Expanding the Deere Family of Low-Speed High-Torque Hydraulic Motors 831273
The John Deere cam lobe motor introduced two years ago has found primary usage as auxiliary drive systems on harvesting machines. The performance and reliability have been well received on John Deere combines and forage harvesters and in some OEM applications. The basic family is now being expanded to provide new features and flexibility for the OEM market. The expansion to include fixed as well as steerable mountings, shiftable operation (1, 2 or 3 speeds), greater axle capacity and an optional brake will be described. The challenge of extending motor capability and flexibility while minimizing total number of family components and maintaining reliability will be addressed.
