Hi
For more precise details you can call Mike from Rudnicki industrials inc. in Thunder Bay. He could even build you one.
Mine is 6 ‘ wide
4.5’ tall
Bars are 2” square tubing 1/4 “ wall thickness .
Spacing is infinite .
I’ve only used it with 1 “ spacing making nice topsoil to date. Made like 11 yds so far. Next I’m going to try 2” spacing to see what it’s like .. hope to resurface my roads .
