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.
