deck. Always replace both blades on a spindle using

two blades having the same weight. Use only gen-

uine Bush Hog replacement blades.

A. Remove nuts from blade bolts.

*NOTE:

If the round blade holder is removed from the gearbox output shaft for any reason, it must be reassembled with

the slotted nut torqued to a minimum of 450 ft. lbs. If 450 ft. lbs. is reached and slots in the nut do not align with

the hole through the output shaft, tighten slightly more so that cotter pin may be installed. Do not “back off” on the

nut to align slots with hole.
