DRIVE SYSTEM-IVT
Drive pedal shafts
The I-series tractors equipped with the IVT trans-
mission have two drive pedal assemblies. The main
drive pedal shaft is attached to the forward drive pedal.
It operates the brakes and pulls the drive control links
in the forward direction. The reverse drive pedal shaft
is geared to the main drive shaft. When the reverse
pedal is depressed, the reverse drive pedal shaft will
rotate the main drive pedal shaft in the reverse direc-
tion.
To remove the drive pedal shafts:
1.
Remove the deck as described in chapter 8 Cut-
ting Decks and Lift Shaft.
2.
Remove the fender by following the steps
described in Chapter 4: Body/Chassis.
3.
Put a timing mark on the gears of the two shafts.
•
One mark on the fourth tooth from the bottom of
the reverse gear.
•
One mark on the fourth valley from the valley of
the main drive shaft gear. See Figure 5B.42
Timing marks
Figure 5B.42
NOTE: The timing marks will make re-assembly
easier.
4.
Remove the reverse drive pedal:
NOTE: If the main drive pedal shaft is the only
part that needs to be serviced, the reverse pedal
shaft can be left in place. However Cub Cadet
recommends removing the reverse pedal shaft
and replacing the bushings at the same time.
NOTE: Worn bushings on either drive pedal
shaft will cause some loss of wheel speed.
4a. Remove the hair pin clip and washer.
