SAFETY PRECAUTIONS
All machinery is inherently dangerous to children and persons unfamiliar with its general
operation. Lorenz Manufacturing Company strongly recommends that no person without a
thorough understanding of how the Lorenz Row Crop Cultivator operates be permitted to
operate the machine. The machine should be operated only by responsible persons who
have read the operators manual, and are informed about the machine’s use and are
delegated to do so.
Prior to operating the Row Crop Cultivator, be sure to read and understand this Operator’s
Manual. If there is any portion you do not understand, or any phase of the machine’s
operation you do not understand, be sure to contact your local Lorenz dealer or Lorenz
Manufacturing Company.
Shields and other safety features are built into the machine whenever possible; however,
investigation of many accidents show that careless use of machinery causes a high
percentage of accidents. You can avoid many accidents by observing the rules for safety
given here. Study the rules carefully and insist that they be followed by yourself and those
working with you and for you.
SAFETY RULES
Use adequate front tractor weights to provide safe steering and to prevent upset when
transporting the cultivator.
When the cultivator is attached to the tractor, at road speeds, use extreme caution and
avoid hard applications of the tractor brakes at high speeds. When descending steep
grades, select a sufficiently low gear to maintain control with minimum braking.
Reduce speed before turning quickly or applying brakes. Couple the brake pedals together
when traveling at high speeds. Brake both pedals simultaneously when making an
emergency stop. Always drive slowly over rough ground. Drive at speeds slow enough to
insure your safety.
Always keep the tractor in gear when going down steep hills or grades.
Whenever the tractor is stopped, place the transmission in the park position or lock the
tractor brakes before dismounting.
Be careful to prevent the tractor from tipping sideways if it strikes a hole, ditch, or other
irregularity, especially when operating on hillsides.
When driving out of a ditch, gully, or up a steep hillside, engage the clutch slowly. Be
prepared to disengage the clutch promptly should the front wheels rise off of the ground.
5
Observe the same precautions if the rear wheels become mired in soft ground or drop in a
hole.
Do not drive near the edge of a ditch or gully.
Only one person, the operator, should be permitted on the tractor when it is in operation.
Never allow a person to ride on the cultivator.
When driving on public roads and highways:
a. Do not drive after dark.
b. Use a slow-moving vehicle emblem.
Before working on the cultivator, shut off the tractor, set the parking brake, relieve
pressure on the hydraulic lines and disconnect hydraulic lines from the tractor.
Don’t work under the machine when it is in the raised or folded position.
Never make any adjustments or lubricate the machine with the tractor running or with
someone on the tractor.
In the event the cultivator is a folding wing type, make sure no one is close to the machine
when the wings are lowered.
On folding wing models, be sure the wings are locked in the transport position before over-
the-road hauling.
PREOPERATING CHECKLIST
Before operating the cultivator, follow these instructions:
1. Read and have a thorough understanding of the Operator’s Manual, especially the
section pertaining to machine operation and safety.
2. Be sure anyone who will assist you in the operation of this machine knows how the
machine operates.
3. Know the machine’s safety features and understand the safety pointers.
4. Be sure the machine is hitched properly to the tractor.
5. Be sure all lubrication points have been lubricated.
6. Give the machine a “once over” for any loose bolts.
7. Check optional gauge wheel tire pressure.
8. Check hydraulic connect of cultivator to hydraulic controls.
a. Connect hoses from frame to one separately controlled valve.
9. Connect machine to tractor and perform the following operating checks:
a. Raise and lower wings to insure full travel and correct operation.

FIELD OPERATION
The C-Shanks are fastened to the gang toolbars by means of a spring-loaded C-Shank
assembly. The special C-Shank assembly locks, fastened on both sides, secure the
assembly in position and reduces side-to-side movement of the C-Shank assembly. It is
very important that the main assembly bolt and the lock U-bolts remain tight.
Over the years, it has been shown that breakage of tines usually occurs when the tines
have run while loose on the toolbar. We, therefore, strongly emphasize to check and
retighten the bolts after two to three hours use.
Proper mounting of the cultivator onto the tractor is important to cultivator operation.
Remembered that the self-levelling device levels the cultivator from front to rear, and this
together with the top link arm, will enable you to adjust the cultivator so that all of the
tines front to rear will work at the same depth.
