Thank you I'll start getting parts list together. The adjuster lock nuts and screws were seized and would not budge for 3 days with WD40 and gentle back and forward action to get them moving. I had not intended to use a hammer as a routine course of action but to see if when the adjuster was backed off the reel would move closer to the blade as it was fixed in place and not moving with the adjuster backed off. I will adjust the bearing carrier bolts. On reassembly i will replace the adjusters and all bearings. Thank you for giving me an indication of the vintage of the mower. I had thought it would be older but a hard life ages everything. Since the initial mow on the purchase day and the discovery of the clutch damage the mower has been out of service. Pending investigations into repair costs ect. mower height of 30 to 50mm are recommended for buffalo grass leaning toward the upper end. My lawn is not old enough to be heavily thatched and in manny places was showing dirt after being mown on the highest setting with the SB. Being in much better condition will alter the cutting action and performance of the mower. However short Sir Walter in hot Queensland weather will soon burn off.
