John Deere Interim Tier 4 Retrofit Kit
To help support the use of John Deere equipment around the world, the Construction & Forestry Division is bringing to market a retrofit kit that will enable John Deere Interim Tier 4 (IT4) machines to be sold in countries where ultra-low sulfur diesel (ULSD) fuel is not available.
ULSD is diesel fuel with 15 parts per million or lower sulfur content. The conversion kit will be available in 2015. New John Deere equipment for export to non-ULSD countries will continue to offer lower tiered engines that meet regional emissions standards and will reliably operate with the local available fuel. 800.765.9588, deere.com
