SECTION 4: MAINTENANCE
MAINTENANCE
Proper servicing and adjustment are the key to the long life of any farm implement. With
careful and systematic inspection, you can avoid costly maintenance, time, and repair.
CAUTION
For safety reasons, each maintenance operation must be performed with tractor PTO
disengaged, mower lowered completely to ground, and tractor engine shut off with ignition key
removed.
• After using the mower 2 hours, check all bolts to be sure they are tight and check drive
belt tension.
KNIFE REPLACEMENT
IMPORTANT: Make sure that the replacement knife is the same type and similar weight as the
others on the mower. This will keep the rotor rotation balanced. Hammer blade is the standard
configuration of this mower. If required, Y-type blade is optional.
