Usage:
This hydraulic control arrangement will permit the use of an A.E.M. (Auxiliary Equipment Manufacturer) ripper or any rear mounted implement that needs a separate hydraulic circuit for its operation on the above machines. Modifications must be made to the machine before the control arrangement can be installed. This hydraulic control arrangement has several parts groups that must be ordered as separate parts. Some of the separate parts can be installed on the machine or modifications can be made to the former parts so they can be used again. This instruction gives the procedures to make the modifications to the former parts and to install the hydraulic arrangement.
NOTE: Before a ripper can be installed, a rear frame reinforcement group must be installed on the machine; see Special Instruction Form SMHS8208 for the correct installation procedure for the rear frame reinforcement group.
