Cultivator be properly assembled, adjusted and
lubricated before use. Illustrations to assist with the
assembly process are provided in Section 2, “Standard
Specifications”. They show proper shank, disc gang
and mounting bracket spacings. Illustrations in this
section show proper assembly procedures. Remove
paint from grease fittings. Replace any grease fittings
that are damaged or missing. Be sure to return screws,
clips, etc., to their original locations.
To insure alignment of assemblies, leave the nuts loose
until completion of final assembly. Use split lock
washers or flat washers as specified. Spread all cotter
pins.
After completion of final assembly, tighten all nuts
evenly to prevent misalignment, distortion or binding.
Tighten all screws and nut s to the recommende d torques
shown in Table 2-1.
Chapter 3
Assembly Instructions
Coulter blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall on to
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Fail ure to stay clear
of disc blade edges can cause serious personal
injury or death.
Do not attempt to lift heavy parts (such as the
frame, disc gangs, rock shaft, and pull hitch)
manually. Use a hoist or a fork lift to move these
parts into position.
To prevent accidental lowering:
1. All hydraulically elevated equipment must be
locked out using the cylind e r lo ck o uts:
2. Lower equipment to the ground while ser vicing
or when it is idle.
Failure to take measures to prevent accidental
lowering may result in serious personal injury or
death.
Be sure to bleed the hydraulic system of all air in
lines after inst allation. Failure to bleed the syst em
of all air can result in permanent equipment
damage.
Never stand under or near the hydraulic folding
wings during folding or unfolding operations. The
wings can drop very quickly resulting in serious
injury or death to anyone under or near the
cultivator wings.
Assembly Preparation
1. Hook up the cultivator to a tractor using the
three-point hitch. Raise the cultivator about 36" and
place stands under the main frame to prevent
accidental lowering.

Decal Placement
Decals are extremely important for naming purposes and
for alerting others to the presence of the machine.
PLACE ALL DECALS on the cultivator as shown in
Figure 3-1 1. Center them as ne ar ly as possible between
the top and bottom on the frame bar. Sometimes, shank
spacing may position a tool frame too near the end of the
frame bar to place a reflective tape square exactly as
shown. Then place the square between the U-bolt s on
the tool frame as near the proper location as possible. A
red reflective square is attached to the rear of the leftand right-hand end tool frames at the factory. If any
decals become unreadable, or are destroyed during use,
get replacement decals from your Landoll dealer as soon
as possible, and replace them on the machine.

CAUTION
Operation and Maintenance
Never allow anyone to ride on the 2000 Series
Row Crop Cultivator at any time. Allowing a
person to ride on the machine can inflict serious
personal injury or death to that person.
Coulter blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall o nto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Neve r pus h
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
All hydraulically elevated equipment must have
cylinder lockouts installed or be lowered to the
ground, when servicing or when equipment is
idle. Failure to take preventive measures against
accidental lowering can result in serious
personal injury.
Never stand under or near the hydraulic folding
wings during folding or unfolding operations. The
wings may drop very quickly resulting in serious
injury or death to anyone under or near the
cultivator wings.
When transporting the unit, place cylinder
lockouts in the transport lock position after fully
extending the cylinders. Insert the lockout pins to
secure the cylinder lockouts. Failure to lockout
the cylinders can cause the unit to settle during
transport, which can result in serious injury or
death and cause damage to the equipment.
When transporting farm implements on public
roads, it is the responsibility of the operator to
abide by state and local laws concerning wide
loads, speed, safety emblems and safety lighting
equipment. Drive at safe speeds. Particularly
when rounding corners, crossing rough ground
or driving on hillsides, to prevent tipping the
tractor.

Tractor Preparation
The 2000 Series Row Crop Cultivator may be used on
tractors equipped with category II or III three-point
hitches with quick couplers. Before attaching the
cultivator, prepare the tractor as follows:
The rear tractor tires should be inflated equally and
ballast added according to the tractor operator’s manual.
1. Install front-end weights as needed on tractor to
maintain stability (See Section 2, “Standard
Specifications” for cultivator weight). Lower the
draft arms, by means of the draft arm control lever
until the draft arm hitch sockets align with the lower
hitch brackets on the cultivator. Place the draft arm
control lever in the least sensitive position. Remove
stabilizer bars or sway blocks during hookup and
operation. Replace after hookup for transporting.
Cultivator Preparation
1. Before operating the cultivator, inspect it to be sure it
is in good operating condition.
2. Replace badly worn or missing parts and any rough
or worn wheel or disc bearings.
3. While the machine is new, bolt tightness should be
checked after a few hours of operation. Tighten any
loose nuts or bolts.
Attaching To Three Point Hitch
1. Carefully back the tractor into place.
2. Attach the cultivator to the tractor draf t arms. Be sure
the hitch pins and sleeves are installed as shown in
Figure 4-1.
3. Reinstall the stabilizer bars or sway blocks before
transporting.

