Overview

What this engagement was.

A leading Indian tractor OEM wanted to modernise its nationwide service network across both legacy mechanical tractors and modern ECU-equipped models.

The existing service approach was largely calendar-based, which meant maintenance decisions were not always aligned with real operating conditions, component health, field usage, or early failure signals.

DigiWagon built an AI-powered predictive maintenance platform that captures tractor telemetry during service visits, forecasts component health, predicts Remaining Useful Life, and dynamically recommends maintenance actions.

To extend the intelligence layer across the complete fleet, the solution also included a mechanical-to-digital retrofit kit that brought legacy, ECU-less tractors onto the same monitoring platform as newer connected models.

Why it mattered

Why Tractor Servicing Needed Predictive Intelligence

The OEM’s service network relied on fixed maintenance schedules and reactive diagnosis. This created a gap between how tractors were actually used in the field and how they were serviced at workshops.

Legacy tractors had no onboard electronics, while newer ECU-equipped models generated useful telemetry that was not being fully used after service sessions.

The OEM needed a system that could read operating signals, identify abnormal behaviour, forecast component degradation, and guide service engineers before a failure happened in the field.

Business Challenge

  • The service network depended on fixed, calendar-based maintenance schedules.
  • A large portion of the active fleet included legacy tractors with no onboard electronics.
  • Modern ECU-equipped tractors generated service data that was not being used for long-term intelligence.
  • Standard service intervals ignored actual operating conditions and component health.
  • Critical component issues were often detected only after breakdowns occurred.
  • Service teams had limited visibility into load patterns, regional usage, field conditions, and component-level wear.
  • Product engineering teams lacked real-world operating data from active tractors.
  • The platform needed to support both 3-sensor legacy tractors and 10-sensor modern tractors.

Manufacturing Context

In agricultural machinery, breakdowns during peak seasons can create high service pressure, customer dissatisfaction, and operational losses.

Predictive maintenance helps OEMs move from routine servicing to condition-based servicing, where every tractor is assessed based on real usage, sensor behaviour, component wear, and service history.

For mixed fleets, the challenge is not only building AI models. It is also creating a common data layer across older mechanical tractors and newer ECU-equipped machines.

User Problem

  1. Service engineers needed early warning signals before component failure.
  2. Workshop teams needed a single interface for both legacy and modern tractors.
  3. Field service teams needed data-backed maintenance recommendations.
  4. OEM teams needed visibility into real tractor usage across regions.
  5. Product teams needed operating insights to improve future engineering decisions.
  6. Legacy tractors needed to become digitally readable without replacing the whole machine.

What we built

The platform we shipped.

DigiWagon built an AI-powered predictive maintenance ecosystem that connects tractor telemetry, sensor retrofitting, service-station workflows, AI models, edge deployment, and service recommendations into one unified platform.

The system helps service engineers identify issues earlier, forecast component life, adjust service intervals, and support both legacy and modern tractors through a single service-bay interface.

Key features

Eight capabilities, one per constraint.

Cross-Generation Unified Dashboard

  • Built one service-bay dashboard for both legacy and modern tractors.
  • Supported 3-sensor retrofit data and 10-sensor ECU data.
  • Gave service engineers a consistent interface across the fleet.
  • Improved usability across workshops and service stations.
The service-bay dashboard — tractor selection across legacy and modern models beside the live view with oil pressure, oil temperature and cooling health.

Anomaly Detection

  • Built an alerting engine to detect abnormal sensor readings.
  • Flagged overheating, low oil pressure, RPM spikes, and unusual operating patterns.
  • Helped service engineers identify hidden issues during service visits.
  • Reduced dependency on manual diagnosis alone.
The anomaly log — engine RPM spikes, overheating and low oil pressure events flagged by severity across service visits.

RUL Prediction for Critical Components

  • Developed degradation models to forecast remaining hours till failure.
  • Covered engine oil, coolant, fuel filter, air cleaner, and injector subsystems.
  • Helped teams plan service action before component failure.
  • Supported condition-based maintenance recommendations.
