Anyone on here with a Next Lazer Z A/S use different blades than the ones that came on it? I have the A/S 60" w/ a 25 HP Kohler and would like to know what other blades are used on it. I don't cut for a "living", just here at home. I don't bag either if that makes a difference. I'm use to the blades that were on my TANK M48, they seemed heavier. The "stock" blades on the Lazer Z A/S seem to be light, easier to beat up. Here at the house I really don't cut anything rough, rocks etc...lots of molehills though. I do flatten them out 1st most of the time. Any help is appreciated. Thanks.
