On Site Harvester Repair in the Lockyer Valley: 24/7 Field Service
On site harvester repair in the Lockyer Valley means bringing the workshop to the paddock, so harvest doesn't stop. Yarrow Field Maintenance provides 24/7 field service across the Lockyer Valley and Darling Downs, covering diesel, auto electrical, ECM remapping and ARC-accredited air conditioning.

On-site harvester repair means diagnosing and fixing machinery where it sits, not towing it to a workshop. Harvest windows are short, and every hour off the paddock costs grain.
| Stage | What Happens | Typical Timing |
|---|---|---|
| Phone triage | We capture the fault, machine model and paddock location | On the call |
| Dispatch | A mobile unit is assigned and travels to the site | Depends on distance |
| On-site diagnosis | Fault codes, wiring checks, fuel and electrical testing | First hour on site |
Harvester Preventative Maintenance Checklist
A harvester preventative maintenance checklist is a scheduled set of daily, weekly and seasonal checks that catch wear before it becomes a breakdown, most harvest-season failures trace back to something visible earlier, like a loose terminal, worn belt or overdue filter.
Daily checks: engine oil and coolant levels; fuel filters and water trap drained; battery terminals clean and tight; belts and chains for tension and fraying; tyres and tracks for pressure and damage.
Weekly checks: grease all points; inspect rotor and concave for wear; check hydraulic hoses for weeping or cracks; blow out radiators and coolers.
Pre-season checks: full service to the manufacturer's interval; auto electrical inspection of the loom and connectors; air conditioning service before summer heat.
Harvester Electrical Fault Diagnosis
Harvester electrical fault diagnosis traces a fault through the machine's wiring, sensors, relays and control modules to find the true cause.
Common causes we find: corroded or loose earth connections; chafed loom at frame edges; failed relays and blown fuses from vibration; moisture in connectors after washing or rain.
