DJUSTMENTS
Steering Lubrication
The steering axles, pivot shafts, and front caster axles must
be lubricated after every 25 hour of operation. Lubricate
using a pressure grease gun and Cub Cadet 251H EP
grease, or an equivalent No. 2 multipurpose lithium grease.
Working from the rear of the tractor, apply grease
•
through the two lube fittings on each end of the pivot
bar. See Figure 6-3.
Figure 6-3
Working at the front of the tractor, apply grease through
•
the lube fitting for both caster wheel axles. Figure 6-3.
Lubricate Rear Wheel and Caster Wheel Bearings
Lubricate the rear wheel bearings with Cub Cadet 251H EP
grease, or an equivalent No. 2 multipurpose lithium grease,
after every 25 hours of operation. The lube fittings are
located in the rim hub inside each rear wheel.
Lubricate the front caster wheel bearings with Cub Cadet
251H EP grease after every 25 hours of operation.
Cleaning Steering Gears
Once a year, or if a tight spot is experienced when turning
the steering wheel, remove the steering gear cover on
each end of the rear pivot bar and clean the two steering
gears.
From beneath the cover base plate on each end of the
•
pivot bar, remove the three hex screws securing the
steering gear cover. Remove the covers and clean the
gears. It is not necessary to lubricate the gears.
Reposition each cover on its respective base plate and
•
secure with the three hex screws. Do not over tighten.
Lubricate 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.
Removing the Deck Cover
To access the blade spindles for lubrication and/or the deck
drive belt for service, the deck cover must be removed
from the top of the deck. The mower deck does not have
to be removed from the deck frame to remove the cover,
but access is improved if the deck is removed.
Working around the perimeter of the cover, remove
•
the five hex tapp screws securing the cover to the deck
housing. Refer to Figure 6-4.
Lift the front of the cover slightly, then pull the cover
•
forward to slide the tabs of the cover out of the slots of
the deck hanger plate. See Figure 6-4.
Figure 6-4
To reinstall the cover, insert the cover tabs into the slots
•
of the deck hanger plate. Lower the front of the cover
onto the deck and secure with the five hex tapp screws.
Lubricate Deck Spindles
Lubricate the deck spindles with Cub Cadet 251H EP grease
after every 10 hours of operation.
The deck spindle lube fittings are in the top of the spindle
housings, beneath the spindle pulleys. Remove the deck
cover. See Figure 6-5.
