Farm Star T55-74 - Manual (Page 27)

A S S E M B LY (continued)
Refer to the Safety Precautions and Warnings on the
front cover and in the Safety Section of this manual prior
to working on the machine.
Assemble the top hitch “A” frame parts. Refer to the
correct “exploded view” drawing in the back section of
this manual for proper part position. It is suggested that
all the parts be assembled with the bolts loose until all
parts are together and then go back and tighten all bolts.
On the T40 and T55 Series Models, assemble the two
lower hitch pull brackets. Position these with each
bracket 13 inches from the center of the machine to the
inside of the pull bracket. (Category I hitch lift arms
should be 26 inches apart.)
On the T40 and T55 Series Models, if you have pur-
chased the optional parking stand, it is suggested that
you install it at this time to make it easier to work on the
machine. Make sure it will not interfere with the pull
bracket or with the removal or insertion of the pull pin.
Do NOT assemble the PTO driveline at this time.
– Start the tractor engine and lift the machine from the
ground about 12-14 inches. Now switch off the tractor
engine.
– Install the lift arm stabilizer arms or anti-sway blocks
or anti-sway chains (depending on tractor make and
model) to limit side sway of hitch. (Note: side to side
oscillation of about 2 inches is recommended, but not
more.)
– Level the machine at the sides by adjusting the tractor
lift links.
– Mount the driveline, checking that it correctly meshes
at both ends.
– Check that the driveline is the correct length Figure 2.
The knives must be at the same distance from the
ground on both sides of the implement.
The minimum coupling length (overlap) must be no less
than 180 mm (6 inches) in each work position.
Driveline travel must still be about 25 mm (1 inch) in the
maximum coupling (overlap) position. See Figure 2.
Always couple the two end forks of the driveline and
check that they are perfectly locked in place.
To achieve this condition, completely insert the latch
pins and safety bolts Ref. #1 Figure 2 into the relative
grooves in the PTO shafts on both the tractor and
machine shafts.
An unlocked shaft would slip out of position, causing
notable mechanical damage and serious injury to anyone
near.
If the driveline is too long, it should be shortened in the
following way:
– Set the machine PTO input gearbox shaft at a mini-
mum distance from the tractor PTO stub shaft; then
brake the tractor and switch the engine off.
– Separate the two halves of the driveline. Install the
female part into the tractor PTO and the male part on
the machine PTO, checking that the position is correct
by means of the latch pin or locking bolts (clutch
models).
1. When using tractors with multi-speed PTO, be certain
PTO is set for 540 rpm.
2. Back tractor up to tiller until lower 3-point links are
aligned with hitch clevises on tiller. Always stop the
tractor, set the brake, shut off the tractor engine, and
remove the tractor key, before dismounting tractor.
3. Secure the tractor’s 3-point lower links to the lower
hitch clevises using 7 / 8 ” diameter hitch pins.
4. Secure the tractor’s top link to the tiller top hitch using
a 3 / 4 ” diameter hitch pin (supplied by customer). Adjust
tractor top link in order to level the tiller.
5. Adjust the tractor’s 3-point hitch lift height so that the
tiller tines are not lifted more than 14 inches off the
ground to prevent damage to the driveline u-joints.
TRACTOR HOOK-UP

Gearbox overheating. 1. Low on lubricant.
2. Improper type lubricant.
3. Excessive trash build-up around gearbox.
Fill to proper level.
Replace with proper lubricant.
Remove trash.
Soil texture too coarse. 1. Ground speed too fast.
2. Leveling door too high.
3. PTO speed too slow.
4. Soil too wet.
Decrease ground speed.
Lower leveling door.
Increase PTO speed.
Wait until soil dries.
Soil texture too fine. 1. Ground speed too low.
2. Leveling door too low.
3. Shallow working depth.
Increase ground speed.
Raise leveling door.
Increase the depth by means of the
skids.
Tiller skips or leaves
crop residue. 1. Badly worn or bent tines.
2. Ground speed to fast for conditions.
3. Slip clutch slipping (if unit so equipped).
Replace worn/bent tines.
Reduce ground speed.
Reduce load.
Overheated side
supports. 1. Grass/soil build-up on ends of rotor.
2. No lubrication on side support or
side transmission.
Clean rotor.
Check oil in chaindrive box and
lubricate outer side bearing.
Tines balling up with
soil. 1. Worn or bent tines.
2. Tines incorrectly installed.
3. Rear leveling door too low.
4. Tractor speed too fast.
5. Soil too wet.
Replace tines.
Install correctly.
Raise door.

Wait until soil dries.
Work depth differs on
the two side of the tiller. 1. Side skids set at different height. Adjust skids to same height.
Tines clog frequently. 1. Soil too wet.
2. Excessive forward speed.
3. Grass/weeds too tall to be worked.
Wait until soil dries.
Reduce ground speed.
Cut grass/weeds beforehand.
