Quick Revision Summary (Key Takeaway)
The IMI Level 2 Diploma in Land-Based Technology (VRQ) covers the maintenance, repair, and operation of agricultural machinery and vehicles. It includes health and safety, engine systems, electrical systems, hydraulics, and workshop practices, preparing students for careers in agricultural engineering.
Topic Overview
The IMI Level 2 Diploma in Land-Based Technology (VRQ) is a vocational qualification designed for students who want to work in the agricultural engineering sector. It covers a broad range of skills and knowledge required to maintain and repair agricultural machinery, including tractors, combines, and other farm equipment. The qualification is recognised by employers and provides a solid foundation for further study or an apprenticeship.
The course is structured around practical workshop skills and theoretical understanding. Key areas include health and safety legislation, engine systems (both petrol and diesel), electrical systems, hydraulic systems, and chassis and transmission components. Students learn to diagnose faults, carry out routine maintenance, and perform repairs to a professional standard. The qualification also emphasises the importance of environmental sustainability and efficient use of resources.
This diploma is part of the wider land-based technology sector, which is vital to modern agriculture. As farming becomes increasingly mechanised, the demand for skilled technicians grows. By completing this qualification, students gain the technical competence and confidence to enter the industry, whether as a service technician, machinery operator, or workshop supervisor. It also provides a stepping stone to advanced qualifications, such as the IMI Level 3 Diploma in Agricultural Engineering.

Learning Objectives
What you need to know and understand
- Be able to perform material preparation, shaping and assembly operations, Know how to carry out material preparation, shaping and assembly operations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Selects appropriate tools and equipment for the task.
- Measures and marks materials accurately.
- Performs shaping operations (cutting, drilling) safely.
- Assembles components securely using correct methods.
- Follows health and safety procedures throughout.
Assessment Guidance
Guidance for achieving higher grades
- 💡Double-check measurements before cutting.
- 💡Wear appropriate PPE at all times.
- 💡Keep work area tidy to avoid accidents.
- 💡Always use correct technical terminology, such as 'actuator' instead of 'ram' and 'relief valve' instead of 'safety valve'.
- 💡When answering questions about procedures, include specific safety checks and tools, as marks are often awarded for these details.
- 💡Practise reading wiring diagrams and hydraulic schematics – they appear frequently in exams and are a common source of lost marks.
Common Mistakes
Common errors to avoid in your coursework
- Incorrect measurement leading to wasted material.
- Using tools without proper safety checks.
- Poor alignment during assembly causing weak joints.
- Misconception: Hydraulic oil is just for lubrication. Correction: Hydraulic oil transmits power and also lubricates and cools components.
- Misconception: A diesel engine doesn't need spark plugs, so it has no ignition system. Correction: Diesel engines use compression ignition, but they still have a glow plug system for cold starting.
- Misconception: The battery is the main source of electrical power when the engine is running. Correction: The alternator supplies power and charges the battery when the engine is running.

Command Word Expectations (THE INSTITUTE OF THE MOTOR INDUSTRY)
What examiners look for when using specific command words in this specification
Give a detailed account of a process or component, including key features and functions. For example, 'Describe the function of a hydraulic relief valve' – you must state what it does and how it works.
Give reasons or causes, showing understanding of how and why something happens. For example, 'Explain why a diesel engine uses high compression' – you must link compression to ignition temperature.
Perform a mathematical calculation, showing all steps and units. For example, 'Calculate the hydraulic power' – you must use the correct formula and convert units.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A tractor's hydraulic system has a pump that delivers 40 litres per minute at a pressure of 180 bar. Calculate the hydraulic power in kilowatts (kW). Show your working.
- 1.Step 1: Convert flow rate to m³/s: 40 L/min = 40/1000 m³/min = 0.04 m³/min. Divide by 60 to get m³/s: 0.04/60 = 0.0006667 m³/s.
- 2.Step 2: Convert pressure to pascals: 180 bar = 180 × 100,000 = 18,000,000 Pa.
- 3.Step 3: Use the formula: Power (W) = Pressure (Pa) × Flow rate (m³/s). So, Power = 18,000,000 × 0.0006667 = 12,000 W.
- 4.Step 4: Convert to kW: 12,000 W / 1000 = 12 kW.
Question: Describe the procedure for safely changing a tractor wheel, including the tools required and safety precautions. (6 marks)
- 1.Step 1: Park the tractor on level ground, engage the parking brake, and switch off the engine. Remove the ignition key.
- 2.Step 2: Chock the opposite wheels to prevent movement. Use a suitable jack rated for the tractor's weight and place it under the recommended jacking point.
- 3.Step 3: Loosen the wheel nuts slightly before jacking up the wheel. Then jack the tractor until the wheel is clear of the ground.
- 4.Step 4: Remove the wheel nuts and pull the wheel straight off the hub. Use a wheel trolley or get assistance if the wheel is heavy.
- 5.Step 5: Fit the new wheel, aligning the holes with the studs. Hand-tighten the nuts, then lower the tractor and tighten the nuts in a diagonal pattern to the correct torque.
- 6.Step 6: Check the tyre pressure and ensure all tools are removed from the area.
