Should have been watching these closer top bearing went out and damaged the shaft and the pulley.wall A new scag idea of having spindles with NO grease zerts. Here is list of parts needed. Lasted a couple years at about 15 hours a week. Total $94 If I had inspected weekly ....2 bearings cost $14 ...one hour labor. If I can get the inside dust cover off the bearings I will add zert.
