Hydrostatic Transmission; Cutting Blades - Cub Cadet i1050 Operator's Manual

Changing Transmission Drive Belt
Several components must be removed, including transmission
steering linkage which will have to be readjusted, in order to
change the tractor's transmission drive belt. Contact your Cub
Cadet dealer to have your transmission drive belt replaced.

Hydrostatic Transmission

Keep the area around the transmission cooling fan free of grass
and debris at all times. The hydrostatic transmission is sealed at
the factory and is maintenance free. The fluid level cannot be
checked and cannot be changed.
Cutting Deck Removal
To remove the cutting deck, proceed as follows:
1. Disengage the PTO (Blade Engage) and engage the parking
brake.
2. Place the deck gauge wheels in their highest setting
(lowest deck setting).
3. Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
4. Looking at the cutting deck from the left side of the tractor,
locate the deck support pin on the rear left side of the
deck. Refer to Fig. 7-1.

5. Pull the deck support pin outward to release the deck from
the deck lift arm. Pivot the support pin handle downward
to lock the pin in the disengaged position. Refer to Fig. 7-1.
6. Move to the right side of the tractor and repeat the
previous step to release the deck from the RH lift arm.
7. Move the deck lift lever into the top notch on the right
fender to raise deck lift arms up and out of the way.
8. Carefully slide the cutting deck forward until the front deck
hanger rod can be removed from the slots of the hanger
bracket at the front of the deck.
9. The PTO belt is captured inside the PTO pulley on the bottom of
the engine by a belt keeper. From beneath the front/left
side of the tractor, locate the hex tapping screw securing
the left side of the belt keeper to the bottom of the tractor
frame. After first noting the frame hole into which right
side of the belt keeper is inserted, remove the hex tapping
screw and belt keeper. Slide the PTO belt off the tractor's
PTO pulley.
10. While holding the front deck hanger rod upward to clear the
deck front hanger bracket, carefully slide the deck out from
the right side of the tractor.

Cutting Blades

WARNING!
Be sure to shut the engine off, remove
ignition key, disconnect the spark plug wire(s) to
prevent unintended starting before removing the
cutting blade(s) for sharpening or replacement.
Protect your hands by using heavy gloves or a rag to
grasp the cutting blade.
The blades may be removed as follows.
1. Place a block of wood between the center deck housing baffle
and the cutting blade to act as a stabilizer.
See Fig. 7-2.
Figure 7-2
2. Use a 15⁄16" wrench to loosen the hex flange nut securing the
blade to the bottom of the spindle assembly. Secure the
spindle by either holding the blade tightly, or by using a
second wrench to hold the nut at the top of the spindle.
3. Continue holding the blade onto the star hub of the spindle, and
remove the flange nut and cutting blade.
4. Repeat the previous steps to remove the other two blades.
