EPA Interim Tier 4 and EU Stage III B emissions standards for diesel engines between 56 kW (75 hp) and 130 kW (174 hp) became effective the first week of 2012, raising questions among contractors about the design, operability and cost impact of compact equipment falling within this power range. John Deere’s team of engineers has addressed these concerns while providing the smooth operability and efficiency customers come to expect from their compact equipment.
We recently sat down with Sam Norwood, Manager of CWP sales and marketing for John Deere Construction & Forestry, to discuss what changes owners and operators will see in the new equipment, rolling out in 2013, and how it might affect their worksite.
Packaging – Yes the equipment will look slightly different to accommodate for engine layout changes, but visibility and ease of operation have not been compromised. From inside the machine you will still have excellent 360-degree visibility needed for operating these compact machines in tight areas.
Maintenance – Particulate matter accumulates in the Diesel Particulate Filter (DPF) and needs to be periodically cleaned. Like John Deere’s larger engines, an automatic cleaning process handles this requirement with no impact on machine productivity in most operating conditions. Periodic ash removal service for the DPF is condition based on John Deere machines, meaning the machine will tell you when the service is required. Depending on your operating conditions and fluids used, this interval may exceed the minimum 3,000-hour interval required by the EPA.
Operating Cost – Fitting all the new technology developed for IT4 compliance in a smaller machine results in some cost increase. Fuel consumption also increases during the periodic automatic filter cleaning process. However, using our proven cooled EGR technology as a foundation for our IT4 solution moderates the impact on overall fuel efficiency.
Education – If you’re new to the emissions conversation, start learning by getting familiar with new regulations and the new technologies being used to meet them.
