2. Using a pressure lubricating gun, apply 251H EP grease, or
an equivalent No. 2 multipurpose lithium grease through
the steering shaft lube fitting.
Deck Wheels
Each of the tractor deck's gauge wheels is equipped with a grease
fitting. Lubricate with a No. 2 multi-purpose grease applied with a
grease gun after every 25 hours of tractor operation.
Pivot Points & Linkage
Lubricate all the pivot points on the drive system, parking brake
and lift linkage at least once a season with light oil.
Adjustments
WARNING!
Shut the engine off, remove the
ignition key and engage the parking brake before
making adjustments. Protect your hands by using
heavy gloves when handling the blades.
NOTE: Check the tractor's tire pressure before performing
any deck leveling adjustments. Refer to Tires on page 25 for
information regarding tire pressure.
Seat Adjustment
Refer to the Assembly & Set-Up section of this manual for seat
adjustment instructions.
WARNING!
Before operating the tractor, make sure
the seat is engaged in the seat-stop. Engage the
parking brake. Stand behind the machine and pull
back on seat until it clicks into place.
Parking Brake Adjustment
If the tractor does not come to a complete stop when the brake
pedal is completely depressed, or if the tractor's rear wheels can
roll with the parking brake applied (and the hydrostatic relief
valve open), the brake is in need of adjustment. See your Cub
Cadet dealer to have the brake adjusted.
Wheel Alignment
The front wheels should toe-in approximately 1⁄8 to 1⁄4", as
measured across dimensions A and B. See Fig. 6-8.

Steering/Toe-in Adjustment
To adjust front wheel toe-in, proceed as follows:
1. Check the steering gear to ensure it is in the centered
position. The hole in the steering segment gear will align
with the hole in the steering housing (See Fig. 6-8).
NOTE: A 5⁄16" pin can be used in the alignment holes to
assure the steering segment is centered.
2. Mark the front horizontal diameter of both front wheels at
the same spot on each wheel-preferably the inner bead
flange of the wheel rims. Mark the rear horizontal diameter
of both front wheels in the same manner.
3. Measure the distance between the bottom edges of the
tractor frame channels and the marks on the front of
each wheel (See measurement D in Fig. 6-8). These two
measurements should be equal.
4. Measure the distance between the frame and the marks
on the rear of each front wheel (See measurement C in Fig.
6-8). Measurement D should be approximately 1⁄16- to 1⁄8-
inch less than measurement C on each side of the tractor.
5. Loosen the jam nuts from the ball joints. See Fig. 6-9.

6. Disconnect the front ball joints from the steering arms
by removing the hex lock nuts. Refer to Fig. 6-9. Manually
move each wheel to achieve the required toe-in and equal
D measurements.
7. Making sure not to move the steering gear or either wheel,
turn the ball joint in or out on each drag linkas necessary to
align with the hole in each steering arm.
8. Reinstall the ball joints in the steering arms and secure with
the hex lock nuts. Tighten the jam nuts against the ball
joints.
