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, and 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.
Operating the mower with a loose blade pan or holder can damage the taper connection on
the gearbox output shaft. To ensure proper seating between the blade holder and output
shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade
carrier attachment each morning before operating. Grasp the carrier firmly with both hands
and try to push and pull the carrier with one hand while pulling and pushing with the other
hand to try to rock or oscillate the blade carrier. If the carrier is loose, retighten the retaining
nut before operating the mower.
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.
