Quick checks before you begin
- Obtain the current machine manual
- Clean before inspecting
- Record condition by row
- Separate approved work from unresolved findings
Prepare the service record before the machine
- Current operator and service information for the exact model
- Previous-season repair and parts records
- Row-unit inspection sheet with row, drum and bar positions
- Lockout, PPE and safe cleaning procedures
- Labeled containers for retained samples
- Camera, light, scale and approved measuring tools
Use a consistent row-unit sequence
| Stage | Inspection focus | Output |
|---|---|---|
| 1. Clean | Lint, trash, deposits and access | Safe visible inspection area |
| 2. Spindles | Hand, damage, wear, rotation and position pattern | Replace/inspect list |
| 3. Bars/drum | Uniformity, bushings, heat, movement and contact evidence | Qualified service findings |
| 4. Doffers | Lug edge, tears, flexibility and column pattern | Condition map |
| 5. Moistener | Tank, filters, nozzles, pads and wetting | Delivery check |
| 6. Closeout | Fasteners, guards, test and unresolved items | Signed service record |
Turn inspection findings into a parts plan
Group findings into immediate replacement, qualified inspection, planned stock and monitor-in-season. Keep left-hand and right-hand spindles separated and tie every requested part to its reference, sample and row-unit context.
Major repairs and precision adjustments should be assigned to skilled technicians using the current model procedures.
Release the machine with unresolved items visible
A checklist is useful only when open findings remain visible. Record the person, date, evidence and source used for each completed item, and prevent an unresolved safety or contact issue from disappearing into a general 'checked' status.
Photos support review. A qualified person still needs to decide whether model-specific service requirements have been met.

Questions buyers and technicians ask
When should preseason inspection begin?
Begin early enough to obtain manuals, skilled service and parts without forcing unverified substitutions immediately before harvest.
Should the row unit be cleaned first?
Yes, under the approved cleaning and safety procedure. Deposits can hide wear, damage and contact evidence.
How should open findings be handled?
Assign an owner and status, attach evidence and prevent the machine from being released when the finding affects safe operation.
