Cub Cadet RZT 50 (w/50" Mower Deck) Operator's Manual page 23

If you have a recurring problem with blown fuses,
have the tractor's electrical system checked by your
Cub Cadet dealer.
Relays and Switches
There are several safety switches in the electrical
system. If a function of the safety interlock system
described earlier is not functioning properly, have the
electrical system checked by your Cub Cadet dealer.
LUBRICATION
• Using a pressure lubricating gun, lubricate the
front castor axles and pivot axle with Cub Cadet
251H EP grease after every 10 hours of service.
• Refer to the "MOWER DECK" section later in this
manual for deck lubrication procedures.
• Periodically lubricate all other pivot points with a
quality lubricating oil.
TIRE MAINTENANCE
Check the tire air pressure after every 50 hours of
operation or weekly. Keep the tires inflated to the rec-
ommended pressures. Improper inflation will shorten
the tire service life. See the tire side wall for proper
inflation pressures. Observe the following guidelines:
• Do not inflate a tire above the maximum pressure
shown on the sidewall of the tire.
• Do not reinflate a tire that has been run flat or
seriously under inflated. Have a qualified tire
mechanic inspect and service the tire.
USING THE TRANSMISSION BYPASS RODS
If for any reason the tractor will not drive or you wish
to move the tractor, the two hydrostatic transmis-
sions are equipped with a bypass rod that will allow
you to manually move the tractor short distances.
WARNING: Do not tow the tractor, even
with the bypass rod engaged. Serious
transmission damage will result from
doing so.
• From just in front of the two rear tires, locate the
transmission bypass rods. See Figure 26.

• Pull one rod toward the front of the tractor until
the flange on the rod is forward of the keyhole
slot in the frame assembly.
• Lower the bypass rod into the keyhole slot and
release so the rod flange is against the front of
the frame bracket.
• Repeat the above procedure to engage the other
bypass rod.
• After moving the tractor, disengage both bypass
rods. Lift the rod and guide the flange of the rod
back through the larger circular opening of the
keyhole, then release the rod.
IMPORTANT: The tractor will not drive with the
bypass rods in the engage position.
TRACTOR CREEPING
Creeping is the slight forward or backward movement
of the tractor when the engine is running at high idle
and the drive control levers are in the neutral position.
If after operating the tractor for some time, it begins to
creep while in the neutral position, adjust the
transmission control rods as follows.
• Place the front of the tractor against an
immovable object (e.g. wall, post, etc.).
• Jack up the rear of the tractor so that both rear
wheels are approximately one inch of the ground.
• With the engine running at high idle and the drive
control levers opened out in the neutral position,
and the parking brake disengaged, check the rear
wheels for rotation.
• If only one wheel is rotating, locate the transmis-
sion control rod beneath the frame at the front of
the rear tire. If both wheels rotate, locate both
control rods. See Figure 27.

• Remove the internal cotter pin securing the
ferrule to the transmission control arm and
withdraw the ferrule. Wheel rotation should stop.
If it does not, contact your Cub Cadet dealer.
