Foreword :

READ THIS MANUAL carefully to learn how to operate and service your machine correctly. Failure to do so could result in personal injury or equipment damage. This manual and safety signs on your machine may also be available in other languages. (See your John Deere dealer to order.)

• THIS MANUAL SHOULD BE CONSIDERED a permanent part of your machine and should remain with the machine when you sell it. MEASUREMENTS in this manual are given in both metric and customary U.S. unit equivalents. Use only correct replacement parts and fasteners.
• Metric and inch fasteners may require a specific metric or inch wrench. RIGHT-HAND AND LEFT-HAND sides are determined by facing in the direction of forward travel. WRITE PRODUCT IDENTIFICATION NUMBERS (P.I.N.) in the Machine Numbers section.
• Accurately record all the numbers to help in tracing the machine should it be stolen. Your dealer also needs these numbers when you order parts. File the identification numbers in a secure place off the machine. WARRANTY is provided as part of John Deere’s support program for customers who operate and maintain their equipment as described in this manual.
• The warranty is explained on the warranty certificate which you should have received from your dealer. This warranty provides you the assurance that John Deere will back its products where defects appear within the warranty period. In some circumstances, John Deere also provides field improvements, often without charge to the customer, even if the product is out of warranty.
• Should the equipment be abused, or modified to change its performance beyond the original factory specifications, the warranty will become void and field improvements may be denied. Setting fuel delivery above specifications or otherwise overpowering machines will result in such action.
