2.7.4 Rear Drawbar Setting
To prepare the rear drawbar for use:
1. Open the tap on the rear drawbar
cylinder.
2. Retract the cylinder and insert pin.
3. Close the tap to secure its position.
To change back to road transport /
'not in use' position:
1. Open the tap on the rear drawbar
cylinder.
2. Remove the pin and stow in the hole
shown.
3. Extend the cylinder and close the tap
to secure its position.
2.7.2 Transporting a UniPress
Behind a Disc Cultivator
With both machines in the transport position
i.e. raised and folded, the chassis of the disc
cultivator should be slightly nose down or
horizontal even when the downward load
from the Simba UniPress is applied to the
drawbar of the disc cultivator. The chassis
should NEVER be tail low in transport as
this will give a high negative loading on the
tractor which could lead to loss of traction
to the rear wheels.
Extreme caution must be taken when
transporting the machine up steep gradients
and across side slopes. Higher drawbar
loading can be achieved by shortening the
drawbar cylinder.
Prior to leaving the field to travel on a public
highway ensure that any clods of soil are
removed from the machine to prevent them
from fouling the road.
MAXIMUM ROAD TRANSPORT SPEED 16
MPH (25 km/h).
2.7.3 Changing from Work
to Road Transport (Simba
UniPress Towed Behind a Disc
Cultivator)
1. Operate the hydraulics to raise the disc
and Simba UniPress.
2. Operate the hydraulics to fold the
wings on both the disc cultivator and
the UniPress.
3. Fit the transport straps to both
machines.
It may be necessary to shorten
the drawbar cylinder of the disc
cultivator until the chassis is
horizontal or slightly nose down
before moving the machines.
Shortening the UniPress drawbar cylinder
will increase the loading on the rear of the
disc cultivator frame. If necessary this can be
used to level the chassis for road transport.
