New Thick Blade Bar & Larger Bolts:
Early October 1996, in order to ensure an extended service life, a new blade bar was introduced
which featured larger blade bar leaf bolts (from 7/8" to 1-1/4") and a thicker bottom leaf. As a result,
longer mounting bolts (from 3-1/2" to 4") are required to ensure adequate thread engagement into the
spindle shaft.
When ordering a replacement blade bar using the original number, the new blade bar design
will automatically be sent. However, the 4 longer mounting bolts may not be included.
Therefore, when ordering a replacement blade bar, ensure that the proper length mounting
bolts (P/N 02964861 which is a 4" Bolt) are also replaced. DO NOT attempt to mount the new style blade
bar using the old shorter bolts. The best way is to always check the replacement bottom leaf thickness
as compared to the bottom leaf that was removed. If the replacement is thicker then the new longer
bolts will be needed. Another way to determine which one you have check the Leaf retaining bolt size.
