TOUCH-CONTROL SYSTEM
The working depth will be rnaintained by
rnoving the lever back to the stop each tirne
the equiprnent is lowered.
After attaching the equiprnent to the trac-
tor, the Touch-Control lever front stop rnust
be properly set if there is a possibility of the
equiprnent not clearing the underside of the
tractor. Once the stop is set, the equiprnent
can be raised quickly by a flick forward on the
control lever.
To set the Touch-Control stop, slowly
rnove the control lever forward to raise the
equiprnent and stop it before the equiprnent
hits any part of the under side of the tractor.
Then rnove the stop up against the control
lever and tighten it in this position. This will
prevent the control lever frorn being rnoved
past the point of the desired lifting height.
Note: If the equiprnent hits the under side of
the tractpr, in addition to doing possible darn-
age to the'tractor or equiprnent, the Touch-
Control system will not have completed its
cycle and this will cause the pump unit to oper-
ate at maximum high pressure and heat the IH
Hy-Tran® fluid excessively, thereby causing
possible internal damage to the pump. This
condition can be quickly detected by a notice-
able loading of the engine.
If this condition should occur, immediately
move the control lever back and set the con-
trol lever stop at a point where the raised
equiprnent will not hit the under side of the
tractor.
AIR IN THE SYSTEM
Make certain that all connections and open-
ings are well sealed. The entire system must
be kept tightly sealed_at all times, not only to
prevent loss of fluid but also to avoid entrance
of air in the inlet end of the system. Air enter-
ing the system interferes with proper lubrica-
tion of moving parts. It causes an increased
amount of vibration and an unsteady pressure.
Presence of air in the system will be noticed
by a noise in the pump or by the pump laboring
when operating under high pressure. Proper
filling of the reservoir and working the system
during the filling process, will work the air
out of the system.
Freeing the System of Trapped AJr
Start the tractor engine and operate it at a
moderate idle speed. With the filler plug re-
moved, move the Touch-Control lever or
levers back and forth 10 to 12 times through its
full range of travel. This quickly frees the sys-
tem of trapped air. Then with the control lever
in the rearward position (toward tractor...seat),
th
·
~)
stop e engIne.
If necessary, add sufficient clean fluid to
the reservoJ-r to bring the iluid level to within
1/2-inch of the bottom of the filler opening.
Replace and tighten the filler plug.
FAST-HITCH
Touch-Control raises and lowers the com-
plete hitch, thus raising the equipment to the
transport position, or lowering it to the work-
ing position.
The leveling crank at the rear of the tractor
controls leveling, and the depth adjusting crank
on the right side controls depth adjustment.,
When operating the hitch in other than the
fixed drawbar position, the belt pulley must be
removed. The belt pulley shaft must be cov-
ered with the belt pulley shaft guard and the
power take-off shaft must be covered with the
power take-off shaft guard, if not already so
protected.

Note: The following operating and adjusting
instructions are general only. Refer to the imple-
ment Operator's Manual for specific instrUctions.
The Touch-Control hand lever serves to
control the raising and lowering of equipment.
Do not attempt to gauge the depth with this
lever unless so instructed in the equipment
manual. Plows must be free to float up and
down and to seek their own level as determined
by the hitch setting. The depth adjusting crank
(lIIusts.
15
and
16) serves to control the working
depth of plows and various other equiprnent.
The leveling crank controls leveling as required
for plowing when opening up a furrow or for a
change in plowing depth. The diagonal link
permits the plow to swing from side to side,
when the lock bolt is loose so the diagonal link
is free to swing.
