Combined Harvester Operator Course

Lesson 1 • Personal Protective Equipment and Site Rules

Covers mandatory PPE selection and general site conduct rules for harvesting operations. Establishes a safety-first mindset from day one.

Lesson 2 • History and Role of Combine Harvesters

Traces the evolution from manual harvesting to modern combines and establishes why efficiency matters. Sets context for all subsequent technical learning.

Lesson 3 • Operator Cab and Controls Familiarization

Introduces the cab layout, instrument panel, and primary controls. Ensures operators can locate every control before starting any practical exercise.

Lesson 1 • Rollover and Slope Operation Safety

Covers stability limits, rollover protective structures, and safe slope-driving techniques. Directly prepares operators for challenging terrain encountered in later chapters.

Lesson 2 • Fire Prevention and Suppression

Addresses the high fire risk from crop debris, heat, and fuel systems on combines. Operators learn prevention routines and first-response suppression techniques.

Lesson 3 • Electrical and Fuel System Safety

Explains risks from high-voltage systems, battery handling, and fuel leaks. Provides inspection and shutdown procedures to prevent electrical fires and fuel incidents.

Lesson 4 • Regulatory Framework for Agricultural Machinery

Explains operator duty-of-care obligations and machinery safety regulations without referencing specific codes. Connects compliance to daily operational decisions.

Lesson 1 • Machine Settings for Crop Conditions

Introduces initial threshing, concave clearance, and fan speed settings based on crop type. Provides a baseline configuration before fine-tuning is taught in later chapters.

Lesson 2 • Header Selection and Attachment

Explains how to select the correct header for the crop type and safely attach it to the feeder house. Prepares operators for the crop-specific setup covered in later chapters.

Lesson 3 • Walk-Around Inspection Procedure

Teaches a structured exterior inspection sequence covering tires, guards, belts, and fluid levels. Builds the habit of systematic checking before every start-up.

Lesson 1 • Operating on Slopes and Uneven Terrain

Applies slope safety principles from Chapter 2 to practical driving techniques on hills and rough ground. Operators maintain machine stability and grain quality on challenging terrain.

Lesson 2 • Road Transport and Public Highway Rules

Covers legal transport width, lighting requirements, and safe road travel practices for combines. Prepares operators for moving machines between fields and farms.

Lesson 3 • Field Entry and Headland Turns

Teaches controlled field entry, turning radius management, and headland maneuvering patterns. Reduces crop damage and soil compaction during turning operations.

Lesson 4 • Safe Start-Up and Shutdown Procedures

Details the correct engine start sequence, warm-up requirements, and controlled shutdown steps. Prevents mechanical damage and ensures operator safety at every session boundary.

Lesson 1 • Ground Speed and Throughput Management

Teaches how to match ground speed to crop yield and moisture for consistent machine loading. Prevents overloading, blockages, and excessive grain loss.

Lesson 2 • Grain Tank Monitoring and Unloading

Explains grain tank capacity management, unloading-on-the-go techniques, and coordination with grain carts. Keeps harvest flow continuous and reduces downtime.

Lesson 3 • Straw and Chaff Management

Covers chopper, spreader, and windrow settings for straw and chaff disposal. Affects soil health, subsequent field operations, and fire risk management.

Lesson 4 • Harvesting Patterns and Field Planning

Introduces round-the-field, back-and-forth, and split-field harvesting patterns. Operators select the most efficient pattern based on field shape and crop layout.

Lesson 1 • Separation System Tuning

Covers straw walker or rotary separation adjustment to recover grain carried over in straw. Reduces separation loss, which is a major source of overall grain loss.

Lesson 2 • Cleaning System Calibration

Teaches fan speed, sieve opening, and chaffer adjustment to produce clean grain samples. Balances cleaning efficiency against grain loss over the sieves.

Lesson 3 • Threshing System Principles and Adjustment

Explains how cylinder or rotor speed and concave clearance affect threshing efficiency and grain damage. Operators set and adjust these parameters for each crop.

Lesson 4 • Grain Loss Monitoring and Reduction

Introduces loss monitor sensors, manual pan testing, and systematic loss reduction strategies. Operators quantify and minimize total grain loss across all machine systems.

Lesson 1 • Lubrication Systems and Grease Points

Maps all grease nipples, automatic lubrication systems, and oil bath components on the machine. Ensures complete lubrication coverage to prevent bearing and shaft failures.

Lesson 2 • Daily Maintenance Tasks

Covers cleaning, lubrication, and inspection tasks required at the end of every operating shift. Prevents debris buildup, premature wear, and fire hazards.

Lesson 3 • Engine and Hydraulic System Servicing

Covers engine oil change, filter replacement, and hydraulic fluid and filter service intervals. Maintains engine performance and hydraulic system integrity across the season.

Lesson 4 • Seasonal Storage and Recommissioning

Details end-of-season storage preparation and spring recommissioning steps to protect the machine during off-season. Extends machine service life and reduces repair costs.

Lesson 1 • Drive and Transmission Fault Diagnosis

Identifies symptoms of belt slip, chain failure, gearbox noise, and hydrostatic drive faults. Operators distinguish operator-serviceable faults from those requiring specialist repair.

Lesson 2 • Field Repairs and Emergency Procedures

Covers essential field repair tools, temporary fixes, and emergency communication when breakdowns occur. Keeps operators productive and safe when specialist support is unavailable.

Lesson 3 • Blockage Detection and Clearance

Covers identification and safe clearance of blockages in the feeder house, threshing, and cleaning systems. Prevents secondary damage and operator injury during clearance.

Lesson 4 • Electronic and Sensor Fault Interpretation

Teaches reading fault codes, warning lights, and diagnostic displays on modern combine control systems. Enables operators to act on electronic alerts before failures escalate.
