John Deere has announced that its Final Tier 4 diesel engines are now officially approved to run on biodiesel blends up to B30, raising the limit from the previous B20 standard. The move expands fuel flexibility for operators while aligning with the company’s sustainability commitments and the growing role of renewable fuels in agriculture and heavy equipment.
Alongside biodiesel, these engines are already cleared to use renewable diesel (HVO) at up to 100% (RD100). Deere highlighted the change at this year’s Farm Progress Show, where all ride-and-drive equipment ran on the higher biodiesel blend.
Where Deere’s Final Tier 4 Engines Are Used
The new B30 approval applies across Deere’s wide equipment lineup:
- Agricultural tractors (row-crop, utility, and high-horsepower models).
- Combine harvesters and grain-handling machinery.
- Self-propelled sprayers and planting systems.
- Forage harvesters and balers.
- Forestry machines such as skidders and forwarders.
- Construction and roadbuilding equipment (loaders, dozers, excavators).
- Stationary and OEM power applications.

Broader Sustainability Strategy
John Deere has been clear about its long-term commitment to renewable fuels. In addition to biodiesel and renewable diesel, the company is exploring higher ethanol blends, including a concept 9.0-liter ethanol engine capable of running on E98, which produces up to 40% lower greenhouse gas emissions compared to conventional gasoline engines. Deere has also outlined targets for low- and no-carbon alternatives by 2030 and is incorporating recyclable materials into its product development.
