1. Safety
1.1. Before servicing the Big Country, technicians
should be familiar with the vehicle and the Operator’s Manual that applies to it. There are important instructions that pertain to safe and correct
operation and service of the Big Country contained in the Operator’s Manual
1.2. The procedures in the Service Manual
ten with the safety of the technician and operator
as a primary consideration. Failure to follow
these procedures may create a dangerous condition.
1.3. There is no substitute for common sense.
2. Model and Serial Numbers
2.1. The engine and transmission are components
that Cub Cadet has purchased from outside
sources and incorporated into the Big Country
utility vehicle. The Chassis, engine, and transmission each have separate model and serial
numbers.
2.2. To make parts identification easier, and to
accommodate warranty administration, the
chassis numbers should be recorded in the
Operator’s Manual as well as the sales receipt.
2.3. Chassis Identification: The model and serial
number of the Big Country are located on a tag
on the bottom of the plate that driver’s seat is
mounted to. Tilt the seat forward to view the tag.
See Figure 2.3.
.
are writ-
2.4. If the tag comes off, or if the seat plate is
removed, the servicing dealer can get a new tag
issued by calling Cub Cadet.
2.5. The servicing dealer must be able to identify a
Big Country by model and serial number in order
to perform warranty service on that unit.
2.6. Engine Identification: The engine serial number
is located behind the starter motor.
See Figure 2.6.

4. Special Tools
NOTE: We are not in the tool business. Where
special tools will make a specific job easier for
the technician, we offer them.
4.1. Shock and Spring Unit Removal and Installa-
tion Tool: Part Number 703-05103 is designed
to hook into the upper spring and shock
absorber mount on the drive axles.
See Figure 4.1.
Shock and Spring Unit Tool
Part Number 703-05103
3. Fasteners
3.1. A combination of metric and SAE fasteners are
used to assemble the Big Country. If a metric
tool size is specified in this manual, the fastener
will be metric. If fractional inch tool size is specified in this manual, the fastener will be SAE.
3.2. When servicing a Big Country it is important to
replace locking hardware when it is worn. Lock
washers should be replaced if they show any
sign of flattening. Nylon insert lock nuts and
center-lock nuts should be replaced when they
get easy to turn. The bolts used in conjunction
with center-lock nuts are also subject to wear.
They should be replaced if the thread profile is
noticeably worn. Any hardware that shows signs
of wear, stripping, or stretch should be replaced
in the course of normal service. If locking hardware is not readily available, thread locking
compound such as Loctite 242 (blue) should be
used.
3.3. All torque specifications will be given in inchpounds or foot-pounds, whichever scale is
appropriate for a particular fastener. This
includes metric fasteners.
Figure 4.1
4.2. Use the dowel to hold the spacers in position on
each side of the top mounting point of the spring
and shock absorber unit during the removal and
installation process. See Figure 4.2.

Section 2: Clutch, Transmission, Brakes, Linkages
Section 2: Clutch, Transmission, Brakes, Linkages
1. Shift Linkage
NOTE: The shift linkage and brake linkage of the
Big Country are tied together by a shift interlock
mechanism that prevents the operator from
shifting gears while the vehicle is in motion. The
brake pedal must be depressed before the gearshift lever will move. The effect is the same
whether the brake is held down by the operator’s
foot or by the parking brake.
NOTE: A clutch pulley brake operates in unison
with the vehicle brakes inside the transmission.
The purpose of the clutch pulley brake is to
insure that the input shaft of the transmission is
not rotating when the operator shifts gears. This
prevents gear “crunch” on engagement, and
improves transmission life.
NOTE: The shift lever is the longer of the two
levers located between the seats. The shorter
lever is the differential lock. See Figure 1.0.
Reverse
Shift Lever
2. Shift Linkage Removal and Replacement
NOTE: If an operator has tried to shift gears
without using the brake or if the interlock
mechanism is out of adjustment, shift linkage
damage may occur.
2.1. Turn the engine off, remove the key, put the
transmission in neutral, and set the parking
brake.
2.2. Lift and secure the bed.
2.3. Fold both seats forward.
2.4. To reach the shift lever and the front of the shift
rod, remove the bolt that fastens the cup holder
between the seats using a 3/8” wrench.
See Figure 2.4.

NOTE: The lever should click firmly into each of
the three positions without hitting the end of its
travel.
NOTE: The travel of the shift lever should be
centered in the slot.
NOTE: If an extreme amount of adjustment is
necessary to center the gearshift lever, the linkage may be damaged.
2- 3
Section 2: Clutch, Transmission, Brakes, Linkages
NOTE: When the brake is released and a gear is
engaged, the pin that connects the clevis to the
transmission shift lever should be centered in a
slot in the interlock arm. If it is not, refer to the
“Shift Interlock and Clutch Brake Adjustment”
section of this manual.
NOTE: When the parking brake is set, the shift
lever should move between gears without catching or dragging against the interlock arm. If it
does not, refer to the “Shift Interlock Adjustment
and Clutch Brake Adjustment” section of this
manual.
4. Checking Operation of the Differential Lock Mechanism
4.1. Lift and safely support the drive wheels of the
Big Country according to the procedures listed in
the “Lifting the Big Country and Removing the
Drive Wheels” section of this manual.
NOTE: Operation of the differential lock mechanism may be tested by manually rotating the
drive wheels.
4.2. With the differential lock released both drive
wheels on eather side of the vehicle should spin
when either the front or rear drive wheel is
rotated by hand. The drive wheels on the other
side of the Big Country should remain stationary.
4.3. With the differential lock lever pulled-up roughly
half the length of the slot that it travels in, all four
wheels should rotate if any one wheel is turned
by hand.
4.4. The differential lock should engage within 90
degrees of front drive wheel rotation.
NOTE: Internal transmission damage, or collision damage may result if the differential lock
lever is not operated in accordance with the
instructions in the “Big Country Operator’s Manual”.
NOTE: It is normal for the steering abilities of
any six-wheeled vehicle to be greatly diminished
while the differential is locked.
NOTES
5. Differential Lock Linkage Removal and Replacement
5.1. To reach the differential lock cable, Perform
steps 1 through 7 of the “Shift Linkage Removal”
section of this manual.
5.2. To remove the cable, loosen the jam nuts that

lock bracket. See Figure 5.2.
Differential Lock Bracket
4.5. Once engaged, it will remain engaged even if
the lever is released, as long as there is a difference in the drive load between the left and right
sides of the vehicle.
NOTE: In service, differences in drive load
would result from greater traction on one side
than the other, attempting to turn the vehicle
while the differential lock is engaged, a dragging
brake on one side or the other, or grossly different air pressures in the tires from one side to the
other.
4.6. When the drive load is equalized from left to
right, the differential lock will automatically disengage if the lever has been released.
