Farm Safety
Contrary to the popular image of fresh air and peaceful surroundings, a farm is
not a hazard-free work setting. Every year, thousands of farm workers are injured
and hundreds more die in farming accidents. According to the National Safety
Council, agriculture is the most hazardous industry in the nation.
How You Can Improve Farm Safety
You can start by increasing your awareness of farming hazards and making a conscious effort to prepare for emergency
situations including fires, vehicle accidents, electrical shocks from equipment and wires, and chemical exposures. Be
especially alert to hazards that may affect children and the elderly. Minimize hazards by carefully selecting the products
you buy to ensure that you provide good tools and equipment. Always use seat belts when operating tractors, and
establish and maintain good housekeeping practices. Here are some other steps you can take to reduce illnesses and
injuries on the farm:
• Read and follow instructions in equipment operator’s manuals and on product labels.
• Inspect equipment routinely for problems that may cause accidents.
• Discuss safety hazards and emergency procedures with your workers.
• Install approved rollover protective structures, protective enclosures, or protective frames on tractors.
• Make sure that guards on farm equipment are replaced after maintenance.
• Review and follow instructions in material safety data sheets (MSDSs) and on labels that come with chemical products
and communicate information on these hazards to your workers.

Orthman Manufacturing, Inc. does not limit the potential effects or injuries nor prevention measures to those listed above. They are provided solely as a
guideline to making your farm life safer. Always consult your Owner/Operators Manual for specific tool and equipment safety requirements.

High Risk Factors on Farms
The following factors may increase risk of injury or illness for farm workers:
• Age – Injury rates are highest among children age 15 and under and adults over 65.
• Equipment and Machinery – Most farm accidents and fatalities involve machinery. Proper machine guarding and doing
equipment maintenance according to manufacturers’ recommendations can help prevent accidents.
• Protective Equipment – Using protective equipment, such as seat belts on tractors, and personal protective equipment
(such as safety gloves, coveralls, boots, hats, aprons, goggles, face shields) could significantly reduce farming injuries.
• Take precautions to prevent entrapment and suffocation caused by unstable surfaces of grain storage bins, silos, or
hoppers. Never “walk the grain.”
• Be aware that methane gas, carbon dioxide, ammonia, and hydrogen sulfide can form in unventilated grain silos and
manure pits and can suffocate or poison workers or explode.
• Take advantage of safety equipment, such as bypass starter covers, power take-off master shields, and slow-moving
vehicle emblems.
• Medical Care – Hospitals and emergency medical care are typically not readily accessible in rural areas near farms.

IMPLEMENT GUIDANCE SYSTEM
TRACKER IV
INTRODUCTION
The Orthman Tracker IV Implement Guidance system was developed to provide industry
leading precision implement guidance. The Tracker IV is a supplemental, rearward mounted,
implement able to be utilized with virtually any exisiting row crop implement on the market.
Combining the unprecedented precision of the Tracker IV with the well known Orthman
durability results in the most advanced implement guidance system in agriculture.
Tracker IV mounting arms mount directly to an existing toolbar and extend rearward to
provide clearance for existing row units. The bolt-on mounting arms are constructed of
5” x 7” x 3/8” wall tubing.
The Tracker IV frame consists of a 5” x 7” x 3/8” wall cross tube positioned similar to that of the
existing toolbar. A spindle, yoke, and steering blade are then assembled allowing the steering
blade to protrude into the ground surface. The Tracker IV is available in 2, 3, 4, and 6 (pictured
above) blade models. Implement size and quantity of steering blades are in direct proportion,
with consideration also given to the objective of the implement. Cross tube lengths vary
dependent upon the desired quantity of steering blades.
The positioning or angle of the steering discs allows the Tracker IV to effectively steer
implement. Drawn implements have the ability to travel laterally more so than integral
implements attached close coupled to the towing device. NOTE: Sway bars should be
removed from any tractor towing a 3 point hitched implement to allow the Tracker to
adequately correct implement position.

TRACKER IV
The probe box is mounted to the existing toolbar. The probe box is outfitted with devices
(feeling rods, probe balls) to determine the position of the implement in regards to the
desired position. This information is continuously sent from the probe box to the console
which is positioned in the tractor cab. The console remote probe button allows the operator
to raise and lower the probing device at any time.
The Tracker IV feedback sensor is simultaneously receiving information in regards to the
position of the steering blades. This information is also being continuously sent to the console.
The console is always receiving information from both the probe box (implement position)
and the feedback sensor (steering blade position). The console processes information and
then sends that information to the proportional valve.
The proportional valve controls the hydraulic cylinder to stroke to a certain position. The
hydraulic cylinder essentially provides the steering discs with the force needed to pivot while
submerged in soil, returning the implement to the desired postion. Once the probe box
senses that the implement is in the correct position, the steering blades will return to center
and the implement will proceed until future probe box information prompts pivoting of
steering blades.
Steering blades are connected by tie rods. A single hydraulic cylinder allows all blades to
simultaneously pivot to the same degree providing consistent implement tracking correction.

IMPLEMENT GUIDANCE SYSTEM
TRACKER IV
The Tracker IV consists of an endless and uninterrupted flow of information into the console
from the probe box (implement current position) and the feedback sensor (steering
blade position). The console continouosly is processing this information in order to send
information to the proprotional valve. The proportional valve then instructs the hydraulic
cylinder to extend or retract to cause the steering blades to pivot and steer the implement
back to the intended course.
The Tracker IV is designed to improve the field accuracy of the implement operator. The
Tracker IV is able to be utilized on an array of implements to increase operator ease on
multiple platforms.
This manual is sequentially designed and written and is considered to be an integral
component of the Tracker IV and is designed to educate the owner and operators regarding
safety, preparation and set-up, installation, field settings, component identification,
maintenance, and troubleshooting of the Tracker IV. The owner and all operators are
responsible for reading and understanding the entire content of this manual before
attempting to manipulate the Tracker IV in any way. If all suggestions and instructions in
the manual are followed, all adjustments, operations, and maintenance will be simplified and
easier for the personnel involved in the operation of the Tracker IV. This manual is designed
to keep the operator safe and knowledgeable as well as prolong the life of the implement,
minimize downtime, and maximize profits. This manual should accompany the implement
if it were ever to be sold.
We would like to thank you for placing your confidence in Orthman Mfg., Inc.
Your Tracker IV is manufactured to meet the highest standards and is built with precision
