Deere & Co. is investing $70 million to expand manufacturing capacity in its Waterloo, IA, operations, where large farm tractors are built for use around the world. The investment will increase capacity by more than 10% by the middle of 2013, helping Deere to better meet the continuing strong demand it sees for large tractors worldwide. Once the improvements are completed, enhancements to Waterloo facilities since 2002 will have increased manufacturing capacity for large tractors by more than 50%. Tractors built in Waterloo are shipped to more than 130 countries each year. Deere does not expect the investment to add manufacturing jobs there.
