Operation
Implement Flex
The implement on your drill is equipped with either
full flex or limited flex. The difference between full flex
and limited flex is different planting width and
different row spacing at the hinge.
Full flex
- allows more down travel at the pivot
without crashing the openers, but pushes the
openers apart at the pivot which ends up with a wider
planting width to have enough clearance.
Limited flex
- holds the row spacing steady and the
planting width at a true 6.0 meters. The wings pivot
downward very little to prevent the openers from
hitting each other.
Brake Operation
Know Your Tractor Systems
Applying tractor parking and/or emergency
brakes may or may not
operate the drill
service brake system, depending on the
design of the tractor systems.
The service, or trailer, brake system is controlled by
the brake system on the tractor. The drill brake
system consists of main cart wheel brakes and a
hand brake. There are brake shoe pairs on each of
the main cart wheels.
On drills with hydraulic brakes, the brakes are
spring-released. Drill braking is released shortly after
unhitching the drill.
On drills with air brakes, the brakes are
spring-released. The air brakes may not be applied
when the air lines are disconnected. If there is not
enough air pressure in the air reservoir, the drill
brakes will be released by spring pressure. If there is
enough air pressure in the air reservoir, the brakes
will be applied.
See your tractor operator manual for details on when
remote brake ports are engaged and released. Note
any difference of function in the table below. The
tractor operator must know when drill brakes are
engaged and released.
