General Hazard Information
No accident-prevention program can be successful without the wholehearted cooperation of
the person who is directly responsible for the operation of the equipment.
A large number of accidents can be prevented only by the operator anticipating the result
before the accident is caused and doing something about it. No power-driven equipment,
whether it be transportation or processing, whether it be on the highway, in the field, or in
the industrial plant, can be safer than the person who is at the controls. If accidents are
to be prevented--and they can be prevented--it will be done by the operators who accept
the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will
help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, “the best kind of a safety device is a careful operator.” We, at Unverferth
Mfg. Co., Inc. ask that you be that kind of operator.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!

• Read and understand this operator’s manual before operating.
• All machinery should be operated only by trained and authorized personnel.
• To prevent machine damage, use only attachments and service parts approved by the manufacturer.
• Always shut towing vehicle engine off and remove key before servicing.
• Avoid personal attire such as loose fitting clothing, shoestrings, drawstrings, pants cuffs, long hair,
etc., that may become entangled in moving parts.
• Do not allow anyone to ride on the implement. Make sure everyone is clear before
operating machine or towing vehicle.
• Never attempt to operate implement unless you are in driver's seat.
Following Safety Instructions
• Avoid working under an implement; however, if it becomes absolutely unavoidable,
make sure the implement is safely blocked.
• Ensure that all applicable safety decals are installed and legible.
• When working around the implement, be careful not to be cut by sharp edges.
• Explosive separation of a tire and rim can cause serious injury or death. Only properly trained
personnel should attempt to service a tire and wheel assembly.
• Add sufficient ballast to tractor to maintain steering and braking control at all times. Do not exceed
tractor’s lift capacity or ballast capacity.
Before Servicing

FIELD CULTIVATORS — Safety
1-5
• Regulate speed to field conditions. Maintain complete control at all times.
• Never service or lubricate equipment when in operation.
• Keep away from overhead power lines. Electrical shock can cause serious injury or death.
• Use extreme care when operating close to ditches, fences, or on hillsides.
• Do not leave towing vehicle unattended with engine running.
During Operation
• Check for proper function of all available transport lights. Make sure that all reflectors are clean and
in place on machine. Make sure the SMV emblem is visible to approaching traffic.
Before Transporting
• Do not stand between towing vehicle and implement during hitching.
• Always make certain everyone and everything is clear of the machine before beginning operation.
• Verify that all safety shields are in place and properly secured.
• Ensure that all applicable safety decals are installed and legible.
• When working around the implement, be careful not to be cut by sharp edges.
• Add sufficient ballast to tractor to maintain steering and braking control at all times. Do not exceed
tractor’s lift capacity or ballast capacity.
Before Operating

FIELD CULTIVATORS — Safety
1-6
• Comply with all laws governing highway safety when moving machinery.
• Use transport lights as required by all laws to adequately warn operators of other vehicles.
• Use good judgment when transporting equipment on highways. Regulate speed to road conditions
and maintain complete control.
• Maximum speed of implement should never exceed 20 mph. Do not exceed 10 mph during off-
highway travel.
• Slow down before making sharp turns to avoid tipping. Drive slowly over rough ground and side
slopes.
During Transport
Pressurized Oil
• Relieve the hydraulic system of all pressure before adjusting or servicing. See hydraulic power
unit manual for procedure to relieve pressure.
• High-pressure fluids can penetrate the skin and cause serious injury or death. Use cardboard or
wood to detect leaks in the hydraulic system. Seek medical treatment immediately if injured by
high-pressure fluids.
• Hydraulic system must be purged of air before operating to prevent serious injury or death.
• Do not bend or strike high-pressure lines. Do not install bent or damaged tubes or hoses.
• Repair all oil leaks. Leaks can cause fires, personal injury, and environmental damage.
• Route hoses and lines carefully to prevent premature failure due to kinking and rubbing against
other parts. Make sure that all clamps, guards and shields are installed correctly.
• Check hydraulic hoses and tubes carefully. Replace components as necessary if any of the
following conditions are found:
- End fittings damaged, displaced, or leaking.
- Outer covering chafed/cut or wire reinforcing exposed.
- Outer covering ballooning locally.
- Evidence of kinking or crushing of the flexible part of a hose.

Preparing for Emergencies
Wearing Protective Equipment
• Keep a first aid kit and properly rated fire extinguisher nearby.
• Keep emergency numbers for fire, rescue, and poison control personnel near the
phone.
• Wear clothing and personal protective equipment appropriate for the job.
• Wear steel-toed shoes when operating.
• Wear hearing protection when exposed to loud noises.
• Do not wear additional hearing impairing devices such as radio headphones, etc

This section contains all of the instructions required for the complete assembly of the entire
field cultivator.
For your safety, and the safety of others, use proper tools and equipment and always use
safe working procedures. Refer to these instructions before starting any work on your machine.
• The procedures for assembling this unit were intended for two or more people.
For ease of assembly, install all hardware loosely until assembly is complete and then tighten
according to “Torque Chart” unless otherwise specified.
• KNOW AND UNDERSTAND SAFETY RULES BEFORE OPERATING OR SERVICING THIS MACHINE.

When servicing mounting arm or “Rolling Harrow”, it may be necessary to disassemble the
unit from the main frame. Refer to the following instructions for proper installation.
NOTE: To disassemble “Rolling Harrow”, reverse the following steps.
Arm Assembly
Assembly of the “One-Bar/Rolling Harrow” to the machine is best accomplished with the unit
setting on the ground.
See “Overhead Layouts” for dimensions showing mounting arm locations and harrow sizes
and location on rear of the machine.
NOTE: For ease of assembly, install all hardware loosely until assembly is complete, then
tighten.
1. Install mounting arms onto the rear of the
main frame tube with one 1/2”-13UNC U-bolt
(91434) and two locknuts (9800) per arm
(Fig. 3-1).
NOTE: Refer to the PARTS section for individual
components of the “Rolling Harrow Basket” and
“One-Bar/Leveler”.
