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.
