π Case Study
Mixed-Brand Fleet VT Integration at Midwest Precision Co-op
Inconsistent VT behavior during section control handoff between brands causing yield loss and operator frustration
ποΈ Project Overview
Consolidation of 42 tractors (John Deere, Case IH, CLAAS) and 68 implements across 3 states
π― Challenge
Inconsistent VT behavior during section control handoff between brands causing yield loss and operator frustration
π§ Design Approach
Standardized VT object pool definition, firmware harmonization via AEF-approved OTA updates, and unified display template deployment

π Key Calculations
Object Pool Synchronization Latency
Max(Tx Delay + Rx Delay + Processing Time)
Result: 217 ms
Must be < 250 ms per ISO 11783-10
π Results
98.2% section control reliability, 40% reduction in VT-related support tickets, full AEF certification achievedπ‘ Lessons Learned
