IMPORTANT NOTE:
BOLTS of different lengths are used for the installation of the blade bar or pan blade carrier
attachement to the spindle shaft. The required length is dependant on which carrier is used. DO NOT
change the length of the bolts on the carrier installation, use only the length that came with the mower.
The spindle shaft and spindle componets can be damages if longer bolts are used as well as the blade
carrier can not be torqued porperly. See Parts Manual for correct part numbers. (figure 34)
DO NOT mix old and new blades on same blade carrier, Blades MUST be equal in weight to
maintan carrer balamce. If A vibration exist in the blade carrier the balance is off. The problem causing
the out of balance condition must be corrected. If mower is run without correcting balance problem
damage will be done to the deck and other components. The extend and speed of the damage will
increase with the severity of the unbalance problem.
