Transmission Lockout Levers
The transmission lockout levers disengage the hy-
drostatic transmissons. By lifting the lever on top of
the transmission and locking it into place with the
lockout cam, the hydrostatic transmissions are re-
leased to permit freewheeling. By releasing the cam
and lowering the lever, the transmissions are en-
gaged for normal operation. The transmission lever
in the LOCKOUT position is used to enable moving
the machine without the engine running (e.g., for
service). Refer to TRANSMISSION LOCKOUT in
this section for operating instructions.
Lockout Lever Location
NOTE: The transmission plunger on the side of the
transmission case (activated by the LOCKOUT LE-
VER) must be completely released during operation
of the mower, otherwise operation of the transmis-
sion will be erratic.
Cold Start Lever (Jackshaft Drive Belt Release)
The cold start lever is used for starting the machine
in cold weather [below 40° F (4° C)]. Pulling the le-
ver DOWN disengages the jackshaft drive belt.
When the jackshaft drive belt is released, the hydro-
static transmissions are removed from the engine
starter cranking load.
