A calendar age is not enough to replace or retain a remote mower. Fleet decisions should combine hours and workload, condition, repair history, downtime, parts/support risk, safety updates, task fit, resale or redeployment value and the cost of disruption.
Direct recommendation
Set review triggers rather than a universal replacement year. Compare keep, overhaul, redeploy and replace scenarios using the same future workload and cost horizon. Replace when evidence shows that the selected action best controls whole-life cost, availability and operational risk.
Decision framework
| Area | Record |
|---|---|
| Use | Hours, shifts, seasonal peaks, site severity and utilisation |
| Condition | Inspection results, structure, tracks, cutter, controls and power system |
| Cost | Maintenance, repairs, downtime, transport and support burden |
| Fit | Current sites, access, vegetation, safety controls and operator needs |
| Decision | Keep, overhaul, redeploy, replace or retire with review date |
Create one asset record
Link serial/configuration, acquisition, hours, sites, maintenance, repairs, downtime and modifications. Missing history weakens every replacement calculation.
Separate age from economic life
A lightly used supported machine may remain useful; a newer machine can be uneconomic if it is mismatched or repeatedly unavailable.
Measure downtime consistently
Record failure start, diagnosis, parts wait, repair and return-to-service. Separate planned maintenance from avoidable outage.
Forecast future workload
Replacement should fit upcoming site segments, transport and service capacity rather than simply copying the outgoing specification.
Compare complete scenarios
Include capital, maintenance, parts, energy/fuel, training, transport, downtime and disposal or residual value with stated assumptions.
Set evidence-based triggers
Use condition, cost, availability, supportability and task-fit thresholds. Review after major failures, fleet changes or new operating requirements.
Minimum evidence pack
- Exact asset/product identity and current configuration.
- Dated site, service or transaction records from responsible people.
- Supporting documents, photographs and measurable observations.
- Named decision owner, unresolved risks and next review date.