For example, if extra horsepower is needed, the front end is working deeper than the rear
row or vice versa. It is, of course, also important that the tractor’s lift arms are adjusted so
that the cultivator is level from side to side, as well as from front to rear. In order to get
the cultivator to work level, it is important that the A frame is perpendicular to the ground
when the cultivator is working. To provide for a more aggressive cultivator dig, tip the
cultivator back a little by extending the upper 3-point link arm.
ROW CROP CULTIVATOR ASSEMBLY INSTRUCTIONS
1. See Fig. 1. Position the main beam of the cultivator on two appropriate objects for
easy assembly (sawhorses work very well). The wide face of the beam should be
resting on the objects used to position the beam.
2. Mark for cultivator gang placement.
a. Locate and mark the center of the beam. This will serve as your standard
guide.
b. If 30-inch rows are the desired spacing, mark off every 30 inches to each
side of the center mark.

3. 5”x 7” Head tower assembly. See Fig. 2a. Position the head tower (6) at the
center of the toolbar with hitch holes to the front. Wrap the two ¾” U-Bolts (5)
from the bottom of the toolbar and insert through the head tower holes. Fasten
with ¾” lock washers (3), and ¾” hex nuts (4).
Insert the upper 3-point 1”x 4” Pin (13) in the top holes of the head tower. Secure
with a 3/16” hairpin.
Fig. 2a
5”x 7” lower 3-pt. hitch assembly. Mark equal distances from the center of the
toolbar on each side of the head tower of 16 inches for category 2 hitches, or 19
inches for category 3 hitches. Align the inner edge of the lower 3-pt. hitch
components (2), with hitch holes to the front, to these marks. Insert one ¾”x 9”
bolt (14) through the holes above the toolbar of each component, and fasten with
¾” lock washers (12) and ¾” hex nuts (8).
8
Insert the two lower 3-point 1 1/8”x 5” pins (12) for category 2 hitches, or 1 7/16” x
6 ¾” pins for category 3 hitches, in the holes of the lower 3-pt. hitch. Secure with
3/16” hairpins.
4. 7”x 7” Head tower assembly. See Fig. 2b. For both folding and non-folding
toolbars, position the head tower (136) at the center of the toolbar with hitch holes
to the front. Insert two ¾”x 9” bolts (133) through the holes below the toolbar and
fasten with ¾” lock washers (76) and ¾” hex nuts (7).
Insert the upper 3-pt 1”x 4” pin for category 2, or 1 ¼”x 4” pin for category 3.
Secure with a 3/16” hairpin.
Fig. 2b
7”x 7” lower 3-pt. hitch assembly. Mark equal distances from the center of the
toolbar on each side of the head tower of 18 ¼ inches for category 2 hitches, or 21
inches for category 3 hitches. Center the lower 3-pt. hitch components (135), with
hitch holes to the front, on each of these marks. Insert two ¾”x 9” bolts (133)
through the holes above the toolbar of each component, and fasten with ¾” lock
washers (76) and ¾” hex nuts (7).
Insert the two lower 3-point 1 1/8”x 6” pins for category 2 hitches, or 1 7/16” x 6 ¾”
pins for category 3 hitches, in the holes of the lower 3-pt. hitch. Secure with 3/16”
hairpins.
5. Mounting the parking stand. Mount the parking stand next to the 3-point head
tower. Fasten the stand to the toolbar with the two 5/8” U-Bolts, 5/8” hex nuts, and
5/8” lock washers. Folding wing models have two parking stands, which mount
near the hinges.
9
Note: If the parking stand makes contact with the tractor cab when the cultivator is
raised, reposition the parking stand on the rear side of the toolbar.
6. See Fig. 5. For 5-Shank gangs, place the two front adjustable tubes (19) or (20)
into the front Formed angle of the gang. Insert the ½” L-shaped bolt (22) around
the tubes and through the appropriate holes in the gang. When placing the
adjustable tubes (19) or (20), make sure that the flanged side of the tube is at the
outer edge of the gang, and turned up to prevent the loss of the tine, should the
tine clamp bolt work loose. Adjust the front tubes according to the desired row
width and secure the L- shaped bolts with lock washer and nut (5) and (6). See
Fig. 3.
Note: When modifying cultivators from a wide to a narrow, such as 4 Row Wide to 4 Row
Narrow, 6 Row Wide to 6 Row Narrow, or 8 Row Wide to 8 Row Narrow, the front square
tubes must be shortened from 19” to 15” on all gangs.
