Those who have older used tractors and other pieces of equipment may wonder how they can make them comply with new emissions regulations.
Recently, farm equipment producer John Deere said that retrofitting an approved engine may be one option for old Tier 0 and Tier 1 machines. However, doing so could come with significant costs, as the newer motors may require that the tractor be reconfigured.
If a new engine seems like too much of an expense, some may consider purchasing a refurbished model, although this too could come with the expense of fitting it into the used tractor.
Because of the amount of particulate matter emitted by these used tractors, attaching filters to them will not make them compliant.
The Environmental Protection Agency's Interim Tier 4 regulations take effect on January 1, 2011. As a result, fleet operators may have to change some of their procedures or running times in order to stay compliant.
Companies like John Deere have been developing new technologies in the face of the regulations, including filters and diesel engines that meet specifications.
