Learning outcomes

On successful completion of this module students should be able to:
Outcome 1
Select an appropriate agricultural tractor and machinery for a specified range of applications.

Performance criteria
Tractor sub-systems are identified (engine, transmission, hydraulics, hitches, cabs, controls)
Strengths and weaknesses of sub-system features are described (engine, transmission, hydraulics, hitches, cabs, controls)
Sub-system features are related to specific tractor / implement operations (engine, transmission, hydraulics, hitches, cabs, controls)
Prescribed methods are used to calculate operating costs (fixed and variable costs, usage, working life)

Outcome 2
Demonstrate the skills required to manage safe and efficient tractor/implement operations.
Performance criteria
Methods of improving tractive performance are identified (soil properties, tyre type and working condition)
Causes and means of reducing tractor instability and control loss are identified (surface, slope, tractor and implement characteristics, preparation, field procedures)
Implements are selected and set appropriately (calibration, accuracy of distribution)
Mechanical theories are related to field performance (forces, weight transfer)
Basic tractor/implement operations, maintenance and repaire are performed (procedures, routine maintenance, tractor, trailed/mounted operations).

Brief description

This module will provide an understanding of the engineering and selection criteria associated with the agricultural power unit and machinery and the knowledge required to operate, maintain and manage tractor / implement operations safely and efficiently. The module will be delivered by means of a combination of lectures, lecture demonstrations and practicals.
