IMPORTANT:
Check the dipstick reading
be fore adding the last 1/2 pint of oil and
fill
only to the “F” mark. DO NOT
overfill the
crankcase (oil above “F” mark) as this
CAN
result in en gine overheating, loss of power,
and possible engine damage.
10. Start the engine and check for oil leaks around
the oil filter. Stop the engine, recheck the oil
level, and add oil if necessary. (When the
engine is first operated with a new oil filter, the
oil level will drop slightly as the filter is filled
with oil.)
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after
every 25 hours
of operation. Lubricate
more
often
when operating in
dusty or dirty condi-
tions
. Use SAE general purpose lithium or molyb-
denum base grease for grease fittings and light
machine oil (SAE 10) to lubricate oil points.
Lubri-
cate the locations shown in the
Chassis and
Deck Lubrication Points illustration on page
47
.
NOTE:
PTO universal joints (on the deck and
trac tor) require routine lubrication
after every 25
hours
of running time. Remove tractor PTO quick
disconnect tube assembly for easy access to
grease fittings.
NOTE:
The best way to lubricate the PTO tube
half of the universal joint assembly is to remove it
from the tractor. See instructions for removing and
install ing PTO quick coupler, refer to
Deck Installa-
tion on page 22
.
NOTE:
The ball bearings on the PTO drive shaft
are sealed and do not require periodic mainte-
nance.
Mower Deck Gearbox Lubrication
NOTE:
These instructions apply to all mower
decks with gear-driven blades. Refer to
DS52 or
DS62 Mower Deck Lubrication on page 45
for
the DS52 or DS62 deck with belt-driven blades.
Refer to
Mower Deck Spindle Lubrication on page
45
for all mower decks with belt-driven blades.
On gear driven decks, the mower deck gearboxes
(tee gearbox and blade drive gearboxes) are con-
nected as a unitized assembly, and oil flows freely
between them. The gearboxes are permanently
lubricated (oil filled) and sealed requiring no sched-
uled lubrication. However, the gearbox oil seals
should be checked
every 25 hours
for indication
of an oil leak;
particularly the lower seals
on the
blade drive gearboxes should be inspected, since
they operate in a dirty environment. If an oil leak is
noted, replace the oil seal and relubricate the
gearbox assembly as follows:
1. Remove gearbox cover (footrest). Deck orien-
tation should be the normal operating position.

2. Clean the area around the individual gearbox
cover plates to prevent contaminants from
en tering the gearcase.
3.
Remove the screws securing the cover plates
on the blade drive gearboxes.
4. Check the level of lubricant in the gearboxes.
If the lubricant is low, add SAE E.P. (Extreme
Pressure) 80W-90 (API GL-5) gear lube until
the oil level is up to (submerges) the horizontal
shaft in the gearbox (shaft parallel to cover
plate).
NOTE:
In case the gearboxes are completely
drained of oil, approximately 5 fl. oz. (15 cl) of
oil per gearbox is required to refill the gear
drive assembly.
NOTE:
Since the gearboxes are connected
as a unit by connector tubes, it is necessary to
add oil slowly. Allow a few minutes after add-
ing oil for the oil to flow throughout the assem-
bly and the oil level to stabilize before reas-
sembly.
IMPORTANT: DO NOT
overfill the deck
gear boxes. The gearbox assembly is not