Initial Setup
1. Set the tractor and cultivator on a cement or other
hard, level surface, and check that the top
adjustment link is greased and easy to operate.
2. Lower the cultivator until the swee ps contact the
surface. The gauge wheels should now be ab out two
inches above the surface and the tool frames should
be level with the surface. If not, adjust the top
adjusting link until the tool frames are level, and set
the gauge wheel adjustment (See Figure 3-3) to two
inches above the surface.
3. Raise the cultivator just off the surface. Check for
side to side levelness of the main frame bar with the
tractor rear axle. If necessary, level the frame bar
with the tractor’s draft arm vertical height adjuster.
4. Adjust weeding discs to 1" above swee p at a 15°
angle (See Figure 4-2.)
5. Adjust coulter to 1-1/2” below the sweep.
6. Adjustments for particular field conditions are
described in the following section.

OPERATION AND MAINTENANCE
WARNING
WARNING
Field Operation
1. Remove the stabilizer bars or sway blocks from the
drawbar assembly on the tractor.
2. Pull the cultivator a few feet at the approximate
desired depth and speed you intend to maintain
during use. Adjust the cultivator properly according to
the procedures described in “Gauge Wheel
Adjustment” on page 4-5, “Coulter Adjustment”
on page 4-5, “Disc Adjustment” on page 4-7,
“Disc Bearing Maintenance” on page 4-7, “Tool
Frame” on page 4-8, “Ridgers and Knives” on
page 4-8, “Shields” on page 4-9, and “Lift Assist
Wheel” on page 4-9.
3. Always lift the cultivator completely out of the
ground before turning or backing to prevent
shank, disk, or coulter damage, or damage to their
respective mounting brackets.
4. Reduce speed at field ends, raise the cultivator out
of the ground, and if needed, assist turning by using
the wheel brakes. Do not lower the cultivator into the
ground during turning operations.
5. After a few hours of operation, check all bolts for
tightness. Tighten any loose bolts.
6. When folding wings on wing fold models always
be sure that the wings are out of the ground
before folding. When unfolding the wings, leave
the hydraulic lever in the “EXTEND” position for
a few seconds to lock the wings in operational
position.
7. READ WARNINGS ON THIS PAGE.
8. The Nitrogen accumulator (See Figure 4-9) on the
Lift Wheel Assist provides protection for the hitch
mast and tractor three-point top link, when fully
mounted. It also serves as a cushion to shock loads
when the raised implement is maneuvered. Oil is
transferred from the cylinder to the Nitrogen
accumulator while moving over uneven ground to
relieve excess stress. After moving back to level
ground, pressure build-up within the accumulator
forces oil back into the cylinder. This provides lift
assist, which is preset by the adjustment screw. See
“Lift Assist Wheel” on pa ge 4-9 BEFORE adjusting
this screw.
An escaping hydraulic oil under pressure can
produce enough force to penetrate the skin,
causing serious personal injury. Before applying
pressure to the system, be sure all connections
are tight and that lines, pipes, and hoses are not
damaged. Before disconnecting lines, be sure to
relieve all pressure. Hydraulic oil escaping from a
very small hole can be almost invisible. Use a
piece of cardboard or wood, not your hands, to
search for suspected leaks.
If injured by escaping hydraulic oil, see a doctor
at once. Serious infection or reaction can develop
if proper medical treatment is not administered
immediately.
To avoid personal injury, stay clear of lift assist
wheel and implement during operation. Perform
any adjustments or service on implement when it
is in lowered position.

Gauge Wheel Adjustment
Figure 4-3: Gauge Wheel Adjustment
1. For stability, the gauge wheels must always apply
slight pressure against the soil. Adjust the gauge
wheels by raising or lowering, as needed, to reach
proper depth. To reach proper depth (See Figure
4-3):
a. remove the screw in the gauge wheel shaft
b. make the proper adjustment
c. reinstall the screw
d. tighten the screw and lock nut until the gauge
wheel is securely clamped into position.
2. There are several points to consider when setting the
gauge wheel depth:
a. When the cultivator is in the ground and the
depth is set, the tool frames should tip slightly
forward. This is done by raising or lowering the
gauge wheels and adjusting the tractor top
adjustment link.
b. On very soft or loamy soil, it may be necessary to
set the gauge wheels directly behind the tractor
tires a little different than the others. This allows
their respective sweeps to maintain the same
depth as the other sweeps.
c. The depth should be sufficient to move the
desired amount of soil and to get the sweep into
good, solid soil during high trash situations.

Initial setting for a coulter is at least one inch below the
working depth of the sweeps. Generally, the harder the
soil, the less pressure used on the coulters. To adjust
coulters (See Figure 4-4):
1. Remove the 1/2-13 X 8-1/2 hex head cap screw that
goes through the coulter brace and the to ol fra m e
mount.
2. Raise or lower the entire coulter fork asse mb ly un til
the proper height is reached. Use the lower two holes
in the coulter brace for 18" coulters (standard). Use
the next two holes (above) for the 20" inch coulter
option (See Figure 3-5.)
3. Reinstall the 1/2-13 X 8-1/2 hex head cap screw and
the hex lock nut through the coulter braces and tool
frame mount. Extra holes are also provided on the
lower coulter braces for more adjustment.
The coulters directly behind the tractor tires may
need to be set slightly different than the other
coulters.

