Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
▲ Do not exceed 20 mph. Never travel at a
speed which does not allow adequate control
of steering and stopping. Reduce speed if
towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the weight
of towing vehicle.
▲ Carry reflectors or flags to mark implement in
case of breakdown on the road.
▲ Keep clear of overhead power lines and other
obstructions when transporting.

This section covers general operating procedures. Experience, machine familiarity and the
following inf ormation will lead to efficient operation and good working habits. Always operate
farm machinery with safety in mind.
Prestart Checklist
Escaping fluid under pressur e can have sufficient pr essure to penetrate the skin. Check all hydraulic lines
and fittings before applying pressure. Fluid escaping
from a very small hole can be almost in visible. Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.

DANGER
Y ou may be sever ely injur ed or killed by being crushed
between the tractor and implement. Do not stand or
place any part of your body between implement and
moving tractor. Stop tractor engine and set park brake
before installing hitch pin.
The leveling links and depth indicator linkages f or
both the tillage depth and coulter depth are interactive. Each step in these field adjustments relies
on the previous step being done correctly. Complete the following steps in the order listed.
Leveling the Implement
1. While pulling forward in a le vel field, lo wer the
V erti-Till to a depth of around 8” to 10”. The
depth you choose is not critical at this point.
Refer to Figure 13
2. Stop the tractor with the Verti-Till in the
ground and check the frame f or level. The two
main frame tubes running the length of the
unit should be parallel to the ground.
a. If the frame is high in front, loosen the jam
nut and shorten the turnbuckle on the
tongue. Secure the jam nut.
b. If the frame is low in front, loosen the jam
nut and lengthen the turnbuckle on the
tongue. Secure the jam nut.
Note: Repeat step 2 as needed until implement is
level.
Setting the Tillage Depth Indicator Gage
1. Pull the Verti-Till forward in the field and fully
lower the unit (16”). In hard conditions you
may hav e to till a small area twice to be able to
pull the unit at full depth.

Refer to Figure 15
3. To adjust this reading, loosen the two bolts
joining the tip depth link and lengthen or shorten as needed. Retighten and check the setting
from the tractor seat.
Note: The tip depth link has two notches that can
be aligned with each other and used as a starting
point when adjusting the length of this link.
Once set, the tip depth indicator will show actual
tip depth and is very accurate through a range of 6”
to 16”.
Before moving on to the ne xt step , the unit can be
raised from the full 16” depth. The depth you chose
in not critical, but should be at least 6” deep.
Setting the Coulter Depth Indicator Gage
1. Adjust the cutting depth of the coulters to
about 2” or 3” while traveling through the field.
Stop the tractor and dig to find the bottom of
several coulters . Measure or estimate an average cutting depth.

Refer to Figure 16
2. Observe from the tractor seat the coulter
depth pointer. Adjust the coulter depth linkage
until the indicator reads the same depth you
averaged in step 1 abo ve.
Refer to Figure 17
3. To adjust the coulter depth pointer, loosen the
two bolts joining the coulter depth link and
lengthen or shorten as needed. Retighten and
check the setting from the tractor seat.
Note: The coulter depth link has two notches that
can be aligned with each other and used as a starting point when adjusting the length of this link.
Once set, the coulter depth indicator will show actual coulter depth and is very accurate through a
range of 1” to 4”.
Note: As the coulter blades wear you will not be
cutting the same depth as with a new 20” blade.
The coulter depth linkage can be adjusted periodically as the blade wears so it will continue to report an accurate cutting depth.

1. Raise the implement fully and install the cylinder locks, see “Lock Cylinders ,” page 28. Pull
the spring loaded pin (1) and slide the moveable depth stop (2) to achiev e desired tillage
height and re-engage pin. The top hole allows
for a 16” tilling depth and the lower hole allo ws
for a 6” tilling depth. Repeat for opposite wheel
arm.
NOTE: Be sure the lock pins are set in the same
holes on both wheel arms.
2. Adjust the coulters up or down to achieve different tilling, cutting and mixing results. A pilot
operated check valv e in the coulter lift circuit
will lock the coulters at the depth you choose.
3. Always lift the unit out of the g round when turning at field ends and other short radius turns to
avoid damage and premature wear to the
shanks and coulter gangs.
4. Both the Auto reset and Rigid shank mounts
are protected by shear bolts for e xtreme overloads. If the shank bolt shears replace the lower bolt with the correct shear bolt, use GP part
number 802-060C. (HHCS 5/8-11 x 4 Gr5)
Note: For your con venience a series of holes in 4
gussets on the rear of the machine have been provided for spare shear bolt storage.
