Service Manual

PREFACE
The rear drive system on Toro Commercial Rear Drive Walk Power Mowers has
been improved almost yearly since
its introduction in 1983. While the result is a
very durable, high quality mower, servicing can be difficult because of the many
improvements and parts cross-references.
The purpose of this guide is to aid in servicing the rear drive system on 1983
through 1989 Toro Commercial Rear Drive Mowers. We’re hopeful that
it will:
1. Inform you of the most effective way to rebuild the Toro
Commercial Rear Drive System.
2. Reduce time spent paging from cross reference to cross reference
in the parts catalog.
3. Help reduce your parts stock by indicating obsolete parts.
This document supercedes Commercial Rotaries Service Bulletins 13 and 16
regarding rebuilding the rear drive system. However, use of the rebuild kits
referenced in Service Bulletin number 17 is still highly recommended whenever
output shaft replacement becomes necessary.
