wing pressure
setting will need to be reset.
How to set the wing pressure:
1. Position the pressure switch to ON (in-cab console).
2. Using your tractor remote lever, power up the hydraulic
system to the desired level using the gauge on the
machine as a guide.
3. Move the tractor hydraulics into the float position for this
function. -the system is now set.
