Center/Transport Tires (382 FLOTRUCK):
600/50 R22.5: 58 PSI (400 kPa)
Wing End Wheel Tires:
400/60 R15.5: 52 PSI (358 kPa)
5. Check oil level in the tractor hydraulic reservoir.
Top up as required.
6. Inspect all hydraulic lines, hoses, fittings and
couplers for tightness. Tighten if there are leaks.
Use a clean cloth to wipe any accumulated
dirt from the couplers before connecting to the
tractor’s hydraulic system.
7. Inspect the condition/wear of the discs. If needed
or desired, adjust the Disc Cutting Depth as
outlined in the adjustments section. If excessive
disc wear is evident, replacement may be
required. Refer to maintenance section.
PRE-OPERATION CHECKLIST
It is important for both personal safety and maintaining
good operational condition of the machine that the pre-
operational checklist be followed.

-9-
143433 - PRO-TILL 20|26 (15-January-2021)
Operation
1. Re-phase and cycle oil in the Depth Control Cylinders
(#1) before use. This is especially important after long
periods of storage.
2. Place the Transport Cylinders
(#3) into the FLOAT position
before operation.
IMPORTANT:The Transport
Cylinders MUST be in the FLOAT
position for the PRO-TILL to contour
properly and to avoid possible
cylinder or equipment damage.
IMPORTANT:
The operator
must read and
understand the
tractor manual in order to place the required hydraulic
circuits into float position.
3. Wing Cylinders (#2) Down Pressure:
During operation, the
wing circuit hydraulics
need to be engaged
constantly from the
tractor, in the extended direction. This will ensure
constant down pressure is applied to the wings and
the machine can still contour over uneven terrain
effectively.
IMPORTANT:Operator must read and understand
the tractor manual to place the required hydraulic circuits
into constant pressure position, in the correct direction.
Adjust wing circuit flow down to 20-30% to reduce heat
build-up.
4. IDEAL OPERATING SPEED is 10-12 mph.
Minimum operating speed is 8 mph.
Maximum operating speed is 14 mph.
5. When making headland turns, the operator may
wish to slightly raise the disc sections by activating
the Depth Cylinders (#1). Remember to lower after
coming out of the turn.
6. Each time you start a new field you may need to
adjust the cutting depth depending on the type of
crop residue or soil conditions. The operator can
adjust the cutting depth by following the guidelines in
the “Setting Disc Depth” section.
OPERATING GUIDELINES
7. After making adjustments to the cutting depth it is
recommended to bring the Pro-Till up to speed (10-
12mph) to test the depth setting by driving about
100m (cutting performance changes dramatically
from a slow speed to high speed). Stop, check depth
and cut of field, re-adjust the height higher or lower,
if needed, based on your preference.
Remember: Removing one depth stop lowers cutting
depth 1/2” deeper, Adding one depth stop raises
discs up 1/2” higher.
8. Check/adjust the deflector shield height setting.
9. Harder, packed soil may require additional passes
for optimum results. It is recommended to do a
second pass at an angle to the original pass.

143433 - PRO-TILL 20|26 (15-January-2021)
Operation
NOTE: As the discs wear with usage, the disc depth
settings will also need to be adjusted accordingly.
Use the following as a guideline for setting depth:
1. Drive the PRO-TILL onto level ground. For initial
setup, try "8 Depth Stops"on each cylinder stop.
2. Fully retract the Depth (#1) Cylinders to lower the
frame to ground.
3. Check the penetration depth of the front and rear
row of discs. Measure how much you would like to
raise or lower both the front & rear disc sections
(round to the nearest 1/2” ).
4. Fully raise the frame back off the ground by
extending the Depth (#1) cylinders.
5. For front disc depth, adjust equal number of depth
stops at the LH Rockshaft wheel cylinder & both
Wing gauge wheel cylinders.
For rear disc depth, adjust depth stops on LH
Wing Roller Cylinder.
Lower Discs - Remove 1 Depth Stop for each 1/2”
Raise Discs - Add 1 Depth Stop for each 1/2”
6. Repeat above procedure until proper depth is
achieved.
7. Adjust Fine Pitch if desired (refer to next page).
8. Adjust Dirt Deflector height.
SETTING DISC DEPTH DEPTH SETTING OVERVIEW
Adjusting the disc cutting depth is accomplished by
adding or removing a number of depth-stop spacers
from the adjustable roller and wheel cylinders.
Depth stops limit the stroke distance of the cylinders,
changing the amount that the disc frames are lowered.
Each depth stop that is added to the cylinders raises
the frame height by 1/2”. Therefore, to lower discs
deeper into the soil, you would remove one spacer for
each 1/2” of depth change required.
A typical recommended penetration depth of 2” is
suggested. This depth, however, can be adjusted to the
operators needs and preferences or based on different
crop varieties and soil conditions.
Fast, independent front-to-back pitch adjustment is
achieved by adding or removing depth stops from
rollers (rear adjustment) or wheels (front adjustment).
(Start with 8stops
per cylinder, test
depth & adjust)
(IMPORTANT: Add depth
stops starting from depth plate end )

