Service Dealer - Cub Cadet RZT54 Operator's Manual

The cutting blades must be kept sharp at all times. Sharpen
the cutting edges of the blades evenly so that the blades
remain balanced and the same angle of sharpness is
maintained.
If the cutting edge of a blade has already been sharpened
many times, or if any metal separation is present, it is
recommended that new blades be installed. New blades are
available at your authorized dealer.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor, (refer
to Deck Removal) then gently flip the deck over to
expose its underside.
2. Use a 15⁄16" wrench to hold the hex nut on top of the
spindle assembly when loosening the hex nut securing
the blade. A block of wood may be placed between
the deck housing and the cutting edge of the blade to
help in breaking loose the hex nut securing the blade.
See Figure 7-7.

3. When reinstalling the blades, be sure they are installed
so that the wind wings are pointing upward toward
the top of the deck.
4. Tighten the blade nuts to 70-90 ft. lbs.
5. Reinstall the deck (refer to Deck Installation).
Changing the Transmission Drive Belt
Several components must be removed and special tools used in
order to change the tractor's transmission drive belt. See your
authorized dealer to have the transmission drive belt replaced.
Wood Block
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 opened out 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.
1. Place the front of the tractor against an immovable
object (e.g. wall, post, etc.).
2. Jack up the rear of the tractor so that both rear
wheels are approximately one inch of the ground.
3. 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.
4. If only one wheel is rotating, locate the transmission
control rod beneath the frame at the front of the rear
tire. If both wheels rotate, locate both control rods. See
Figure 7-8.

5. Remove the flange lock nut and hex screw securing
the transmission control rod to the transmission control
arm. Wheel rotation should stop. If it does not, contact
your Service Dealer.
6. If the rotation stops, adjust the control rod up or down
as necessary to align with the hole in the transmission
control arm. Re-insert the hex nut into the hole in the
control arm and secure with the hex lock nut.
7. If necessary, repeat the previous two steps to adjust
the other transmission control rod.
8. Lower the tractor and remove the jack.