Disc Adjustment
Adjust the disc to the proper depth and pitch to create the
desired weeding effect. Discs working at different
settings from each other tend to make the machine fight
itself. Also, discs working too deeply into the soil tend to
throw up excess dirt, resulting in root pruning, which
causes the sweeps to plug. To adjust the discs (See
Figure 4-5):
1. DEPTH - Remove the 1/8 hair pin and clevis pin from
the offset weed disc spindle weldment, and set the
disc assembly to the desired depth. Standard depth
for optimum weeding is 1" to 1-1/2” below the
surface. Reinstall the clevis and hair pins.
2. WIDTH - Loosen the wedge casting in the bottom of
the tool frame. Remove the weeding disc lock pins
from the tool frames and disc brackets. Move the disc
assembly in or out as needed, replace the weeding
disc lock pins, and retighten the wedge casting.
Hammer upward on the head of the 1/2-13 X 8-1/2
hex head cap screw to set the wedge tightly and
replace hex lock nut.
Retighten the wedge casting cap screw several t imes
during the first hour of the machines operation.
3. ANGLE - Remove the clevis and hair pins from the
disc hiller brackets. Adjust the right and left disc
assembly to the same angle. Four angle settings are
allowed at: 11°, 15°, 19°, and 23° (15° nominal).
Replace the pins.
Disc Bearing Maintenance
Check all roller bearings occasionally for excess end
play. To adjust or replace the roller bearings:
1. Place the cultivator frame on blocks or stands just
high enough to lift the tire clear off the ground and
stable enough to prevent tipping.
2. Remove the disc/hub assembly (See Figure 4-5.)
3. Clean and inspect the bearings and hub cavity.
Replace any worn or defective parts.
4. Repack the roller bearings using a high quality
grease.
5. Reassemble the hub assembly, bearing, and seal.
6. Tighten the bearings while rotating the hub until ther e
is a slight resistance to hub rotation. Then, back the
nut off one notch until the hub rotates freely without
end play.
7. Install a new cotter pin and the dust cap.
8. Fill the hub cavity through the grease zerk with
high-quality grease until the grease is forced past the
seal. This will not damage the seal.
9. Wheel bearing maintenance should be done at the
start of every season, and more often when used in
extremely wet soil conditions.

Tool Frame
1. The length of up and down movement for the tool
frame is controlled by the limit chain (See Figure
4-6) on the left side of the tool frame. If a different
distance of movement is required, change the limit
chain one link at a time until the desired amount of
movement is met.
A longer limit chain setting will result in less ground
clearance when the machine is lifted out of the
ground.
Ridgers and Knives
1. Adjust the ridgers or anhydrous ammonia knives
(See Figure 4-7) by loosening the clamp bracket on
the shank, and slide the ridger or knife to th e desire d
depth. Loosen the ridger bracket bolts and slide the
ridgers in or out to the desired width. Retighten the
bracket bolts.

adjustment screws.
Lift Assist Wheel
Adjust the optional lift assist wheel so that when the
machine is in use, the lift assist wheel is lifted clear of the
ground. Raise or lower the lift assist wheel, as needed,
with the adjustment screw on top of the lift assist wheel
frame (See Figure 4-9.)

Tool Hold Down Springs
The hold down springs are on either side of the pa rallel
linkage on the tool frames and are factory adjusted for
most normal conditions. Tighte ning the springs increases
the ground tool pressure. Too much pressure will shorten
the life of the ground tools.
Hydraulic Maintenance
1. Check the tractor hydraulic fluid level per tractor
owners manual and after any leakage. Check fluid
level with the cylinders in the retracted position.
2. If a cylinder leaks, disassemble the parts to
determine the cause of the leak. Any time a cylinder
is opened up, or whenever any seal replacement is
necessary, it is advisable to clean all parts and
replace all seals Seal kits are available from your
Landoll dealer.
3. Check all hydraulic hoses weekly , Look for bind ing or
cracking. Replace all worn or defective parts
immediately.
Lubrication
See Figure 4-10 for lubrications points and
recommended maintenance schedule.
1. The coulter hub bearings, and disc hiller bearings
should be lubricated with a high grade multi-purpose
grease twice a day or every five hours. They should
be filled till the grease is forced past the seals. This
will not damage the seals.
2. The wing fold pins (if applicable) should be greased
daily with a high grade multi-purpose grease.

Storage
The service life of the cultivator will be extended by the
following proper off-season storage practices:
1. Completely clean the unit and inspect the machine
for worn or defective parts. Replace defective and
worn parts, as needed, to avoid delays the following
season.
2. Repaint all areas where the original paint film is worn
off.
3. Grease all exposed metal surfaces of shanks, points,
and coulters.
4. Lubricate as suggested in “Lubrication” on
page 4-10.
5. Store the unit in a shed, or under a tarpaulin, to
protect it from the weather. The ground tools and
tires should rest on a board or other device to keep
them out of the soil.
6. Fully extend the hydraulic gauge wheel cylinders,
and place the cylinder lockouts in the transport lock
position over the cylinder rods. Secure the lockouts
with the lockout pins.
7. Always place the swivel jack on the interior mount
before setting the machine in motion.
