Dixon ZTR 5424 - Manual (Page 35)

CARE AND MAINTENANCE
Adjustment of the drive system is limited to the actual function of the hydrostatic transmissions as
outlined below.
T-BOX TO HYDROSTAT BELT ADJUSTMENT:
Tighten the (2) J-bolts on the T-box mounting plate until each belt has 1/8th to 1/4th of
an inch free play or movement at a mid-point between the pulleys on the hydrostats and
T-box.
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 complete
servicing of the unit. 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.
