ADJUSTMENT POINTS FOR
T-BOX BELT TENSION
Each hydrostat has a bypass relief pin located at the rear of the
hydrostatic unit. A bypass keeper is provided to allow the mower to be
rolled around without engine running. To accomplish this, the bypass
keeper springs must be positioned to depress the bypass relief pins.
Remove bypass keeper springs prior to actual operation of the mower.
