Installation

1. Align the blade holder so the cotter pin hole is positioned 90º to the blade bar (for ease of installing the
cotter pin).
2. Place blade holder assembly, washer, and retaining nut on lower shaft. Torque nut to 450 ft. lbs. Strike the
head of the blade bolt with a sledge hammer on one side and then the other. this will help seal the pan to
the gearbox output shaft. Always recheck the torque of the nut after using the sledge hammer.
3. Install cotter pin. It may be necessary to tighten nut slightly to install cotter pin. Always tighten slightly more
so that the cotter pin may be installed. Do not "Back Off" on the nut to align slots with hole.
NOTE: After a few hours of operation always recheck blade carrier retaining nut torque.
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.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
