provided with mower.
Initial Start and Hydrostat Transmission Check:
1. Final hydrostat checks have been performed at the factory, however, it is
necessary to check that the pressure relief bypass on each hydrostatic
transmission is completely released before attempting to drive mower.
2. Each hydrostat has a bypass relief pin located at the rear of each hydrostatic
unit. A bypass keeper is provided to allow the mower to be rolled around without
complete servicing of the unit. To accomplish this, the bypass keeper must be
positioned to depress the bypass relief pin. After the use of bypass keeper, each
must be removed from the bypass relief pin before the unit can be operated.
