MAINTENANCE
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 450 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 450 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.
BLADE TIMING AND ROTATION (FIGURE Mnt-R-0102)
Blades on multi-spindle mowers overlap cutting paths to ensure a complete cut across the width of the mower
and to compensate for blade tip wear. If a gearbox has been repaired, a blade carrier or side driveline has been
removed, or other maintenance performed which altered the factory set blade carrier timing, the blades must
be re-timed to ensure they will not collide while rotating.
