Core Responsibilities

Primary Functions

Diagnose complex mechanical failures on tractors, combines, balers, sprayers, and tillage equipment using both hands-on inspection and computerized diagnostic tools; identify root causes and recommend cost-effective repairs and replacements.
Perform complete engine overhauls and mid-life services on diesel engines including compression testing, fuel system diagnosis, injector servicing, turbocharger inspection, and emission control troubleshooting to restore performance and meet manufacturer specifications.
Troubleshoot and repair hydraulic systems—pumps, valves, cylinders, hoses, and fittings—by performing pressure tests, identifying leaks, replacing seals, and calibrating flow/pressure settings to ensure safe, efficient operation.
Inspect, diagnose, and repair electrical systems and components including wiring harnesses, alternators, starters, sensors, control modules, CAN bus networks, lighting systems, and battery systems using volt/ohm meters and diagnostic software.
Service transmission and drivetrain components: clutch adjustments, gearbox repairs, final drive servicing, PTO shafts, U-joints, and differential work to maintain proper power transfer and reduce downtime.
Conduct preventative maintenance programs including scheduled oil and filter changes, lubrication, belt and chain adjustments, tire and track inspections, alignment checks, and seasonal preparation to maximize equipment life.
Fabricate and weld metal components, repair frames, mounts, hitches and custom brackets using MIG/TIG/stick welding processes and metalworking equipment to restore structural integrity to implements.
Install, calibrate and troubleshoot precision agriculture systems—GPS receivers, autosteer controllers, yield monitors, rate controllers, and ISOBUS devices—working with software updates and data transfer for optimized field performance.
Perform on-farm mobile service calls to diagnose and repair equipment under field conditions, ensuring rapid response to harvest- and planting-season emergencies while maintaining safe practices and clear communication with operators.
Read and interpret manufacturer service manuals, parts diagrams, schematics, and repair bulletins to perform accurate repairs and apply the latest technical updates and recalls.
Order, manage, and track parts inventory; source hard-to-find components, maintain parts bin organization, and recommend stocking levels to reduce turnaround time on repairs.
Maintain accurate service records, repair logs, and maintenance schedules in shop management systems, ensuring traceability of work performed and parts used for warranty and billing purposes.
Perform alignment and calibration of planter and seeding equipment, including row-unit adjustments, seed meter calibration, and closing system checks to ensure planting accuracy and yield optimization.
Diagnose and repair air conditioning, heating, and cab climate control systems to maintain operator comfort and system reliability during extended field operations.
Provide technical guidance and training to operators and junior technicians on correct equipment operation, daily checks, basic troubleshooting, and safety protocols to reduce misuse-related failures.
Implement safety checks and repairs for machine guarding, ROPS, seat belts, lights, mirrors, and emergency systems to ensure compliance with OSHA and manufacturer safety standards.
Carry out seasonal preparations including winterization and spring commissioning—draining systems, applying corrosion protection, storing attachments correctly, and re-commissioning equipment for the upcoming season.
Support warranty and claims processing by documenting defects, communicating with manufacturer representatives, and completing required paperwork to obtain proper credit or coverage.
Optimize equipment performance through preventive upgrades, retrofits, accessory installations, and aftermarket modifications such as weight distribution, tire/track choices, and implement integration.
Collaborate with parts, sales, and operations teams to plan shop workflow, prioritize emergency repairs versus scheduled maintenance, and communicate realistic timelines to customers and farm managers.
Test-drive and field-test repaired equipment under relevant load conditions to validate repair quality, tune performance parameters, and obtain operator sign-off on completed work.
Maintain a clean, organized, and safe shop environment by following 5S practices, performing regular tool calibration and inspection, and ensuring proper disposal of oils, coolants, and hazardous materials.

Secondary Functions

Assist in developing and continuously improving preventive maintenance checklists and equipment lifecycle plans for the farm or dealership fleet.
Provide on-site operator training sessions and briefings about new equipment features, recommended maintenance intervals, and safe operation best practices.
Support parts counter with technical knowledge for customers seeking replacement components or troubleshooting guidance.
Participate in after-hours on-call rotation to support critical harvest and planting-period repairs, ensuring minimal production disruption.
Help evaluate and trial new tools, diagnostic software, and technologies to improve service speed and diagnostic accuracy.
Contribute to estimating labor and parts for service quotes, helping managers prepare bids for large repair jobs or fleet service contracts.
Support green-field installations of irrigation pumps, grain handling systems, or other farm infrastructure when mechanical expertise is required.
Provide feedback to product development or purchasing teams about recurring failure modes, suggested design improvements, and common parts needs.
