GENERAL INFORMATION
This section is devoted to digging chain options for your trencher. In
it you will find a listing of all the chain options available. You will also find
information on replacement parts, chain assembly, and chain conversion.
These options will increase the flexibility of your equipment, and make your
trenching job easier.
There is some basic information about the trencher and it's digging
components that you should know before you try to order any options. This
information is given here for your convenience. With it you will be able to
better understand the rest of this section.
CHAIN PITCH
The digging chains may be divided into groups by pitch. The pitch of
the chain is the distance between the centers of the holes in the chain links
(See Figure 1). The word pitch can also be used to describe the length of
the chain.

The 617 Trencher has a heavy weight chain with a tensil strength of
50,000 pounds and a pitch of 2.00".
There is one thing that you must understand about chain pitch. You
can not intermix components of different pitches. You cannot substitute
chain links of different pitches in a digging chain. Nor can you use a dig-
ging chain of one pitch, with a driver sprocket of a different pitch. Attempt-
ing to do so will cause the chain to "jump" off the sprocket continuously.
