to removed blades for sharpening or replacement, remove the cover plate on deck of cutter near
each gearbox. remove locknut from blade bolt. inspect lock nut after removal and replace if threads
or nylon insert are damaged. always replace nut when replacing bolt. When installing blades, be
sure to check blade bolt pivot diameter for wear. replace bolt if worn more than 1/4 at any point.
install blade bolts with worn side of bolt away from the center of the blade carrier. tighten lock nut
to 300 ft. lbs.
avoid personal injury. Blade and/or bade carrier removal should be done only with the tractor
engine shut off, key removed, in neutral, parking brake on, pto disengaged, and the cutter blocked
in the raised position. avoid personal injury. Do not work under cutter without support blocks to
keep frame from falling.
BLade Carrier reMovaL
remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut
until the blade carrier is loosened. use a suitable two-jaw gear puller to pull carrier tapered gear box
shaft. if gear puller is not available use long bar inserted through blade bolt access hole with end
against rotor bar. Strike opposite end of bar with sledge hammer. rotate blade carrier 180 degrees
and repeat process.
Hardware
Check nuts, bolts, and other miscellaneous
hardware regularly. Loose hardware is easily
lost, cause increased wear on parts, and increase
the chance of breakdown. Loose hardware creates
potential hazards which could result in personal
injury to the operator, support personnel and
bystanders. use the “torque Chart” below when
tightening bolted connections.