The main purpose of the Dirt Deflector is to fill the
furrow caused by the right rear disc by capturing, &
containing some of the dirt flow from the right front disc
& redistributing it. The Dirt Deflector can be adjusted
in six directions to enable optimum performance &
operator preference.
To maintain optimum dirt placement while operating
at higher speeds, the entire Dirt Deflector assembly
could be moved rearward. Inversely, for slower speeds,
the entire Dirt Deflector assembly may need to be
moved forward.
The operator may wish to adjust the arm distance
depending on the disc option, frame pitch settings and
soil conditions. For example, if the deflector is plugging
or restricting the flow of dirt and trash, you may wish to
move the deflector arm outward.
When cutting deep, the operator should move the
deflector plate upward to avoid dragging high volumes
of dirt & smearing the ground.
NOTE: You may need to adjust the deflector height
according to soil penetration. Best setting is when
deflector runs just slightly above the ground.

FINE PITCH ADJUSTMENT
Some operators may prefer to adjust the front or rear
frame disc sections to run slightly higher than the other
while using the same number of depth stops.
Fine adjustments to the front to rear disc section height
or "pitch" are done with the threaded pitch adjustment
rods.
NOTE: For better performance, adjust pitch slightly
down (lengthen rod length) to increase roller pressure.
NOTE: Adjust Dirt Deflector "Angle" when the Pitch or
Depth of the Frame is adjusted. If running Nose up or
Nose down, adjust the deflector angle accordingly.
• Shortening adjustment rod length:
- Lowers the Rear Discs
- Reduces Roller Pressure
• Lengthening adjustment rod length:
- Raises the Rear Discs
- Increases Roller Pressure

Operation
Tracking Left Straight Tracking Right
Firm Soil Softer Soil
Tracking is a common occurrence related to how
the front & rear row disc angles respond to varying
degrees of soil hardness. Firm, untilled soil sometimes
causes the machine to slightly track to the left. In
softer soils, or when completing a "second pass", the
machine may tend to track to the right.
NOTE: Sometimes tracking changes in operation
on the same pass due to variable soil conditions.
TRACKING ADJUSTMENTS
Tracking Left Correction:
If you find the machine tracking to the left, you can
adjust the pitch of the unit so the front disc does
less work & the rear disc does more work. This is
achieved by either raising the front row of discs or
lowering the rear row using the independent wheel &
roller depth stops.
Tracking Right Correction:
In soft soil or during a "second pass" the rear row
might overpower the front row causing the Pro-Till
to track to the right. To correct for this and achieve
straight tracking, either the rear discs may need to
be raised or the front discs lowered by adjusting the
number of the depth stops.
Mild tracking, one side or the other may not cause too
much concern, but more pronounced offsets can lead
to larger sub-soil ridges. This results from gaps in the
disc coverage due to the skewed angle of offset discs.

