Lock the push-bar with the thread locking pin. Fig. 13 shows the equivalent hydraulic push-bar
measurements.

Connecting hydraulics
Standard JC hydraulic equipment is connected to a hydraulic outlet intended for external single-
function cylinders. Bar cylinders supplied as optional equipment require a second single-function
outlet.
If the seed drill is installed with dual-function lift cylinder equipped markers, the two hoses running
from machine are connected to the tractor’s dual-function outlet. Similarly, the hydraulic push-bar of
a multi-function tow-bar (optional) is dual-function, and therefore requires another 2-function outlet.
NOTE!
When connecting hydraulic connectors, the tractor’s hydraulic PTO control gear must
be in the lowering or floating position to ease the connection.
WARNING!
When connecting hydraulic lines to the tractor, ensure that the machine, tow-bar or
markers cannot lower uncontrollably and thus harm adjacent people or other objects!
Connect the tow-bar to the tow-point before connecting the hydraulics.
NOTE!
Certain tractor models require the use of non-standard hydraulic quick-change
connectors recommended by the tractor manufacturer. Replace the relevant components with
suitable components as required on your tractor in order to ensure proper hydraulic function.
