John Deere 318 - Manual (Page 353)

BEFORE YOU START
Always begin with this group to identify a failure in
the power train. The step-by-step procedures will
provide you with a quick check of the system. No
tools are required to perform these checks. If a failure
is indicated, you will be referred to a more detailed
check, adjustment, or test.
Always start with the first step and follow the
sequence from left to right. Read each step
completely before performing the check.
This procedure is designed as a quick check of the
system. While performing the check, concentrate only
on the check you are performing and disregard
signals from unrelated components.
