The new agreement extends a relationship with Fiserv that began in 2000.
Fiserv will continue to support John Deere Multi-Use Account loans, which assist with the growing season procurement needs of its clients.
Fiserv will also provide complete lifecycle management for the John Deere closed-loop credit card portfolio that enables accountholders to make purchases at franchise- or factory-owned John Deere store locations.
Fiserv Card Services president Vincent Brennan said: "John Deere is an iconic American company, and its revolving credit products are vitally important to their customers — who play a pivotal role in the economic well-being of our nation.
"We are excited to continue delivering these important payment services, which provide John Deere customers with speed and convenience they need to live and work today."
