LUBRICATION OF DRIVE SHAFT
Lubricate both ends of the drive shaft after every 50
hours of operation as follows:
• The front end of the drive shaft can be
accessed from under the hood, and the rear
end from beneath the tractor. NOTE: It may be
necessary to rotate the drive shaft to access
the grease fittings.
• Using a pressure lubricating gun, lubricate the
drive shaft with Cub Cadet 251H EP grease.
LUBRICATION OF FRONT AXLE
Lubricate the front axle pivot pin, steering knuckles,
and wheel hubs after every 10 hours of operation.
See Figure 44. Using a pressure lubricating gun,
lubricate the drive shaft with Cub Cadet 251H EP
grease.

WHEEL LUG NUT TORQUE
The front wheel bolts and rear lug nuts should be
retorqued after the first ten hours of operation and
every 100 hours thereafter, or if the wheel assembly
has been removed. Using a torque wrench, retighten
the lug bolts and lug nuts as follows:
Rear Wheels—In a staggered pattern, retorque the
rear wheel lug nuts to 60-70 ft. lbs.
Front Wheels—In a staggered pattern, retorque
the front wheel lug bolts to 60-70 ft. lbs.
TIRE MAINTENANCE
Check the tire air pressure after every 50 hours of
operation or weekly. Keep the tires inflated to the
recommended pressures. Improper inflation will
shorten the service life of a tire. See the tire side
wall, or the Tire Inflation chart, for proper inflation
pressures. Observe the following guidelines:
• Do not inflate a tire above the maximum
pressure shown either on the sidewall of the
tire or the Tire Inflation chart.
• Do not reinflate a tire that has been run flat or
seriously under inflated. Have a qualified tire
mechanic inspect and service the tire.
WARNING: Servicing tires can be dan-
gerous. Whenever possible, trained
personnel should service and mount
tires.
If you must service the tires, observe the following
safety precautions to avoid an injury or fatality:
• Make certain the rim is clean and free of rust.
• Lubricate the flanges of the rim and beads of
the tire with soap solution.
WARNING: When seating the beads,
never inflate a tire over 35 PSI. Inflat-
ing a tire with unseated beads beyond
35 PSI could break the bead or rim with
sufficient explosive force to cause a
serious injury.
• Inflate the tire to seat the beads. If the tire
beads have not seated at or before 35 PSI,
allow the tire to deflate. Reposition the tire on
the rim, lubricate the tire beads and rim flanges,
and reinflate until seated - up to a maximum of
35 PSI.
• After the beads have seated, adjust the infla-
tion pressure to the recommended operating
pressure.
• Do not use a damaged rim, or attempt to repair
a rim by brazing, welding, or pounding out.
• Make certain the jack used to raise the tractor
has a weight capacity adequate for lifting the
tractor.
• Place the tractor on a firm, level surface and
position jack stands to support the raised
tractor while repairing tires.
• DO NOT place any part of your body beneath
the tractor or start the tractor engine while the
tractor is raised off the ground with a jack.
