Managing agricultural machinery repairs often requires field technicians to diagnose complex mechanical failures under significant time pressure, especially during peak harvest seasons. To address this, developers can build an AI-powered repair assistant using Amazon Bedrock AgentCore, which leverages manufacturer documentation to provide guided troubleshooting and part identification through a natural language interface. The system utilizes Amazon Nova 2 Lite as its foundation model, paired with Amazon Bedrock Knowledge Base to implement retrieval-augmented generation (RAG, a technique for grounding AI responses in external data sources). Conversations are managed via AgentCore Memory, enabling the agent to retain context across diagnostic sessions and maintain long-term records of fleet-specific issues.

The technical architecture consists of four primary segments. The authentication and frontend layer uses Amazon Cognito and AWS Amplify to secure and host a React-based web dashboard. The AgentCore Runtime layer facilitates agent execution, providing a centralized /invocations endpoint that routes chat and CRUD requests. AI processing is handled by the Strands Agents SDK, which utilizes a custom search tool to query indexed equipment manuals stored in Amazon S3 via vector search through Amazon OpenSearch Serverless and Amazon Titan Embeddings. Finally, Amazon DynamoDB manages the persistence of service tickets, while CloudWatch and X-Ray ensure system observability.

Deployment involves populating a Knowledge Base with manuals—such as those for the John Deere 1023E and 1025R tractors—and executing the agent via the local AgentCore toolkit. Once configured, the agent synthesizes diagnostic advice based on manufacturer documentation with clear source attribution, allowing technicians to verify procedures directly against official guidelines. For testing purposes, Amazon Nova 2 Lite incurs costs of $0.30 per million input tokens and $2.50 per million output tokens, while OpenSearch Serverless charges approximately $0.24 per hour while active. Developers can extend the assistant’s capabilities by adding new tool functions to the codebase to support features like parts ordering or inventory lookups, without requiring underlying infrastructure modifications.
