Lesson 8. Field Performance and power requirements

Improving field efficiency: The ability to improve field efficiency is the next important step in developing machinery management skills. There are several important reasons why a machine may have certain field efficiency. Some lost-time factors are built into operation. Good planning and management can eliminate other lost-time factors. For example: Turning time and field operations: Turning time is one loss factor built into every field operations but can be kept to minimum by planning fields with longer rows. A normal turn at the end of a field is one that can be made with one continuous motion.

Unclogging machine: One time factor that can be nearly eliminated by good management is unclogging machines. It is also a main reason for an unusually high percentage of lost field time. There are three main reasons for clogging a machine.

1) Overloading the machine

2) Faulty working of the machine

3) Operating the machine when conditions are not right

By checking out machines ahead of the season there will be less clogging and field efficiency will improve substantially.

Making adjustments: With most machines, it is necessary to make adjustments before going to the field. Some machines, like combines or balers, have to be adjusted occasionally in the field as crop conditions vary throughout the day.

Reducing breakdowns: It is impossible to predict when some parts of a machine will fail, but many machine breakdowns in the field can be avoided by making thorough inspections before and during operation. To help eliminate or reduce breakdowns the following points need to be considered:

1) Inspect and repair the machines well ahead of the use season.

2) Carry out preventive maintenance.

3) Avoid rocks, holes and obstructions.

4) Drive cautiously in rough fields.

5) Avoid overloading the equipment.

6) Check out strange sounds, vibrations or smells.

7) Make small repairs when needed.

8) Use periodic checking to locate potential trouble.

9) Keep all power transmitting members adjusted, aligned and lubricated.

Rest stops: Short but frequent breaks or rest stops are desirable and necessary from both the standpoint of safety and improved performance. When the operator has to continually concentrate on a job, a short break every hour or so will increase alertness, reduce accidents and improve the quality of work.

Unmatched machine capacity: One major cause of an inefficient operation is a system of unmatched machines. It is always important to use the matching equipment with the power source.
