Inspection and Testing before Every Tractor Delivery
From incoming components and assembly verification to hydraulic, PTO, electrical, steering, braking, road testing and final configuration checks, YUFENG follows a multi-stage tractor inspection process.
Quality Control throughout Tractor Production
Tractor quality cannot be confirmed through a final appearance check alone. Components, assembly, fluid systems, electrical systems, controls, optional configurations and complete-machine functions should be reviewed throughout production.
YUFENG's quality control process is designed to identify configuration differences, assembly issues, functional abnormalities, leakage risks, missing accessories and packing inconsistencies before delivery.
The exact inspection scope depends on tractor model, configuration, order agreement, destination market and customer requirements.
Quality control is a process of verification, testing, recording and corrective action—not only a final inspection.VIEW YUFENG FACTORY
Inspection from Components to Container Loading
Inspection items and sequence may vary according to tractor model and production process.
Check Components before Assembly
Incoming inspection scope depends on component type, supplier agreement and internal quality requirements.
VIEW TRACTOR PARTS
Verify Engine Information and Operating Condition
Engine inspection criteria depend on the selected engine, tractor model and technical requirements.
Check Power Transmission and Gear Operation
Transmission and drivetrain functions must be verified according to the actual tractor configuration.
Verify Structure, Alignment and Connections
Structural inspection should focus on correct assembly, visible damage, alignment and secure connection.
Verify Each Installation Stage
Correct assembly reduces the risk of functional failure, leakage, abnormal wear and delivery inconsistency.
Check Critical Bolts and Connections
Torque values and verification methods must follow the applicable technical documentation for each model.
Review Routing, Protection and Connections
Check Hydraulic Functions and Connections
Hydraulic test values depend on tractor model, hydraulic system and confirmed configuration.
Verify PTO Selection, Engagement and Operation
PTO speed and spline configuration must match the confirmed tractor and implement requirements.
WATCH PTO TEST VIDEOCheck Lifting, Lowering and Linkage Operation
Linkage category, lifting capacity and control functions depend on the tractor model.
Check Starting, Lighting and Instrument Functions
Review Steering Response and Connections
Steering inspection should be completed before and during the driving test.
Check Service, Parking and Trailer Brake Functions
Brake testing criteria depend on tractor model, brake system, test area and local requirements.
Observe the Tractor during Operation
Final diagnosis of an abnormal condition may require additional measurement or technical inspection.
Review Fluid Systems and Connections
Verify Controls, Visibility and Installed Options
ROPS, seat belt, labels and operator protection components should be checked according to the confirmed configuration and applicable requirements.
Confirm Tires, Dimensions and Final Appearance
Track width, tire configuration and overall dimensions must match the confirmed order.
Check Customer-Specific Branding and Configuration
OEM configuration should be reviewed against the approved files and confirmed order documents.

Verify What Should Be Delivered with the Tractor
Final accessories and documents depend on the confirmed order and packing list.
Check the Tractor before Protective Packing
Confirm Products, Parts and Documents before Shipment
Container quantity and loading arrangement depend on tractor dimensions, cabin, tires, disassembly and container type.
REQUEST LOADING INFORMATIONKeep Product and Inspection Information Traceable
Record format and retention period depend on YUFENG's verified internal process.
Identify, Correct and Reinspect
