This 81 page, 1965 John Deere 93 and 95 Backhoe Service Manual was originally published by the Deere & Company in 1965. The original manual is no longer in print but it is available as a high high quality reproduction of the original.
The 93 Backhoe is a single-position machine and the 95 Backhoe is a multi-position machine that can be offset for digging next to buildings, walls, or foundations.
Double-acting hydraulic cylinders are used in four ways on the 93 and 95 Backhoes. Two cylinders are used to raise and lower the stabilizers; a boom cylinder is used to raise and lower the boom; a crowd cylinder is used to move the dipper-stick in or out; and a bucket cylinder is used to move the bucket to the dump or load positions.
A rotary, vane-type, cylinder is used to swing the boom during operation. A hydraulic swing brake is built into the swing cylinder to automatically slow the boom when it travels too far to the right or left.
The John Deere 93 and 95 Backhoes operate with two-lever control. The two-lever control, with its universal joint type hookup, provides eight operations. Both operating control levers provide normal simultaneous operation with minimum fatigue and effort to the operator. Two shorter levers operate the stablizers which are individually controlled.
The John Deere Backhoes can be used for a great variety of jobs, in addition to digging and loading dirt and other materials. They are adaptable to any trenching Job, such as working in cramped quarters, trenching sidewall excavations, or cleaning highway culverts.
This 1965 John Deere 93-95 Backhoes Service Manual provides detailed service information, step-by-step repair instruction and maintenance specifications. Specifically it covers Contents and Introduction, Description and Operation, Lubrication and Periodic Maintenance, Trouble Shooting, Swing Cylinder, Control Valves, Hydraulic Cylinders, Pumps, Selector Valve, Relief Valves and Bypass Flow Regulator.
