What is a combine harvester pre-start checklist?
A combine harvester pre-start checklist is a structured inspection form used by the operator, owner or farm mechanic to verify the harvester is safe and operationally ready before each shift in the harvest window. Combines are among the largest, most complex and most accident-prone pieces of plant in Australian and US grain production. They combine a wide cutting and gathering header (often 12 to 18 metres on Class 9 plus machines), a high-speed threshing drum and concave, multi-deck sieves, a grain tank and unloading auger, a chopper and chaff spreader and a self-propelled drive train. The pre-start checklist covers each of these systems plus the engine, hydraulics, brakes, ROPS, fire suppression, lights and operator station, drawing from SAE J1163 (Standard Operations Manual for Self-Propelled Agricultural Equipment), ASABE engineering practice, AS/NZS 1418.18 where structural elevation features apply (separator drum housing access, header service platforms), AS 1636 for ROPS and AS 4024 plant safety principles.
Unlike a tractor pre-start (which focuses on PTO guard, drawbar, three-point linkage and ROPS), a combine pre-start covers many unique systems that drive harvest losses, fires and operator injury when ignored. The header reel, cutter bar, feeder house chain, threshing drum and concave clearance, sieve adjustment, grain tank auger, chopper knife condition and discharge fan are all combine-specific items that no other agricultural plant has. Combine fires are also a category of risk on their own: dry stubble, chaff dust and friction-heated bearings or belts have caused tens of millions of dollars of header and bushland fires across grain belts every year. The pre-start checklist forces the operator to inspect bearings, belts, dust accumulation, fire extinguisher charge and the cleanout schedule before the harvester starts the field. Documented daily inspections satisfy WHS Act 2011 plant duty obligations, support insurance claims after a header fire or rollover incident, defend OEM warranty on driveline components and reduce harvest downtime by catching the worn knife sections, belt glaze, blocked sieves and loose auger bolts that otherwise emerge mid-field at the most expensive moment in the season.

Benefits of using this combine harvester pre-start checklist
- Combine-specific coverage: a checklist tailored to header reel cutter bar threshing drum sieves grain tank chopper and drive train catches the failure modes generic plant pre-starts and tractor checklists routinely miss across the harvest window.
- Fire prevention: inspecting belts bearings dust accumulation fire extinguisher charge and the cleanout schedule before the field reduces the header fire risk that destroys tens of millions of dollars of crop and machinery across Australian and US grain belts every year.
- WHS compliance: a documented daily pre-start satisfies WHS Act 2011 plant duty obligations under Section 19 and WHS Regulations 2011 Chapter 5 for the largest piece of mobile plant in any Australian grain operation.
- Harvest loss reduction: catching worn knife sections cracked feeder chain links blocked sieves and out-of-spec concave clearance before each shift directly reduces header loss return loss and tank-sample contamination that cost operators 2 to 8 percent of yield when undetected.
- OEM warranty defence: a documented inspection log against SAE J1163 and the manufacturer service book is the evidence dealers and OEMs require on every driveline cleaning bearing and threshing system warranty claim during the in-warranty period.
- Operator handover quality: in shift work or owner-operator-contractor environments the signed pre-start is the formal handover document that proves the combine was inspected and accepted as safe before each operator took the wheel for the next field.

What to include in a combine harvester pre-start checklist
This combine harvester pre-start checklist covers 11 key areas:
- Combine identification: make and model, serial number, fleet ID, engine hours, separator hours, header attached (type and width) and operator name with licence or competency reference.
- Header and feeder house: cutter bar knife section condition, reel bat and tine condition, feeder house chain tension and links, auger flighting condition, header drive belts and stone trap clean.
- Threshing drum and concave: drum bar condition, concave clearance setting against crop, rasp bar and threshing element wear, drive belt condition and unobstructed access.
- Sieves and shaker shoe: upper and lower sieve clearance and openings, sieve drive linkages, shaker shoe motion check, return auger and grain pan condition.
- Grain tank and unloading: tank cleanliness and sample door, grain tank auger condition, unloading auger pivot greased, swing function operates and discharge spout clear.
- Chopper and chaff spreader: chopper knife condition and counterknife setting, drive belt and bearing, spreader vanes and discharge clear.
- Engine compartment: oil level, coolant level, fuel level and water separator, air filter pre-cleaner and restriction indicator, belts and exhaust integrity plus battery condition.
- Hydraulics, brakes and ROPS: hydraulic oil level and visible hoses, header lift and tilt cylinders, brake operation, ROPS frame integrity, seatbelt webbing and retractor lock.
- Tyres wheels and lights: tyre condition and pressure for front drive and rear steer, wheel nut torque check, all field and road lights, indicators, beacon and reverse alarm.
- Fire safety and cleanout: fire extinguisher charge date and accessibility, dust and chaff accumulation in engine bay and around bearings, blower function and the daily cleanout schedule completed.
- Defect register and sign-off: defect item description severity action required and responsible person plus operator and supervisor signatures with date and time.
How to use this combine harvester pre-start checklist
- Park the combine safe and capture identification: park on firm level ground with the header rested on the ground or service stand, engage the park brake, isolate hydraulics, shut down the engine and record make model serial fleet ID engine and separator hours header type and width and the operator name with competency reference before any further inspection.
- Walk the header and feeder house: inspect every knife section across the cutter bar for cracked or missing teeth, check reel bats and tines for damage and even spacing, inspect the feeder house chain for tension and missing links, check the stone trap is empty and the auger flighting has no bent edges before the day starts.
- Open the side panels and inspect threshing drum sieves and grain tank: rotate the threshing drum by hand to check rasp bar and concave clearance against the crop being harvested, inspect sieve openings and shaker shoe motion, check the return auger and grain pan for hold-up, walk into the grain tank to verify the unloading auger condition swing function and discharge spout clear of obstructions.
- Inspect engine bay hydraulics brakes ROPS chopper and fire safety items: open the engine bay and check oil coolant fuel air filter pre-cleaner battery and belts looking for dust accumulation against hot surfaces, walk under the combine to check hydraulic hoses for chafing and leaks, test the brakes and ROPS frame and seatbelt, inspect the chopper knife and counterknife and confirm the fire extinguisher is charged in date and accessible from the cab.
- Start engage and document defects: start the engine and verify gauges and warning lights are normal, engage the header drive at low speed and confirm the threshing drum sieves and chopper engage cleanly, raise and lower the header check brake function and steering response, document every defect against severity and responsible person and ensure the supervisor countersigns any safety-critical defect before operation.

A pre-start inspection must be completed before each shift during the harvest window. Combines work shifts that often exceed 12 hours during peak harvest, so any change of operator (shift handover, owner to contractor, contractor to relief) triggers a new pre-start inspection by the incoming operator. Daily cleanout (engine bay, threshing drum housing, sieves and chopper) at the end of each shift is treated as part of the pre-start cycle because dust and chaff accumulation is the leading cause of header fires. Weekly inspections add a deeper review of bearings belts hydraulic hose routing tyre pressure ROPS bolt torque and fire extinguisher charge date. Hour-meter milestones (typically 100, 250 and 500 separator hours) escalate the pre-start into a workshop service under the OEM service schedule. After any field event (rock strike, header damage, header fire near miss, operator incident) a fresh inspection is mandatory before the combine returns to work. MapTrack hour-meter triggers can schedule the daily pre-start, weekly inspection and 100 250 500 hour service due alerts against every combine asset.
