Making myself sick trying to get perfect level and pitch on a new Lazer Z deck. Concerned something might be twisted or bent. Setting the deck level side-to-side and pitched 1/4" to the front. When I measure blade heights, I'm finding two diagonal corners that are slightly high and two that are slightly low. Meaning right front and left rear are high, left front and right rear are low. When I say slightly, I'm talking 1/8 - 1/4". I get it as close as I can, and I find two of the chains on diagonal corners are tight (right rear, left front) and two on the other diagonal corners are loose (left rear, right front). The deck is easy to move by pushing on the left rear or lifting the right front. Tightening up on the loose chains starts to lift those corners which are already high. Told myself this can't be right, had the dealer look at it, they gave it back about the same. Anyone experience this? Something possibly bent? Thanks.
