CNH will begin releasing software updates in the fourth quarter of 2026 in response to updated U.S. Environmental Protection Agency (EPA) guidance related to emissions-system fault inducement timing.
The revised software is designed to give customers more time to plan and complete repairs before certain engine derates are triggered. CNH said the updates are intended to help reduce avoidable downtime during critical operating periods.
Software availability will start with priority products in the fourth quarter of 2026 before expanding to additional applications throughout 2027.
CNH is developing revised engine software aligned with the updated EPA guidance. The initial rollout will prioritize high-horsepower agricultural equipment, with additional product families to be added throughout 2027.
"Customers have been clear: they need solutions that help them stay productive, especially during seasonally critical windows," said Scott Harris, president, North America, CNH. "These updates are designed to give operators more practical flexibility in addressing emissions-system issues while supporting the performance and reliability they depend on across farms and jobsites."
The updates are intended to give equipment owners and operators additional flexibility when addressing emissions-system faults and planning repairs.
Customers with a CNH Electronic Service Tool subscription will be able to perform the software update themselves once it is available. CNH dealers will also be able to support installation remotely or on-site.
