U.S. manufacturers appear to be racing the clock before the Trump administration tightens economic relations between the U.S. and Cuba. Over the last week, both John Deere and Caterpillar announced agreements with the Cuban government that might let the two Illinois-based companies sell farm tractors and other heavy equipment on the island. The occasion for this rush of activity was the annual Havana International Fair, Cuba’s largest commercial fair. Focus of the event is the Mariel Special Development Zone, a container ship facility near Havana and center of Cuba’s import/export businesses.In June, President Donald Trump announced that he was “cancelling the last administration’s completely one-sided deal with Cuba.” He did not give specifics, but administration officials said details would follow within 90 days. Those details have not been made public yet. With that in mind, Deere announced it would send 5000 Series tractors (between 75-115 horsepower) to Cuba this month. “This equipment is for testing and appraisal to ensure it will work with specific Cuban agricultural conditions and farming practices,” said Deere spokesman Ken Golden. A report in Manufacturer News quotes Golden as saying Deere would send “several hundred tractors and associated implements” over a four-year period.
