BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox 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 until carrier breaks
loose.
BLADE CARRIER INSTALLATION
Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and
install special washer nut.
Tighten nut holding blade carrier to minimum 300 ft. pounds, strike the carrier near the hub several times with a
heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.
Retighten the nut to 300 ft. pounds. Install cotter pin and spread.
IMPORTANT: Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few hours
operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from falling.

Remove locknut from blade bolt through inspection
hole in deck of mower near the gearbox to remove

R-0022. Always replace nut when replacing blade
bolt. When installing blades be sure and check
blade bolt pivot diameter for wear. Replace bolt if
