User:MaryGaulke/sandbox/Challenger Tractor requests

Hi, I'm a COI editor for AGCO, a client of my employer, Porter Novelli. Some edit requests for this article:


 * In the "History" section, move the "Current" subsection into the "Early 21st century" section and update as follows:
 * The current production of Challenger tractors has expanded for a time to include both tracked and wheeled type tractors ., which were Both types are available in either row-crop or flotation type configurations depending upon the preference of the customer. Since their purchase in 2002, the Challenger brand has used a Caterpillar diesel engine in the majority of their models. However, with the introduction of the D series of each tractor model, AGCO began implementing the use of AGCO Power branded engines that are Tier 4i/Stage 3B emission compliant by using e3, a Selective Catalytic Reduction system which injects urea in engine's exhaust gas stream to reduce nitrogen oxides and particulate matter emitted to the atmosphere.

 * Add to end of 21st century section:
 * , only tracked tractors in the 700 Series (MT738, MT740, and MT743 models) and 800 Series (MT851, MT856, MT862, and MT865 models) are in production. AGCO began phasing out the Challenger brand in 2020.  Additionally, the Rogator application machine is now produced and sold under AGCO's Fendt brand name.


 * I think it makes sense to remove the "Former Models" and "Current Models" sections, per WP:DIRECTORY. If we'd prefer to retain and update these lists, I can help with sourcing and updating them.

Thanks for your time and feedback!
