Introduction

This backhoe, in addition to its outstanding digging characteristics. can be shifted from side to side. The backhoe can be shifted in either direction without the operator leaving his seat. The total amount of shift from one side to the other is 46 inches.

Once shifted, the backhoe is held in position by four hydraulic locks. The locks are pressurized when the bucket is extended. Thus the hydraulic locks are frequently repressurized during backhoe operation, virtually eliminating any possibility of slippage.

The six-section control valve, located in the mounting frame, regulates and controls the hydraulic operation of the backhoe. This valve contains a regenerative system that eliminates cavitation (voids). Parts subject to high "mechanically" produced pressures are protected by secondary relief valves. Operation of this valve is explained on pages XIV-7 to XIV-11.
