Shift Lever
Use the shift lever [1] to select the forward speed at which you wish to mow.
Do not use the throttle lever to adjust your forward speed. The throttle lever
must remain in the fast position for good mowing performance. Otherwise, cut
quality suffers.
TXE & TXF
You can shift gears without releasing
the drive clutch lever, but the
transmission may not shift smoothly if
the mower is pulling hard. For
smoother operation, release the drive
clutch lever before shifting gears.
To avoid incomplete gear
engagement, move the shift lever [1]
all the way forward or all the way
back.
HXE
Use the lower speed range for
mulching and bagging, the higher
speed range for transporting.
With the shift lever all the way back
and the drive clutch lever engaged,
the mower will move slowly or not at
all.
