I have a 52" Lazer with 1500 hrs. and the cut is still excellent. I have a fireball dedicated rotary blade grinder and mag-o-matic balancer and all my blades have been sharp and well balanced. Last week I had a electric pto clutch go out and took it in for replacement. Exmark provided a loaner machine with only 13 hours for use (many thanks) and I noticed the deck ran much quieter and when desingaged the pto button at 1/2 throttle that the sound of the deck is amazingly much quieter than my 6 yr. old mower. I have gotten used to the sound of the old unit and am conserned about spindle replacement. How many of you exmark users replace the spindles and how ofter. I do not mind spending the money or doing the work, just need opinions. My spindles are the no zert type from factory. I also run a exmark walk behind, 36" full floater with 15 hp kaw., another fine piece of machinery. Nobody but myself has run the lazer rider but me.
