EQUIPMENT DESCRIPTION

Refer to TM 5-2420-222-10 for a description of the loader backhoe.

DIFFERENCES BETWEEN MODELS

Although all model JD 410 loader backhoes covered by this manual have the same model number, there are significant

differences in configuration. There are two basic configurations: early configuration, Serial Numbers 235786 thru 235999,

and late configuration, Serial Numbers 319995 thru 342573. These two configurations differ mostly in transmission design

and hydraulic line routing.

Throughout this manual, where differences in configuration or equipment affect operation or maintenance, they are shown

in detail. If differences are minor and obvious (such as exact appearance or location), and operation and maintenance are

not affected, typical equipment is shown.

EQUIPMENT DATA

Refer to TM 5-2420-222-10 for information on loader backhoe identification and data plates, and end item and component

specifications.
