Parking Brake Adjustment
Brakes are subject to wear during normal use and
should be checked periodically for adjustment. To
determine if the parking brake is in need of adjustment:
•
Engage the parking brake.
•
Open both transmission bypass valves as
instructed on page 17 before attempting to push the
tractor forward.
NOTE:
There will be some resistance from the
transmissions even when the bypass valves are open.
If the tractor can roll relatively freely, adjust the parking
brake as follows:
WARNING:
Never attempt to adjust the
brakes while the engine is running. Always
turn off blades/PTO, move both control
handles into neutral position, stop engine and
remove key before dismounting.
•
Move the tractor to a smooth, flat surface.
•
Chock the left, rear tire and place the parking brake
lever in the disengaged position.
•
Remove the hubcap from the right, rear wheel.
•
Loosen, but do NOT remove, the hex screw which
secures the wheel assembly to the transmission.
•
Jack the tractor up off the ground and stabilize the
right, rear portion of it with a jackstand.
•
Unthread the hex screw loosened earlier and
remove the wheel assembly from the tractor.
•
Locate the cotter pin which secures a castle nut to
the transmission’s brake arm. See Figure 16.
•
Carefully remove the cotter pin from the castle nut
and transmission axle.
•
Discard the cotter pin
Figure 16
•
Tighten the castle nut 11 inch-pounds, or until the
brake arm has minimal up-and-down movement
when you attempt by hand to pivot it.
•
Back the castle nut off 1/3 turn before inserting a
new cotter pin (Part Number 714-0507) to secure it
in place.
•
Remount the tractor’s wheel assembly and repeat
the previous steps on the left side of the tractor.
IMPORTANT:
Be certain to torque the hex screw which
secures the wheel assembly to the transmission to
between 25 foot-pounds and 42 foot-pounds.
•
Re-engage the parking brake and test it by
attempting to push the tractor forward.
•
If the tractor’s parking brake should need further
adjustment, see your White Outdoor dealer.
SECTION 8:
MAINTAINING YOUR LAWN TRACTOR
WARNING:
Before performing any
maintenance or repairs, always turn off
blades/PTO, move both control handles into
neutral position, stop engine and remove key
before dismounting.
Engine
Refer to the Briggs & Stratton Operator/Owner
Manual for engine maintenance instructions.
Check engine oil level before each use as instructed in
the Briggs & Stratton Operator/Owner Manual packed
with your unit. Read and follow instructions carefully.
Changing Engine Oil
•
Unscrew oil fill cap and remove dipstick from the oil
fill tube. See Figure 17.
•
Pop open the protective cap on the end of the oil
drain valve to expose the drain port. See Figure 17.
•
Push the drain hose (packed with this manual) onto
the drain port. Route the opposite end of the hose
into an appropriate oil collection container with a
capacity great enough to collect the used oil
(approximately 48 oz. on single-cylinder engines
and 64 oz. on twin-cylinder engines).
•
Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 17.
•
Service the oil filter (if so equipped) as instructed
in the separate Briggs & Stratton Operator/Owner
Manual packed with your unit.
Perform the above steps in the opposite order after oil
has finished draining.
