Introduction
INTRODUCTION
THANK YOU for purchasing a John Deere product.
Read this manual and your vehicle manual
thoroughly. Failure to do so could result in personal
injury or equipment damage.
This manual should be considered a permanent part of your
attachment and should remain with the attachment when you sell
it.
Measurements in this manual are metric units and their U.S.
customary equivalents. RIGHT-HAND and LEFT-HAND sides
are determined by facing in the direction the machine will travel
when going forward. When you see a broken line arrow (----->) it
indicates the part it is pointing to is hidden.
Record identification numbers below. Be sure to record all the
numbers to help in tracing the attachment if it is stolen. You also
need to give these numbers to your John Deere skid steer dealer
when you order parts.
