After extensive testing, John Deere confirms that their PowerTech IT4 engines at or above 175 hp (130 kW) can go up to 15,000 hours between Diesel Particulate Filters (DPF) ash removals. What does this mean for your fleet? Less downtime and more efficiency on the job site.

Many other equipment manufacturers have a set DPF ash cleaning interval that corresponds with the EPA minimum of 4,500 for machines at or above 175 hp (130kW). This means that depending on your use conditions and maintenance practices, you can expect up to two to three times the DPF life before a filter exchange for ash removal service is required on John Deere IT4 construction machines at or above 175 hp (130 kW).

You may also see complimentary IT4 warranty programs in the market that cover up to two DPF exchanges. Make sure you research the details. You may find that the two covered DPF exchanges aren’t even necessary on a comparable John Deere machine.

Stay tuned for a follow-up blog post with more information on when ash removal services will be required for your John Deere IT4 construction machines.
