Maybe you guys can help it has me scratching my head after a year of having it I finally put on my 60 inch driveover deck on my 2370 so I go to level it I put the dial roughly on number 3 and lower the deck so I check the right side at the blade tip and its dead on at 3 inches which is perfect for me .so then I check the left side well that sides 2.25 inches which seems way off so I adjusted it using the bolt at the back top of the deck but it's so far out of adjustment the bolts almost screwed all the way in i also had to adjust the left side of the front linkage too this just seems like an awful lot of adjustment to those back 2 adjustment bolts the left side has almost no threads below the head showing and the right side has almost and inch showing and I've checked and rechecked to make sure all pins are in where they should be
