Existing-Machine Solutions

When you need to meet local emissions requirements and bid specifications, and your John Deere dealer can help you make choices based on your specific needs. Local emissions requirements can change over time, so our emissions specialists stay current with both the requirements and strategies to meet them.

Retrofit

Retrofitting your equipment with aftertreatment involves installing verified diesel particulate filters (DPFs) and/or oxide of nitrogen (NOx) control devices that will reduce particulate matter (PM) and NOx emissions. DPFs and NOx aftertreatment are the devices most commonly used to retrofit construction equipment.


Device Verification

When retrofitting equipment, owners need to ensure the device used has been verified to meet or exceed EPA or California Air Resource Board (CARB) emission reduction requirements. Verification provides regulatory approval and confirmation that the device meets emissions targets and can be installed by a third party outside of an OEM facility. Different regulatory verification levels are designated for each aftermarket device. Fleet managers should select aftermarket devices with the highest verification levels to achieve Best Available Retrofit Technology (BART).


Applicable Equipment

Some applications simply do not have the physical space to accommodate a DPF, which can be significantly larger and heavier than the muffler it often replaces. Retrofit typically isn't recommended on machines with Tier 1 and older engines because the higher oil consumption of these engines may reduce the reliability and overall operating cost of the device. When considering retrofitting solutions, work with your equipment dealer and consider the cost of the aftertreatment device installed in relation to the cost of other available emission-reduction options.


Requirements and Funding

Requirements across the country vary and there are also some funding programs that can help pay for the cost of retrofit. We have developed a database to help you find national, regional, state, and local retrofit programs and regulations.

Models with Compatible Retrofit Kits
John Deere has collaborated with retrofit supplier Nett Technologies, Inc., based in Toronto, Canada, to offer an actively regenerated DPF solution for key legacy John Deere construction machines. Nett has secured California Air Resource Board (CARB) level 3 verification for the VorTEQ™ 100 DPF, and it will carry the CARB 5-year/4,200-hour mandatory warranty. The VortTEQ system utilizes a controller, monitor, and diesel burner to monitor filter condition and control regeneration. It is a stand-alone system and does not interact with vehicle electronic or operator monitor systems, meeting local line-of-site requirements.

 

This is a unique offering for our customers, as Nett not only developed and verified the retrofit technology, but has also worked closely with John Deere Construction & Forestry engineering to design, validate, and package these under-the-hood kits.

 

The chart below shows the equipment models that have compatible retrofit kits. More verified kits will be added in the future. Kits are available through your John Deere dealer. Please contact your dealer for additional information.

Repower

The most important consideration when repowering off-highway equipment with a new or remanufactured engine is the residual value of the equipment. In general, higher horsepower machines are better candidates for repowering because of the higher cost of fully replacing them.


We find you are more willing to bear repower costs when the engine already has to be replaced because of catastrophic failure. If you intend to keep the machine for a long time, a repower makes the most economical sense.

Unavailability of an engine that matches your application may be a limitation to repowering. A smaller engine compartment space in older machines sometimes prevents installation of a higher tier engine, so not all machines have repower options.


John Deere Repower Kits

Kits are available to upgrade some John Deere engines to higher emissions tiers.

John Deere New and Remanufactured Engines

In some cases, you may be able to replace your engine with a new or remanufactured engine. Your dealer can help determine if this solution is available for your machine.

Rent

Consider renting or leasing higher-tier units from your John Deere dealer or any of our rental company partners. This is a cost-efficient solution and the quickest way to work in nonattainment areas or to meet bid specs.

Replace

Purchasing new equipment with the latest certified engine generally ensures that the equipment will meet local emissions requirements, and can be the best long-term financial decision for you.


When sourcing machines certified to the latest EPA emissions standard, it is important to note that all machines in a manufacturer's line may not meet this standard. For example, one manufacturer's 4-yard loader may be certified to Interim Tier 4 standards while another manufacturer's 7-yard model is certified to Tier 3 standards. The use of EPA transition allowances, or different emission standard effective dates based on an engine's power category, are two possible explanations. Understanding exactly what is required now and may be required in the future is critical to making the right choice.
