Warning
Before operating any of the controls
ensure that all pedestrians are clear of
the tractor and its implements.
Note
The controls illustrated are those for
footstep tractors, these are illustrated
for convenience, the cab controls being
identical in position and operation.
The ITMCO hydraulic system combines
the tractor and implement into one unit
with the implement hydraulically con-
trolled. This system provides these five
functions:
1. Draft control, (3 Figs. 6 and 7) is used
to control the working depth of soil en-
gaging implements.
2. Position control, (2 Figs. 6 and 7) is
used to control the working height of
implements above the ground.
3. Response control. (1 Figs. 6 and 7) is
used to control the speed of drop of
the lower links and the attached im-
plement.

4. Auxiliary hydraulics are used for the
control of external equipment that
require hydraulic power for their op-
eration, such as trailer tipping, loader
operation, hydraulic motor drive, etc.
5. Selector control, (4 Figs. 6 and 7) this
control selects and diverts the flow of
hydraulic oil from the linkage pump to
either the internal lift system or the
auxiliary hydraulic control valve.
