Total hours describe only one part of exposure. Add a position-based wear map, route and task context, and whatever reliable edge-engagement information is available. Normal reported hours do not establish that contact was evenly distributed across the blade or comparable with another truck's work.
Separate total hours from contact location and task exposure
Identify what the hours field actually measures: engine time, a plowing status signal, a hydraulic state or another recorded category. Obtain the system's definition rather than assuming that the label means continuous edge contact. Record gaps, resets or manual entries where known. Keep uncertainty in the data visible instead of treating a digital report as automatically exact.
Match the report to the period that this particular edge was installed. A machine's monthly hours can include an earlier blade, a later replacement or periods without the same attachment. Include installation and removal dates and note whether the clocks and records align well enough for the proposed comparison.
The telematics guide covers the broader role of vehicle data. The immediate question here is whether the hours field can explain uneven wear at particular positions. It cannot answer that spatial question without additional evidence.
Add wear maps, route segments and actual edge engagement information
Map remaining dimensions at identified positions using a consistent reference. Include photographs of the more-worn and less-worn areas and note any change from prior inspections. A single average remaining height would conceal the pattern the investigation is trying to understand. Preserve actual measurements separately from visual estimates.
Describe route sections, surface transitions, repeated turns, curb-side work and other task distinctions where records support them. Do not infer which end carried contact simply from the route map. Add operator observations and qualified assembly findings, identifying their dates and limitations. WESTERN's cutting-edge guidance provides background on wear factors; it does not turn aggregate hours into a load-distribution measurement.
Keep maintenance and part changes in the same timeline. If an edge was repositioned or a component replaced, the position map needs to show how references changed. Otherwise a later reading may be assigned to the wrong physical part of the blade.
Use telematics as context rather than proof the edge was uniformly loaded
Build a record that links the machine's activity to the physical inspection without overstating either. Where edge-engagement data exist, explain what they mean and how they were matched to the blade. Where they do not, say that actual contact exposure is not fully known. Avoid filling the gap with an assumed percentage of the reported hours.
Clear Roads' evaluation work supports the value of comparable field evidence, but no general protocol removes missing data from a retrospective case. A useful next step may be a better inspection map and clearer installation log, rather than more complex software or a new wear-rate formula. Ask which missing observation would actually change the maintenance or purchasing decision.
When discussing replacement edge options, send the wear map with the hours summary. Do not describe the material as failing under uniform loading unless that loading was established. The supported conclusion may be that normal aggregate activity coincided with a localized pattern that still requires assembly and task review.
