To all you Lazer Z owners out there I was wondering what the ratio of gater blade users v/s stock high lift blades are and what your opinions are of each? Also has anyone tried using the double blade system that has been a topic of conversation on this forum before on the Lazer Z's and how did you install them? Were you happy with the results? Thanks in advance for any replys

I have a laser and I have been using the double blades for about two months. They seem to work good and chop up pretty much everything in its way. I have gators on the bottom and high lifts on the top. I put them in a + formation and just removed the washer(you need the extra threads on the bolt) Put them in a + and tightened them with an air gun. They stay in the +, believe it or not!! YOu can go to Eric's site if you want a little more detail, or just type in double blades, because this topic has been talked about a lot!!

This has to be about one of the most UNSAFEST practices I've ever heard of. If you're going to run double blades on a Lazer, DO NOT remove the washer- since this is so crucial in distributing presure on the blades and holding them in place. If the blade happens to move even just a litle on the bolt, the bolt and whole a s s embly could come loose and become DEADLY! To run doubles, you have to put a longer bolt in to hold the threads. It's a 5/8 X 1 1/2" 11 thread per inch is what you are looking for. And make sure it's ATLEAST a #8 hardened bolt. This also gives you 1/4" more thread up inside the spindle than the factory bolts have.

If the Lazers have a 5/16" bolt, I wouldn't even put one blade on it. I'm hoping you meant 5/8" bolt, which is what most commercial mowers have on them.

Eager Beaver, I have used double blades for a long time and I've tried double Gators on grass and they didn't do to good, so I figure one set of Gators would be twice as bad. I only use them along with a Highlift blade for cutting grass. A Gator doesn't slow down the RPM's as much, so that is why I like them with using doubles. Double Gators on leaves works OK though.

I've been running double blades on my Lazer Z all season. Tried different combos. Personally I like gators on top with Exmark mulching blads on bottom.

I use the original 5/8 bolts. Like runner said, make sure you use the washers. I haven't found it necessary for a longer bolt. You're only losing 3/8 of an inch using an additional blade. Just make sure you use a torque wrench and tighten them to what the manual says.

I have found gators to be good only on leaves. Unless to use them with highlift blades. Gators just will not leave a smooth looking cut. Now the gator magnums may work. I haven't tried them. But adding lift to the gators will cut down on the rpms and cut down on the chopping effect.
