Load-Sensitive Hydraulic System for Allis-Chalmers Models 7030 and 7050 Agricultural Tractors 730860

A new and unique load-sensitive hydraulic system is now available on the new Allis-Chalmers Models 7030 and 7050 agricultural tractors. Although the system is considered very efficient and effective by experts, use of the system has been limited in the mobile equipment industry. This paper highlights the application of the load-sensitive circuit in the A-C 7030-7050 tractors. The circuit combines the advantages of the two basic types of systems used in tractors-fixed flow (open-center) and variable flow (constant-pressure, closed-center)-and avoids their major disadvantages.
