LUBRICATION OF MAIN DRIVE SHAFT
Lubricate both ends of the main 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 by removing the six screws and the center fender cover. The drive shaft can also be accessed from the underside of 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 FWD DRIVE SHAFT
Lubricate both ends of the FWD drive shaft with Cub Cadet 251H EP grease after every 50 hours of operation. The FWD drive shaft can be accessed from beneath the tractor.
WHEEL BOLT TORQUE
The front and rear wheel bolts 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 bolts as follows:
Rear Wheels— In a staggered pattern, retorque the rear wheel bolts to 80 ft. lbs.
Front Wheels
MAINTENANCE OF THE ROLLOVER
PROTECTIVE STRUCTURE (ROPS)
Periodically (at least every six months) visually inspect the ROPS for damage and loose fasteners. If damage is noted, contact your Cub Cadet dealer.
If an accident has occurred which may have damaged the ROPS, have the ROPS thoroughly inspected by your Cub Cadet dealer.
WARNING: To ensure the structural integrity of the ROPS to provide opera- tor protection, do not attempt to straighten or weld the ROPS. A dam- aged ROPS should be replaced.
If the ROPS is removed for any reason, make sure the proper hardware is used to reinstall it, and that the recommended torque values are applied to the fasteners.
When replacing or reinstalling the ROPS, apply Loctite® 242 to the threads of the bolts and torque the bolts to 65 to 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.
