Travel Reduction Adjustment
: (Hand Control Levers)
~To improve the tracking of the Swisher ZT2452A the speeds of the two hydrostatic transmissions must be the same.
If one of the rear wheels needs to be increased or decreased this adjustment can be performed utilizing the control
linkage assembly which is the coltrol rod that connects the handle mechanism to the hydrostatic transmission. There
is one for each transmission.
~If the ZT2452A pulls to the right the left wheel will need to decrease speed and if pulling to the left the right wheel will
need to decrease speed.
~To decrease the speed in one of the rear wheels lengthen the linkage assembly between that side control handle
mechanism and the hydrostatic transmission. Do this be removing the hair pin from the contol handle end and
disengaging the control linkage from the control handle. Loosen one of the jam nuts and by lengthening this control
linkage you can decrease the speed of the hydro. Refer to the exploded view of the control mechanism on the
following pages.
~Be sure the securely tighten the jam nuts against the nut coupler on the control linkage after the desired adjustment
has been made. Reassemble and test. Repeat this process until the mower drives in a straight line.
