Dixon ZTR 5424, ZTR 5020 manual Care And Maintenance, T-Box To Hydrostat Belt Adjustment

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.
