Headquartered in Sullivan, Illinois, Hydro-Gear
®
is a world leader in the design, manufacture,
and service of quality hydrostatic transaxles for
the lawn and garden industry. The mission of
our company is to be recognized by our custom-
ers and the industry as a world-class supplier
and the quality leader in everything we do.
This Service and Repair Manual is designed
to provide information useful in servicing and
troubleshooting the Hydro-Gear ZT-2800
®
and
ZT-3400 Integrated Zero-Turn Transaxles.
Also included is a glossary of terms that are
frequently used throughout the industry and in
Hydro-Gear service publications. Understand-
ing terminology is very important!
It is necessary, and a good shop practice, that
your service area be equipped with the proper
tools and the mechanics be supplied the latest
information available. All repair procedures
illustrated in this guide are suggested, but pre-
ferred methods of repair.
Internal repair procedures require that the
transaxle unit be removed from the vehicle.
This is not a certication, test or study guide for
a certication test. If a technician is interested in
certication, they should contact an agent rep-
resenting EETC (Equipment & Engine Training
Council) at [phone] or their Hydro-Gear
Central Service Distributor. Many distributors
will be hosting certication testing. These study
guides will cover most of the products and
manufacturers in our industry.

products, please contact your Central Service
Distributor, or call our Customer Service Depart-
ment at [phone].
