Transport
1
Raise the drill into the transport position and hold at the full
extent of the rams for a few seconds to allow cylinders to
rephase/equalise.
2
Important - To avoid machine damage due to drill
lowering during transport, always close the hydraulic valve
on the drawbar. Move the handle to a position at 90
0
to the
hydraulic line. This applies to the drawbar and disc opener
hydraulic valves where fitted.
3
Locate jack stand in transport position, if fitted.
4
Ensure lighting and oversize warning requirements meet
recommendations published by the local Land Transport
Authority or equivalent.
5
Maximum towing speed 40 km/hr
.
For countries other than New Zealand other speed
restrictions may apply, please refer to your local
transport authority.
Ensure towing vehicle requirements are adequate
for the towed vehicle e.g. mass, brakes. Refer to
recommendations published by the local Land Transport
Authority or equivalent.
Braking when towing can cause the load to jackknife. Use
extra care when towing in adverse conditions such as mud,
inclines and sharp bends.
Lower towing speeds are recommmended on farm roads/
tracks and where one wheel is on or over a road verge.
6
Attach safety chains to tractor.
Refer Fig 3.
Safety chains must be crossed over underneath the
coupling and attached to the towing vehicle. The
attachment points must be as close as practical to the
towing coupling and one each side.The towbar on the
towing vehicle must be rated for the towed mass.
Do not
remove or replace the safety chains provided with any
other than those specified in the parts manual.
Note:
The safety chains are provided with sufficient
length to cater for all towing vehicles. Safety chains must
be shortened by cutting off excess length so that if the
coupling fails the drawbar will not hit the ground.
7
If the machine is fitted with row markers or other vertical
extensions, check clearance under power lines en route.
8 Important -
For greater disc opener ground clearance,
adjust the ram or turnbuckle on the disc opener unit so
they are at maximum height, and/or extend the drawbar
ram or turnbuckle to level the machine chassis.
