CVT Drive and brake system
58
Externally repairable drive system problems:
Most of the problems listed in this section will result in a
customer complaint of low power or low ground speed.
If the tractor is difficult to push, check the brakes.
1.
Engine performance:
•
If the engine does not turn at the specified RPM,
the tractor will not travel at its designed speed.
See Figure 6.1.
•
If the engine does not produce the specified
amount of power, the tractor will not have its
designed amount of tractive force.
1a.
Find the specified engine RPM for the trac-
tor ( 3,375-3,525 RPM for the Cub Cadet
Series 1000).
1b.
Check the engine with a tachometer to
confirm that it maintains the specified RPM
under normal load.
1c.
Correct engine performance problems
before trying to diagnose drive system
problems.
2.
Check the tires: Confirm that the correct size
tires are on the tractor.
Smaller rear tires will yield lower ground speed.
Under-filled tires will put additional load on the
drive system.
•
LTX 1040 Series has 20” x 8” rear tires.
•
LTX 1050 Series has 20” x 10” rear tires.
•
SLTX 1050 Series has 22” x 9.5” rear tires.
3.
Check the brakes: See Figure 6.2.
3a.
The brake linkage applies the brakes and
disengages the drive belt. Confirm that
both parts of the linkage are moving prop-
erly.
•
When the brake pedal is released, the front drive
belt should be slightly slack.
•
The drive and brake linkages are connected in
such a way that the pedals will “see-saw”, and it
should not be possible to apply drive and clutch/
brake pedal at the same time.
3b.
If the linkage is working properly, but the
brakes seem to be dragging, check the
brake yoke. The linkage is not adjustable.
See Figure 6.3.