SCRAPER POSITION OVERVIEW
Storage Position
Maintenance Position
Engaged Position
Gap Distance
1/4”-3/8”
Remove the
4 bolts to rotate
into or out of
“Storage position”
then re-install.
Retighten main
bolts or insert a
bolt/pin here to
hold in raised
position.
REVERSING SCRAPER BLADES
Double Sided Scraper Blades
Note: When blades are being
reversed, the complete section must
be changed at the same time or
adjustment will not work properly.
The scraper blades are designed to be
reversible in order to provide extended wear. It
is advised to reorder replacement blades soon
after reversing to prevent possible downtime in
the future.
SCRAPER SIDE-TO-SIDE POSITIONING
Inspect that the scraper plates are
as close to centered as possible
in the roller groove & that no
scrapers are touching the sides
of the rubber roller. (Ideally there
should be a 1/4" gap)
If adjustment is needed, loosen the
scraper arm clamps and adjust position until there is
proper clearance on all edges. You may need to slightly
adjust engagement distance if side-to-side is unsuccessful.
Loosen Clamps to Adjust Side to Side
Needs Adjustment
1/4" Gap Both Sides
Loosen the top bolt to
adjust, then hold in place
while re-tightening.
INDIVIDUAL SCRAPER ARM ADJUSTMENT
The individual scraper arm
position can also be fine
tuned by loosening the top
mounting bolt, adjusting
the position, and then
"holding in place" while
retightening the bolt.
Hole for holding
in maintenance
position.
SETTING SCRAPER POSITION
Change into Storage Position:
• Loosen & remove the 4 bolts (2 per arm).
• Rotate section upward to new position.
• Reinstall bolts and tighten in place.
• Reverse procedure to put into working position.
Change into Maintenance Position (from engaged):
• Loosen the 4 bolts (2 per arm).
• Rotate section upward until top hole is open.
• Tighten bolts to secure and/or
insert bolt or insert pin (user supplied)
into top hole to secure in position.
Change into Engaged Position (from maintenance):
• Loosen the 4 bolts (2 per arm).
• Rotate section down until scraper blades are set
to proper distance from inner roller groove.
(1/4" to 3/8" is the recommended distance)
• Tighten bolts to secure in position.

Troubleshooting - Pro-Till 20/26
Restriction or blocking on right side:
- Raise the deflector plate.
- Move deflector assembly outward.
- Adjust deflector assembly rearward or back.
- Raise machine working depth.
- Reduce operating speed slightly.
- Check condition & operation of disc hubs (make sure
they turn freely).
- Wait for soil conditions to dry out more.
Rear discs or roller not engaging in very
hard soil:
- Adjust pitch so front discs are higher by removing a
depth stop on roller cylinder. (It may be necessary to
lower overall machine depth also).
- Extend gauge wheel ratchet jacks as necessary to
reduce weight on outer front wing corners.
- Momentarily take out of float & extend transport
cylinders to simulate a rigid hitch (flat ground only).
Re-engage float as soon as possible to avoid possible
equipment damage.
Mud not clearing from rubber rollers:
- Check scraper to roller distance & adjust if necessary
(scraper should be 1/4" to 3/8” from roller).
- Check scraper plate wear & adjust or replace as
necessary (replace all scrapers per row at the same time).
- Check scraper row adjustment for slippage &
re-torque or replace hardware if necessary.
Roller plugged in wet conditions:
- Retract transport cylinders to pass over pushed up
mound & smooth out when soil dries.
- Raise discs all the way up & drive 12-14 mph on firm
soil to clear rollers.
- In certain wet soil conditions place scrapers in storage
position to continue operating.
- If plugging persists wait for soil conditions to dry out
even more.
Roller skidding in wet conditions:
- Check scraper operation & settings.
- Raise machine working depth.
- Adjust pitch so front discs are slightly lower by adding
a depth stop to roller cylinder.
- Momentarily take out of float & extend transport
cylinders to simulate a rigid hitch (flat ground only).
Re-engage float as soon as possible to avoid possible
equipment damage.
- Wait for soil conditions to dry out more.
- Check condition & operation of bearings on both ends
of the rollers.
Plugging disc rows in wet conditions:
- Ensure roller is turning & scrapers are set properly.
- Raise machine working depth.
- Increase operating speed slightly.
- Adjust pitch so front discs are slightly higher by
adding 1 depth stop plate to wheel cylinders.
- Fully extend depth control cylinders & hold for 30
seconds to re-phase.
- Check condition & operation of disc hubs (make sure
they turn freely).
- Wait for soil conditions to dry out more.
Leaving a ridge or a groove between rollers:
- Adjust ridge wiper down slightly to remove ridge.
- Adjust ridge wiper up slightly
to eliminate groove.
Leaving a ridge between passes:
- Adjust deflector up to reduce ridge.
- Adjust deflector assembly out to reduce ridge.
- Adjust deflector assembly back to reduce ridge.
- Check that end disc size configuration matches factory
suggested setup.
- Reduce implement width on guidance system for
slightly more overlap.
Tractor oil temperatures are too high:
- Lower the flow on the wing circuit hydraulic remote.
(Typically 20-30%. Refer to Tractor Operators Manual)
