Synopsis

This course examines the functional requirements of the major groups of machinery and investigates the engineering principles and subsystems which underlie their operation. It develops the knowledge and skills necessary to analyse and predict machine performance, and to advise and assist farmers in the choice and efficient operation of a wide range of machinery. It also includes discussions of alternative energy resources and uses in agriculture as well as recent applications and industry developments in automation and precision agriculture. Tractor performance and testing are investigated. Tillage, planting, spraying and harvesting machinery are described and analysed. The thermodynamics of grain drying and controlled environments are also investigated. The course uses real world data sets from both field and lab work to show how the theory is related to practice.

Objectives

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. understand the importance of uses of energy and renewable energy in agriculture, and their impacts on environment;
  2. describe the operating principles of internal combustion diesel engine;
  3. describe the measurement and calculations of engine PTO, and tractor drawbar performance;
  4. compare the different types of tillage implements and select the most suitable type for various purposes;
  5. compare the different types of planters and different types of spraying equipment;
  6. appraise the function of grain and other crop harvesters;
  7. describe the differences of various fans, pumps and irrigation systems;

Important assessment information

  1. Attendance requirements:
    It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    Due to COVID-19 the requirements for S1 2020 are: To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course.

    Requirements after S1 2020:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the marks available for that assessment item.
    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.
    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure (point 4.4.2).

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.

  6. Examination information:
    Due to COVID-19 the requirements for S1 2020 are: An Open Examination is one in which candidates may have access to any printed or written material and a calculator during the examination

    Requirements after S1 2020:
    Candidates are only allowed to access specific materials during a Restricted Examination. The only materials that candidates may use in the restricted examination for this course are:
    i. writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination);

  2. Students must retain a copy of each item submitted for assessment. This must be despatched to USQ within 24 hours if required by the Examiner.

  3. In accordance with 精东传媒app Policy, the Examiner may grant an extension of the due date of an assignment in extenuating circumstances.

  4. If electronic submission of assessments is specified for the course, students will be notified of this in the course Introductory Book and on the USQ 精东传媒app Desk. All required electronic submission must be made through the Assignment Drop Box located on the USQ 精东传媒app Desk for the course, unless directed otherwise by the examiner of the course. The due date for an electronically submitted assessment is the date by which a student must electronically submit the assignment. The assignment files must be submitted by 11.55pm on the due date using USQ time (as displayed on the clock on the course home page; that is, Australian Eastern Standard Time).

  5. If the method of assessment submission is by written, typed or printed paper-based media students should (i) submit to the Faculty Office for students enrolled in the course in the on-campus mode, or (ii) mail to the USQ for students enrolled in the course in the external mode. The due date for the assessment is the date by which a student must (i) submit the assessment for students enrolled in the on-campus mode, or (ii) mail the assessment for students enrolled in the external mode.

  6. The Faculty will NOT normally accept submission of assessments by facsimile or email.

  7. Students who do not have regular access to postal services for the submission of paper-based assessments, or regular access to Internet services for electronic submission, or are otherwise disadvantaged by these regulations may be given special consideration. They should contact the examiner of the course to negotiate such special arrangements prior to the submission date.

  8. Students who have undertaken all of the required assessments in a course but who have failed to meet some of the specified objectives of a course within the normally prescribed time may be awarded one of the temporary grades: IM (Incomplete - Make up), IS (Incomplete - Supplementary Examination) or ISM (Incomplete -Supplementary Examination and Make up). A temporary grade will only be awarded when, in the opinion of the examiner, a student will be able to achieve the remaining objectives of the course after a period of non directed personal study.

  9. Students who, for medical, family/personal, or employment-related reasons, are unable to complete an assignment or to sit for an examination at the scheduled time may apply to defer an assessment in a course. Such a request must be accompanied by appropriate supporting documentation. One of the following temporary grades may be awarded IDS (Incomplete - Deferred Examination; IDM (Incomplete Deferred Make-up); IDB (Incomplete - Both Deferred Examination and Deferred Make-up).
