Toro Zmaster double blades

[Shane Woods]

To run double blades on a Zmaster do you need to get longer bolts or are the factory bolts long enough? I have a new Zmaster and it looks like it may take at least two washers between the blades to make them fit flush because of the cradle. Also what combination of blades works best on the Zmaster? The factory blades have low lift and don't seem to discharge the grass and leaves very well. Thanks for your input and opinions on the subject.

This same topic was brought up a couple of days ago, but you probably missed it. Here is the link to it below. It sounds like you need to space this out to about 7/8" more total, so I would get bolts at least 1/2" longer.
